Why Rabbit Relay?

amqplib is powerful, but it’s low-level. Rabbit Relay keeps “real RabbitMQ concepts” (exchanges, queues, routing keys), and adds:

• Type-safe events (typed payloads + versioning)
• Cleaner publish / consume APIs (less boilerplate)
• Explicit topology & ownership (no hidden abstractions)
• Reliable defaults (so every service doesn’t reinvent the same setup)

If you already use RabbitMQ and you want a better TypeScript developer experience, Rabbit Relay is for you.

Installation

npm i @bitspacerlabs/rabbit-relay

Tip: Rabbit Relay ships TypeScript-first and supports both ESM and CommonJS builds.

Quickstart (typed events)

import { RabbitMQBroker, event } from "@bitspacerlabs/rabbit-relay";

const broker = new RabbitMQBroker("example.service");

// Create a publisher bound to your queue + exchange
const pub = await broker
  .queue("example.q")
  .exchange("example.exchange", { exchangeType: "topic" });

// Define typed events (name + version)
const send = event("send", "v1").of<{ message: string }>();

// Build a typed API and publish
const api = pub.with({ send });
await api.send({ message: "hello world" });

Direct publish (produce)

import { RabbitMQBroker, event } from "@bitspacerlabs/rabbit-relay";

const broker = new RabbitMQBroker("example.publisher");

const pub = await broker
  .queue("example.q")
  .exchange("example.direct", { exchangeType: "direct" });

const hello = event("hello", "v1").of<{ msg: string }>();

await pub.produce(hello({ msg: "world" }));

When to use Rabbit Relay

• You already use RabbitMQ
• You want type-safe events
• You prefer explicit topology and ownership
• You don’t want “magic” abstractions

Project status

Rabbit Relay is actively evolving. If something is unclear or missing, please open an issue (or start a discussion) with:

• what you’re trying to build
• the RabbitMQ pattern you’re using (pub/sub, work queue, RPC, etc.)
• a small code snippet
