Very WIP! Not ready for release. Expect many bugs. Please don't sign builds on AMO with current ID.

* [chrome-native-messaging](https://github.com/jdiamond/chrome-native-messaging)

## Supported platforms

* Linux
* macOS (TODO)
* Windows (TODO)

Only tested on Linux. mDNS library issue to be fixed. `mdns` only works on Windows, `mdns-js` only works on Linux.


## Building

### Requirements

* NodeJS
* `node` binary in path
* ~~Bonjour SDK (Windows)~~

### Instructions

````sh
git clone https://github.com/hensm/caster.git
npm install
npm run build
````

Installer scripts aren't written yet, so registering the native messaging manifest with Firefox and specifiying the path must be done manually:  
[MDN: Native Manifests](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Native_manifests)

`path` key within `app/caster_bridge.json` must be set to absolute path of `app/src/launcher.sh` or `app/src/launcher.bat`. Then, the manifest must be either moved to the correct location or the path added to the registry (Windows):  
[MDN: Native Manifests # Manifest location](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Native_manifests#Manifest_location)

### Testing

Testing requires geckodriver (or chromedriver for Chrome parity testing). See [selenium-webdriver](https://www.npmjs.com/package/selenium-webdriver#installation) installation instructions (ignore `npm install`).

Chrome doesn't load the media router in a temporary selenium profile, so there's a bundled profile (`test/ChromeProfile.zip`). Extract the folder within as `test/ChromeProfile/`.

````sh
npm run build
npm test
SELENIUM_BROWSER=chrome npm test
````


## Usage

Extension can be loaded from `about:debugging` as a temporary extension.

Most sites won't load the cast API unless the browser presents itself as Chrome. The plan is to spoof the user agent string for a whitelist of cast-enabled sites, but that isn't implemented yet. You can workaround this by setting it manually or using a [third-party extension](https://addons.mozilla.org/en-US/firefox/search/?q=user+agent).

HTML5 media elements have a "Cast..." context menu item that triggers a sender application. Only works on remote (non-local) media that isn't DRM-encumbered.

Cast-enabled websites will load the sender API shim and display a cast button as in Chrome, provided there are no bugs/incompatibilities with the shim.
