🤹‍ Usage

Installation

npm install --save-dev babel-preset-amex

Add to your .babelrc file

{
  "presets": ["amex"]
}

Options

By default babel-preset-amex will transpile for the "last 2 versions", "not dead" browsers, and CommonJS module syntax.

{
  "presets": [[
    "amex",
    {
      "serverOnly": true,
      "modern": true,
      "moduleFormat": "esm"
    }
  ]]
}

serverOnly - Will transpile only for node. modern - Will transpile for common browsers n-1. moduleFormat - Will transpile to ECMAScript module syntax. Any string other than "esm" will transpile to CommonJS module syntax.

Customizing Babel Config

Babel Preset Amex includes the following:

Presets

• preset-env
• preset-react

Plugins

• plugin-syntax-dynamic-import
• plugin-proposal-class-properties
• plugin-proposal-export-default-from
• plugin-proposal-optional-chaining
• babel-plugin-transform-react-remove-prop-types

If you wish to re-configure any of those presets do not redefine them within your .babelrc. Instead you can configure them through the amex preset.

{
  "presets": [
    [
      "amex",
      {
        "preset-env": {},
        "preset-react": {}
      }
    ]
  ]
}
