## What it is
adapter.js is a JavaScript shim that insulates WebRTC applications from spec changes and browser prefix/behavior differences. It normalizes the WebRTC API across browsers and exposes browser detection details.

## Use cases
- make WebRTC apps work consistently across Chrome, Firefox, and Safari
- handle browser prefix differences in getUserMedia and RTCPeerConnection
- detect which browser and WebRTC quirks the user needs
- polyfill older browsers with nonstandard WebRTC APIs
- build video chat apps without writing per-browser code

## When to choose
- you are building a WebRTC-based app that must support multiple browsers
- you want a maintained shim instead of hand-rolled browser detection
- you need consistent behavior for getUserMedia, RTCPeerConnection, and related APIs

## When to avoid
- you only target a single modern browser with no legacy quirks
- your app does not use WebRTC at all
- you need a full WebRTC implementation rather than an API shim

## Facets
- artifact type: library
- maturity: maintenance
- function: middleware, developer-tools
- domain: web-development, browser-extensions, cross-platform
- platform: browser
- tags: webrtc, polyfill, shim, browser-compatibility, real-time-communication, nodejs, javascript
