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• It uses the up-to-date google-closure-compiler package on npm, rather than the outdated google-closure-compiler-js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

npm install rollup-plugin-closure-compile

Usage

import closureCompile from 'closure-compiler-rollup'

// In Rollup config:

    })
]
