babel-preset-airbnb

A babel preset for transforming your JavaScript for Airbnb.

Currently contains transforms for all standard syntax that is stage 4 (ES2017) or stage 3, except for the following:

  • generators: regenerator-runtime is too heavyweight for our use.
  • async/await: regenerator-runtime is too heavyweight for our use, and async-to-promises is not yet complete enough to be safely used.
  • SIMD: this is a performance feature, so is pretty pointless to polyfill/transpile.
  • lifted template literal restrictions: we do not use tagged template literals, nor implement custom DSLs, otherwise we would enable this.

We have also enabled object rest/spread, although it is only at stage 2. It will hopefully achieve stage 3 soon.

Install

$ npm install --save-dev babel-preset-airbnb

Usage

Via .babelrc (Recommended)

.babelrc

{
  "presets": ["airbnb"]
}

Via CLI

$ babel script.js --presets airbnb

Via Node API

require("babel-core").transform("code", {
  presets: ["airbnb"]
});

Targeting Environments

This module uses babel-preset-env to target specific environments.

Please refer to babel-preset-env#targets for a list of available options.

For a list of browsers please see browserlist.

You may override our default list of targets by providing your own targets key.

{
  "presets": [["airbnb", {
    "targets": {
      "chrome": 50,
      "explorer": 11,
      "firefox": 45
    }
  }]]
}

The following transpiles only for Node v6.

{
  "presets": [["airbnb", {
    "targets": {
      "node": 6
    }
  }]]
}

If you wish, you can also inherit our default list of browsers and extend them using additionalTargets.

{
  "presets": [["airbnb", {
    "additionalTargets": {
      "chrome": 42,
      "explorer": 8
    }
  }]]
}
