How Vite Works
Vite works by utilizing native ES modules and leveraging esbuild for pre-bundling and code splitting on the fly. When running Vite in development mode, it serves the code directly to the browser using the import/export syntax supported by modern browsers. This eliminates the need for repeated bundling and transpiling, which can slow down the development process.
In production, Vite uses Rollup, a module bundler, to bundle the files. Rollup ensures that the final output is optimized and ready for deployment. The combination of esbuild and Rollup allows Vite to provide both efficient development and optimized production builds.
