Add WebRTC browser compatibility to your web app by importing adapter.js so your video call code works across Chrome, Firefox, and Safari without changes.
Use the browser detection utility in adapter.js to identify which browser version a user is running and handle remaining browser-specific quirks in your own code.

Figures from each repo's GitHub metadata at analysis time.
WebRTC adapter (also called adapter.js) is a small JavaScript library that smooths over differences in how web browsers implement real-time communication features. WebRTC is the browser technology that powers video calls, voice calls, and peer-to-peer data transfer directly in the browser without any plugins. Different browsers have historically implemented parts of this standard in slightly different ways, which causes code that works in one browser to break in another. Adapter.js sits between your application code and the browser, quietly fixing those inconsistencies so you can write your WebRTC code once and have it work across browsers. The README notes that the bigger prefix differences that existed years ago are mostly resolved, but behavioral differences between browsers still remain, which is why the library continues to be maintained. The library also exposes a small browser detection utility that identifies which browser and version is running, which can be useful for handling any remaining browser-specific quirks in your own code. Installing it is straightforward: add it through npm or Bower, then import it at the top of your JavaScript file. No further configuration is needed beyond that import. Pre-built files are also available for direct download or linking if you prefer not to use a package manager. The library is a JavaScript shim, meaning it modifies browser APIs in place at runtime to bring them into alignment with the current specification. It is available on npm as the webrtc-adapter package and is widely used by developers building video and audio communication features into web applications.
