Hello,
Before starting, this is ionic 5 angular 9 simple example of video call.
At the end you can connect two device in same network if the app is running on both of them.
if you want to wake up the app first you have to use something like push notification, we don't implement it now.
let do it fast :D
ionic must be installed.
from your console run
ionic start ionic-peer blank
then inside of your project folder, get peerjs:
npm install peerjs --save
add esModuleInterop to your tsconfig.json as below:
"compilerOptions": {
....
"esModuleInterop": true,
....
}
create peer service:
ionic generate service providers/webrtc
edit WebrtcService, it'll initiate peer-to-peer connection and make call.
import Peer from 'peerjs';
export class WebrtcService {
peer: Peer;
myStream: MediaStream;
myEl: HTMLMediaElement;
partnerEl: HTMLMediaElement;
stun = 'stun.l.google.com:19302';
mediaConnection: Peer.MediaConnection;
options: Peer.PeerJSOption;
stunServer: RTCIceServer = {
urls: 'stun:' + this.stun,
};
constructor() {
this.options = { // not used, by default it'll use peerjs server
key: 'cd1ft79ro8g833di',
debug: 3
};
}
getMedia() {
navigator.getUserMedia({ audio: true, video: true }, (stream) => {
this.handleSuccess(stream);
}, (error) => {
this.handleError(error);
});
}
async init(userId: string, myEl: HTMLMediaElement, partnerEl: HTMLMediaElement) {
this.myEl = myEl;
this.partnerEl = partnerEl;
try {
this.getMedia();
} catch (e) {
this.handleError(e);
}
await this.createPeer(userId);
}
async createPeer(userId: string) {
this.peer = new Peer(userId);
this.peer.on('open', () => {
this.wait();
});
}
call(partnerId: string) {
const call = this.peer.call(partnerId, this.myStream);
call.on('stream', (stream) => {
this.partnerEl.srcObject = stream;
});
}
wait() {
this.peer.on('call', (call) => {
call.answer(this.myStream);
call.on('stream', (stream) => {
this.partnerEl.srcObject = stream;
});
});
}
handleSuccess(stream: MediaStream) {
this.myStream = stream;
this.myEl.srcObject = stream;
}
handleError(error: any) {
if (error.name === 'ConstraintNotSatisfiedError') {
const v = constraints.video;
// this.errorMsg(`The resolution ${v.width.exact}x${v.height.exact} px is not supported by your device.`);
this.errorMsg(`The resolution px is not supported by your device.`);
} else if (error.name === 'PermissionDeniedError') {
this.errorMsg('Permissions have not been granted to use your camera and ' +
'microphone, you need to allow the page access to your devices in ' +
'order for the demo to work.');
}
this.errorMsg(`getUserMedia error: ${error.name}`, error);
}
errorMsg(msg: string, error?: any) {
const errorElement = document.querySelector('#errorMsg');
errorElement.innerHTML += `<p>${msg}</p>`;
if (typeof error !== 'undefined') {
console.error(error);
}
}
}
init method will create a peer connection with yourId and then register wait method to listen to any call .
if any call receive inside wait method, it'll answer the call automatically,
you can handel it by yourself
(new peer() without option will connect to default server, you can use other server or run your own peer server)
it'll also start to stream video/audio as you define in option and push it to object of html element.(we have to create a html element to show video in home.html page)
call method will ask peer server to connect you to your partner as call type.
both call method and wait method duty is streaming partner video/audio and show it inside of partner media frame(we will create it inside home page)
Edit home.html
<ion-content>
<div id="errorMsg"></div>
<video id="partner-video" (click)="swapVideo('my-video')" autoplay playsinline
[ngClass]="{'top-video': topVideoFrame === 'partner-video', 'main-video': topVideoFrame != 'partner-video'}">
</video>
<video id="my-video" (click)="swapVideo('partner-video')" autoplay playsinline
[ngClass]="{'top-video': topVideoFrame === 'my-video', 'main-video': topVideoFrame != 'my-video'}" >
</video>
<ion-row nowrap>
<ion-button (click)="init()">Login As: </ion-button>
<ion-item>
<ion-input type="text" [(ngModel)]="userId" placeholder="enter your nick name"></ion-input>
</ion-item>
</ion-row>
<ion-row nowrap>
<ion-button (click)="call()">Call To: </ion-button>
<ion-item>
<ion-input type="text" [(ngModel)]="partnerId" placeholder="your partner nick name"></ion-input>
</ion-item>
</ion-row>
</ion-content>
video tag will show you stream media of you and your partner.
you have to login with nick name, because of using default server, you may see other people with easy nick name :D
Edit home.ts like this
import { WebrtcService } from '../providers/webrtc.service';
export class HomePage {
topVideoFrame = 'partner-video';
userId: string;
partnerId: string;
myEl: HTMLMediaElement;
partnerEl: HTMLMediaElement;
constructor(
public webRTC: WebrtcService,
public elRef: ElementRef
) {}
init() {
this.myEl = this.elRef.nativeElement.querySelector('#my-video');
this.partnerEl = this.elRef.nativeElement.querySelector('#partner-video');
this.webRTC.init(this.userId, this.myEl, this.partnerEl);
}
call() {
this.webRTC.call(this.partnerId);
this.swapVideo('my-video');
}
swapVideo(topVideo: string) {
this.topVideoFrame = topVideo;
}
}
login method will assign video frame to html element and pass them to webrtcservice, so the service can push stream to them.
call method will pass partnerId to webrtc service for connection to your partner.
Edit home.scss
.top-video{
position: absolute;
top: 100px;
right: 100px;
max-width: 100px;
z-index: 2;
}
.main-video{
width: 100%;
max-height: 70%;
}
after you and your partner get connected, you can swap video with swapVideo method and [ngClass].
webrtc service will ask for camera/microphone permission.
because of that, when we run application outside of localhost, browser will block permission, so we have to run it with --ssl parameter.
first join your pc/laptop with your second device (pc/laptop or mobile) to the same network
then run ionic serve with your ip address, for example:
ionic serve --address 192.168.43.105 --ssl
in your second device visit that address with https prefix:
https://192.168.43.105:8100

Hi, Can you please guide me how do i connect video call from two different network. Your code only work if app is connected to same network.
Ofc, As i said you need turn server to establish a connection.
Look at coturn project on github.
run it on linux or first instal wsl in windwos and run it from wsl.
Do you have any server which i can use in my code?
No mate, i dont have free public turn server.
It's just for client.
But why u not try to run it.
Just follow coturn repository from github, Run it from linux or as i said just install wsl on windows and then you can run linux from shell
Hello, Can you help me?
Can I make this project workable with firebase?
Yes it is posible, You just need a signaling server and maybe turn server. There is an opensource turn server called coturn
if possible please let me show how it actually works in ionic 5 app
Ofcorse mate
sir i am trying it in my new ionic 5 application but can not create any type of connection please help me to short out the problem if possible
Need to look at your code or at least tell me what you are trying to do.
Hi this is awesome, i'm building an app based on your tutorial. i currently want to add some functionality like waiting for an answer, and also automatic destroy both user.
i also posting on stackoverflow stackoverflow.com/questions/672497..., if you got time pls help me there. thanks
I'm glad to hear that, I implemented video call in a real app and for that, I used simple-peer instead of peerJs.
I had no time to write about my new experience, also in the real app I found we will need a turn server to work when clients are not in the same network.
For turn server i used this repository:
github.com/coturn/coturn
run it in Linux. (for windows os use WSL)
wow thats great, so do you prefer simple peer instead of peerjs? cause i got problems with listening an event if someone on the other side click a button or something. they said to use socket.io, but i dontwanna use that
Yes simplepeer was better for me,
for socket i used signalr in dot net core.
using hubconnection
you can use any other language as your signaling server line nodjs, java, python etc...
great!! but do you have any suggestion on listening to an event that someone on the other side fire an event? like closing or destroying the connection? i can show you my code if you could help me out
Calling peer close() function in frontend side must work and As I said, From backend you can call hubconnection methods in signalr dotnet core
for other language i dont know
actually i use peerjs cloud server, so i only working on front end. Is using my own peerjs server a must?
peerjs server is just for signaling, (both clients will create some signale and send them to each other with server)
you can implement signaling server in any language.
but for your priblem to alter other client to close the connection it must work. I don't know why close() function not triggered.
maybe you have to look at peerjs document.
yeah what i wrote was following the peerjs docs, i post an issue on their repo. Thanks for your help, hope you'll share more knowledge
Awesome Bro.
How can I disconnect the camera and signaling server connections?. I tried this.peer.close() but it's not working. Can you please help me to sort out this.
I don't remember, but you can stop video stream. play() stop()
also hide the video element
Is it possible to record the video call?
Hello,
Is it possible to record the video call?
Thanks
I didn't try it but it can be posible
If that can help someone, i created a proof of concept using peersjs with ionic capacitor thanks to the work of @timsar2 .

Enjoy
