@visma/react-intl-helpers

Modular messages.properties, loaded dynamically.

Example

webpack.config.js:

module.exports = {
  module: {
    rules: [
      {
        test: /\.properties$/,
        use: "@visma/react-intl-helpers/cjs/loader"
      }
    ]
  }
};

Project structure:

my-app/
  dist/intl/                              // generated
    messages.1f87c6b2907b3c71.json        // defaults
    messages.en-US.64c397a24b33b0e8.json  // defaults + en + en-US
    messages.en.f6ddad6c6db9e386.json     // defaults + en
    messages.fi.7ad0b2e9bd60b8b2.json     // defaults + fi
  src/
    intl/
      messages.properties
      messages_fi.properties
    App.js
  node_modules/some-package/messages/
    messages.properties
    messages_fi.properties
    messages_en.properties
    messages_en_US.properties

Directory should contain only messages[_language[_COUNTRY]].properties files. Files are added automatically to the build, if message ids are imported from messages.properties. Final ids are namespaced - same keys in different directories are allowed.

messages.properties:

title = Intl Example
some.thing = Some thing
