orpc-server

Wire protocol implementation for oRPC, compatible with the official @orpc/client TypeScript package.

Protocols

RPC Protocol

Request-response and SSE streaming over a single endpoint, matching @orpc/client's RPCLink.

• Request: {"json": <input>} or {} (no input), with optional "meta" for special types
• Response: {"json": <output>} (meta omitted when empty)
• SSE: Auto-detected via ProcedureStream::size_hint() — single-value returns JSON, multi-value streams SSE events (message, done, error)

OpenAPI Protocol

REST-style routing with Route metadata, path parameter extraction, and plain JSON responses (no envelope).

Modules

• rpc — RPC encode/decode, execute_rpc, execute_rpc_auto
• sse — SSE event formatting, SseStream, subscription detection
• openapi — Route matching, OpenAPI request/response handling
• meta — Meta array parsing for special type reconstruction (Date, Set, Map, etc.)
