Integration boundary I am designing the request/response layer between a Socket.io browser client and a Node.js server (Socket.io v4 assumed on both ends). The client emits events with an acknowledgment timeout, and the server performs work that may outlive that timeout. I need a consistent policy for what happens on each side when the acknowledgment expires
State Synchronization Behavior Reflex maintains application state on the server and synchronizes changes to the frontend using WebSockets. This architecture utilizes a delta update mechanism to transmit only modified state variables to the client, reducing overall network traffic. Concurrency and Performance Constraints In scenarios involving high-frequency
Background Canva’s client‑side cache stores images, fonts, and templates in the browser, pulling assets from a CDN that applies a one‑hour TTL and Cache‑Control headers. When a collaborator edits a shared element, a real‑time WebSocket event is emitted, but the event does not always trigger a cache‑busting query for the updated asset. Unresolved Decision The
When using web3.eth.Contract.subscribe with a filter object, the library relies on the underlying WebSocket connection. While filters successfully offload event matching to the node to reduce noise, a significant functional gap exists when the provider disconnects and reconnects. Once the connection is re-established, the subscription is typically reactivate
Goal: Achieve zero‑downtime migration of a small NestJS 9 application that uses the Express adapter and @nestjs/websockets by enabling graceful shutdown hooks so that in‑flight HTTP requests finish before the process exits. Uncertainty: While app.enableShutdownHooks() guarantees that HTTP handlers complete, it is unclear whether the same mechanism reliably t
