Run the CLI command ng new and provide the name my-app, as shown here: ng my-app new The initial app project contains a simple Welcome app, which is ready to run. Angular includes a server so that you can easily build and serve your app locally. Now, navigate to the workspace folder (my-app). Launch the server by using the CLI command ng serve, with the –open option. cd my-app
ng serve --open Step 4: Installing chatbot in the Angular component Install chatbot on the angular component. The CLI will create the first Angular component. It is the root component and is named app-root. Run any code editor and open workspace folder (my-app). Note: Components are the fundamental building blocks of Angular applications. They display data on the screen, listen for user input, and take action based on that input. @Component({ : , : , : [ ]
}) {
  title = ;
} selector 'app-root' templateUrl './app.component.html' styleUrls './app.component.css' export class AppComponent 'My First Angular App!'

}) {
  title = ;
  ngOnInit() {
    ( { kommunicateSettings = { : <CONVERSATION_TITLE>};
      var s = document.createElement("script"); s.type = "text/javascript"; s.async = true;
      s.src = "https://api.kommunicate.io/v2/kommunicate.app";
      var h = document.getElementsByTagName("head")[0]; h.appendChild(s);
      (window as any).kommunicate = m; m._globals = kommunicateSettings;
    })(document, (window as any).kommunicate || {});
  }
} selector 'app-root' templateUrl './app.component.html' styleUrls './app.component.scss' export class AppComponent 'my first app' ( ) function d, m var "appId" ,"conversationTitle": < > YOUR_APP_ID The ng serve command launches the server, watches your files and rebuilds the app as you make changes to those files. The –open (or just -o) option automatically opens your browser to . http://localhost:4200/ If you run the browser, you should see a chat widget screen pop up and that means your chatbot is ready.
