Installation

First create a .env file, a sample sample.env is provided and it works with in Docker container mentioned below cp sample.env .env Likewise for running tests, a separate test.env file is needed (to provice test-only database and different port for express) cp test.env test.env Make sure to modify these .env files to point to mongodb server address. Finally install npm packages. npm install

Running in Docker

docker-compose up --build this will build two containers, one for nore and another for mongodb. The mongodb can be accessed from the node container by the server name mongo for example mongodb://mongo:27017/docker-node-mongo

Running locally

npm run dev

Running tests

npm t or npm run test

Environment varibles

• MONGO_URI: for mongoose to connect to mongodb
• MAX_DEVICES: this was provided as strict requirement, but it could be more useful as configurable. That is the number each gateway can have of devices.
• PORT: the port which express will listen on.
