REST vs WebSocket

The architectural style that made APIs boringly reliable, but sometimes too rigid for modern needs meets http's chatty cousin. Here's our take.

REST

Nice Pick

The architectural style that made APIs boringly reliable, but sometimes too rigid for modern needs.

Pros

• Stateless design simplifies scaling and caching
• Uses standard HTTP methods for predictable operations
• Widely supported across languages and platforms

Cons

• Can lead to over-fetching or under-fetching data
• Lacks built-in real-time capabilities

WebSocket

HTTP's chatty cousin. Real-time without the constant handshakes.

Pros

• Full-duplex communication reduces latency for real-time apps
• Persistent connection eliminates HTTP overhead per message
• Widely supported in modern browsers and servers

Cons

• Requires explicit connection management and error handling
• Can be tricky with firewalls and proxies that block non-HTTP traffic

The Verdict

Use REST if: You want stateless design simplifies scaling and caching and can live with can lead to over-fetching or under-fetching data.

Use WebSocket if: You prioritize full-duplex communication reduces latency for real-time apps over what REST offers.

The Bottom Line

REST wins

The architectural style that made APIs boringly reliable, but sometimes too rigid for modern needs.
