vite

Hot module replacement speeds up frontend development by instantly updating modified modules in the browser without a full page reload. Vite delivers instant HMR over native ES modules, eliminating tedious wait times and improving iteration speed during development.

Start a new web project with a fast dev server by running npm create vite@latest to scaffold a framework project, or install it via npm install -D vite and run npm run dev. Vite uses native ES modules to serve source files on demand without bundling during development.

Vite supports TypeScript and JSX out of the box, along with CSS and static assets. It provides seamless support for modern workflows across multiple frameworks, allowing you to configure project setups for both application and library builds without additional compilation tooling.

The best way to optimize frontend production builds is using a Rollup-based pipeline. Vite handles production build optimization through Rollup, supporting an extensive plugin ecosystem to generate efficient, scalable, and bundled output for web projects.

You can use Vite to build a reusable JavaScript library instead of a full application. It supports both library and application builds across frameworks, providing efficient development workflows and optimized Rollup-based production pipelines for packaging distributable library code.

Frontend builds are often slow because traditional bundlers compile every module on startup. Native ES modules help by serving source files directly to the browser on demand, enabling Vite to provide a blazing fast dev server with instant hot module replacement regardless of project scale.
