3. JavaScript Optimization

JavaScript Optimization
JavaScript Optimization by W3speedster is the process of minifying JS, lazy loading JS, preloading custom JavaScript, and much more. Here is the step-by-step process to do it:

  • Enable JavaScript Optimization:

The first step towards JS optimization is to enable minification.

Minification is the process of minimizing code and script files in your web pages. It’s one of the main methods used to reduce load times and bandwidth usage on WordPress websites.

  • Exclude JavaScript Tags from Combine:

W3Speedster allows you to exclude JavaScript files of the pages you do not wish to Lazy Load and JS Minify by putting JS URL (eg: xyz.js) in the pertaining section. You can leave defer box unchecked.

  • Preload Custom JavaScript:

Apart from deferring, you also get an option to choose files to preload by adding custom javascript. The plugin allows you to preload any JavaScript you wish by adding in this section without a script tag. However, this feature can only benefit developers who have a thorough knowledge of adding customized JS. 

Preloading ensures the media file to be loaded when the page loads.

Don’t forget to enable Load as a file and defer once you enter the custom JavaScript. With this, JavaScript files that are allowed to load with page loading will get lazy-loaded.

Preload Custom JavaScript:

  • Exclude inline JavaScript from combine:

Enter the script or part of the script url to exclude it from optimization. With recommended settings, the plugin will automatically fill the section with certain files.

Moreover, you can also add the “defer” attribute to the excluded files with a space. For eg. “jquery.min.js defer”. If you wish to not minify it then add “full” after a space. For eg. “jquery.min.js full”.

  • Force Lazy Load JavaSript:

Put the specific word from the inline script tag, script URL, or part of the script URL to Force Lazy Load JavaScript which takes a lot of time to load (Eg. Facebook/Instagram).

  • Load Combined JavaScript:

W3speedster plugin allows you to load minified and combined js on page load or after page load. It is recommended to use after page load to score better on google page speed insights or other speed tools. This will load all your minified javascript once the page loading will be completely done to make your web page load faster.

Be careful while enabling this option as it can also break your site. For best practice, use load combined JS in combination with ‘exclude javascript from optimization’ to keep a quality user experience when the page loads.

Moreover, the plugin has various hooks which can help you in customizing javascript minification and lazy loading features. Checkout the plugin documentation for more info.

Load Combined JavaScript:

  • Delay Internal Javascript Tags:

The next step is the delay of internal javascript tags by a few seconds. This option can be used when ‘after page load’ is selected in ‘Load combined JavaScript’. Enter the seconds in the box you wish to delay the load of combined and minified javascript. It is recommended to delay script tags by 10 seconds.

  • Exclude Page from JavaScript Optimization:

With W3Speedster Plugin, you can easily exclude pages from JS Minification which you do not wish to Lazy Load and JS Minify by putting page script URL or part of the script URL.

Exclude Page from JavaScript Optimization:
Please enter each script url or part of the script url in a separate line.

  • Custom JavaScript

You also have an option to add custom JavaScript in this section.

Save all the changes and updates. Remember, Custom JavaScript will load after all internal minified javascript is loaded.
