babel-plugin-zbox-intl

babel-plugin-react-intl

Extracts string messages for translation from modules that use React Intl.

Note: This Babel plugin works with React Intl v2 which is in development, and 1.x of this plugin works with Babel 5, 2.x works with Babel 6.

Installation

$ npm install babel-plugin-react-intl

Usage

This Babel plugin only visits ES6 modules which import React Intl.

The default message descriptors for the app's default language will be extracted from: defineMessages(), <FormattedMessage>, and <FormattedHTMLMeessage>; all of which are named exports of the React Intl package.

Via .babelrc (Recommended)

.babelrc

{
  "plugins": [
    ["react-intl", {
        "messagesDir": "./build/messages/",
        "enforceDescriptions": true
    }]
  ]
}

Options

• messagesDir: The target location where the plugin will output a .json file corresponding to each component from which React Intl messages were extracted. If not provided, the extracted message descriptors will only be accessible via Babel's API.

• enforceDescriptions: Whether or not message declarations must contain a description to provide context to translators. Defaults to: false.

• moduleSourceName: The ES6 module source name of the React Intl package. Defaults to: "react-intl", but can be changed to another name/path to React Intl.

Via CLI

$ babel --plugins react-intl script.js

Via Node API

The extract message descriptors are available via the metadata property on the object returned from Babel's transform() API:

require('babel-core').transform('code', {
  plugins: ['react-intl']
}) // => { code, map, ast, metadata['react-intl'].messages };
