Ionic5, Angular11 and Bootstrap 5 came and if you are new then you must check below links:

  1. Angular11 Basic Tutorials
  2. Ionic 5
  3. Bootstrap 5
  4. For more Angular Free Templates click here

Friends now I proceed onwards and here is the working code snippet and use this carefully to avoid the mistakes:

1. Firstly friends we need fresh Ionic 5 angular 11 setup and for this we need to run below commands but if you already have  Ionic 5 angular 11 setup then you can avoid below commands. Secondly we should also have latest node version installed on our system:

Guys you can skip this first step if you already have ionic 5 fresh setup:

npm install -g @ionic/cli

ionic start myapp blank

cd myapp

2. Now friends we need to run below commands into our project terminal to install ngx-webcam access  modules into our ionic application: 

npm i ngx-webcam

ionic serve

3. Now friends we need to add below code into myapp/src/app/app.component.html file:

<webcam [height]="500" [width]="500" [trigger]="triggerObservable" (imageCapture)="handleImage($event)"></webcam>

<!-- Button Takes Photo -->
<button class="actionBtn" (click)="triggerSnapshot();">Take A Snapshot</button>

<!-- Snapshot Div where image will be shown -->
<div class="snapshot" *ngIf="webcamImage">
  <h2>Take your image or get another</h2>
  <img [src]="webcamImage.imageAsDataUrl"/>
</div>

4. Now friends we need to add below code into myapp/src/app/app.module.ts file:

...
import {WebcamModule} from 'ngx-webcam';
...
imports: [
    ...
    WebcamModule
]

5. Now friends we need to add below code into myapp/src/app/app.component.ts file:

...
import {WebcamImage} from 'ngx-webcam';
import {Subject, Observable} from 'rxjs';
...
export class AppComponent {
...
   // latest snapshot
   public webcamImage: WebcamImage = null;

   // webcam snapshot trigger
   private trigger: Subject<void> = new Subject<void>();
   triggerSnapshot(): void {
    this.trigger.next();
   }
   handleImage(webcamImage: WebcamImage): void {
    console.info('received webcam image', webcamImage);
    this.webcamImage = webcamImage;
   }
  
   public get triggerObservable(): Observable<void> {
    return this.trigger.asObservable();
   }
}

Now we are done friends  also and If you have any kind of query or suggestion or any requirement then feel free to comment below. In my next post I will come with more Ionic 5 working demos.

Note: Friends, I just tell the basic setup and things, you can change the code according to your requirements. For better understanding must watch video above.

I will appreciate that if you will tell your views for this post. Nothing matters if your views will be good or bad.

Jassa

Thanks
