About this project

Bundlephobia is a frontend development tool for evaluating the cost of including an npm package in an application bundle. It supports ES6 packages and can build CSS and SCSS packages in beta. Results include package composition and historical size trends, helping developers inspect dependency impact before adoption. The project also provides package-size badges through Badgen and Shields.io. Its FAQ documents MissingDependencyError and BuildError cases and directs users to package metadata or issue reporting when analysis cannot be completed.
