adapter.js is a shim that insulates WebRTC applications from specification changes and browser prefix differences.
The tool solves the problem of WebRTC implementations diverging across browsers. While prefix differences have largely disappeared, behavioral differences between browsers remain. adapter.js provides a compatibility layer that normalizes these differences, allowing developers to write WebRTC code once without worrying about browser-specific quirks. The shim works by detecting which WebRTC quirks are present in the user's browser and applying appropriate fixes transparently.
Developers building WebRTC applications should use this tool if they need to support multiple browsers with inconsistent WebRTC implementations. It suits any project using WebRTC APIs where cross-browser compatibility matters. The tool offers flexibility in how it's consumed: a global adapter object is available when using the standard build, while a no-global variant allows integration into module systems without polluting the global namespace. Installation is straightforward through NPM or Bower, with prebuilt releases also available for direct linking.
The project maintains a formal release process with semantic versioning and publishes to both NPM and a GitHub pages distribution channel. Development is coordinated through pull requests with testing requirements before merging. The repository was transferred from the WebRTC organization but the maintainers keep the original repository synchronized with new releases.
