Development stack and Architecture


We have written our own module for audio and video calls, which works on WebRTC, It also integrate in native applications code. A distributed signal server is also written from scratch. It allows you to create large audio and video conferences. You do not need to pay for the services of providers, it is free.


Used technologies: NodeJS, TypeScript, GraphQL, Redis, MongoDB. All resolvers typed. All database queries are optimized and built on aggregation. Socket server designed as a separate microservice, this allows to replicate it.

Mobile Apps 

Apps written on TypeScript, React Native version 0.61.5 and Expo (Bare workflow) version 37.0.10. For state management used Apollo Cache. For data types used GraphQL Code Generator.

Web App

Web is developed on TypeScript and React. For routing used react-router. Some components are reused using react-native-web. For styles using linaria. Also, all lists are virtualized and optimized for performance.

Desktop Apps

Desktop applications work on Electron. All applications are created with one command. Also, optimization was performed for each of the available platforms.

Optimized code

You do not need to get involved with code performance. Many components are optimized for performance. The server part is easily scalable even on weak hardware, which saves resources. Many components and logic can be reused. Based on this product, there is everything to quickly start making any functionality.

Who is it for?

This is a quick start for any team. Those who need to move fast understand the value. And those who worked in large distributed teams understand the value of a well-built architecture.

There are no boundaries for ideas

This item for sale is a ready-made cross-platform product with a more complex architecture that includes four independent applications designed for high loads and optimized for weak server hardware, which saves resources in the long term.

How can the buyer take this project further?

This product will be of interest to those who want to quickly implement messenger features in their product or launch a ready-made messenger immediately. This implies that the buyer either has its development team or has the capabilities and resources for one or more developers to maintain the code.It is a full-fledged cross-platform messenger with audio and video calls and built-in streaming service. 

For example, some development teams may adopt The WebRTC audio and video call module and implement this feature in their applications. Or, the company will want to make a payment messenger from the messenger, integrate the capabilities of a mobile wallet into it, or you can make it a crypto messenger by enabling support for blockchain and transactions. Those who already use such a stack of technologies can also easily implement the messenger in their application or system, for example, in a CRM system. It turns out that it is for ideas-there are no borders, it all depends on your tasks. You can use the code for mass use, such as streaming services, payment messengers, etc., or you can use it for a specific niche, for example, as a corporate messenger and offer this solution to the market. 

We made this code for ourselves, so it is adapted and built professionally. At the moment, we simply do not have time to develop this direction, because the team is focused on a large project on financial markets, so we have to invest all our financial and labor resources in a project on financial markets. Or adapt the code to suit your business, it all depends on your goals and interests.
