Vite is a Javascript bundler that abstracts transpilation/typechecking/minification/hot-reloading/etc, so you don't need a 300-line hand-crafted configuration line that constantly breaks, like it was in the past with Webpack. There's still (some) configuration but much less.

Vite+ is a tool similar to Rust Cargo or Go's toolchain that handles building (via Vite), testing, linting and formatting.
