WebRTC adapter

[adapter.js] is a shim to insulate apps from spec changes and prefix differences. In fact, the standards and protocols used for WebRTC implementations are highly stable, and there are only a few prefixed names. For full interop information, see webrtc.org/web-apis/interop.

Install

Bower

bower install webrtc-adapter#gh-pages

One caveat is that the version is gh-pages hence you will get the latest adapter.js unless you manually specify a version. See Usage instructions for more details.

NPM

npm install webrtc-adapter

Usage

NPM

Copy to desired location in your src tree or use a minify/vulcanize tool (node_modules is usually not published with the code). See webrtc/samples repo as an example on how you can do this.

Prebuilt releases

Web

In the gh-pages branch prebuilt ready to use files can be downloaded/linked directly. Latest version can be found at http://webrtc.github.io/adapter/adapter-latest.js. Specific versions can be found at http://webrtc.github.io/adapter/adapter-N.N.N.js, e.g. http://webrtc.github.io/adapter/adapter-1.0.2.js.

Bower

You will find adapter.js in bower_components/webrtc-adapter/.

Due to using the gh-pages branch as a version, you cannot use the bower package version for making sure you are using the correct version, rather you have to statically link the adapter-version file yourself, e.g. if you want version 1.0.5 you have to use the following file: bower_components/webrtc-adapter/adapter-1.0.5.js.

NPM

In node_modules/webrtc-adapter/out/ folder you will find 4 files:

• adapter.js - includes all the shims and is visible in the browser under the global adapter object (window.adapter).
• adapter_no_edge.js - same as above but does not include the Microsoft Edge (ORTC) shim.
• adapter_no_edge_no_global.js - same as above but is not exposed/visible in the browser (you cannot call/interact with the shims in the browser).
• adapter_no_global.js - same as adapter.js but is not exposed/visible in the browser (you cannot call/interact with the shims in the browser).

Include the file that suits your need in your project.

Development

Detailed information on developing in the webrtc github repo can be found in the WebRTC GitHub repo developer's guide.

Head over to test/README.md and get started developing.

Publish a new version

• Go the the adapter repository root directory
• Make sure your repository is clean, i.e. no untracked files etc
• Depending on the impact of the release, either use patch, minor or major in place of <version>. Run npm version <version> -m 'bump to %s' and type in your password lots of times (setting up credential caching is probably a good idea).
• Create and merge the PR if green in the GitHub web ui
• Run git pull
• Run npm publish
• Done! There should now be a new release published to NPM and the gh-pages branch.

Note: Currently only tested on Linux, not sure about Mac but will definitely not work on Windows.
