babel-plugin-source-map-support
JSON →A Babel plugin (v2.2.0) that automatically prepends `import 'source-map-support/register'` to every transpiled file, enabling source-map-aware stack traces in v8 environments (Node.js, Chrome). It requires the separate `source-map-support` runtime dependency (v0.5+). Unlike manual registration or other plugins, it works with all Babel 7 presets and can be scoped to development builds via the `env` option. Stable, low maintenance, no known breaking changes since v1.
