webpack-license-plugin

A webpack plugin that extracts open source license information from npm packages in your webpack output. Current stable version is 4.5.1, released with regular updates. It supports webpack 2 through 5 and helps generate a bill of materials in JSON, HTML, CSV, or custom formats. Key differentiators include built-in license policy enforcement (fail on unacceptable licenses), exclusion of internal packages, and full test coverage. Since v4.4.1, the package ships both ESM and CJS builds with TypeScript types, and requires Node >=16.
