Vite changed how we think about frontend development tooling. Instead of bundling everything during development—a process that gets slower as your project grows—Vite serves your source files directly and lets the browser handle module loading.
The result is startup times measured in milliseconds instead of seconds. Make a change, and Hot Module Replacement applies it almost instantly. This speed transforms the development experience, especially on larger codebases where traditional bundlers become painful.
Under the hood, Vite uses esbuild for dependency pre-bundling and Rollup for production builds. You get the best of both: blazing development speed and optimized production output. The plugin system is Rollup-compatible, so the ecosystem of existing plugins largely works.
Configuration is minimal to start. A new Vite project needs almost no setup—sensible defaults handle TypeScript, JSX, CSS modules, and more. When you do need to customize, the configuration is straightforward and well-documented.
Framework support is excellent. Vue (Vite's origin), React, Svelte, and Solid all work well. Starters and templates exist for most combinations, and the frameworks themselves increasingly default to Vite.
The production build story has matured significantly. Tree-shaking, code splitting, and asset optimization all work as expected. For most projects, Vite's output is comparable to webpack in size and performance, with far less configuration.
If you're starting a new frontend project today, Vite is the default choice. Existing projects on webpack can migrate, though the effort varies based on custom configuration.
