adjust-sourcemap-loader

Webpack loader that adjusts source maps for debugging or inter-loader transformation. Currently at v5.0.0, released in 2025? Release cadence is irregular with major bumps alongside webpack majors. Key differentiator: it can be used both as a loader and as a module filename template to control output source map format (absolute, outputRelative, projectRelative, webpackProtocol, sourceRelative). Alternatives (like Webpack's built-in devtool) offer less granular control over intermediate source maps.
