In this episode, we tackle a usability issue that popped up when importing CSV files: after importing, a bunch of data—including the uploaded file, column mappings, and other details—was sticking around in our component's state when it shouldn't be. This meant if you wanted to import another file immediately, you'd see old bits of info hanging around, which isn't ideal.
To fix this, we dive into our CSV Importer component and implement a smart reset for its properties. Instead of resetting everything, we selectively keep the stuff we don't want to reset (like the columns to map, required columns, column labels, and whether the modal is open) so the component still behaves as expected. We use Livewire's resetExcept()
method to clean up just the right values after an import, ensuring everything goes back to its initial state for a smooth repeat import experience.
Finally, we try out the new flow: importing one file, then another, showing how the cleanup works, and explaining why we might or might not want to reset certain bits of state. It keeps things neat and avoids confusion for users doing back-to-back imports!
