This sample project is managing gateways - master devices that control multiple peripheral devices. Your task is to create a REST service (JSON/HTTP) for storing information about these gateways and their associated devices. This information must be stored in the database. When storing a gateway, any field marked as “to be validated” must be validated and an error returned if it is invalid. Also, no more that 10 peripheral devices are allowed for a gateway. The service must also offer an operation for displaying information about all stored gateways (and their devices) and an operation for displaying details for a single gateway. Finally, it must be possible to add and remove a device from a gateway.

Each gateway has:

• a unique serial number (string),
• human-readable name (string),
• IPv4 address (to be validated),
• multiple associated peripheral devices. Each peripheral device has:
• a UID (number),
• vendor (string),
• date created,
• status - online/offline.

Make sure to follow all these steps exactly as explained below. Do not miss any steps or you won't be able to run this application.

To run this project, you need to install the latest version of MongoDB Community Edition first.

https://docs.mongodb.com/manual/installation/

Once you install MongoDB, make sure it's running.

Next, from the project folder, install the dependencies:

npm i

node seed.js

You're almost done! Run the tests to make sure everything is working:

npm test

All tests should pass.

node index.js

This will launch the Node server on port 3000. If that port is busy, you can set a different point in config/default.json.
