@newsteam/babel-preset

This package provides a preset for babel.

Usage

A single babel preset is exported.

Our default export contains all of our babel plugins and presets. It requires the following peer dependencies:

    @babel/core

Installation

• Install the shared configuration:

npm install --save-dev @newsteam/babel-preset

• Install the shared configuration peer dependencies (npm 5+):

npx install-peerdeps --dev @newsteam/babel-preset

• Add "@newsteam/babel-preset" or your "presets" array in to your .babelrc.

Configuration

targets

string | Array<string> | { [string]: string }, defaults to {}.

Describes the environments you support/target for your project.

This can either be a browserslist-compatible query:

{
  "targets": "> 0.25%, not dead"
}

Or an object of minimum environment versions to support:

{
  "targets": {
    "chrome": "58",
    "ie": "11"
  }
}

Example environments: chrome, opera, edge, firefox, safari, ie, ios, android, node, electron.

Sidenote, this uses @babel/preset-env under the hood, so if no targets are specified it will transform all ECMAScript 2015+ code by default.

addModuleExports

boolean, defaults to false.

Enables the export default module.exports that was turned off in Babel 6.

debug

boolean, defaults to false.

Outputs the targets/plugins used and the version specified in plugin data version to console.log.

development

boolean, defaults to false.

Toggles plugins that aid in development, such as @babel/plugin-transform-react-jsx-self and @babel/plugin-transform-react-jsx-source.

Maintenance

You can run tests with npm test.
