How WhatsApp Was Coded?

WhatsApp is a popular messaging app used by millions of users around the world. The application has been around since 2009 and it continues to be one of the most widely used messaging apps available. But have you ever wondered how WhatsApp was coded?

The coding process for WhatsApp began with the development of an open source cross-platform messaging framework called XMPP (Extensible Messaging and Presence Protocol). XMPP was developed by the Jabber Software Foundation in 2002 and is used by many different communication services.

This framework is capable of sending text, audio, video, images, and other data over a network. Using this framework as a starting point allowed WhatsApp to create its own custom messaging system.

Once the basic XMPP framework was in place, the developers at WhatsApp began adding additional features to make their messaging system more robust. They added encryption protocols so that messages could be securely sent between users without anyone being able to intercept them.

They also included multimedia support so that users could share photos, videos, and other files with one another. These features were all coded using various programming languages such as JavaScript, HTML5, Objective-C, and Java.

In addition to these core features, WhatsApp also created its own APIs (Application Programming Interfaces) which allow developers to create third-party applications that can interact with the service. This means that developers can create their own custom applications for use with WhatsApp such as chatbots or automated customer service systems.

Overall, coding for WhatsApp has been an ongoing process since its inception in 2009. The initial development of an XMPP-based messaging framework allowed for the creation of a secure and reliable platform upon which further features could be built. From there, developers have continually worked on adding new features such as encryption protocols and multimedia support while also creating APIs so that third-party applications can be created.

Conclusion: Coding for WhatsApp has been a complex process due to its large user base and wide range of features. By leveraging existing frameworks such as XMPP while also creating their own APIs, the developers at WhatsApp have been able to create a powerful messaging platform that is versatile enough to meet the needs of millions of users around the world.
