Package Exports

@babel/preset-react

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@babel/preset-react) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Babel preset for all React plugins.

This preset always includes the following plugins:

And with the development option:

Note: Flow syntax support is no longer enabled in v7. For that, you will need to add the Flow preset.

Installation

You can also check out the React Getting Started page

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

Usage

Via `.babelrc` (Recommended)

.babelrc

{
  "presets": ["@babel/react"]
}

Via CLI

babel --presets @babel/react script.js

Via Node API

require("@babel/core").transform("code", {
  presets: ["@babel/react"]
});

Options

`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.

This is useful when combined with either a babelrc.js or env option in a .babelrc configuration:

babelrc.js

module.exports = {
  presets: [
    ["@babel/react", {
      development: process.env.BABEL_ENV === "development"
    }],
  ],
}

.babelrc

Note: the env option will likely get deprecated soon

{
  "presets": ["@babel/react"],
  "env": {
    "development": {
      "presets": [
        ["@babel/react", { "development": true }]
      ]
    }
  }
}
