how to import node npm module in angular 6

Question

I have installed the package

npm install local-devices

and imported it in angular.json as

"scripts": [
    "./node_modules/local-devices/index.js"
]

and declared as global variable in src/typings.d.ts

declare let findLocalDevices: any

Below, package files structure and index.js of local-devices package

then tried to use it in a component as

console.log(findLocalDevices())

but got error

findLocalDevices is not defined

How to import it, please guide!!!

Answer 1

import * as findLocalDevices from 'local-devices'

and inside any method use it as

ngOnInit() {
   console.log(findLocalDevices());
}
