@resonatehq/kafka

@resonatehq/kafka is the official Kafka transport binding for the Resonate TypeScript SDK. It replaces the default HTTP transport, routing task invocations and resumptions through Kafka topics instead.

Installation

npm install @resonatehq/kafka

Usage

Pass a Kafka transport instance when constructing Resonate:

import { type Context, Resonate } from "@resonatehq/sdk";
import { Kafka } from "@resonatehq/kafka";

const transport = new Kafka({ brokers: ["localhost:9092"] });
await transport.start();

const resonate = new Resonate({ transport });

resonate.register("foo", function* foo(ctx: Context): Generator {
  return yield* ctx.rpc("bar");
});

resonate.register("bar", function bar(_ctx: Context) {
  return "hello world";
});

const result = await resonate.run("foo.1", "foo");
console.log(result); // "hello world"

await resonate.stop();

Before running, create the required Kafka topics:

resonate
default

Start the Resonate server with Kafka enabled:

resonate dev --api-kafka-enable --aio-kafka-enable

Then run your application:

npx ts-node app.ts
