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.
#Minify js file code#
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.
We can then minify the file by using the following: node r.js -o name=myfile out= baseUrl=. Here it defines a sub task name, applib with the value of a JavaScript object defining the source files and the destination file. Revert your changes any time You can revert your minified files to make edits or fixes before minifying them again. No dev experience required Anybody can minify their files with the press of a button. We should see our files, r.js and myfile.js, in this folder by using the command: ls Minify your files with ease Reduce the size of your JavaScript, Liquid, and CSS asset files for improved site performance.
This opens up a new Terminal window (I’m on a Mac). With the container running, click the icon for the CLI. Under Volumes, set Host Path as ~Documents/MyFolder (the folder we have created in Step 1). ~Documents/MyFolder and put both r.js and myfile.js in this folder.Īssuming we already have pulled the latest Docker image, click Run on the node image under Docker Desktop.
#Minify js file install#
I did not install requirejs using npm as there is a simpler method for my use case - just getting the r.js file, as listed here, under Latest Release.įor convention, I’m assuming the name of the file we want to minify is myfile.js.Ĭreate a folder, e.g. I’m using RequireJS in Node, and running NodeJS on Docker. And RequireJS has an optimizer that we can use. Sometimes I get paranoid and instead of pasting stuff onto someone else’s page, I prefer to use something that’s not on a server. This is just a small subset from the the available tools, but these are the ones I use most often:
This article does not talk about that, but an example of an obfuscator can be found here). There is also an added benefit: minifying the Javascript files makes them less readable for the laymen, and hence offers some protection against copycats (with only minification this can be reverse engineered and we will need an obfuscator instead. One of the ways to make our websites load faster is to minify our Javascript files.
