source-map-support

Provides source map support for stack traces in Node.js and browsers via the V8 stack trace API. Current stable version: 0.5.21. Uses the Mozilla source-map module to replace paths and line numbers of source-mapped files with originals. Key differentiator: works with any compile-to-JS language, supports both CLI (-r) and programmatic usage, and includes browser support via bundled script. Maintained by Evan Wallace, releases are infrequent but stable.
