What Parcel is

Parcel is a free, open-source build tool for web projects that works with many file types without requiring initial configuration. It handles HTML, CSS, JavaScript, TypeScript, JSX, Flow, images, fonts, video, Sass, SVG, Vue, Node, Electron, GraphQL, MDX and XML, and can install plugins and development dependencies for other file types. Its development server includes HTTPS and an API proxy, and browser updates integrate with React Fast Refresh and Vue hot reloading. Diagnostics appear in the terminal and browser with highlighted code, hints and documentation links. For builds, Parcel uses worker threads, caching and lazy development builds; production options include tree shaking, minification, image optimization, code splitting and content hashing. It can transform code for declared browser targets, build workers and libraries for multiple targets, and build monorepos. A plugin system and programmatic API support customization and integration with other build systems. The free plan is available. The development server builds one target at a time and defaults to a modern browser target; compression is supported but not enabled by default.
