@atlassian/i18n-properties-loader

A loader for i18n *.properties files that can be used with webpack or rspack in Atlassian Server products and plugins.

Motivation

If your work with the modern Front-End Server code there is a good chance you are already using the Atlassian Web-Resource webpack Plugin. If you did configure your webpack to use development server you might be missing displaying translation phrases right now.

The @atlassian/i18n-properties-loader can help you with solving that problem. It's a webpack loader that allows you displaying translation phrases during your development workflow and at the same time uses the WRM.

For more information about the translations system check the Atlassian Development documentation page:

Installation

npm install @atlassian/i18n-properties-loader --save-dev

Usage example

// webpack.config.js

const myI18nFiles = [
  'foo/i18n/my-translation-file.properties',
  'foo/bar/i18n/my-other-translation-file.properties',
  'bar/i18n/some-translation-file.properties',
];

module.exports = {
  module: {
    rules: [
      {
        test: /\.jsx?$/,
        include: ['src'],

        use: [
          {
            loader: '@atlassian/i18n-properties-loader',
            options: {
              i18nFiles: myI18nFiles,
            },
          },

          {
            loader: 'babel-loader',
          },
        ],
      },
    ],
  },
};

Options

• i18nFiles list of paths to your *.properties files (required)
• disabled disables the loader; can we used to disabled in production bundle (optional, default false)

Creating production bundle

The loader is required only in development mode. You should remember to disable it when you are creaing production bundle.

With webpack and its mode configuration you can intercept the currently selected mode inside your webpack configuration and disable the loader accoridngly:

// webpack.config.js

module.exports = (env, argv) => {
  const isDevelopmentMode = argv.mode === 'development'; // 1. Check if we are running webpack in "development" mode

  return {
    module: {
      rules: [
        {
          test: /\.jsx?$/,
          include: ['src'],

          use: [
            {
              loader: '@atlassian/i18n-properties-loader',
              options: {
                i18nFiles,
                disabled: !isDevelopmentMode, // 2. Skip and disable loader when webpack is running in "production" mode
              },
            },

            {
              loader: 'babel-loader',
            },
          ],
        },
      ],
    },
  };
};
