Micro-frontends and Progressive Enhancement
What is progressive enhancement?
Progressive enhancement and graceful degradation
So we either implemented graceful degradation, meaning we implemented all the features and then we removed -or blocked somehow the execution with conditionals- of some of the functionality where unsupported, trying to preserve the user experience as much as possible, or progressive enhancement, where we started with the bare minimum to ensure requirements were met, and added enhancements progressively where supported.
We implemented tons of device and agent detection for that -blocking the critical path- ouch!
Today, I feel there is a lot less of that, but I still believe progressive enhancement is a good practice to preserve the user experience, and when it comes to choosing the framework or technology stack for our frontend, thinking of an HTML-first approach, is a good way to go.
