How to open new API endpoints

[mrcyme]

Hi,
First of all congratulation for the amazing piece of work you put together.
For an application I am building, I have been looking for a whiteboard application that enables writing objects to the board with API calls. As I could not find any board application providing such functionality (some does but not to the extent I am looking for), I looked for open source whiteboard applications and I came across yours.
I was wondering if you have any piece of advice on what I should do to be able to write object to the board with an API calls. I just need to be able to add object in the board with an API call while keeping all other functionalities available.

Thank you very much for the work you achieved !

It's been a long time since I worked on the Application, so I hope it's correct what I'm saying:

The Application works mostly by using Socket-Events. All connected clients are connected to the backend by sockets. Whenever someone does something on the board a corresponding event is sent to the backend, which in turn sends another corresponding event to all other clients.

These events can be seen here and here

You could possibly connect to the socket and send the appropriate events with the data you need and it should work.

Another alternative (the restful way) would be you write a new route in the nest-backend which could use the socket-gateway as a service. In your request you would send the fabricjs object and hand it over to the corresponding socket-gateway method.
