Answer 1

You can use, ngx-device-detector

ngx-device-detector is An Angular 2 (and beyond) powered AOT compatible device detector that helps to identify browser, os and other useful information regarding the device using the app. The processing is based on user-agent.

Installation:

To install this library, run:

$ npm install ngx-device-detector --save

Usage:

Import DeviceDetectorModule in your app.module.ts

  import { NgModule } from '@angular/core';
  import { DeviceDetectorModule } from 'ngx-device-detector';
  ...
  @NgModule({
    declarations: [
      ...
      LoginComponent,
      SignupComponent
      ...
    ],
    imports: [
      CommonModule,
      FormsModule,
      DeviceDetectorModule.forRoot()
    ],
    providers:[
      AuthService
    ]
    ...
  })

In your component where you want to use the Device Service

import { Component } from '@angular/core';
  ...
  import { DeviceDetectorService } from 'ngx-device-detector';
  ...
  @Component({
    selector: 'home',  // <home></home>
    styleUrls: [ './home.component.scss' ],
    templateUrl: './home.component.html',
    ...
  })

  export class HomeComponent {
    deviceInfo = null;
    ...
    constructor(..., private http: Http, private deviceService: DeviceDetectorService) {
      this.epicFunction();
    }
    ...
    epicFunction() {
      console.log('hello `Home` component');
      this.deviceInfo = this.deviceService.getDeviceInfo();
      console.log(this.deviceInfo);
    }
    ...
  }

Device service:

Holds the following properties:

• browser
• os
• device
• userAgent
• os_version

You can use angular-device-information is a powerful angular package to detect operating system and version

npm i angular-device-information

 import { Component } from '@angular/core';
 ...
 import { AngularDeviceInformationService } from 'angular-device-information';
 ...
 @Component({
   selector: 'home',  // <home></home>
   styleUrls: [ './home.component.scss' ],
   templateUrl: './home.component.html',
   ...
 })

 export class HomeComponent {
 
   constructor(private deviceInformationService: AngularDeviceInformationService) {
 
      console.log(deviceInformationService.isMobile());  // returns if the device is a mobile device (android / iPhone / windows-phone etc)
      console.log(deviceInformationService.isTablet());  // returns if the device is a tablet (tablet iPad etc)
      console.log(deviceInformationService.isDesktop()); // returns if the app is running on a Desktop browser.
      console.log(deviceInformationService.getDeviceType()); // returns if the app is running on a Desktop browser.
      console.log(deviceInformationService.getDeviceInfo().os);  // returns os name like Windows/Andtoid/iOS/Linux/Mac OS X etc
      console.log(deviceInformationService.getDeviceInfo().osVersion);  // returns os version like 10/8.1/7 ...etc
      console.log(deviceInformationService.getDeviceInfo().browser);  // returns browser name like chrome/firefox ...etc
      console.log(deviceInformationService.getDeviceInfo().browserVersion);  // returns browser version as number
      console.log(deviceInformationService.getDeviceInfo().browserMajorVersion);  // returns full browser version as number
      console.log(deviceInformationService.getDeviceInfo().screen_resolution);  // returns screnn size like 1390x860/640x800 ...etc
      console.log(deviceInformationService.getDeviceInfo().cookies);  // returns cookies enabled or no 
      console.log(deviceInformationService.getDeviceInfo().userAgent);  // returns userAgent
   }
   
 }
