@sideband/runtime

Transport-agnostic runtime primitives: peer wiring, frame routing, and RPC correlation utilities. Ships zero transport/UI code—pair it with @sideband/transport-* and @sideband/rpc.

Install

bun add @sideband/runtime

Quick use

import { RpcCorrelationManager } from "@sideband/runtime";
import { createRpcRequest, decodeRpcEnvelope, encodeRpcEnvelope } from "@sideband/rpc";
import { generateFrameId } from "@sideband/protocol";

// Track pending RPCs with timeouts
const correlator = new RpcCorrelationManager(10_000);

// Outbound request
const cid = generateFrameId();
const request = createRpcRequest("user.get", cid, { id: 42 });
const wireBytes = encodeRpcEnvelope(request);
const pending = correlator.registerRequest(cid);

// ...send wireBytes inside a MessageFrame over your transport...

// Inbound response
const responseBytes = /* MessageFrame.data from remote peer */;
const envelope = decodeRpcEnvelope(responseBytes);
correlator.matchResponse(envelope.cid, envelope);

const response = await pending; // resolved or rejected on timeout/clear()

What it provides

RpcCorrelationManager: promise-based request/response tracking with timeouts and cleanup
Runtime scaffolding without transport coupling; safe to embed in browser, Node, or service hosts
Helpers to clear/reject all pending work when transports disconnect or peers drop
