|
$ npm install get-port

```js

Pass in a preferred port:
|
|
|
|
```js
|
|
(async () => {
|
|
console.log(await getPort({port: 3000}));
|
|
// Will use 3000 if available, otherwise fall back to a random port
|
|
})();
|
|
```
|
|
|
|
Pass in an array of preferred ports:
|
|
|
|
```js
|
|
(async () => {
|
|
console.log(await getPort({port: [3000, 3001, 3002]}));
|
|
// Will use any element in the preferred ports array if available, otherwise fall back to a random port
|
|
})();
|
|
```
|
|
|
|
## API
|
|
|
|
### getPort([options])
|
|
|
|
Returns a `Promise` for a port number.
|
|
|
|
#### options
|
|
|
|
Type: `Object`
|
|
|
|
##### port
|
|
|
|
Type: `number | number[]`
|
|
|
|
A preferred port or an array of preferred ports to use.
|
|
|
|
##### host
|
|
|
|
Type: `string`

## Beware
|
|
|
|
There is a very tiny chance of a race condition if another service starts using the same port number as you in between the time you get the port number and you actually start using it.
