At this point yes. I'm sure there are still some things that you will need Webpack for, but in my experience I have yet to find one of those instances. Vite is not just way way way faster than Webpack, it's also way simpler.
Configuring a React project from scratch with Webpack is an undertaking, especially if you're not seasoned with Webpack configurations. Vite on the other hand is super simple to setup, I typically don't even reach for the starters that vite offers because it's just as easy to do an `npm init -y` and then install it manually.
I work for a web dev agency and we have migrated all of our existing projects to Vite, and advised any new projects to not use Webpack unless there is a very specific reason and other solutions have been exhausted.
