Creating a simple video call application in Ionic 8

Creating a simple video call application in Ionic 8 can be a great way to learn about integrating video communication features into mobile applications. For this example, you’ll need to use Ionic for the frontend and a service like Agora or Twilio for handling the video streams, as these platforms offer robust SDKs to simplify the process.

Here’s a basic outline of how you can create a simple video call application using Ionic 8 and Agora (one of the popular choices for video communications):

Step 1: Guys here it Set Up Your Ionic Environment

Guys make sure you have Node.js installed, then install Ionic and start a new project:

npm install -g @ionic/cli
ionic start myVideoCallApp blank --type=angular
cd myVideoCallApp

Step 2: Guys Install Required Packages

Install the necessary packages for Agora:

npm install agora-rtc-sdk-ng

You might also need to install additional tools for Angular compatibility:

npm install @angular/cdk

Step 3: Guys Setup Agora Account

1. Go to Agora.io, sign up, and create a new project.
2. Get the App ID from your Agora dashboard.
3. Optionally, for enhanced security, you can also use a token server, but for testing purposes, you can use temporary tokens generated from the Agora console.

Step 4: Guys Integrate Agora into Your Ionic App

Update your app module and component to integrate Agora. Here’s a simple setup:

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { IonicModule } from '@ionic/angular';
import { AppComponent } from './app.component';

@NgModule({
  declarations: [AppComponent],
  imports: [BrowserModule, IonicModule.forRoot()],
  bootstrap: [AppComponent]
})
export class AppModule {}

home.page.ts

Guys now create a basic video call functionality:

import { Component, OnInit, OnDestroy } from '@angular/core';
import AgoraRTC from 'agora-rtc-sdk-ng';

@Component({
  selector: 'app-home',
  templateUrl: 'home.page.html',
  styleUrls: ['home.page.scss'],
})
export class HomePage implements OnInit, OnDestroy {
  private client = AgoraRTC.createClient({ mode: 'rtc', codec: 'vp8' });

  async ngOnInit() {
    this.client.on('user-published', async (user, mediaType) => {
      await this.client.subscribe(user, mediaType);
      if (mediaType === 'video') {
        const remoteVideoTrack = user.videoTrack;
        const playerContainer = document.createElement('div');
        document.body.append(playerContainer);
        remoteVideoTrack.play(playerContainer);
      }
    });

    await this.client.join('YOUR_AGORA_APP_ID', 'your-channel-name', null, null);
    const localTracks = await AgoraRTC.createMicrophoneAndCameraTracks();
    localTracks[1].play('local-player');
    await this.client.publish(localTracks);
  }

  ngOnDestroy() {
    this.client.leave();
  }
}

Step 5: Guys Test Your Application

Test your application in a local environment:

ionic serve

Make sure to replace 'YOUR_AGORA_APP_ID' with your actual App ID and properly handle user IDs and channel names for a real-world application. Additionally, ensure that you handle permissions for camera and microphone access, especially on mobile devices.

This basic setup helps you get started with a simple video call application using Ionic 8 and Agora. For production, you would need to handle more scenarios such as network interruptions, multiple users, UI enhancements, and permissions management more robustly.
