morse-back is a work queue for text messages sent from a mobile device to be processed by a board with a control program from the morse project to convert text messages to the Morse code to signal tehm through light and sound.

• Node.js, npm >= 8.1.3, >= 5.1.0
• Redis >= 3.2.9
• Docker, docker-compose >= 17.06.0, >= 1.14.0 (optional)

Ensure that the following host can be resolved into an IP address of the actual services on your setup

• morse-queue-db: resolve to an instance of a Redis database with the queue

There are many approaches that you can use for name resolution. You can add entries to /etc/hosts manually, setup a DNS server or utilize Docker Networks to manage /etc/hosts files across containers automatically.

Create an .env file with parameters for all the components.

# Database
MORSE_DATABASE_HOST=the location of the Redis database server (morse-queue-db by default)
MORSE_DATABASE_PORT=the database port (6379 by default)

# Server
MORSE_SERVER_PORT=the port to be used by the server (7474 by default)

Install dependencies, ensure that Redis is running, and start the server.

npm install # to install dependencies
npm start   # to start the server

Instead of setting up the system manually with all its dependencies, you can also use Docker with Docker Compose to start the service right away.

You can issue the following commands from the project directory

• docker-compose up: to start the service

• docker-compose up -d: to start the service in the background

• docker-compose down: to stop the service

• docker-compose -f docker-compose.yml -f docker-compose.development.yml: to mount the project directory on the host machine under a project directory inside the container to allow instant source changes throughout development without rebuilds

A prebuilt Docker image can also be found for download from Docker Hub at toksaitov/morse-back.
