That isn't a thing from Vue3 though. It has come from esbuild and swc projects. Both are now looking to fully support typechecking in a lower level language rather than having JS tooling written solely in JS. You can use vite for React too but it does lack certain features for us. I could get reasonably the same gains using webpack with swc loader or esbuild loader too. It is really just a preference on type of projects. For small starter applications a tool like vite is cool. If you're looking for ways to distribute many common applications with shared vendor libraries and seamless transition between microfrontends then federated modules is a big feature of webpack.
