We recently migrated a Laravel app from Webpack (Laravel Mix) to Vite and it was mostly painless. Like OP, we had to update some imports that were using require and we also have a few different entrypoints which is not that well documented for the Laravel plugin. Another issue we ran into was certain dependencies that only have .cjs versions that work fine when building, but during dev would fail to import via ESM correctly (the dependency itself is inside of a lazy loaded component). That means that if we're working on that part of the app, we need to do a full production build (6 seconds) between each code change and then use the prod build locally to test the feature. Annoying for sure but we can live with it until someone has time to update the dependency to one that natively supports being loaded via ESM. If anyone is running the old Laravel build pipeline, I suggest upgrading now because it's potentially only going to get more and more complicated. If you have a simple frontend with some helper functions or a few Vue components, it should be pretty easy to reason about. The course on Vite from Laracasts was helpful to explain what some of the less documented features are, which was helpful for integrating with our application.
