WebSockets vs GraphQL Subscriptions

Developers should learn and use WebSockets when building applications that require real-time features, such as live chat, online gaming, financial trading platforms, collaborative editing tools, or live sports updates, as it reduces latency and server load compared to polling techniques like HTTP long-polling meets developers should use graphql subscriptions when building applications that require real-time functionality, such as messaging apps, live dashboards, or multiplayer games, to avoid inefficient polling and reduce latency. Here's our take.

WebSockets

Nice Pick

Developers should learn and use WebSockets when building applications that require real-time features, such as live chat, online gaming, financial trading platforms, collaborative editing tools, or live sports updates, as it reduces latency and server load compared to polling techniques like HTTP long-polling

Pros

• It is particularly valuable in scenarios where instant data synchronization between clients and servers is critical, such as in IoT device monitoring or interactive dashboards, because it maintains an open connection for continuous data flow
• Related to: http, real-time-communication

Cons

• Specific tradeoffs depend on your use case

GraphQL Subscriptions

Developers should use GraphQL Subscriptions when building applications that require real-time functionality, such as messaging apps, live dashboards, or multiplayer games, to avoid inefficient polling and reduce latency

Pros

• They are essential in scenarios where data changes frequently and clients need instant updates without manual refreshes, enhancing user experience and system efficiency
• Related to: graphql, apollo-server

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. WebSockets is a protocol while GraphQL Subscriptions is a concept. We picked WebSockets based on overall popularity, but your choice depends on what you're building.

The Bottom Line

WebSockets wins

Based on overall popularity. WebSockets is more widely used, but GraphQL Subscriptions excels in its own space.
