@types/uglify-js

What is @types/uglify-js?

@types/uglify-js provides TypeScript type definitions for the UglifyJS JavaScript minification tool. UglifyJS is used to compress and minify JavaScript files, making them smaller and faster to load.

What are @types/uglify-js's main functionalities?

Minify JavaScript Code

This feature allows you to minify JavaScript code, reducing its size and improving load times. The code sample demonstrates how to use UglifyJS to minify a simple JavaScript function.

const UglifyJS = require('uglify-js');
const code = 'function add(a, b) { return a + b; }';
const result = UglifyJS.minify(code);
console.log(result.code);

Compress JavaScript Code

This feature enables compression of JavaScript code, which can further reduce the size of the output. The code sample shows how to use the compress option to achieve this.

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

Mangle Variable Names

This feature allows you to mangle variable names, making the code harder to read and reverse-engineer. The code sample demonstrates how to use the mangle option to obfuscate variable names.

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

Other packages similar to @types/uglify-js

terser

Terser is a JavaScript parser, mangler, and compressor toolkit for ES6+. It is a fork of UglifyJS and offers similar functionalities with better support for modern JavaScript syntax. Terser is often preferred for projects using ES6 and beyond.

babel-minify

Babel Minify (also known as babel-preset-minify) is a minifier based on the Babel toolchain. It provides minification and compression for JavaScript code, with a focus on compatibility with Babel's ecosystem. It is a good choice for projects already using Babel for transpilation.

google-closure-compiler

Google Closure Compiler is a JavaScript optimizer that compiles JavaScript into a more efficient form. It offers advanced optimizations and can handle large codebases. It is more complex to set up compared to UglifyJS but can provide better optimization results.
