How often have you needed to modernize a legacy frontend application and re-build them using a more modern technology/framework like React/Angular etc.?<p>At my current job, I have to migrate a JQuery dashboard to React. I was wondering what other people's experience has been in this regard.<p>What were some of the pitfalls that I should look out for?<p>If you ever had to do it, what was the most painful part of this migration?
It's a fairly common task in my experience. Focus on converting one component at a time and it should go smoothly. Don't try to do a complete rewrite at once.
Using React, an incremental re-write is pretty easy, since it can be plugged in for certain components as they become available. Slowly re-write components in React as you modify them, and always write new components in React. Not sure about Vue, but I believe it's the same.
