|
```
|
|
|
|
```js
|
|
const detect = require('detect-port');
|
|
|
|
/**
|
|
* callback usage
|
|
*/
|
|
|
|
detect(port, (err, _port) => {
|
|
if (err) {
|
|
console.log(err);
|
|
}
|
|
|
|
if (port == _port) {
|
|
console.log(`port: ${port} was not occupied`);
|
|
} else {
|
|
console.log(`port: ${port} was occupied, try port: ${_port}`);
|
|
}
|
|
});
|
|
|
|
/**
|
|
* for a yield syntax instead of callback function implement
|
|
*/
|
|
|
|
const co = require('co');
|
|
|
|
co(function *() {
|
|
const _port = yield detect(port);
|
|
|
|
if (port == _port) {
|
|
console.log(`port: ${port} was not occupied`);
|
|
} else {
|
|
console.log(`port: ${port} was occupied, try port: ${_port}`);
|
|
}
|
|
});
|
|
|
|
/**
|
|
* use as a promise
|
|
*/
|
|
|
|
detect(port)
|
|
.then(_port => {
|
|
if (port == _port) {
|
|
console.log(`port: ${port} was not occupied`);
|
|
} else {
|
|
console.log(`port: ${port} was occupied, try port: ${_port}`);
|
|
}
|
|
})
|
|
.catch(err => {
|
|
console.log(err);
|
|
});
|
|
|
|
```
