How to get MAC Address of system using Angular 4

Question

I need MAC Address of current system using Angular

 

I tried this

 

run this command : npm install --save getmac

 

then in component file code is

 

getMACAddress() {

require('getmac').getMac(function (err, macAddress) {

if (err) throw err

console.log(macAddress)

alert(macAddress);

})

}

 

Is there any other way to fetch the MAC Address using Angular, TypeScript, JavaScript?
