I did this because I was tired of having to `⌘-tab` or `alt-tab` to my browser and then search through the numerous open tabs when I was using [Facebook Messenger](http://messenger.com) or [Whatsapp Web](http://web.whatsapp.com).
On OSX, the icon parameter should be a path to an `.icns` file. [iConvertIcons](https://iconverticons.com/online/) can be used to convert `.pngs`, though it can be quite cumbersome.
To retrieve the `.icns` file from the downloaded file, extract it first and press File > Get Info. Then select the icon in the top left corner of the info window and press `⌘-C`. Open Preview and press File > New from clipboard and save the `.icns` file. It took me a while to figure out how to do that and question why a `.icns` file was not simply provided in the downloaded archive.
On OSX, it is desired for the App dock icon to show a badge on the receipt of a desktop notification.
There is no known way to intercept and set an event listener for a desktop notification triggered by the [`<webview>`](https://github.com/atom/electron/blob/master/docs/api/web-view-tag.md), the current workaround is to listen for `document.title` changes within the `<webview>`. Typical web apps like Facebook Messenger will change the `document.title` to "John sent a message..." on the receipt of a desktop notification, and this is what we will listen for to trigger the app badge on the dock.
However, this would cause issues when the command line argument `target` is set to a external page which is not a single page app, because clicking on hyperlinks and switching pages would naturally change the `document.title`. Hence, `--badge` is an optional command argument that can be set by the user if the side effect of this workaround is understood.
A template app with the appropriate event listeners and callbacks set up is included in the `/app` folder. When the `nativefier` command is executed, this folder is copied to a temporary directory with the appropriate parameters in a configuration file, and the core methods of `electron-packager` is called on that directory.
## Notes
Tested only on OSX, but should work for windows and linux.
### Back Button
A back button is intentionally not provided because the tool is designed for single page apps. However, if desired, an executable can built for any url, and simply pressing the `backspace` key will take the user back to the previous page.
