Webpack

Webpack is the industry-standard static module bundler for modern JavaScript applications.

Webpack transforms complex dependency graphs into optimized static assets. It processes JavaScript, CSS, and images through a powerful plugin system (like Babel or MiniCssExtractPlugin) to ensure fast load times and efficient code splitting. By managing over 18 million weekly downloads on NPM, it remains the backbone of the React and Vue ecosystems, providing developers with granular control over asset compilation and environment-specific builds.
