Big shout out to @KTanAug21 for this article https://fly.io/laravel-bytes/multi-file-upload-livewire/. I recently needed to be able to allow my users to upload files using Livewire and this article helped me tremendously in building what I needed.
I needed a drag and drop image upload solution using Laravel Livewire. So using the above article I built one that allows concurrent, chunked, file uploads. But I took it a step further and implemented drag and drop functionality along with validation on the client side.
