2 Node.js utilities: a thread worker pool and a promise queue
Thread worker pool
Create a thread pool, set maximum number of parallel threads to os.cpus().length - 1, maximum idle duration to be 1 minute.
import os from 'os';
const pool = new Pool(os.cpus().length - 1, 6000, {
initializer: {file: 'source-map-support/register'},
cwd: 'dist'
});
// Add 1 task to thread pool
const donePromise = pool.submit({
file: 'worker-file.js',
exportFn: 'default',
args: []
});Author your worker-file.js file
export default function(): Promise<Date> {
return new Promise(resolve => setTimeout(() => resolve(new Date()), 1000));
}
