Vite: Does Vite support CommonJS dependencies?

Vite automatically converts CommonJS dependencies to ES modules during pre-bundling using esbuild, but it does not support Node.js built-in polyfills. For projects requiring Node builtins, additional configuration may be needed.

Source
GNAT Pro: What is GNAT Pro licensing model?

GNAT Pro is sold on a per-user, per-year basis with no license locks. Customers can request pricing for their specific needs.

Vite: Can Vite work offline?

Vite requires internet for initial dependency pre-bundling with esbuild. Once dependencies are pre-bundled and cached, development can continue with local file serving, but full offline development is not supported.

Source
Vite: What are Vite's system requirements on Windows?

Vite can run on Windows, but WSL2 users may experience file watching issues where Vite cannot detect file changes in certain conditions. Windows users with project paths containing ampersands may encounter module resolution failures with npm.

Source
Vite: Does Vite support TypeScript, JSX, and CSS out of the box?

Yes. Vite natively supports TypeScript, JSX, CSS, and WebAssembly without additional configuration needed for basic use.
