babel-plugin-intl

Extracts string messages for translation from modules that use intl.

Note: This Babel plugin is based on babel-plugin-react-intl and works with Babel 6.

Installation

$ npm install babel-plugin-intl

Usage

This Babel plugin only visits ES6 modules which import intl.

The default message descriptors for the app's default language will be extracted from intl(), which is a default export of the intl package.

Via .babelrc (Recommended)

.babelrc

{
  "plugins": [
    [
      "intl", {
        "messagesDir": "./build/messages/",
        "enforceDescriptions": false
      }
    ]
  ]
}

Options

• messagesDir: The target location where the plugin will output a .json file corresponding to each call from which 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 intl package. Defaults to: "./intl", but can be changed to another name/path.

Via CLI

$ babel --plugins 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: ['intl']
}) // => { code, map, ast, metadata['intl'].messages };
