WebSocket API vs Long Polling

Developers should use the WebSocket API when building applications that require real-time, two-way communication, such as collaborative editing tools, live notifications, or multiplayer games, as it reduces latency and overhead compared to polling with HTTP meets developers should learn long polling when building applications that need real-time features but cannot use websockets due to browser compatibility or infrastructure constraints. Here's our take.

WebSocket API

Developers should use the WebSocket API when building applications that require real-time, two-way communication, such as collaborative editing tools, live notifications, or multiplayer games, as it reduces latency and overhead compared to polling with HTTP

WebSocket API

Nice Pick

Developers should use the WebSocket API when building applications that require real-time, two-way communication, such as collaborative editing tools, live notifications, or multiplayer games, as it reduces latency and overhead compared to polling with HTTP

Pros

  • +It is particularly valuable in scenarios where frequent, fast updates are critical, like stock trading platforms or IoT device monitoring, as it avoids the inefficiencies of repeated HTTP requests
  • +Related to: javascript, node-js

Cons

  • -Specific tradeoffs depend on your use case

Long Polling

Developers should learn long polling when building applications that need real-time features but cannot use WebSockets due to browser compatibility or infrastructure constraints

Pros

  • +It is particularly useful for scenarios like live chat, stock tickers, or collaborative editing tools where immediate data updates are critical
  • +Related to: websockets, server-sent-events

Cons

  • -Specific tradeoffs depend on your use case

The Verdict

Use WebSocket API if: You want it is particularly valuable in scenarios where frequent, fast updates are critical, like stock trading platforms or iot device monitoring, as it avoids the inefficiencies of repeated http requests and can live with specific tradeoffs depend on your use case.

Use Long Polling if: You prioritize it is particularly useful for scenarios like live chat, stock tickers, or collaborative editing tools where immediate data updates are critical over what WebSocket API offers.

The Bottom Line
WebSocket API wins

Developers should use the WebSocket API when building applications that require real-time, two-way communication, such as collaborative editing tools, live notifications, or multiplayer games, as it reduces latency and overhead compared to polling with HTTP
