NodeJS Timeout a Promise if failed to complete in time

Question

How can I timeout a promise after certain amount of time? I know Q has a promise timeout, but I\'m using native NodeJS promises and they don\'t have .timeout function.

While the answers here are valid, you should not try to reinvent the wheel and just use one of the dozens available packages on NPM for the self-resolving promise.

Here's one example from NPM:

const { TimeoutResolvePromise, TimeoutRejectPromise } = require('nodejs-promise-timeout');
const TIMEOUT_DELAY = 2000;

// This promise will reject after 2 seconds:
let promise1 = new TimeoutRejectPromise(TIMEOUT_DELAY, (resolve, reject) => {
  // Do something useful here, then call resolve() or reject()
});
