WebRTC has taken over internet calls, making it the onus of communication. WebRTC enables web application and mobile applications to stream peer-to-peer audio/video calls directly without the requirement of third-party integration. Though there are multiple other languages to build WebRTC, such as peer.js, node.js, in Linux and Firebase, JavaScript rules out all the other programs with its phenomenal features. Let us take a close look at the parameters that pushes JavaScript over other languages. Every other webRTC signaling server has the potential to build a cross-platform chat app that works on android/iOS. The short span of time JavaScript/node.js consumes to design a multi-user real-time application holds high potential to synchronize with the requirements the client delegates. WebRTC video chat apps can be loaded as a server-side proxy and offers non-blocking IO, a set of features that can handle towering numbers of connections simultaneously. The system will not occupy excessive RAM space with video calls allowing a large number of calls to take place on the go. Creating a video chat app using android/iOS javascript does not stop with providing video-voice internet calls through apps. The community is also growing up to provide exceptional modules that are absolutely ideal for integration of video call into the website and mobile applications. Socket.io is used to manage the constant communication between both the servers to provide real-time updates on the go. Apart from building WebRTC for video chat app, opting for a third party integration of video call into website/app and video calling integration providers has the potential to create a peerless video chat app that runs on Android/iOS or Web - any platform of your choice. Contus Fly is a readymade messaging SDK for Android & iOS, Chat API for Website, WebRTC solution provider, that has over a decade of experience in building chat apps.

Chat App using WebRTC?

2. What is WebRTC?
● WebRTC is an open source code that was created to deliver low
cost, high quality audio and video communication. The source
code is, at present, owned by Google.
● Most enterprise voice/video calls use signalling server. However
there are 2 other servers - STUN & TURN in WebRTC.
● Unlike signalling server, STUN & TURN servers are not open
source scripts.
● STUN is used to make calls between two different networks, while
TURN servers are designed to connect past proxy firewalls in
networks.

4. Node.JS in WebRTC
● Unlike the traditional server side scripts that works through
single channel when multiple users attempt to make calls, node.js
offers parallel channeling, thus, eliminating the time lag which
often occur in VOIP calls.
● Real time peer to peer communication across NATs in WebRTC
is simplified through node.js

6. WebRTC Synchronisation
● Client and server side synchronization allows users to stream
audio/video on browsers without any plugins.
● Generally, WebRTC does not record the media exchanged
through it. However, these media can be recorded at 3
premises if need arises. They are server side, Client side and
Media forwarding.
