Polling vs Server-Sent Events
Developers should use polling in scenarios where real-time updates are not critical, server-side push technologies (like WebSockets or Server-Sent Events) are unavailable or too complex, or for lightweight applications with low-frequency data changes 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.
Polling
Developers should use polling in scenarios where real-time updates are not critical, server-side push technologies (like WebSockets or Server-Sent Events) are unavailable or too complex, or for lightweight applications with low-frequency data changes
Polling
Nice PickDevelopers should use polling in scenarios where real-time updates are not critical, server-side push technologies (like WebSockets or Server-Sent Events) are unavailable or too complex, or for lightweight applications with low-frequency data changes
Pros
- +It is commonly applied in APIs for checking job statuses (e
- +Related to: long-polling, webhooks
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 Polling if: You want it is commonly applied in apis for checking job statuses (e 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 Polling offers.
