Everything You Need to Know About WebRTC App Development

WebRTC is a browser technology that uses point-to-point transmission to convey streaming data between browsers or apps.

This technology is appealing since it enables you to connect with consumers using nothing more than a browser. When many developers hear about WebRTC, it is a revelation: you can construct a video chat without requiring a third-party server; all you need is a browser – and this is fantastic!


WebRTC requires no extra plug-ins to be installed. Simply write the code in JavaScript, and the video streams will play nicely in the browser.


WebRTC may be used for more than just video conversations; the technology can also be used to transmit files of any kind and text communications. If you need a solution based on this platform, check out webrtc mobile app development services.



WebRTC provides a rather extensive collection of features and tools. We will go through the three APIs of this technology.



You may manage user devices using the API from a browser. You have the following options:

  • a camera that will be used to transmit the footage;
  • the microphone;
  • the transmitted image’s quality.


These options aid in project optimization. A high-quality picture might be reduced to 360 pixels for faster work. Users no longer have to rely on device settings since they may establish their own quality restrictions.


The noise control method also contributes significantly: it successfully removes noise and background noises from an audio stream.



This API is based on peer-to-peer (P2P) technology, which is a direct combination of two browsers that do not rely on a server. As a result, video feeds are transferred directly from one device to another.


Inside the RTCPeerConnection is a crucial feature: built-in support for Stun/Turn servers, which are required to circumvent the NAT provider, without which video streams may not reach viewers.


Developers may connect to Stun/Turn servers as a single user to get a clean address for transmitting a video stream. You may then rejoin to Stun/Turn servers from another user. Failures and issues with user connections caused by NAT technology are avoided in this manner.



Text and files of different forms may be sent in tandem with the video stream using RTCDataChannel.


You may use this API to create a basic and quick chat for application users. It does not need server installation, may be rebuilt, and can transmit data of any type up to 4 GB in size (and more, if a browser allows it).


Migration from Flash to WebRTC

Flash technology is becoming obsolete and will be phased out over time. It has not been updated and will be deleted from the browser shortly. As a result, it is critical to migrate Flash-based applications to alternative technologies, such as WebRTC.


WebRTC enables you to display videos in handy players in the form of video files or live streams, as well as transmit files and text messages of any type. Furthermore, it is a new, optimized technology with several internal options that does not need the installation of extra servers or plug-ins.


WebRTC is not a substitute for Flash. WebRTC is a technology that allows you to partly implement Flash capabilities.


Technical difficulties

WebRTC technology has its drawbacks.


TCP and UDP are the network protocols used by WebRTC

The TCP protocol is unique in that it transfers data without loss: the user gets a steady picture with no loss or damage. However, this protocol has data transmission limits. You cannot, for example, send a Full HD video to five individuals at the same time.


The UDP protocol solves this issue. It allows users to send high-quality photographs and 

videos without restriction. However, this protocol has a disadvantage: it allows for packet loss. The transferred file is quite likely to be damaged: the picture may wobble, pixels may be seen, and so on.


This disadvantage may be mitigated by connecting to third-party services. If you are developing a large-scale WebRTC project that will connect hundreds of people, you will need to deploy an extra server to alleviate the burden on the browser.


Which projects are most suited to WebRTC?

Initially, WebRTC was intended to establish video conferencing utilizing peer-to-peer technology without the need for a server. As a result, the technology is well suited for browser-based video conferencing. This is a full-featured Skype capability contained inside a single browser.
