JavaScript Implementation of Port Detector

bash $ npm i detect-port --save
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 => {
