Ajax Polling vs Long Polling
Developers should use Ajax Polling when building applications that require periodic data updates, such as live notifications, chat applications, or dashboards with real-time metrics, especially in environments where simpler alternatives like WebSockets or Server-Sent Events are not supported 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.
Ajax Polling
Developers should use Ajax Polling when building applications that require periodic data updates, such as live notifications, chat applications, or dashboards with real-time metrics, especially in environments where simpler alternatives like WebSockets or Server-Sent Events are not supported
Ajax Polling
Nice PickDevelopers should use Ajax Polling when building applications that require periodic data updates, such as live notifications, chat applications, or dashboards with real-time metrics, especially in environments where simpler alternatives like WebSockets or Server-Sent Events are not supported
Pros
- +It is suitable for low-frequency updates or legacy systems, but for high-frequency or low-latency needs, more efficient methods are recommended to reduce bandwidth and server overhead
- +Related to: ajax, javascript
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 Ajax Polling if: You want it is suitable for low-frequency updates or legacy systems, but for high-frequency or low-latency needs, more efficient methods are recommended to reduce bandwidth and server overhead 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 Ajax Polling offers.
Developers should use Ajax Polling when building applications that require periodic data updates, such as live notifications, chat applications, or dashboards with real-time metrics, especially in environments where simpler alternatives like WebSockets or Server-Sent Events are not supported
