WebSockets

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

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

The Bottom Line

API Calls wins

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