"Vite (French word for "quick", pronounced /vit/, like "veet") is a build tool that aims to provide a faster and leaner development experience for modern web projects."
Ultimately it makes the dev process more productive because builds are generally much faster than most other build tools.
Ideally, for production you're not constantly rebuilding a JS bundle but instead just building once with all the required package versions and then just serving that bundle all the time.
The bundle only really needs to change if the underlying code does, but in pretty much all cases your customers/users are not actually triggering any changes in your underlying code, that's a security risk.
