If you have tried disminutir the load times of your website, it is also possible that you have been recommended to minimize JavaScript and CSS files, programming languages front-end responsible for making your website interactive (JS), visually appealing (CSS).

But for effective use, the programs must be small enough to load quickly, that is why the minification of code is a component so integral to the optimization of the front-end.

Add-ons

Add-ons add functionality and value-added to the desktop software, mobile applications and devices IoT; however, they may decrease the speed of the web pages to increase the load times or creating bottlenecks. Therefore, in order to maintain optimum performance, it is vital that the add-ons are kept up to date and minimize its use for optimal results.

Many of the same techniques used to increase the speed of the web site also reduce the time of loading of the add-ons, such as caching, minification of the code, the use of CRC and the optimization of the configuration of the server. When choosing a hosting provider that can support high-performing sites.

The plugin Autoptimize WordPress functions provides minification effective to improve the loading time of a site, the score of PageSpeed Insights and the score of Core Web Vitals. With its wide range of tools (image optimization, compression, JS/CSS, deferred rendering premature JavaScript files that are blocking the rendering, file merging, lazy loading of images), Autoptimize can help to significantly reduce the loading time while improving the scores of Core Web Vitals and protects against the direct links that prevent other websites from using its resources to publish their own content; autoptimize can also help to reduce the charging time.

One of the major factors behind the load times slow web sites is the size of large files, which take longer to be downloaded and processed. One way to reduce this delay is to minimize JavaScript and CSS files by removing characters, comments and unnecessary whitespace and shortening the names of the variables; an alternative approach would be to use the asynchronous loading in the scripts and style sheets are loaded after the HTML page has loaded completely.

Finally, it is essential to use a theme fast loading and optimize the performance of server. In essence, the faster it loads your website, the greater your chances of retention and conversion between the visitors, especially the sites B2C where any delay could cost you sales and generate dissatisfaction in the customer. 

The CDN, add-ins for storage in a cache or plug-ins that can compress files, can help to optimise the performance of the server in this sense and to minimize load times by compressing and minimizing the archives as much as possible; all of these strategies can speed up the web sites significantly increase conversions, and improve SEO.

Minificadores command line

JavaScript is a programming language oriented text that allows web sites to create interactivity for its users. It is used along with HTML and CSS to structure web sites; however, stands out for being visible directly to the browser, something that other languages do not do so often. JavaScript plays an integral role in the improvement of the performance and the success of the website.

Minimize JavaScript files is key for the proper functioning of any website, as this process reduces your code to eliminate points and commas, blanks, and comments that slow load times or the access time of the user. In addition, this reduces the HTTP requests made to your server and decreases the bandwidth consumption on their web site.

Developers now have a variety of tools minification of JavaScript at your disposal, being the most prominent UglifyJS, babel-minify (formerly Babili) and Terser. These tools allow web developers to remove unneeded characters without altering its functionality, and compress files to reduce storage costs and bandwidth.

In addition to minimising the files JS, optimize the load times for the server-side of your website can also greatly increase your time to first byte (TTFB). A CDN or optimize the settings of the server are excellent ways of doing this.

One way to speed up your website is to use the cached versions of JS and CSS files; this is possible if your hosting service provides CDN service like Kinsta; Using CDN can reduce download times, and load up to 50%!

To increase the speed of your web site, it may be advantageous to employ a content delivery network with global reach. This will allow customers easy access to their pages in any part of the world and at the same time, will reduce the load times of each page. 

The best CDN present times of activity elevated and are easy to set up, in addition, provide SSL certificates free as additional protection against malware and hacks. These can be used to automatically minimize files, JS/CSS, and to further accelerate load times.

CDN as an option to improve loading times.

To minimize the size of the files is the first step towards the optimization of the files. The minification, that removes whitespace and comments from CSS files, and JavaScript without affecting the functionality, in addition to the use of names of functions and variables shorter, you can significantly reduce the file size without compromising functionality. The minification also speeds up web pages, and uses less bandwidth.

Increase the speed of the page by reducing HTTP requests. One approach is to put style sheets and scripts in external files so that browsers can store them in the cache, reducing unnecessary requests from browsers. Another strategy is the compression, which reduces the file size by removing spaces and additional characters. 

Finally, combine and minimize JavaScript and CSS files it can also help to improve the performance; this approach can also be combined with the movement of the styles to the section head> of HTML documents to further speed the loading time of the page.

The CDN can help to improve the loading times of the website to provide users with a better overall experience. For example, when you watch videos on YouTube, the CDN will look on their servers to deliver the video files according to your location, similar to how the traffic on the roads, the request to reroute to avoid the congestion by taking shorter paths and thus to secure user experiences higher.

The CDN use content distribution networks (CDN) to store cached versions of web content in multiple geographical locations (known as points of presence, or POP) all over the world and when someone from New York tries to access a page that is hosted in London, comes across servers, CDN, located close to provide a fast service, it helps significantly to the speed and performance of web sites. This is how the CDN become so effective improve the speed and performance of a web site.

Tools

The tools of minification can help to improve the loading time of the page regardless of whether you use or not a WordPress theme pre-engineered, create sites in an editor or use other built-in templates, since they eliminate white spaces, comments, delimiters, and variables of long names of the source code, in addition to merge files, reconstructing and reduce their size, which helps make web sites faster and easier to use. 

Some tools even have advanced features like lazy loading of JavaScript online tests delayed; it Precargue labels custom JavaScript and turn off caching completely!

The minification offers numerous advantages, but its management may be difficult. Remove comments and white spaces of the files can make it difficult to read or debug, breaking other complex scripts that depend on them. Therefore, it is strongly recommended to perform this task along with other techniques to improve the performance.

The tools of minification usually divided into two categories: manual and automated. The programs manuals consist of interfaces on-line that allow users to paste code without formatting directly in an interface and then generate versions minimized automatically; a popular example of this is the version in command line CSSnano, that offers maximum flexibility; other programs are applications IDE or GUI functions with minification native, as a Koala or Prepros, which also feature functions of minification native.

Grunt and Gulp are automated tools designed to automate tasks and at the same time offer flexible options of customization. Grunt can be integrated with other tools, CI/CD and Jenkins, while Gulp provides multiple add-ons that help to minimize files HTML, CSS and JavaScript.

There are several approaches available in jQuery that allow the minification of code, and UglifyJS offers a solution; compresses and minimizes JavaScript without affecting its functionality, however, this tool is not compatible with the syntax SS6. Terser, a fork alternative of Uglify-ES that is compatible with your CLI and API, it could also be an option as an alternative way to minimize the code.

Close Compiler is another effective tool to minimize the size of the JavaScript files, as it offers minification of HTML files and JavaScript, as well as optimization to increase the speed of execution. Available as a command-line application or web application, and regularly updated for maximum reliability, Closure Compiler provides another effective solution to reduce the size of the files of scripts in JavaScript.
