Decentraland HTTP-REST State Synchronization

Update 2020-01-23: Decentraland changed the API since this example. I’ll post an updated link if I port this.

New tutorial released

Developers and designers of Decentraland scenes will have a need to synchronize state across all players who are viewing(or inside) a scene.

Previously I discussed doing this with WebSockets but we don’t always want to use WebSockets. There’s extra processing power required with WebSockets that we can avoid by using HTTP-REST.

The interface is like this:

• GET /api/pixels
  • get all pixels
• GET /api/pixels/pixel/?x=6&y=4
  • get a single pixel at {x,y} coordinate from db
• PUT /api/pixels/pixel
  • put a new pixel into the db
• POST /api/pixels/pixel/:id
  • post an existing pixel back into the db
• DELETE /api/pixels/pixel/:id
  • delete existing pixel

That’s how we “draw” the pixels using REST.
