tRPC
tRPC is a TypeScript-first RPC framework that lets you define API routers on the server and import their types on the client without code generation or a separate schema file. Procedures, inputs, and outputs stay in sync through TypeScript inference, which speeds full-stack product teams.
Technical Architecture & Deep-Dive
tRPC rides on HTTP and typically JSON, mapping router paths to callable procedures. Because both sides share types, refactors break at compile time instead of silently diverging in production.
tRPC suits monorepos and trusted clients. Browser apps still should not hold third-party API keys: an edge BFF can expose a slim HTTP surface to mobile while forwarding privileged tRPC or REST calls server-side, similar to how teams front GraphQL or REST with a gateway.
Key Architectural Benefits
Implement tRPC at the Edge
Deploy lightweight API aggregation, edge caching, and secret injection in minutes without Docker containers or complex servers.
Frequently Asked Questions
Q:Can tRPC replace GraphQL?
For TypeScript-only stacks that control both ends, tRPC can replace GraphQL for many screens. GraphQL remains stronger when many unrelated clients need ad hoc field selection without shared types.
Related Architecture Concepts
Remote procedure call is a style of API design where clients invoke named procedures on a remote server as if they were local functions, usually over HTTP or a binary transport. RPC frameworks handle serialization, routing, and sometimes type generation so callers pass arguments and receive typed results.
Type-safe API contracts use shared type definitions or schemas so the compiler can verify that clients and servers agree on request and response shapes. Mismatches, such as a renamed field, surface as build errors instead of runtime crashes in production.
GraphQL is a query language and runtime for APIs in which clients send a query describing exactly the fields they need, and the server returns JSON matching that shape. A strongly typed schema defines available data, and a single endpoint replaces many REST routes.
Backend for Frontend (BFF) is an architectural pattern where a dedicated gateway layer is created for a specific frontend client (e.g., iOS, Android, React). Instead of clients calling multiple generic backend APIs, the edge BFF aggregates upstream calls, injects credentials, and strips unneeded payload fields before transmission.
Ready-to-Use Edge Recipes
To solve backend for frontend without express or docker, never execute unauthenticated requests or embed private tokens directly in client bundles. RealComposer acts as a sub-10ms edge gateway running on Cloudflare Workers that securely injects credentials from your Secret Vault, normalizes responses, and prevents unauthorized API usage. Route calls through your RealComposer edge URL to guarantee complete privacy, robust origin validation, and low mobile latency.
