react-intl-universal-extract

Extract default messages in application using react-intl-universal.

For example, suppose you have a file:

  render() {
    const name = 'Tony';
    return (<>
      {intl.get('hello1').d('Hello World')}
      {intl.get('hello2', {name} ).d(`Hello ${name}`)}
    </>);
  }  

This package will generate a json file which contains the extracted messages.

{
  "hello1": "Hello World",
  "hello2": "Hello {name}",
}

Note that if the default message contains variables in ES6 template strings format (Hello ${name}), it will be transformed to ICU format (Hello {name}).

Install

npm install --save-dev react-intl-universal-extract
