Business Challenge

In the modern world, we have to solve various questions and complete a lot of different tasks. All this is impossible without clear communication between different people every day. The peer-to-peer video chat web application should be created to facilitate and accelerate communication process between employees, help them communicate with each other faster and more efficiently via chatting rather than emailing.

The customer’s company requested to develop an easy-to-use peer-to-peer application with a secure video/audio, file sharing and text messaging possibility for inside communication among its employees. The main purpose of the application is to make communication between different offices of the company easier, quicker and more efficient. The key functionality was to include group and peer-to-peer chatting and video/audio communication without internet access. The stand-alone peer-to-peer video chat application should ensure high security, high working stability and high quality of audio and video streams for up to 5 peer-to-peer connections at a time. The web application should give a possibility for creation of chatting groups to up to 3000 users. The video chat should operate on desktop devices (PCs and laptops) only. The customer required a dynamic, easy-to-use and informative peer-to-peer video application to accelerate and facilitate inside processes of communication between employees and offices of the company.

XB Software team was required to develop an efficient and stable corporate stand-alone peer-to-peer video application which should operate without the internet connection. The development team represented by a business analyst, WebRTC and React developers, as well as QA engineers, was responsible for the creating the bug-free code of the web application.

To guarantee the high security of inside communications via the application we applied WebRTC technology. WebRTC security is enabled by standardized encryption methods that have been proven to protect users from unwanted entrance into their private information. Its standards offer excellent protection in addition to the revolutionary streaming voice and video features that define the technology.

The front-end of the peer-to-peer video chat application was implemented using React.JS and CSS, which helped to create the user-friendly design and clear features of the app. The back-end of the app was made using Node.js and MySQL. Other technologies applied include Redux, Docker, Redis, Nginx.

XB Software’s developers created the peer-to-peer video application with the next features: persistent and fast connection/disconnection via video or audio, text messaging, group or private possibility of communication and the use of general alerts when an event of employee’s interest happens. Users can share their images, documents using file sharing feature.

Peer-to-peer communication and group chatting in a private chat were enabled. Private video/audio calls allowed adding up to 3000 users to chat conversation (text messaging) and up to 5 users for a video/audio call. If a user wants to talk one to one to a person from the conversation, he’ll need to create a new one to one chat using search. Moreover, all the users have to be authenticated in the web application to be able to perform any operations.
