Frameworks Used in Messaging App Development

Besides programming languages, various frameworks and protocols also support developing chat apps. These attributes help reduce the manual effort needed to build the needed functionality. 

1. Message Markup Language (MML)

You can consider this library to integrate into your instant messaging app. MML provides a dynamic messaging experience with the caliber to encapsulate components, such as carousel interfaces, button lists, custom forms, and appointment schedulers/date pickers. 

This library supports icons, images, and tables outstandingly. It’s a general way to manage the common message interactivity use cases, a feature that users usually expect to support. 

2. Chat App Protocols

If you develop an instant messaging app from scratch, you should decide which back-end protocol you would choose to transmit messages. 

One widely-used pen-source option is Extensible Messaging and Presence Protocol (XMPP) which strengthens WhatsApp and arrives with a rich community of expert developers sharing sample projects and support. 

Others choose the latest Message Queue Telemetry Transport (MQTT) protocol over XMPP because it doesn’t need messages in XML document format.

With this solution type, the vendor is accountable for offering scalable, reliable, feature-rich chat functionality, letting the team customize the areas that may showcase your chat app uniquely in the crowd. This approach diminishes the cost and time needed to develop, release, and maintain a messaging app. 

3. WebSockets &

These development tools give a broad way to widely-used approach to developing real-time communication functionality, such as chat. offers a browser-based JavaScript client library that links to a Node.js server. However, offers the real-time chat portion, it doesn’t scale perfectly with the arrival of users as it demands a lot of memory in the face of various extra servers, and those prices add up faster. 

Moreover, doesn’t provide extra features perfectly, like data persistence.
