todos-api

TODOs API

This service is written in NodeJS, it provides CRUD operations over TODO entries. It keeps all the data in memory. CREATE and DELETE operations are logged by sending appropriate message to a Redis queue. The messages are then processed by log-message-processor.

• GET /todos - list all TODOs for a given user
• POST /todos - create new TODO
• DELETE /todos/:taskId - delete a TODO by ID

TODO object looks like this:

{
    id: 1,
    userId: 1,
    content: "Create new todo"
}

Log message looks like this:

{
    opName: CREATE,
    username: username,
    todoId: 5,
}

Configuration

The service scans environment for variables:

• TODO_API_PORT - the port the service takes.
• JWT_SECRET - secret value for JWT token processing. Must be the same amongst all components.
• REDIS_HOST - host of Redis
• REDIS_PORT - port of Redis
• REDIS_CHANNEL - channel the processor is going to listen to

Building

npm install

Running

JWT_SECRET=PRFT TODO_API_PORT=8082 npm start
