Remote Procedure Call (RPC)
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.
Technical Architecture & Deep-Dive
REST maps nouns and HTTP verbs to resources. RPC maps verbs directly: `createInvoice(customerId)` instead of `POST /invoices` with a body contract inferred from docs. gRPC, JSON-RPC, and tRPC are common flavors with different serialization and browser support.
RPC excels for internal service-to-service calls and strongly typed full-stack apps. Public mobile clients often still need an edge gateway that converts RPC to cache-friendly HTTP, injects secrets, and applies rate limits without exposing every internal procedure name.

Implement Remote Procedure Call (RPC) at the Edge
Deploy lightweight API aggregation, edge caching, and secret injection in minutes without Docker containers or complex servers.
Frequently Asked Questions
Q:Is REST the opposite of RPC?
They emphasize different abstractions. REST centers resources and HTTP semantics. RPC centers procedures. Many products expose REST externally and RPC internally.
Related Architecture Concepts
A REST API is a web interface that exposes data as resources identified by URLs and manipulated with standard HTTP methods such as GET, POST, PUT, and DELETE. Each request is stateless and responses are usually JSON, making REST the most common style for public and internal APIs.
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.
An API Gateway is a single entry point that sits between client applications and backend services. It routes requests, enforces authentication and rate limits, transforms payloads, and aggregates responses so clients talk to one stable endpoint instead of many internal APIs.
Microservices architecture structures an application as a collection of small, independently deployable services, each owning a single business capability and its data. Services communicate over APIs or messaging, allowing teams to build, scale, and release parts of the system separately.
Ready-to-Use Edge Recipes
To solve lightweight api gateway for jamstack and static sites, 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.
To solve backend for frontend without express or docker, never execute unauthenticated requests or embed private tokens directly in client bundles.
