# 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
|
|
```js
|
|
const timeLimit = require('time-limit-promise');
|
|
const fetch = require('node-fetch');
|
|
|
|
var fetchPromise = fetch('https://github.com/inikulin');
|
|
|
|
timeLimit(fetchPromise, 50).then(res => {
|
|
// If `fetchPromise` will be fulfilled within 50ms
|
|
// time limited promise will be fullfilled as well.
|
|
// Otherwise, it will be resolved with the `undefined` value.
|
|
});
|
|
|
|
timeLimit(fetchPromise, 50, { resolveWith: 'no content' }).then(res => {
|
|
// Same as above, but on timeout it will
|
|
// be resolved with the `no-content` value.
|
|
console.log(res); // > no-content
|
|
});
|
|
|
|
|
|
timeLimit(fetchPromise, 50, { rejectWith: new Error('timeout') }).catch(err => {
|
|
// Same as above, but on timeout it will
|
|
// be rejected with the provided error.
|
|
console.log(err.message); // > timeout
|
|
});
|
|
|
|
```
