source-map-loader

Webpack loader that extracts inline and linked source maps from JavaScript files, including from node_modules, so webpack can process them for the generated bundle. Current stable version is 5.0.0 (2024-01-15), with major releases roughly yearly. Key differentiator: it ensures source map continuity across third-party libraries, preventing misinterpretation by browsers. Requires webpack 5+ and Node.js 18.12+ as of v5. Supports a filterSourceMappingUrl option to control per-file behavior.
