Table of Contents

(TOC generated by verb using markdown-toc)


This project requires Node.js >=10.13 (see Support & Release Policy). Install it using yarn or npm.
We highly recommend to use Yarn when you think to contribute to this project.

$ yarn add babel-preset-optimise


module.exports = {
  presets: ['babel-preset-optimise'],

Note: initially it was meant to be called babel-preset-optimize, but the package was squatted before I get able to push all this things. Born in discussion with @JounQin in 1stG/configs issue#8.

What it includes?

It uses the most recent and modern preset by the Babel Team - @babel/preset-modules, plus optionally the TypeScript and the React presets. It also includes a several optimization plugins from the Babel Minify project which are very well curated for best and small output.


Generated using jest-runner-docs.


Be aware that when you use minifyBuiltins: true you MAY get a bigger output, but that's not always guaranteed, just try for your case.

If you want to use JSX (React) pass options.jsx: true. If you want to use JSX (React) + TypeScript pass both { jsx: true, typescript: true }. If you wan to use Preact + TypeScript, { jsx: { pragma: 'h' }, typescript: true }, if options.jsx is an object, it is directly passed to preset-react.


function(api, options)


  • options {object} - optionally control what can be included
  • options.jsx {boolean} - default false, pass true if you want react; pass an object for more customization (passed to react preset)
  • options.commonjs {boolean} - default false, pass non-falsey value to transform ESModules to CommonJS
  • options.typescript {boolean} - default false, includes the TypeScript preset
  • options.development {boolean} - default false, disables few plugins; when it is true and options.jsx is enabled (true or object) we add options.jsx.development: true too
  • options.minifyBuiltins {boolean} - default false, includes babel-plugin-minify-builtins
