STOP Using Extensions for Mapping! | Clean Architecture

In this video, I explain why using extension functions for mapping data layer models to domain layer models is not a best practice and how it can harm your project's scalability and maintainability. Learn clean architecture principles and discover the right way to handle model mapping using dedicated mapper classes. If you're striving for clean code and better separation of concerns, this video is a must-watch! Stick around to level up your Android development skills and create more robust and scalable apps.

📌 What you’ll learn:
✅ Problems with extension function mapping
✅ Benefits of using mapper classes
✅ Clean architecture mapping strategies
✅ Practical examples and best practices

I’ve always used mapper interfaces in my projects, but I was about to switch to mapper extension functions. Thanks for making this video—it saves me a lot of time and headaches!

I like the topic and good video but i think it could have been slightly more streamlined. The first 5 minutes I ended up just watching boilerplate of writing a data class. But keep it up look forward to more!

Hi,

If there are 300 models then still need to create 300 mapper.

You created generic function a -> b type mapper.

Bro, why are you saying you are going to test the failure scenario, but end up testing the success one and blaming on the extension? This video makes zero sense.
