What Is the Source Code of WhatsApp?

WhatsApp is one of the most popular messaging applications today and has over 1 billion active users worldwide. It is a free, cross-platform messaging and voice-over-IP (VoIP) service owned by Facebook.

The application allows users to send text messages, images, videos, documents and other media over the internet. But what is the source code of WhatsApp?

The source code of WhatsApp consists of two main components: the client application and the server software. The client application is written in a programming language known as Erlang, which is designed for distributed systems. This means that each instance of WhatsApp can run on different servers located around the world and still maintain communication between them.

The server software is written in the PHP programming language and is responsible for handling user requests and data storage. This includes managing user accounts, messages, media files, security protocols, etc. It also contains APIs that allow developers to integrate their applications with WhatsApp so they can access its features from within their own apps.

WhatsApp also uses various open source libraries such as WebRTC and libjingle for video streaming and audio calling respectively. These libraries are used to provide a high quality user experience on both Android and iOS devices.

In addition to this, there are other components such as databases like MySQL or PostgreSQL which are responsible for storing user information like contacts list and messages history etc. All these components together make up the source code of WhatsApp which allows it to function properly as a messaging platform.

To ensure secure communication between users, WhatsApp makes use of encryption protocols like Transport Layer Security (TLS) or Secure Sockets Layer (SSL). These protocols ensure that only authorized people can access your messages or other data shared through the app.

Overall, the source code of WhatsApp is quite complex but it does an excellent job at providing secure communication between users around the world without any disruptions or problems caused by slow internet connection speeds or device compatibility issues.

Conclusion: What Is the Source Code of WhatsApp? The source code of WhatsApp consists of two main components – a client application written in Erlang programming language and a server software written in PHP programming language – along with various open source libraries like WebRTC, libjingle for video streaming & audio calling; databases like MySQL & PostgreSQL for storing user information; & encryption protocols such as TLS & SSL for secure communication between users.
