Installation & setup

npm install @coderevivehq/source-map-url

The npm package supports Node.js 18 and later. The distributed UMD module can also be loaded with AMD or as the browser global sourceMappingURL.

Documentation

Detailed documentation is maintained in the docs/ directory. Start with the documentation overview, then use the Usage guide, API reference, Examples, Migration guide, and Troubleshooting guide.

Usage

var sourceMappingURL = require("@coderevivehq/source-map-url")

var code = "console.log('hello')\n//# sourceMappingURL=app.js.map"

sourceMappingURL.getFrom(code)
// "app.js.map"

code = sourceMappingURL.removeFrom(code)

The package also provides existsIn and insertBefore. See the API reference for their contracts and edge cases.

Migration

Replace the original package name in the dependency and import. The four helper methods keep their established signatures. See the Migration guide for the exact change and the corrected handling of comment-like text inside strings.

Contributing

Bug reports, focused improvements, and documentation updates are welcome through GitHub issues and pull requests. Please run npm test before submitting a change.
