tRPC vs WebSocket

TypeScript's love letter to API developers meets http's chatty cousin. Here's our take.

tRPC

Nice Pick

TypeScript's love letter to API developers. Write types once, cry about mismatched schemas never.

Pros

• End-to-end type safety without code generation
• Seamless autocompletion and real-time error prevention
• Reduces boilerplate by sharing types between client and server

Cons

• Tightly coupled to TypeScript, limiting use in non-TypeScript projects
• Can feel like magic, making debugging more opaque when things go wrong

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 tRPC if: You want end-to-end type safety without code generation and can live with tightly coupled to typescript, limiting use in non-typescript projects.

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

The Bottom Line

tRPC wins

TypeScript's love letter to API developers. Write types once, cry about mismatched schemas never.
