These are what you will require:

Node.JS: Visit the official Node.JS website to download Node.
NPM: This program gets installed on your PC right after installing Node.JS.
Project Establishment

Build an empty directory named video-chat-app.

Unfold your console, move to the brand-new directory, and run npminit.
To initialise your project, provide adequate information.
Within the video-chat-app directory, run npm install express ejs socket.io uuid peer. Once done, it will install the dependency, which we require to create this app.

WebRTC
WebRTC is a well-known tech in video chat application making from a technology standpoint. It’s an open-source internet protocol that helps users make videos in real-time using straightforward APIs. The great tech is used to establish and perform a peer-to-peer connection; without the guidance of a top-notch web server from a third party. This is how WebRTC will keep on submitting media content. In brief, WebRTC can effectively be used together with four APIs, which are the following:

**RTC DataChannel**
It offers a peer-to-peer communication network for data generalisation.

**MediaStream**

This one allows chatting between clients using either a video camera or a microphone.

**OpenTOK**

Although it’s not a specific API, an open-source library and PaaS platform can be used to authorise cross-platform video chats.
**RTCPeerConnection**

This API is liable for the protection of video chats, as it authorizes video and audio data transfer with top-notch access control and encryption support.

**Where can we use WebRTC technology?**
A wide array of fascinating use cases exist for WebRTC. The best utilisations are shown below:

**Broadcasting**

WebRTC can be utilised to distribute single-way media transmissions, for example, speeches, videos, podcasts, and concerts. In addition, users can acquire a real-time solution, such as attendance information, with the help of a solution, PubNub.
**Audio Calling**

The audio and video in WebRTC work seamlessly by using codecs, which are well-known algorithms used to compress and decompress audio and video data. Moreover, Ficode has previous experience integrating audio calling in web and mobile applications. That’s why with the help of WebRTC, our developers can build the best video chat app.

**Share screen**
Sharing screen is another use case of WebRTC technology, which helps you get explicit notions about the work and its outcomes. After Ficode’s involvement in making seamless video chat apps with WebRTC technology for your business, you can see your sales reps grow.
Node.JS
The most significant benefits of choosing Node.Js for real-time video chat application development projects are the following:

A Node.Js framework is renowned for its event-driven competency, making it hassle-free for Ficode’s web developers to track I/O bound tasks. Also, its streams are UNIX-based and that’s why the framework can be read clearly and decode the input from its source and send it back to its original destination.
By selecting Node.JS to create a video chat app, the developers can ensure straightforward data transfer between the server and client. Also, this server can make sure data readability and transferability between the server and client.
Where can we use Node.JS technology?
