Ajax Polling vs Server-Sent Events
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 sse when building applications that require real-time, server-to-client updates, such as live dashboards, chat applications, or news feeds, as it offers a lightweight and easy-to-implement alternative to websockets for one-way data flow. 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
Server-Sent Events
Developers should learn SSE when building applications that require real-time, server-to-client updates, such as live dashboards, chat applications, or news feeds, as it offers a lightweight and easy-to-implement alternative to WebSockets for one-way data flow
Pros
- +It is particularly useful in scenarios where you need to avoid the complexity of bidirectional communication or when working with HTTP/1
- +Related to: websockets, http
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 Server-Sent Events if: You prioritize it is particularly useful in scenarios where you need to avoid the complexity of bidirectional communication or when working with http/1 over what Ajax Polling offers.
