WebSocket

Best Practices

• Reconnect in WebSocket.onclose() call back

• Type different Requests and Responses, for example:

  • LoadRequest and LoadResponse

Code:

• https://github.com/aizatto/crdt-prototype/blob/master/packages/frontend/src/crdt/CRDTWebSocket.ts

• https://github.com/aizatto/crdt-prototype/blob/master/packages/backend-express/src/server.ts

• https://github.com/aizatto/crdt-prototype/blob/master/packages/shared/src/enums.ts

Note: Socket.IO is not a WebSocket implementation. Although Socket.IO indeed uses WebSocket as a transport when possible, it adds some metadata to each packet: the packet type, the namespace and the ack id when a message acknowledgement is needed. That is why a WebSocket client will not be able to successfully connect to a Socket.IO server, and a Socket.IO client will not be able to connect to a WebSocket server (like ws://echo.websocket.org) either. Please see the protocol specification here.
