Folder Structure

After bootstrapping a new application, your project should look like this:

• src/: Directory containing all the JavaScript files (for example React components) for the application. More specifically, it should include the following:
  • src/index.js: The application entry point. Contains the import statements to render the React application. The path to this file is also defined in the webpack.config.<env>.js as the entryPoint.
  • src/routes.js: Defines the sub routes and components rendered by the application. The main route is defined in the <EntryPoint> component and is loaded asynchronously using Code-Splitting.
  • src/load-messages.js: See Translations.
  • src/i18n: Contains the translations from the Intl messages.
  • src/components/entry-point: Contains the <EntryPoint> component which must:
    • Use the <ApplicationShell> component to load the core logic of the application (including layout elements like the left hand and top navigation).
    • Define a <Route> component to handle requests matching the main application route path.
• env.json: See Runtime Configuration
• webpack.config.<env>.js: Contains the setup for getting the webpack configurations for development and production.
• jest.test.config.js: Contains configurations for running tests using a Jest runner.
• dist/: Contains the production bundles (created once you run yarn build).
• package.json: Contains the dependencies to work on the project and npm scripts to perform important tasks (for example yarn test, yarn start, yarn build, yarn i18n:build, etc.).
