# WebRTC adapter #

adapter.js is a shim to insulate apps from spec changes and prefix differences in WebRTC. The prefix differences are mostly gone these days but differences in behaviour between browsers remain.



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

```bash

npm install webrtc-adapter

```



#### Bower

```bash

bower install webrtc-adapter

```



## Usage ##

##### Javascript

Just import adapter:

```

import adapter from 'webrtc-adapter';

```

No further action is required. You might want to use adapters browser detection

which detects which webrtc quirks are required. You can look at

```

adapter.browserDetails.browser

```

for webrtc engine detection (which will for example detect Opera or the Chromium based Edge as 'chrome') and

```

adapter.browserDetails.version

```

for the version according to the user-agent string.



##### 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](https://github.com/webrtc/samples) as an example on how you can do this.



#### Prebuilt releases

##### Web

In the [gh-pages branch](https://github.com/webrtcHacks/adapter/tree/gh-pages) 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_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](https://github.com/webrtcHacks/adapter/blob/master/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 ``. Run `npm 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](https://github.com/webrtcHacks/adapter/releases/tag/v3.4.1).

* Go back to your checkout and run `git pull`

* Run `npm publish` (you need access to the [webrtc-adapter npmjs package](https://www.npmjs.com/package/webrtc-adapter)). For big changes, consider using a [tag version](https://docs.npmjs.com/adding-dist-tags-to-packages) such as `next` and then [change the dist-tag after testing](https://docs.npmjs.com/cli/dist-tag).

* 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.
