my-babel-standalone

This standalone build uses @babel/preset-env, @babel/polyfill, and whatwg-fetch to create an experience that mirrors modern browsers. It does not include presets for flow, react, and typescript.

• @babel/standalone = 5-6 mb minified
• my-babel-standalone = 1.5 mb minified

Currently, it's being used in the latest builds of modern-hta.

Example

var es5 = transform('class $ { }')

function transform (code) {
  return Babel.transform(code, {
    presets: ['env'],
    plugins: [
      'proposal-function-bind',
      'proposal-optional-chaining'
    ]
  }).code.replace(/^"use strict";\s+/, '')
}
