babel‑vite is a collection of Babel presets and plugins that mimic Vite‑specific transforms (such as handling `import.meta.env`, `import.meta.glob`, and hot‑module‑replacement) so that code written for Vite can be compiled and run in non‑Vite environments like Node‑based test runners. It’s aimed at developers who need Vite‑style features during development or testing without pulling in the full Vite toolchain.
