## Install
|

|
|
```
|
|
|
|
## Usage
|
|
### Get free port
|
|
```js
|
|
const getFreePort = require('endpoint-utils').getFreePort;
|
|
|
|
getFreePort().then(port => {
|
|
console.log(port);
|
|
//> 1337
|
|
});
|
|
```
|
|
|
|
### Get multiple free ports
|
|
```js
|
|
const getFreePorts = require('endpoint-utils').getFreePorts;
|
|
|
|
getFreePorts(3).then(ports => {
|
|
console.log(ports);
|
|
//> [1337, 1338, 1339]
|
|
});
|
|
```
|
|
|
|
### Check if port is free
|
|
```js
|
|
const isFreePort = require('endpoint-utils').isFreePort;
|
|
|
|
isFreePort(1337).then(isFree => {
|
|
console.log(isFree);
|
|
//> true
|
|
});
|
|
```
|
|
|
|
### Check if hostname or IP address resolves to the current machine
|
|
```js
|
|
const isMyHostname = require('endpoint-utils').isMyHostname;
|
|
|
|
isMyHostname('inikulin').then(isMy => {
|
|
console.log(isMy);
|
|
//> true
|
|
});
|
|
|
|
isMyHostname('172.22.5.80').then(isMy => {
|
|
console.log(isMy);
|
|
//> true
|
|
});
|
|
```
|
|
|
|
### Get hostname or IP address which can be resolved to the current machine
|
|
```js
|
|
const getMyHostname = require('endpoint-utils').getMyHostname;
|
|
|
|
getMyHostname().then(hostname => {
|
|
console.log(hostname);
|
|
//> "inikulin.local"
|
|
});
|
|
```
|
|
|
|
### Get IP address of current machine
|
|
```js
|
|
const getIPAddress = require('endpoint-utils').getIPAddress;
|
|
|
|
console.log(getIPAddress());
|
|
//> "172.22.5.80"
|
|
```
