What is BF Cache? Exploring the Key Benefits of Using BF Cache for a Better User Experience

The bf cache (back / forward cache) is a web browser optimization that is used to enable instant back and forward navigation. It improves the browsing experience, especially for the user who has a slower network or has a slower device.

bf cache

According to Chrome Usage Data, 1 in 10 navigation on desktop and almost 1 in 5 on mobile are either back or forward. Now, how can you ensure that after navigating back and forward to the web page, they load immediately? That is when the bf cache comes into play! 

Here we will cover the concept of bf cache and the key benefits of using this for a better user experience. 

What is bf cache?

A bf cache (also known as back/forward cache) is a feature that allows the browser to create a snapshot of a visited web page and store it in their in-memory. It is used when the user navigates back or forward between the web page.

Let’s understand it with an example, suppose you have performed a Google search to find some information & clicked on a particular search result to find the some information, but you are not happy with the information & press the back button to go back to the search results, now instead of loading the page again the browser would show saved snapshot.

When a user visits a web page, the browser first downloads and parses the resource files of the content such as HTML files and CSS stylesheets. Then render the webpage content. And finally, JavaScript makes the page interactive.

If the back-forward cache is not enabled for a web page, that means every time the user leaves the page and navigates back to it, the browser will go through the whole process. It will decrease the pagespeed performance of the website.

Which browsers support bf cache?

In web technology, bf cache is not a new concept. Safari (a web browser developed by Apple) added this feature in 2009. 

Now, almost all browsers support the back/forward cache. Here we are mentioning some popular browsers.

  • Chrome
  • Firefox
  • Edge.

The difference between an HTTP Cache and a bf Cache?

  • HTTP cache or disk cache is used to store the static resources of the webpage content such as HTM files and CSS files to avoid the redownloading of these static resources. 
  • Whereas the bf cache is more comprehensive. It stores the snapshot of the entire webpage including JavaScript in the in-memory.

In the HTTP cache, not all static resources are allowed to be cached. As a result, every time the user visits the website, the browser needs to re-download the content. With the help of the bf cache, this issue can be avoided. 

How to check if your website can be served from the bf cache?

There are various ways that you can check if your website can be served from the backforward cache or not. Here we would check this in two most popular ways to check the website.

  • Using Chrome DevTools:

Chrome DevTools allows you to check whether the web page is eligible for the bf cache. To check this you need to follow these 5 steps.

Step 1: Visit the page you want to test in Chrome DebTools.

bf cache step 1

Step 2: Right-click on the page and click on Inspect option or you can press F12.

bf cache step 2

Step 3: click on the Application option.

bf cache step 3

Step 4: Select the Back/forward cache in the Background services sections.

bf cache step 4

Step 5: Click on Test back/forward cache

bf cache step 5

Then DevTools allows you to see the status indicating whether the website can use bf cache. 

  • Using Google PageSpeed Insights: 

Another option is to use Google PageSpeed Insights, to check if the website can be served from the back forward cache or not.

If the tested web page cannot be restored from the bf cache, the audit will fail. By clicking on the warning, you can see a drop-down menu with the failure reasons.

These failure reasons can be categorized into three parts.

 Actionable indicates you can make changes to the website to support the back-forward cache.

Pending Support shows that the web page isn’t eligible for the bf cache for now. But in the future chrome supports it.

Not Actionable indicates you can’t fix this issue on the webpage. 

The Most common issues that prevent bf cache

At this point, you have a brief idea about the bf cache. The main reason that prevents bf caching are:

  • Using Cache-Control: no-store header in your JavaScript code

The Cache-Control HTTP header holds the instructions for both HTTP requests and HTTP responses. No-store header in cache-control will disable all caches. 

cache control
  •  Using Unload event in JavaScript:

The unload event occurs when users navigate away from the web page such as submitting a form, clicking a link, entering a new URL, etc. 

During the unload event JS code can execute the task before the web page unloads such as saving the data. 

5 Strategies to optimize a web page for bf cache 

Here we are mentioning the best strategies that you can apply to fix the issues that prevent back forward cache.

1. Use cache-control: no-store only for the information-sensitive page 

If the webpage contains some sensitive information and caching is not needed then use cache-control: no-store to prevent it from being eligible for the bf caching.

Code for node js server:

app.use((req,res,next) => 

{

res.setheader(‘Cache-Control’, ‘no-cacche’);

next();

});’

For a wordpress website, you can use plugins like Cache-control, Cache control by Cacholong, LH Add Headers, etc. to optimize a web page for bf cache.

On the other hand, if the content of the web page is not static then also cache-control: max-age() is used.

2. Update sensitive data after bf cache restore to optimize a web page for bf cache

A bf cache should not be used on web pages that contain sensitive data. Especially when a user visits the website from a public computer, the next user should not be able to visit that page by just clicking the back button.

componentDidMount() {
console.log('componentDidMount')
window.addEventListener('pageshow', (event) = {
console.log('PAGE_SHOW');
if (event.persisted) {
console.log('PAGE_SHOW_PERSISTED');
}
});
}

 You can achieve this by using event.persisted after a pageshow event.

3. Avoid using the unload event to optimize a web page for bf cache

The most common way to optimize the bf cache is to avoid using the unload event. Instead of using the unload event, you can use the pagehide event in the method like addEventListener() to detect when a webpage is visible or hidden to a current user.

window.addEventListener('click', warnAboutLostChanges);

function bindWarnAboutLostChanges() {
  window.addEventListener(
    'beforeunload',
    function(e) {
      if (shouldWarnYouLogic()) {
        e.preventDefault();
        return "You have unsaved changes!";
      }
    }
  );

  window.removeEventListener('click', warnAboutLostChanges);

}

4. Carefully adding beforeunload listeners to optimize a web page for bf cache

The beforeunload event is used to display a warning dialog box to inform users whether they want to leave the current page. Chrome and Safari will allow beforeunload event but Firefox will flag the webpage as ineligible for back forward cache.

5. Use rel=”noopener”  in your script to optimize a web page for bf cache

The rel=”noopener” attribute is used to prevent the current page from being able to access the window.opener property. Instead of using a window.postMessage(), you should use rel=”noopener”.

noopener

Conclusion 

Here, we cover the key benefits of using bf cache and the strategies to fix it. The benefits of a website serving from the bf cache are to reduce data usage, improve core web vitals, and a better user experience.

To optimize your web page for bf cache by applying the mentioned strategies like Using cache-control: no-store only for the information-sensitive page, Updating sensitive data after bf cache restore, Using rel=”noopener”  in your script, Avoiding using the unload event, Using rel=”noopener”  in your script.
Now, it’s your turn to apply these powerful strategies to your website and make your website more user-friendly. It will also increase the website’s conversion rate.

How to Avoid an Excessive DOM Size? – 5 Easy Ways to Fix it for WordPress.

Seeing Avoid an Excessive DOM Size on your Google page speed test could be very frustrating, especially if you are not a developer yourself, as it might feel similar to deciphering an ancient text, let alone resolving the issue.

There are many possible ways to Avoid an Excessive DOM Size for WordPress websites, which will be discussed here in an easy-to-understand language so even a non-developer can understand the reasons behind the excessive DOM size issues & and act to resolve them.

Avoid an excessive dom size wordpress

But first, we have to understand what is DOM, or Document Object Model.

DOM is like a translator between web pages and computer programs. It turns the structure, style, and content of a page into objects and nodes that programs can easily work with.

This means programs, especially those written in JavaScript, can change how a webpage looks and behaves by talking to the DOM. It’s like giving JavaScript the power to understand and play with the building blocks of a webpage, including the text and visual elements.

What is DOM Size?

DOM size is the size of the Document Object Mode. DOM size is basically the number of nodes or elements in the DOM tree.

DOM is a representation of data in the form of a tree structure that consists of elements and nodes. Each element related to a node is a child. Every element in the DOM is known as a node which are branches of a tree. Every branch related to the tree is called depth.

Whenever a web page starts loading, the browser generates the DOM of the page. DOM is a programming interface related to XML (Extensible Markup Language) and HTML (Hyper Text Markup Language) documents. 

It defines the analytical structure of a document and the processes by which a document is manipulated and accessed.

With the help of the Document Object Model,  we can simply acquire and manipulate tags, IDs, or HTML elements/tags. It is a method to show the webpage in an organized hierarchical structure.

Through the DOM, JavaScript gains access to both the CSS and HTML of the webpage and also adds behavior to the elements. DOM is an API that interconnects with XML and HTML documents.

In the Document Object Model, documents are structured in a logical formation resembling a tree, representing the hierarchy of nodes such as elements, attributes, and text content. This structure is akin to a forest or grove containing multiple trees.

The DOM consists of different levels or interfaces. One such level is DOM Core, which is utilized to represent the organized structure of a document. Another level is DOM HTML, specifically designed to characterize an HTML document.

Tags play a crucial role as the structural backbone of an HTML document. In the Document Object Model (DOM), each HTML tag and its content are represented as nodes in a hierarchical structure. These nodes, including elements and text content, are accessible through JavaScript, allowing developers to manipulate and change the content of the page dynamically

For example, the ‘document.body’ object in JavaScript refers to the <body> tag in an HTML document. When you run code involving this object, you can manipulate its properties, such as changing the background color. For instance, running code to make the <body> element blue for 3 seconds would involve modifying the CSS properties dynamically using JavaScript.

At this stage, we used style.background to alter the background color of the document.body. Style grants programs to effectively access and operate on the content of style sheets. 

What is the ideal DOM size?

An ideal DOM tree must follow some guidelines,

  1. The ideal DOM size should have less than 1500 nodes total: 
  2.  An ideal DOM should have the highest depth of 32 nodes:
  3.  An Ideal Dom size should not have a parent node with beyond 60 child nodes: 

DOM Structure:

Just assume DOM is a family tree. The family tree has a father, mother, children, siblings, and so on.

DOM TREE

 Likewise, a WordPress or any other website for that matter website has many elements or nodes. Each node has depth or divisions. This organized structure concludes at the last node or child element where no branches are left. 

The content, headings, etc. are an integral part of the large DOM tree, which is required to be effortlessly operated and improved. It is built on the necessity of programming languages such as HTML, CSS, and JavaScript. 

Generally, you have to search for a way to construct DOM nodes whenever it is required and smash them when it is not required. 

Moreover, avoiding an excessive DOM Size in WordPress will positively influence a site’s real-world performance more than just the PSI or Core Web Vitals. As a result, the loading time of the page is reduced and does make it more user-friendly.

What is a DOM element?

A DOM element is something like a DIV, HTML, or BODY element on a page. HTML is needed to build a DOM which is an in-memory presentation of the page.

Effects of Excessive DOM size on PageSpeed Insights score.

To improve the PageSpeed Insights score, it is necessary to reduce the excessive DOM size. An excessive DOM size leads to slower loading time and poor user experience. It would result in failing core web vital test & lower page speed score numbrs.

Why Excessive DOM size in WordPress is a problem?

The larger DOM size presents unnecessary complexities while rendering a web page. The browser is required to implement extra effort to show the webpage on screen. There are some issues with an excessive DOM size when it comes to WordPress that affect the performance of the web page: It also leads to the higher First Contentful Paint.

Excessive DOM Size

 Now, the question is why the effect on page speed of DOM size is a problem. There are multiple ways or problems through which a huge DOM tree can affect or decrease the performance of a page:

  • Network Inefficiency and Lazy Loading: 

Whenever you load the page with too many HTML tags, most of the time the browser needs more resources to render or provide the page. As a result, the page loads slower. It happens because of the bloating of code.

Additionally, it expands unnecessary data costs for the users and decreases the loading time.

  • Increase is page loading time:

 If an expanded and huge DOM tree is blended with complex style rules then it will slow down the page rendering badly. It affects the page’s load time.

An excessive DOM size will automatically decrease the rendering performance. A browser like Google Chrome requires more computation at the time of loading the first page and every time it is required for a user to interconnect with the page.

  • Webpages feel less responsive.

As the browser takes more time to provide and process the content, a huge DOM shows a web page less responsive. This slow responsiveness can badly affect the user’s experience and keep them away from the websites. It also decreases the conversion rate.

 What are the Reasons for the emergence of an excessive DOM size in WordPress?

An excessive DOM Size in WordPress is generated when there are too many HTML tags used on the page or when they are inserted very deeply.

  •  Poorly Coded Plugins or Themes Should Be Avoided

While operating a plugin like a calendar plugin or slider that can create a huge number of DOM nodes.  Likewise, poorly coded themes and templates can critically influence the performance of the website.

  • DOM node reduction by JavaScript

From time to time JavaScript produces a huge number of DOM nodes. For example, a chat widget can develop excessive DOM nodes available on a page’s DOM. 

  • Avoid Page Builders that Produce Bloated HTML

Some Page Builders are required to generate bloated code with a huge number of DOM nodes. Most of the time they are the most important part of the procedure. Themes that are of inferior quality can directly influence an excessive DOM Size in WordPress.

How to avoid excessive Dom size for a new WordPress website?

To avoid an excessive the DOM size for a new website, users are advised to follow the instructions suggested here:

1. Say No to Poorly Coded Themes

If you wish to plan build your website for performance & stay away from an excessive DOM size in WordPress, we suggest to avoid using bloated themes. You can check the performance issue of demo theme and template on Google PSI to see if it’s something worth using on your website.

 2. Remove Irrelevant JS codes

Use browser developer tools to check the performance bottlenecks. This would highlight areas where you can make improvements or remove unnecessary codes.

Also, if you are already not minifying your codes, you should definitely consider it to improve the DOM size.

3. Do Not Use Page Builder without considerations

Page builders are becoming important for website owners because they efficiently drag and drop content accompanied by their pre-built controls. 

But sometimes these plugins produce some supplementary div tags in the HTML that lead to moderate response time.

 Almost all page builders insert too many div tags. To handle this issue, you have to access your HTML and fix it manually. Some page builders take good steps to solve these issues.

For example, Elementor has declared that Elementor 3.0 proceeds with significant DOM improvisation to improve the speed and performance of new websites. You can also use the native WordPress block editor and expand it with block plugins such as Otter Blocks.

4. Stay Away from Complex Codes

Users should try to avoid complex codes to fix the issue of an Excessive DOM Size WordPress. Complicated or dense code, properties, or values can transform the pages unpredictably.

 It also influences the performance and overall experience of the user. Therefore, users should try to keep a distance from the complex codes for their successive and continuous performance of websites.

 How to reduce Dom size it for an existing WordPress website?

An Excessive DOM Size in WordPress leads to the slower rendering of visuals and content and drains a bigger chunk of memory. It also leads to slow interactions, and longer script implementations, influencing the site performance and user experience. 

Avoid an Excessive DOM Size WordPress

 There are multiple ways to fix an excessive DOM size in existing websites, let’s take a look:

  •  Replace the bloated WordPress theme & plugins.

First of all, poorly coded plugins and themes bloat the site’s code and cause DOM to increase. To solve the plugin issue, you have to replace it with a plugin that’s not unnecessary bloated.

Same goes for the themes, avoid bloated multi-purpose themes they might look convenient but most of them come with various options which you might never use but, they bloat the code.

It might not always be possible to change the theme maybe you can look into, we suggest using a performance optimizer RabbitLoader.

  • Do not try to Copy-Paste Text into WYSIWYG Editor:

Almost all WYSIWYG (What You See Is What You Get) editors are not capable enough to clean up the pasted code, specifically when they are copied and pasted from some sources, for instance, Microsoft Word. 

Moreover, it copies the styles as well as text. This issue can be fixed by avoiding directly pasting the text into the editor and removing the bloated text/styling of codes.

 The paste option should be used as the Plain Text Option. An HTML cleaner is perfect for this. Alternatively, you can use Gutenberg in the WYSIWYG editor.

  • Create Multiple Pages Instead of a Single Long Page:

A large single page on the website represents different contents such as blog articles, contact forms, business information, and so on which can lead to excessive DOM size in WordPress or any other CMS.

Instead, splitting a single long page into multiple pages decreases the number of DOM nodes.

  • Implement Infinite Scrolling and lazy loading

A lazy load of the below the first fold of your website is an important way to enhance your initial page rendering, you won’t need to add another plugin on your website if you have RabbitLoader installed, it would take care of the lazy loading.

If its blog page, you can also speed up page rendering by putting restrictions on the highest number of posts on each blog page. Like lazy loading, applying infinite scrolling speeds up the load performance of pages. 

It is needed when the user does not want to scroll the unwanted elements and scrolls the same elements

Final Thoughts

Although you can resolve the excessing DOM size using the tips mentioned above, it’s better to do your planning right & keep this in mind when you first creating your website.

But since it WordPress sometimes you might just can’t do without a specific plugin or theme, for those situation you can use a performance optimizer like RabbitLoader which takes care of all aspects of your performance so you do not need to bloat your website with 10 different performance plugins that conflict with each other.

Optimizing Your Largest Contentful Paint Score: A Comprehensive Guide

In today’s digital age, speed is everything. With millions of websites vying for attention, it’s essential to ensure your website is not only attractive but also fast. Slow-loading websites often result in visitors bouncing off the site, leading to a loss of potential customers. This is where the concept of web performance optimization comes in. Web performance optimization (WPO) is the process of making websites faster and more efficient, making it easier for users to access the content they need. In this blog post, we will discuss one of the most important aspects of WPO – the Largest Contentful Paint (LCP).

What is the Largest Contentful Paint (LCP):

Largest Contentful Paint (LCP) is one of the Core Web Vitals that measure the loading time of a website’s largest content element. In simpler terms, the Largest Contentful Paint measures the time taken by the website to load the largest image or text block visible on the screen. This is important because users tend to focus on the most prominent content when they first land on a website. Therefore, if the largest element of your web page takes a long time to load, it can negatively impact the user experience.

FAQs:

What are Core Web Vitals?

Core Web Vitals is a set of metrics that measure key aspects of a website’s user experience. Google introduced them as part of its effort to improve the quality of the web and help website owners create websites that are fast, user-friendly, and engaging.

The three Core Web Vitals are:

  1. Largest Contentful Paint (LCP) – measures the loading speed of the largest image or block of text visible in the viewport.
  2. First Input Delay (FID) – measures the time it takes for a web page to become interactive, meaning the time between when a user clicks on a button or link and when the page responds to that action.
  3. Total Blocking Time (TBT) – measures the amount of time a web page is unresponsive to user input during loading. This can happen when the page is loading a large number of resources, or if the page’s main thread is busy executing JavaScript code or rendering the page’s layout.

What is FCP?

First Contentful Paint (FCP) is a performance metric used to measure the loading performance of a website. It refers to the time it takes for the browser to render and display the first meaningful content, such as text or images, on the page after a user navigates to it.

Why is the Largest Contentful Paint important?

As mentioned earlier, the Largest Contentful Paint metric is crucial because it determines the loading time of the most prominent content on a web page. The faster the Largest Contentful Paint, the better the user experience, and the higher the chances of retaining visitors on the site. On the other hand, a slow Largest Contentful Paint can lead to visitors abandoning the site, resulting in lost business opportunities.

 A good Largest Contentful Paint score is a key component of a positive page experience, which is a significant ranking factor for Google’s search engine algorithm.

Best 5 Tricks to Minimize Main Thread Work

The main thread handles user interactions, renders the UI, and executes JavaScript code. As web applications become more complex, the main thread can become overloaded, leading to poor performance, sluggishness, and an unresponsive user interface. In this post, we will discuss strategies to Minimize Main Thread Work and improve web application performance.

FAQs:

What is The Main Thread?

The main thread is the central processing unit of an application that handles user interactions, rendering graphics, and executing code. 

Minimize Main Thread Work

Identify Tasks That Can Be Moved Off The Main Thread:

The first strategy to Minimize Main Thread Work in web development is to identify the tasks that can be moved off the main thread. By moving these tasks to a separate thread or queue, the main thread is free to handle user interactions and other critical tasks, resulting in a more responsive and performant web application.

  1. Network Requests:

One of the most common types of tasks that can be moved off the main thread in web development is network requests. Network requests can involve communication between a client and a server, and can be time-consuming, especially if the server is slow to respond. 

In some cases, network requests can block the main thread, making the web application feel sluggish and unresponsive. 

To avoid this, you can use asynchronous programming techniques to perform network requests in the background, while the main thread handles other tasks which helps minimize main thread work.

For example, you can use the fetch API to perform network requests asynchronously in JavaScript. The fetch API allows you to make network requests and return a promise that resolves with the response thus helping to minimize main thread work. 

fetch(‘/api/data’)
  .then(response => response.json())
  .then(data => {
    // handle data asynchronously
  })
  .catch(error => {
    // handle error  });
  1. Heavy computation:

Another type of task that can be moved off the main thread in web development is heavy computation. Heavy computation involves performing complex mathematical calculations or data processing and can be time-consuming, especially for large data sets.

 By moving heavy computation to a separate thread, you can prevent the main thread from being blocked, resulting in a more responsive web application.

One way to move heavy computation off the main thread in web development is to use Web Workers. Web Workers allow you to run JavaScript code in a separate thread, without blocking the main thread. This allows you to perform heavy computation in the background, while the main thread handles other tasks and in the process minimize main thread work.

// Create a new Web Worker
const worker = new Worker(‘worker.js’);

// Send a message to the worker
worker.postMessage({ data });

// Handle messages from the worker
worker.onmessage = function(event) {
  const result = event.data;
  // handle result asynchronously
};

  1. I/O Operations

A third type of task that can be moved off the main thread to minimize the main thread work in web development is I/O operations. I/O operations involve reading or writing data to a file or database and can be time-consuming, especially for large data sets.

 By moving I/O operations to a separate thread, you can prevent the main thread from being blocked thus helping minimize main thread work, resulting in a more responsive web application.

To move I/O operations off the main thread in web development, you can use the File API or IndexedDB API. The File API allows you to read or write data to a file asynchronously, while the IndexedDB API allows you to read or write data to a database asynchronously.

Use Asynchronous Programming Techniques:

The second strategy to minimize main thread work in web development is to use asynchronous programming techniques. By using asynchronous programming, long-running tasks can be executed without blocking the main thread, resulting in a more performant web application.

  1. Promises:

One of the most popular asynchronous programming techniques in web development is Promises. Promises allow you to execute asynchronous code in a non-blocking way, without blocking the main thread. You can create a Promise and use .then() to handle the result when it becomes available, without interrupting the main thread thus helping to Minimize Main Thread Work.

function fetchData() {
  return new Promise((resolve, reject) => {
    fetch(‘/api/data’)
      .then(response => response.json())
      .then(data => resolve(data))
      .catch(error => reject(error));
  });
}

fetchData()
  .then(data => {
    // handle data asynchronously
  })
  .catch(error => {
    // handle error
  });

  1. Async/Await: 

Another popular asynchronous programming technique in web development is Async/Await. Async/Await allows you to write asynchronous code that looks and behaves like synchronous code, making it easier to read and write. 

You can use the async keyword to create an asynchronous function, and the await keyword to wait for the result of a Promise to minimize main thread work.

async function fetchData() {
  try {
    const response = await fetch(‘/api/data’);
    const data = await response.json();
    return data;
  } catch (error) {
    throw new Error(error);
  }
}

(async function() {
  try {
    const data = await fetchData();
    // handle data asynchronously
  } catch (error) {
    // handle error
  }
})();

  1. Callbacks:

Finally, you can also use callbacks to write asynchronous code in web development. Callbacks allow you to execute a function after a long-running task completes, without blocking the main thread which will minimize main thread work. 

You can pass a function as a parameter to an asynchronous function, and the function will be called when the task completes.

function fetchData(callback) {
  fetch(‘/api/data’)
    .then(response => response.json())
    .then(data => callback(data))
    .catch(error => callback(error));
}

fetchData(data => {
  // handle data asynchronously
});

Optimize JavaScript Performance:

The third strategy to minimize main thread work in web development is to optimize JavaScript performance. By writing efficient and optimized JavaScript code, you can reduce the amount of work the main thread has to do, resulting in a more performant web application.

  1. Use JavaScript Libraries

One way to optimize JavaScript performance in web development to minimize main thread work is to use JavaScript libraries that are optimized for performance. For example, you can use jQuery to simplify your JavaScript code and reduce the amount of work the main thread has to do. jQuery provides a simple and efficient API for manipulating the DOM and making AJAX requests, which can help reduce the amount of code you need to write.

Minimize Main Thread Work
  1. Avoid Expensive Operations

Another way to optimize JavaScript performance in web development is to avoid expensive operations. Expensive operations include things like nested loops, recursive functions, and complex mathematical calculations. By avoiding these types of operations, you can reduce the amount of work the main thread has to do thus minimize main thread work, resulting in a more performant web application.

  1. Minimize DOM Manipulation

Finally, you can optimize JavaScript performance in web development by minimizing DOM manipulation. DOM manipulation involves changing the structure or content of the web page and can be expensive in terms of performance. By minimizing DOM manipulation, you can reduce the amount of work the main thread has to do, resulting in a more responsive and performant web application.

Importance of Why to Minimize Main Thread Work for Website Speed:

Minimize main thread work is crucial for improving website speed because the main 

thread is responsible for handling user input and executing JavaScript code. The main thread is single-threaded, which means that if it’s busy executing a long task, such as a large JavaScript file, the website can become unresponsive, resulting in a poor user experience.

When the main thread is busy, the website can’t respond to user input, which can lead to input delay and slow down the website’s loading time. Additionally, long tasks on the main thread can block the rendering of the page and prevent users from seeing content until the script has finished executing.

Improving website speed requires reducing the total blocking time and speeding up the loading time of the page. Minimize Main Thread Work for developers to reduce the amount of time it takes for the page to load and improve the user experience. 

This is especially important for websites that rely on user interaction, as a slow website can discourage users from staying on the site or returning in the future.

To minimize main thread work, developers can use techniques like lazy loading, deferring JavaScript execution, and using web workers to run scripts on multiple threads. 

They can also optimize CSS and JavaScript files by minifying and removing unused code, which can reduce the size of the files and make them load faster. By implementing these techniques, developers can improve website speed and optimize for the core web vitals that Google Pagespeed Insights uses to evaluate website speed, such as speed index, cumulative layout shift, and load time.

Optimizing Main Thread Tasks:

As a web developer, you are constantly striving to create applications that are fast, responsive, and provide a great user experience. One of the most important things you can do to minimize main thread work is to optimize main thread tasks. The main thread handles user interactions, renders the UI, and executes JavaScript code. When the main thread is overworked, it can slow down your web application and create a poor user experience. By optimizing main thread tasks, you can create a more performant web application that responds quickly to user interactions and provides a better user experience thus helping minimize main thread work.

Techniques for Optimizing Main Thread Tasks

There are several techniques you can use to optimize main thread tasks in web development, including:

  1. Reducing the Frequency of Updates: 

One of the most effective ways to optimize main thread tasks is to reduce the frequency of updates. This means reducing the number of times per second that the application updates its user interface. By reducing the frequency of updates, you can decrease the workload on the main thread and create a more responsive web application.

  1. Using More Efficient Algorithms:

 Another way to optimize main thread tasks is to use more efficient algorithms. This means using algorithms that are designed to use fewer resources and execute more quickly. By using more efficient algorithms, you can reduce the workload on the main thread and improve the performance of your web application.

  1. Using Lazy Loading:

 Lazy loading is a technique that allows you to defer the loading of non-critical resources until they are needed. This can help reduce the workload on the main thread and improve the performance of your web application.

Minimize Main Thread Work,lazy loading

Examples of Techniques for Optimizing Main Thread Tasks

  1. Reducing the Frequency of Updates:

 One way to reduce the frequency of updates is to use requestAnimationFrame(). This method schedules a function to run the next time the browser is ready to render a new frame.

 By using requestAnimationFrame(), you can ensure that your updates are synchronized with the browser’s rendering cycle, which can reduce the workload on the main thread and improve the performance of your web application.

  1. Using More Efficient Algorithms:

 One example of using more efficient algorithms is to use a binary search algorithm instead of a linear search algorithm.

 A binary search algorithm is faster and more efficient than a linear search algorithm, as it reduces the number of iterations required to find a particular value. By using more efficient algorithms, you can reduce the workload on the main thread and improve the performance of your web application.

  1. Using Lazy Loading: 

One example of using lazy loading is to defer the loading of images until they are visible on the screen. By using lazy loading, you can reduce the workload on the main thread and improve the performance of your web application.

To further optimize your website speed, you can use techniques like minifying CSS and using smaller JS payloads. Minifying CSS removes unused CSS and reduces the file size, making it easier and faster to load. Using smaller JS payloads reduces the loading time and improves the loading speed of your website.

Conclusion

Minimize Main Thread Work is essential for creating a performant web application that provides a great user experience. By reducing the frequency of updates, using more efficient algorithms, and using lazy loading, you can optimize main thread tasks and improve the performance of your web application.

To recap, some of the strategies we discussed in this post to minimize main thread work include using requestAnimationFrame() to reduce the frequency of updates, using more efficient algorithms such as binary search, and using lazy loading to defer the loading of non-critical resources until they are needed.

We encourage you to try these strategies in your own web development projects to see how they can improve the performance of your applications. By optimizing main thread tasks which helps minimize main thread work, you can create a faster, more responsive web application that provides a better user experience.

A Guide to Resource Loading and its Importance in Web Development

Resource Loading is a crucial aspect of web development that plays a significant role in the user experience, search engine optimizations, and cross-device compatibility of a website. It refers to the process of fetching and downloading the various elements and resources of a website, such as images, videos, stylesheets, and scripts, from a server to the user’s browser. 

In this blog post, we will delve into the world of Resource Loading and its significance in web development. From explaining what Resource Loading is and how it works to exploring the importance of Resource Loading for user experience, SEO, and cross-device compatibility, this post will provide you with an overview of everything you need to know about Resource Loading. Additionally, we will cover best practices for Resource Loading, common challenges, and solutions to ensure that your website is optimized and runs smoothly.

What is Resource Loading? 

Resource Loading refers to the process of fetching and downloading resources from a server to the user’s browser. The resources loaded on a website can include images, videos, stylesheets, and scripts, among others. These resources are then used to render the website for the user. 

There are two types of resources that can be loaded on a website: blocking and Non-blocking resources. Blocking resources are resources that must be loaded before the page can be displayed, such as stylesheets. Non-blocking resources are resources that can be loaded asynchronously, in parallel with the main page, such as images and scripts. 

The loading process begins when the user requests a page by entering its URL in the browser. The browser then sends a request to the server, which sends back the HTML file, along with any other resources that the HTML file calls for. The browser then parses the HTML file and requests any additional resources that the HTML file calls for, such as images, stylesheets, and scripts. 

Once the resources are fetched and loaded, the browser can display the complete webpage to the user. The loading process can take anywhere from a few milliseconds to several seconds, depending on the style and complexity of the website, as well as the user’s internet connection speed.

Measuring Resource Loading: 

Resource Loading can be measured in several ways: 

  1. Page Load Time: 

Page load time is one of the most common metrics used to measure Resource Loading. This metric measures the time it takes for a page to fully load, including all of its resources, such as images, stylesheets, scripts, and fonts. 

Page load time is an important metric as it provides a direct measure of the user experience, as users expect pages to load quickly and efficiently.

  1. Time to First Byte(TTFB): 

Time to first byte (TTFB) is another metric that measures Resource Loading. TTFB measures the time it takes for the first byte of data to be received from the server after a request has been made. 

This metric provides insight into the performance of the server and the efficiency of the resource-loading process.

  1. Page Weight: 

Page weight is a metric that measures the total size of a page, including all of its resources. Page weight is an important metric as it directly affects the page load time, with larger pages taking longer to load.

 By optimizing the page weight, you can reduce the page load time and improve the user experience.

  1. Resource Load Time:

Resource load time is a metric that measures the time it takes for individual resources to load. This metric provides insight into the performance of specific resources that help identify any resource that may be slowing down the page.

  1. Performance Tools:

There are various performance tools available, such as google page speed insights, google lighthouse and GTmetrix, that can be used to measure Resource Loading. These tools provide a comprehensive analysis of Resource Loading, including metrics such as page load time, TTFB, page weight, and resource load time, as well as recommendations for optimizing Resource Loading.

Best practices for Resource Loading:

To ensure that your website is optimized for Resource Loading, it is important to follow best practices. Some of the best practices include:

  1. Minimizing HTTP Requests:

One of the most effective ways to optimize Resource Loading is to minimize the number of HTTP requests that are made. Each HTTP request adds to the loading time of a page, so reducing the number of requests can significantly improve page speed. To minimize HTTP requests, you can use CSS sprites, combine multiple stylesheets into one, and optimize images by reducing their size and using the appropriate format.

  1. Compression and Minification:

Compression and minification are techniques used to reduce the size of resources, such as stylesheets and scripts, which can result in faster loading times. Compression involves reducing the size of files by removing redundant information, while minification involves removing unnecessary whitespace, comments, and other elements from the code.

  1. Caching and Preloading:

Caching involves storing frequently used resources on the user’s device so that they do not have to be reloaded every time the page is visited. Preloading involves loading resources in the background before they are actually needed so that they are available instantly when required. Both caching and preloading can significantly improve the speed of Resource Loading.

  1. Async and Defer Attributes:

The async and defer attributes can be used to control the loading of resources on a page. The async attribute specifies that a resource should be loaded asynchronously, allowing the browser to continue rendering the page while the resources are being loaded. The defer attribute specifies that a resource should be loaded only after the page has finished parsing, ensuring that the resource does not block the rendering of the page. 

  1. Lazy Loading:

Lazy loading is a technique in which resources are loaded only when they are needed, rather than loading all resources at once. This can significantly improve the loading speed of a page, especially for large and complex websites. Lazy loading can be implemented using JavaScript, allowing resources to be loaded only when they come into view, or as they are requested by the user.

  1. Image Optimization:

Image optimization is another important aspect of Resource Loading. Large and unoptimized images can significantly slow down the loading speed of a page, so it is important to optimize images by reducing their size, using the appropriate format for example JPEG for photos, PNG for graphics, and compressing them if necessary.

Implementing best practices for Resource Loading is essential for optimizing the performance of your website and providing a better user experience. By reducing the number of requests, reducing the number of requests, minification, compression, etc.

While these optimizations can be done manually, they can be time-consuming and challenging to implement and maintain. Fortunately, there are tools like RabbitLoader available that can automate many of these optimizations for you, saving you time and effort while ensuring that your website is optimized for performance and provides the best possible user experience.

FAQs:

What are async and defer?

Async and defer are attributes that can be added to script tags in HTML to control the loading and execution of JavaScript files.

Async allows the script to be loaded and executed asynchronously, meaning that it does not block the loading of other resources or the rendering of the page. This can result in faster load times.

Defer is similar to async in that it allows the script to be loaded and executed asynchronously however unlike async, the defer attribute guarantees that the scripts marked as defer will be executed in the order in which they appear in the HTML.

Common Challenges and Solutions:

Despite following best practices for Resource Loading, there are still some common challenges that can arise, some of these challenges include:

  1. High HTTP Request Count:

One of the most common challenges in Resource Loading is having a high number of HTTP requests. This can result in a slow-loading website and poor user experience, so it is important to minimize the number of requests by combining resources and optimizing images.

5 Easy Ways To Speed-Up Your Website By Improving First Contentful Paint.

A good First Contentful Paint for a website is crucial for a positive user experience. A slow website can cause visitors to leave quickly, increasing bounce rates.

One of the ways to measure website speed is by the First Contentful Paint (FCP). Lower FCP time means better user experience which can in turn improve search engine optimization making the websites rank better on Google search.

In this guide, we will explain what FCP is, why is it important, then show you how to improve it for a better user experience. 

What is First Contentful Paint (FCP):

First Contentful Paint (FCP) is a performance metric used to measure the loading performance of a website. It refers to the time it takes for the browser to render and display the first meaningful content, such as text or images, on the page after a user navigates to it.

 The lower the FCP time the better the user experience and the better the SEO rankings.

Below you can view the image of the First Contentful Paint score of a portfolio website when viewed on a desktop VS when viewed on a mobile phone

FAQs:

Why is the FCP time different for mobile and desktops?

The FCP time can differ between desktop and mobile devices for several reasons like network condition, screen size, and resolution, device and browser performance, server performance, etc 

Hence it is important to consider the First Contentful Paint for both desktop and mobile devices to ensure a positive user experience on all platforms.

If the First Contentful Paint measures the time to load the first content on the page then what measures other contents on the page?

There are various other metrics that determine this one of them being the largest contentful paint (LCP) that measures the loading performance of the largest content on the page. 

It calculates the time from when the page loads to when the largest element is rendered, similarly there are various other metrics that help improve user experience.

Why is First Contentful Paint Important:

First Contentful Paint (FCP) is a key performance indicator for websites, as it measures the time taken for the first visible content to appear on the user’s screen, there are tools available that you can use to measure the FCP time of your website like a Lighthouse, Google page speed developed by Google.

In addition to improving the user experience, a low FCP time can also have a positive impact on search engine optimization. Google and other search engines use website speed as one of the ranking factors and a fast FCP time means a higher rank and improved visibility of the website.

Search engines aim to provide users with relevant and high-quality results, and user experience is a significant factor in determining the relevance and quality of a website. A slow-loading website can discourage users from staying on the page, and search engines may interpret this as a sign of low quality.

By lowering the FCP time website owners can ensure that their site provides a positive user experience, which can help to improve their search engine ranking and visibility.

FAQs:

How Much of an Impact will Optimize FCP Have on my SEO Rankings?

FCP is part of Google’s core web vitals initiative and will influence Google’s SERP (search engine result pages) rankings as a result its critical for websites owners to understand how to achieve excellent FCP scores 

What is a Good FCP Score? 

To provide a good user experience, sites should strive to have a First Contentful Paint of 1.8 seconds or less. To ensure you’re hitting this target for most of your users, a good threshold to measure is the 75th percentile of page loads, segmented across mobile and desktop devices.

How to Optimize First Contentful Paint:

To improve FCP and website speed it’s important to follow best practices and implement optimizations here are some tips for optimizing FCP and improving the user experience:

Minimize JavaScript :

Excessive JavaScript can slow down website loading including First Contentful Paint. Mining JavaScript usage by embedding scripts asynchronously and reducing the amount of code used.

As if the JavaScript is render-blocking (not asynchronous) the browser must compile parse and evaluate before rendering the rest of the page

Whilst even being asynchronous the code would compete with other resources for higher bandwidth resulting in wastage of data which is a bad thing for mobile users not having unlimited data plans.

In addition to this, libraries like jQuery can be used to minimize and optimize JavaScript. 

Minimize javascript

FAQs:

What does asynchronous mean in JavaScript? Good

Asynchronous in JavaScript means that a task can run in the background, without blocking the rest of the code from executing. This allows for more efficient use of resources and a smoother user experience. For example, when loading data from a server, asynchronous code would allow the rest of the page to continue functioning while the data is being retrieved, instead of freezing until the data has arrived 

What is jQuery:

jQuery is a lightweight JavaScript library its purpose is to make it much easier to use JavaScript on your website. JavaScript takes a lot of common tasks that require many lines of JavaScript code and wraps them into methods that you can call with a single line of code.

Reduce page redirects : 

Page redirects are an additional HTTP request that adds latency and increases the time it takes for a page to load. By reducing the number of redirects you can improve FCP and overall page load speed 

Some of the ways you can reduce redirects are :

  1. Avoid redirecting to external pages: redirecting to external sites can significantly slow down your FCP, avoid redirecting to external sites whenever possible and instead link the target page directly 
  1.  Use permanent redirects (301) instead of temporary (302): permanent redirects are cached by browsers reducing the number of requests needed to load a page whereas temporary redirects are not cached and need an additional request increasing latency and slowing down First Contentful Paint.

To perform this optimization manually you can do redirect mapping and make sure that all internal links are pointing to the correct pages.

With RabbitLoader, you can easily manage redirects and eliminate unnecessary redirects to improve website speeds and lower First Contentful Paint times.

Utilize a CDN (Content Delivery Network) :

CDNs are a network of servers distributed globally that cache and serve website content to users based on their geographical location. Utilizing a CDN can help improve First Contentful Paint by reducing the distance data has to travel from the server to the user’s device. 

It increases the speed of content delivery, improves user experience, increases scalability, and enhances security 

To do this manually you can set up and configure a CDN for your website. With RabbitLoader, you can leverage the power of a global CDN network to enhance website speed and First Contentful Paint without the need for manual configuration

FAQs:

What is a CDN?

A Content Delivery Network is a large network of servers located in different geographical locations around the world. The purpose of a CDN is to provide fast and efficient delivery of website content, such as images, videos, and other media, to users, this is done by reducing the distance that the data has to travel from the server to the user’s device, which in turn reduces the amount of time it takes for the content to load.

Reduce your DOM size :

The DOM is a tree-like structure that represents the elements and content on a web page the larger the DOM the more data needs to be processed by the browser leading to slower website speed and slower FCP 

Methods to reduce DOM size :

  1. Avoid nested elements: nested elements increase the size of the page DOM and slow down your website consider flattening the structure of the DOM to reduce its size 
  2. Use CSS instead of HTML: using CSS to style elements instead of putting the style elements in HTML can reduce the size of the DOM and improve website speed 
  3. Minimize the number of elements: By minimizing the number number of elements on the page will reduce the DOM size and improve the First Contentful Paint.

FAQs : 

What is DOM?

DOM stands for Document Object Model, it is a tree-like structure that represents the elements and contents on a webpage the larger the DOM the more data needs to be processed by the browser leading to slower website speeds and higher First Contentful Paint times.

What are Nested Elements?

Nested elements are HTML elements that are contained inside other HTML elements. For example, you might have a “div” element that might have several “p” elements, each of which contains the text. The “p” elements are called nested elements inside of the “div” elements.

In simple language, it’s like having a box within a box. The inner box is contained in the outer box and is a part of it. Similarly, nested elements are elements within other elements and are considered a part of the outer elements

Eliminate Render-Blocking Resources :

Render-Blocking Resources are scripts and stylesheets that block render till the page loads and do not display it until they have loaded, this can significantly slow down First Contentful Paint and lead to poor performance and bad user experience 

Some methods to Eliminate Render-Blocking Resources are :

  1.  Minify your JavaScript and CSS: This means removing all extra whitespace and unnecessary comments in the code.
  1. Generate critical CSS and inline it: inlining critical styles into HTML and CSS documents can help reduce the number of Render-Blocking Resources and improve First Contentful Paint.
  1. Use resource prioritization: prioritize the loading of resources based on their importance on the page. For example load images and videos before the scripts and stylesheets 

You can optimize your CSS and JS files by implementing various techniques 

With RabbitLoader you can eliminate Render-Blocking Resources automatically to improve website speed and lower First Contentful Paint time.

FAQs: 

What are Render-Blocking Resources?

Render-Blocking Resources are scripts and stylesheets that block the render process until they have loaded, these files block or slow down the display of the page content as the browser must wait until these files have loaded, which can significantly slow down the First Contentful Paint time.

What does inlining critical CSS styles into HTML mean?

Inlining critical style into HTML and CSS means taking the essential and the most important styles that are needed to render the content of a web page and adding them directly into the HTML code of the page, instead of linking to an external stylesheet. This reduces the number of HTTP requests and improves the page load time for the initial view

Use a faster server :

A fast and reliable server can quickly improve the website speed and first contentful time by reducing the time it takes to send and receive data between the server and users Browser 

FAQs:

What is a server?

A server is a computer that provides resources or services to other computers, in this context a server is used to server and store web pages for users who request them through their web browsers.

When a user requests a web page, the request is sent to the server hosting the website. The server then sends back the requested web page and its files such as images stylesheets etc, the browser then render the page for the user to view.

Enable lazy loading : 

Lazy loading is a technique that only loads that are in the viewport, reducing the amount of data downloaded and speeding up the First Contentful Paint. By enabling lazy loading visitors will only have to download the images that they need reducing the risk of slow First Contentful Paint time.

Enabling lazy loading not only reduces data usage but also enhances search engine optimization.

You can implement lazy loading using JavaScript files manually RabbitLoader can automatically enable lazy loading.

FAQs:

What is a viewport?

Viewport is the visible area of the web page that is displayed on a user’s display. It defines the size and scale of the web pages dom content and can be manipulated through CSS and JavaScript to create responsive designs that look good on any screen size. 

The viewport is an essential aspect of web design, as it helps ensure that web pages are optimized for different devices, including desktops, laptops, mobile phones, etc.

Monitor performance :

Regular monitoring is crucial for maintaining fast content and optimizing the FCP. Use analytics, real user monitoring, and performance reports to monitor First Contentful Paint and identify any issues that need to be addressed.
