Parcel

Parcel is a zero-configuration build tool that automates asset bundling with out-of-the-box support for JS, CSS, and HTML.

Parcel eliminates the overhead of manual configuration files like webpack.config.js by using a convention-over-configuration model. It leverages a multi-core worker process to parallelize compilation and utilizes a persistent file system cache for instant subsequent builds. Developers get high-performance features (including Hot Module Replacement, tree shaking, and image optimization) immediately upon installation. It handles everything from TypeScript and React to PostCSS and SVGs without requiring custom plugins for standard web development workflows.
