Have you ever imagined that your task as a User Interface Developer would one day become that complex? We had to support responsive design, and it was already difficult at some point. Truth is it was only the smallest of our daemons.

It's 2021. We still have to address devices with very non-homogeneous screen sizes, but also very diverse SoC, performance variations, users prefs-based themes, network issues from Edge to 5G or WiFi. And the list will go on growing.

Facing this, we can't continue to handle interfaces the way we did for the last years. We need to shift left, and burn into our Design Systems how to address configurations depending on the context. By moving the responsibility to the components level, we would be able to test, adapt, and deploy at scale complex interfaces without having to fear unexpected issues on some configurations.

Here's how to proceed to build context-proof UI as an Interface Developer in 2021.
