To install this library, run:

$ npm install ngx-device-detector --save

In your component where you want to use the Device Service

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

  export class HomeComponent {
    deviceInfo = null;
    constructor(..., private http: Http, private deviceService: DeviceDetectorService) {
    epicFunction() {
      console.log('hello `Home` component');
      this.deviceInfo = this.deviceService.getDeviceInfo();
      const isMobile = this.deviceService.isMobile();
      const isTablet = this.deviceService.isTablet();
      const isDesktopDevice = this.deviceService.isDesktop();
      console.log(isMobile);  // returns if the device is a mobile device (android / iPhone / windows-phone etc)
      console.log(isTablet);  // returns if the device us a tablet (iPad etc)
      console.log(isDesktopDevice); // returns if the app is running on a Desktop browser.

To ensure Universal has the correct User Agent for device detection, you'll need to provide it manually. If using ExpressJS for example:


import { Inject, Injectable, Optional, PLATFORM_ID } from '@angular/core';
import { REQUEST } from '@nguniversal/express-engine/tokens';
import { Request } from 'express';
import { DeviceDetectorService } from 'ngx-device-detector';
import { isPlatformServer } from '@angular/common';

export class UniversalDeviceDetectorService extends DeviceDetectorService {
  constructor(@Inject(PLATFORM_ID) platformId: any, @Optional() @Inject(REQUEST) request: Request) {
    if (isPlatformServer(platformId)) {
      super.setDeviceInfo((request.headers['user-agent'] as string) || '');


  provide: DeviceDetectorService,
  useClass: UniversalDeviceDetectorService

Change Log

Please see CHANGE_LOG.MD for the updates.


The library is inspired by and based on the work from ng-device-detector . Also used a typescript wrapper of the amazing work in ReTree for regex based needs and an Angular2 Library Creator boilerplate to get the work started fast. I.e. Generator Angular2 library.
