library1.0.1jsnpmunverified

Command-line interface for the Mozilla source-map library, enabling developers to resolve original source locations from minified or bundled JavaScript files. Current stable version is 1.0.1 (released March 2023) with irregular release cadence. Designed for debugging error stack traces in production, it supports resolving line/column mappings from source maps, showing context, and works with local files or URLs. Differentiator: provides an interactive CLI with visual context markers, unlike programmatic source-map libraries.
