WebRTC practical experience sharing: How to quickly build audio and video call APP?

The importance of embedding voice and video communications in the development of current Internet products is no doubt that WebRTC is in fact a universal technical framework that enables the exchange of arbitrary data streams between browsers without the need for mediation. This enables Web applications and mobile applications to transmit P2P audio/video calls directly without the need for third-party integration.

WebRTC, though titled “Web,” is not limited to the terminal operating environment of traditional Internet applications or browsers. In fact, no matter whether the terminal running environment is a browser, desktop application, mobile device (Android or iOS) or IoT device, as long as the IP connection is reachable and complies with WebRTC specifications, the terminal can communicate with each other. This releases the real-time communication capability of a large number of intelligent terminals (or apps running on intelligent terminals) and opens the imagination space for many application scenarios requiring high real-time interaction, such as online education, video conference, video social networking, remote assistance, remote control and so on, which are suitable application fields.

Back to the scenario of building WebrTC Android, the iOS video chat application uses JavaScript to play a robust and high-performance role in web applications and detect defects in real time. While there are multiple programming languages, databases and operating systems in Linux and Firebase (such as peer-.js, Node.js) are used to build WebRTC video/voice chat applications for Android, IOS, and the Web. Js is the main server-side framework for creating WebRTC signaling server. Let’s take a closer look at the parameters that push JavaScript over other languages.

Why choose JavaScript(Node.js) as the core language rather than some other programming language when building a WebRTC video/voice chat application?

Given that Node.js is the core framework for running JavaScript on the server side, this certainly starts the calling process, and it’s also known as “JavaScript runtime build” — a perfect model for data-intensive real-time applications running across multiple distributed devices. This lightweight and efficient runtime environment is an environment for developing WebRTC video calling mobile applications for Android, IOS, and the Web. Certain parameters attract developers to rely on Node.js to build video chat applications that execute seamlessly on multiple platforms.

#1 Real-Time Web APP:

Where previously low-level sockets and protocols were a real mess for developers, Node.js now offers the added benefit of building real-time Web applications like WebrTC voice/video chat applications at lightning speed and preventing multi-user real-time applications. This event-driven architecture has the potential to allow for absolute, faster synchronization between the server and client, which is written in JavaScript.

# 2Make a request at the same time:

Because Node.js is a compatible server-side framework, it can be configured as a server-side proxy and provides non-blocking IO that can manage a large number of simultaneous connections. In cases where WebRTC video chat applications do not commit too much RAM within the device, the system can process requests simultaneously and queue and execute incoming requests at faster session speeds than other languages such as Python and Ruby.

In addition to developing a WebRTC video chat application, it is also possible to create a video chat application that ends up running very well on Android/iOS&Web by choosing to integrate third parties of video calls into websites/apps and video call integration providers. Here is an advertisement of netease Yunxin seamlessly inserted. Welcome to Netease Yunxin to see the ability to build audio and video calls in 30 minutes.

As a result, WebRTC video chat applications can be built using a variety of programming languages, but only specific languages such as JavaScript can provide the exact video/voice chat application that users expect. In the global WebRTC signaling market, Node.js is the ideal choice to build an ideal WeBRTC-enabled video chat application that delivers superior performance, creates apis, handles concurrent requests, and requires extensibility, To develop a successful WebRTC video/voice chat application for Android, IOS and the Web.
