Building Your Own Group Voice Calling Application Using the Agora Web SDK

In this tutorial, we will develop a web application that supports voice calling among multiple users using the Agora Web SDK. The prerequisites for this project include basic knowledge of JavaScript, JQuery, Bootstrap, Font Awesome, an Agora developer account, and the Agora Web SDK. We begin by setting up the HTML structure with necessary UI elements such as buttons for joining, leaving, muting, and unmuting audio streams. Then we add custom CSS to match the site with a blue Agora-based theme. The core functionality is implemented using JavaScript, which uses the Agora Web SDK to create clients, microphone audio tracks, and handle user interactions such as joining, leaving, and muting/unmuting audio streams. Finally, we test the application by running it in multiple browser tabs to simulate multiple users on the call. The finished code is available on GitHub, and a demo of the code in action can be found at https://agora-voice-calling.netlify.app/.
