Which of the following considerations is most crucial when scaling a React application with thousands of active Websocket connections?

  • Minimize the usage of server-sent events (SSE) for real-time updates.
  • Optimize server-side code and infrastructure to handle concurrent connections.
  • Use traditional HTTP polling instead of Websockets for better scalability.
  • Decrease the number of components that subscribe to Websocket updates.
When scaling a React application with thousands of active Websocket connections, the most crucial consideration is optimizing server-side code and infrastructure to handle concurrent connections (Option 2). This ensures that the server can manage the load effectively. The other options do not address the scalability challenges associated with a large number of Websocket connections. Server-sent events (SSE) and HTTP polling are not necessarily better alternatives for real-time updates. Reducing the number of subscribing components may impact the application's functionality.
