0-Deps, simple and fast async generator library for browser and NodeJS.

Usage

Create deferred token

import { defer } from 'asygen';

const result = defer();

console.log(result.status); // pending

task.once('data', error.resolve);
task.once('error', error.reject);
await result.promise;

console.log(result.status); // resolved or rejected

Convert events to asyncGenerator

import { once } from 'node:events';
import { generatorify, Task } from 'asygen';

// send data from the event until process exit
const task: Task = async (send) => {
  process.on('data', send);
  await once(process, 'exit');
};

for await (const data of generatorify(task)) {
  // handle data
}
