Manual Promise Control with withResolvers

Manual Promise Control with withResolvers

Promise.withResolvers() is a modern standard (Node.js 22+) that provides a cleaner way to create a promise and its controllers simultaneously, avoiding the need to nest logic inside the Promise constructor callback.

snippet.js
javascript
const { promise, resolve, reject } = Promise.withResolvers();
 
// Useful for complex event-based logic
setTimeout(() => {
  const success = Math.random() > 0.5;
  success ? resolve('Task Done!') : reject(new Error('Failed'));
}, 1000);
 
const result = await promise;

nodejs

Breakdown
