Gzipping works by finding the repetitive strings and replacing them with pointers to the first instance of the string. In fact, people often use the term “gzipping” as a substitute for compression. The most popular compression tool is gzip.
#Minify js file code
While minification removes unnecessary data from a file, compression rewrites the files’ binary code and encodes the information using fewer bits than the original. However, there’s a fundamental difference between the two. Both techniques essentially provide the same benefit, i.e., making files smaller. People often confuse minification and compression, which is understandable. The Difference Between Minification and Compression (Gzipping) Lots of CDN providers also automatically minify files on their servers. Most JavaScript libraries provide minified versions of their files by default. That’s why minification has become an industry standard over the last few years. But when you apply the process to large code files, the savings are significant. In this example, the actual size difference between the regular and minified version is tiny. When we run it through a CSS minifier, the same code looks like this: (Of course, they also help developers write and review code, but browsers don’t care about that.)įor example, here’s how an unminified CSS files looks: In that sense, all they do is bloat code files. Minification is the process of removing unnecessary elements from your website’s code without affecting its performance.Ī few examples of unnecessary elements are:īrowsers don’t need these to render the page. What is HTML, CSS and JavaScript Minification? If you aren’t interested in the “why” behind these techniques, skip ahead to the "Tools for HTML, CSS and JavaScript Minification section".Īnd for the easiest way to optimize your website’s code, go to "Automated Minification and Compression with NitroPack" įor now, let’s dive a bit deeper into minification. Good thing is, there are lots of tools that can help you with that. And while different, the smart move is getting them in one go.
Minification - removing unnecessary parts like whitespace and comments from the code Ĭompression - applying algorithms to rewrite the files’ binary code, using fewer bits than the original.īoth are low effort, high reward optimizations. You can make code files lighter by applying two techniques: Please make sure that these unminify tools for JavaScript will not change the name of the variable back to their original names.Reducing HTML, CSS and JavaScript file size is a crucial part speeding up your website. You can click on that icon, and then it will convert or unminify your file to how it was previously, as shown in the following. function incrementCounter() icon is known as pretty print. The below code is the original source code that programmers write before the minification process. Let’s take an example to understand how we can unminify JavaScript files. So, to overcome this issue, we have to unminify the minified JavaScript files. The only drawback of this minification process is that it’s really difficult to edit or modify such files if you want to work on them later in the future. This process is essential since it helps us load the web pages faster, reducing the page load times. The files after the minification process are known as minified files. Minification is the process of compressing a file by removing unwanted things, including unnecessary code, spaces, and comments, reducing the length of variable names to single characters, which reduces the file size.
