🐾 Guided Walkthrough

1. Installation

npm install

2. Run the tests

npm test

3. Start the service

npm start

The server listens on port 8080 by default. Override with the PORT environment variable if needed.

4. HTTP Endpoint

• GET /helloworld-by-language – Responds with a greeting string such as hello world @ 2024-06-01T12:34:56.000Z.

5. Configuration Environment variables provide the same configurability as the Quarkus version:

• TRANSLATION_DEFAULT_LANGUAGE (default: EN) – Two-letter code used to choose the greeting.
• TRANSLATION_FILE (default: translations.json) – File located in the resources/ directory that contains the greeting map.
• PORT (default: 8080) – Port for the HTTP server.

All translations are stored in resources/translations.json
