ngx-device-detector
An Angular 6+ 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. This library was built at KoderLabs, which is one of the best places I've worked at ❤️
Deprecated package :
New package :
If you use Angular 5, you must use v1.5.2 or earlier

## Installation
To install this library, run:
```bash
$ npm install ngx-device-detector --save
```
In your component where you want to use the Device Service
```typescript
import { Component } from '@angular/core';
...
import { DeviceDetectorService } from 'ngx-device-detector';
...
@Component({
selector: '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();
const isMobile = this.deviceService.isMobile();
const isTablet = this.deviceService.isTablet();
const isDesktopDevice = this.deviceService.isDesktop();
const isDesktopMode = this.deviceService.isDesktopModeEnabled();
console.log(this.deviceInfo);
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.
console.log(isDesktopMode); // returns if a mobile device is running in desktop mode
}
...
}
```
For SSR, you have to make sure that the User Agent is available for device detection. I.e. you'll need to provide it manually. If using ExpressJS for example:
**express.tokens.ts**
```typescript
import { InjectionToken } from '@angular/core';
import { Request, Response } from 'express';
export const REQUEST = new InjectionToken('REQUEST');
export const RESPONSE = new InjectionToken('RESPONSE');
```
**universal-device-detector.service.ts:**
```typescript
import { Inject, Injectable, Optional, PLATFORM_ID } from '@angular/core';
import { REQUEST } from 'path/to/express.tokens';
import { Request } from 'express';
import { DeviceDetectorService } from 'ngx-device-detector';
import { isPlatformServer } from '@angular/common';
@Injectable()
export class UniversalDeviceDetectorService extends DeviceDetectorService {
constructor(@Inject(PLATFORM_ID) platformId: any, @Optional() @Inject(REQUEST) request: Request) {
super(platformId);
if (isPlatformServer(platformId)) {
super.setDeviceInfo((request.headers['user-agent'] as string) || '');
}
}
}
```
**app.server.module.ts:**
```typescript
{
provide: DeviceDetectorService,
useClass: UniversalDeviceDetectorService
},
```
## Device service
Holds the following properties
- browser
- os
- device
- userAgent
- os_version
- isDesktopMode
## Helper Methods
- **isMobile() :** returns if the device is a mobile device (android / iPhone/ windows-phone etc)
- **isTablet() :** returns if the device us a tablet (iPad etc)
- **isDesktop() :** returns if the app is running on a Desktop browser.
- **isDesktopModeEnabled() :** returns if a mobile device is running in desktop mode (mobile browsers requesting desktop websites)
## Development

## Credits
The library is inspired by and based on the work from [ng-device-detector ](https://github.com/srfrnk/ng-device-detector). Also used a typescript wrapper of the amazing work in [ReTree](https://github.com/srfrnk/re-tree) for regex based needs and an Angular2 Library Creator boilerplate to get the work started fast. I.e. [Generator Angular2 library](https://github.com/jvandemo/generator-angular2-library).
