What is uglify-es?

The uglify-es npm package is a JavaScript parser, minifier, compressor, and beautifier toolkit for ES6+ (ECMAScript 2015 and later). It is used to reduce the size of JavaScript files by removing unnecessary characters and optimizing the code.

What are uglify-es's main functionalities?

Minification

This feature allows you to minify JavaScript code, reducing its size by removing whitespace, comments, and other non-essential characters.

const UglifyJS = require('uglify-es');
const code = 'function add(first, second) { return first + second; }';
const result = UglifyJS.minify(code);
console.log(result.code);

Compression

This feature compresses JavaScript code by applying various optimizations, such as removing dead code and inlining functions, to make the code more efficient.

const UglifyJS = require('uglify-es');
const code = 'function add(first, second) { return first + second; }';
const result = UglifyJS.minify(code, { compress: true });
console.log(result.code);

Mangle

This feature renames variables and function names to shorter names, reducing the overall size of the code.

const UglifyJS = require('uglify-es');
const code = 'function add(first, second) { return first + second; }';
const result = UglifyJS.minify(code, { mangle: true });
console.log(result.code);

Beautification

This feature formats the JavaScript code to be more readable, which is useful for debugging and code reviews.

const UglifyJS = require('uglify-es');
const code = 'function add(first, second) { return first + second; }';
const result = UglifyJS.minify(code, { output: { beautify: true } });
console.log(result.code);
