Minifying your code


We now have something we may want to share with the world, something that we may even want to deploy to one of our own applications. As our extension may be unnecessarily large now, it might take longer for slower devices to run our application. A technique that is often used to handle this issue is minification. This recipe looks at how we can reduce the size of our extension using UglifyJS.

Getting ready

Install UglifyJS (http://lisperator.net/uglifyjs/). If you already have NodeJS and npm set up, you can just install it as follows:

npm install uglify-js

Note

Depending on your system, it may be necessary to install UglifyJS globally. If this is the case, you can install UglifyJS globally with the following command:

npm install uglify-js -g

How to do it...

  1. Minify our extension using the following code:

    uglifyjs myExtension.js -o myExtension.min.js

How it works...

UglifyJS is a JavaScript parser, compressor, and beautifier. This means that is can take a JavaScript file as an input...
