To learn more about the collab.io make sure to check out its documentation first!
This repository contains the server part of our collab.io project.
This server is the backend for the collab.io project. It provides some endpoints for user management, room CRUD and also web socket connections. It is the central communication hub for all in and outgoing websocket connections. It also makes sure that all websocket connections are authorized. The main feat of this server is that it can divide different websocket connections into multiple rooms so multiple sessions can go on at once without interfering.
In order to try out nodejs as a decent server solution we opted to try typedi which is a dependency injection solution. The main technology inspiration was provided by typestack which makes writing a server feel a lot like writing a webserver in C#/Java but with JavaScript/Typescript.
To easily being able to write controllers we opted for the package routing-controllers which lets you write controllers via annotations. This is also included in the typestack technology stack. Again, this makes it feel a lot like writing a Java Spring server for example. It's a great convenience layer.
As a database we simply chose to use mysql and for the websocket solution we used socket.io for simplicity reasons. The main focus was to focus on the frontend and on how the realtime data streams are processed and handled on the frontend.
