Browser-component

Browser component is a web component designed to get a browser into the browser itself. It can be used to extend a headless browser, or give some more features to a web application, such as firefox/xulrunner or chrome/chromium apps. This project comes with sub components, to let you customize the browser of your wish.

Overview

Get it directly by cloning this repository:

git clone https://github.com/jokesterfr/browser-component.git

Or use bower:

bower install browser-component

Import it in your page like so:

<link rel="import" href="./bower_components/browser-component/dist/browser-component.html" />

And use it:

<browser-component defaultPage="https://github.com">

Testing example

If you want to test this component in a chrome app context, simply type:

npm run example

Browser compatibility

As of today, web components are not natively supported by Firefox, Chrome and chromium support web components since version 35.

Check browser compatibility.

This browser-component uses the chrome webview tag. A tweak could be made to use the equivalent XUL browser tag, to be supported by Firefox. Therefore, the lack of Web components support does not urge me to do so.

Components API
