time-limit-promise

Fulfill long runinng promises on timeout.

Unlike other implementations on npm it has some nice extra features:

• You can both reject and resolve promises on timeout
• You can provide custom value with which promise will be rejected or resolved on timeout
• Unrefs promise timer, so it will not block your app from exit.
• Uses Promise implementation of the passed promise: no external implementation dependencies, no global Promise dependencies

Install

npm install time-limit-promise

Usage

1const timeLimit = require('time-limit-promise');
2const fetch     = require('node-fetch');
3
4var fetchPromise = fetch('https://github.com/inikulin');
5
6timeLimit(fetchPromise, 50).then(res => {
7    // If `fetchPromise` will be fulfilled within 50ms
8    // time limited promise will be fullfilled as well.
9    // Otherwise, it will be resolved with the `undefined` value.
10});
11
12timeLimit(fetchPromise, 50, { resolveWith: 'no content' }).then(res => {
13    // Same as above, but on timeout it will
14    // be resolved with the `no-content` value.
15    console.log(res); // > no-content
16});
17
18
19timeLimit(fetchPromise, 50, { rejectWith: new Error('timeout') }).catch(err => {
20    // Same as above, but on timeout it will

22    console.log(err.message); // > timeout
23});
