Roadmap towards Colyseus v1.0

Colyseus is an independent open-source project that has been around since 2015. The project has been used in production by several indies and companies and has been battle-tested in many different scenarios. The project is currently stable, but there are still many features and improvements that we’d like to add.

• General improvements:
  • Add request/response model to rooms (#331)
  • Introduce the concept of “low priority” and “high priority” messages. Drop “low priority” messages if clients are under backpressure.
  • Introduce “version check” to allow native SDKs to communicate with newer versions of the server
• Database:
  • Introduce an official database recommendation tool. The recommendation should be used on the documentation, official examples, and initial template project. (See Database)
• Matchmaking:
  • SQL Driver - Provide a SQL driver as alternative to @colyseus/redis-driver (should support SQLite / PostgreSQL, possibly on top of Kysely)
  • Improve filtering and sorting options
  • New “queue” matchmaking type:
    • A queue would keep more clients than needed before starting a match
    • User specifies logic that combines clients into a new room
    • Reserve seats for selected clients and redirect them to the newly created room
• State Sync:
  • @colyseus/schema - Bidirectional schema instances:
    • Allow to send schema instance updates from client to server
    • Wild idea: support RPC calls via schema instances (?)
    • Client-side prediction:
      • Allow to specify client-side prediction techniques on the client-side (?)
    • Decouple @colyseus/schema from the core:
      • Allow to use other serialization methods for the state
      • Yjs (CRDT) connection provider via Colyseus Rooms.
• Full-stack + TypeScript Improvements:
  • Allow to specify client.auth and client.userData types on the server-side only once
  • Allow to infer types for room message and payload definitions from client-side (room.send())
  • Allow to infer http routes and request/response body types from client-side (client.http.*)
• WebTransport:
  • Improve and stabilize WebTransport support
• More SDKs:
  • Fork and support a Godot SDK (gsioteam/godot-colyseus)
