WebSocket Server vs Server-Sent Events

Developers should use a WebSocket server when building applications that demand low-latency, real-time communication, such as collaborative tools, live notifications, or interactive dashboards 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.

WebSocket Server

Nice Pick

Developers should use a WebSocket server when building applications that demand low-latency, real-time communication, such as collaborative tools, live notifications, or interactive dashboards

Pros

• It's particularly valuable in scenarios where traditional HTTP request-response cycles are inefficient, such as streaming data or maintaining persistent connections for multiplayer games or IoT device monitoring
• Related to: websocket-client, http-protocol

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

These tools serve different purposes. WebSocket Server is a tool while Server-Sent Events is a concept. We picked WebSocket Server based on overall popularity, but your choice depends on what you're building.

The Bottom Line

WebSocket Server wins

Based on overall popularity. WebSocket Server is more widely used, but Server-Sent Events excels in its own space.
