🌹 @sharyn/babel-preset

You can use this package as a standalone, but I recommend following the development setup tutorial to also install ESLint, Flow, Jest, React, and their Babel-related plugins.

🌹 Install

Minimal install:

yarn add --dev @sharyn/babel-preset @babel/core

Add to your package.json:

"babel": {
  "presets": [
    "@sharyn"
  ]
},

🌹 Auto-configured Modules

The following supported modules are automatically configured for Babel if they are detected in your package.json:

• @babel/plugin-proposal-do-expressions – To use do { } expressions
• @babel/plugin-proposal-nullish-coalescing-operator – To use isUndef ?? 'default'
• @babel/plugin-proposal-optional-chaining – To use isUndef?.property
• @babel/plugin-proposal-pipeline-operator – To use 'hello' |> console.log
• @babel/plugin-syntax-dynamic-import – Dynamic import()
• @babel/preset-env – The latest Babel preset
• @babel/preset-flow – The Babel preset for Flow
• @babel/preset-react – The Babel preset for React
• babel-plugin-flow-react-proptypes – Generate PropTypes from Flow annotations
• babel-plugin-module-resolver – To import from 'foo' instead of '../../foo'

See the implementation.

Note: Flow does not support the pipeline operator yet.
