@synode/adapter-composite

Composite output adapter for Synode. Fans out generated events to multiple adapters in parallel.

Install

npm install @synode/adapter-composite

Requires @synode/core as a peer dependency.

Usage

import { generate, ConsoleAdapter } from '@synode/core';
import { FileAdapter } from '@synode/adapter-file';
import { CompositeAdapter } from '@synode/adapter-composite';

const composite = new CompositeAdapter([
  new ConsoleAdapter(),
  new FileAdapter({ path: './output/events.jsonl', format: 'jsonl' }),
]);

await generate(journey, { users: 100, adapter: composite });
await composite.close();

Events are forwarded to all child adapters concurrently on each write() call. close() tears down all children in parallel.

Constructor

new CompositeAdapter(adapters: OutputAdapter[])

Accepts an array of any adapters implementing the OutputAdapter interface from @synode/core. Mix built-in adapters (Console, InMemory, Callback) with package adapters (File, HTTP, Stream) freely.
