rollup-plugin-closure-compile

Rollup plugin that lets you compile your code with Google Closure Compiler

Why this plugin?

Google Closure Compiler is the best JS minifier
It uses the up-to-date google-closure-compiler package on npm, rather than the outdated google-closure-compiler-js
It doesn't require you to have Java installed
Simple setup and use

Caveats

Yes, this plugin will run slower than Uglify or Terser, but it will typically produce a smaller code size. You decide if it's worth it.

Install

With Yarn:

yarn add rollup-plugin-closure-compile

With npm:

npm install rollup-plugin-closure-compile

Usage

import closureCompile from 'rollup-plugin-closure-compile'

// In Rollup config:

    closureCompile({

    })
]
