Creating video chat application in Angular 17

Creating video chat application in Angular 17

Creating a video chat application in Angular 17 involves several steps, including setting up the Angular project, integrating WebRTC for peer-to-peer communication, and potentially using a signaling server for coordinating communication. Below, I’ll outline a basic approach to get you started on this project. This guide assumes you have a basic understanding of Angular and TypeScript.

Step 1: Set Up Angular Project

First, make sure you have Node.js and the Angular CLI installed. Then, create a new Angular project:

ng new video-chat-app
cd video-chat-app

Step 2: Add Angular Material

Angular Material provides components that you can use to build the UI quickly.

ng add @angular/material

Choose a theme and set up global typography and animations when prompted.

Step 3: Generate Components

Generate components for the video chat application:

ng generate component home
ng generate component video-room

Step 4: Install PeerJS

PeerJS simplifies WebRTC peer-to-peer data, video, and audio calls. Install PeerJS:

npm install peerjs

Step 5: Configure Routing

Set up routing in app-routing.module.ts to navigate between the home component and the video room:

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { HomeComponent } from './home/home.component';
import { VideoRoomComponent } from './video-room/video-room.component';

const routes: Routes = [
  { path: '', component: HomeComponent },
  { path: 'room/:id', component: VideoRoomComponent }

  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
export class AppRoutingModule { }

Step 6: Implement Video Room Component

In video-room.component.ts, use PeerJS to create a peer and handle incoming video calls. This is a simplified example:

import { Component, OnInit, OnDestroy } from '@angular/core';
import Peer from 'peerjs';

  selector: 'app-video-room',
  templateUrl: './video-room.component.html',
  styleUrls: ['./video-room.component.css']
export class VideoRoomComponent implements OnInit, OnDestroy {
  peer: Peer;
  myStream: MediaStream;
  myEl: HTMLVideoElement;
  partnerEl: HTMLVideoElement;

  ngOnInit() {
    this.myEl = document.getElementById('my-video') as HTMLVideoElement;
    this.partnerEl = document.getElementById('partner-video') as HTMLVideoElement;

    navigator.mediaDevices.getUserMedia({ video: true, audio: true })
      .then(stream => {
        this.myStream = stream;
        this.myEl.srcObject = stream;

        this.peer = new Peer(undefined, {
          // Specify your PeerJS server here

        this.peer.on('call', call => {
          call.on('stream', stream => {
            this.partnerEl.srcObject = stream;

        // Generate peer ID and make a call if there's another peer ID available

  ngOnDestroy() {

Step 7: Handle Peer Connections and Calls

Expand on the VideoRoomComponent to handle making and answering calls, which involves generating unique room IDs and sharing them for peer connections.

Step 8: Build and Serve the Application

Finally, build and serve your Angular application:

ng serve

Visit http://localhost:4200/ in your browser to see the application.


  • Implementing a full-featured video chat application requires handling more details, including signaling to exchange peer information (possibly using a backend service or Firebase for signaling), managing call state, and ensuring privacy and security in communications.
  • You might need to deploy a STUN/TURN server for production use to handle NAT traversal and firewall issues, ensuring users can connect with each other under various network conditions.

This guide gives you a starting point. Depending on your requirements, you may need to expand your application with additional features and robust error handling.
