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.

This repository used to be part of the WebRTC organisation on github but moved. We aim to keep the old repository updated with new releases.

Install

NPM

npm install webrtc-adapter

Bower

bower install webrtc-adapter

Usage

Javascript

Just import adapter:

import adapter from 'webrtc-adapter';

No further action is required.

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 https://webrtc.github.io/adapter/adapter-latest.js. Specific versions can be found at https://webrtc.github.io/adapter/adapter-N.N.N.js, e.g. https://webrtc.github.io/adapter/adapter-1.0.2.js.

Bower

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

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

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

Publish a new version

• Go to the adapter repository root directory
• Make sure your repository is clean, i.e. no untracked files etc. Also check that you are on the master branch and have pulled the latest changes.
• 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
• Go to the releases tab in the GitHub web ui and edit the tag.
• Add a summary of the recent commits in the tag summary and a link to the diff between the previous and current version in the description, example.
• Go back to your checkout and run git pull
• Run npm publish (you need access to the webrtc-adapter npmjs package). For big changes, consider using a tag version such as next and then change the dist-tag after testing.
• 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.

Publish a hotfix patch versions

In some cases it may be necessary to do a patch version while there are significant changes changes on the master branch. To make a patch release,

• checkout the latest git tag using git checkout tags/vMajor.minor.patch.
• checkout a new branch, using a name such as patchrelease-major-minor-patch.
• cherry-pick the fixes using git cherry-pick some-commit-hash.
• run npm version patch. This will create a new patch version and publish it on github.
• check out origin/bumpVersion branch and publish the new version using npm publish.
• the branch can now safely be deleted. It is not necessary to merge it into the main branch since it only contains cherry-picked commits.
