How to interact with JavaScript? about cordova-plugin-today-widget HOT 4 CLOSED

From the official Apple docs:

Opening the Containing App

In some cases, it can make sense for a Today widget to request its containing app to open. For example, the Calendar widget in OS X opens Calendar when users click an event. (Note that in iOS, a user may have to unlock the device before the containing app can open.) To ensure that your containing app opens in a way that makes sense in the context of the user’s current task, you need to define a custom URL scheme that both the app and its widgets can use.

A widget doesn’t directly tell its containing app to open; instead, it uses the openURL:completionHandler: method of NSExtensionContext to tell the system to open its containing app. When a widget uses this method to open a URL, the system validates the request before fulfilling it.

So you will probably need cordova-plugin-customurlscheme to create your own url-scheme, add it to your iOS app and then open your app via openUrl in your widget, then you will be able to send a parameter which tells your app that it was opened by your widget.

Thanks @DavidStrausz ! That's really helpful! ❤️

Another question is, how to update the widget based on information from JavaScript? For example, a TODO list widget should get the list from the App. Would that be too much to ask? 🤦‍♂

No problem, glad to help! :)

Usually you use shared user defaults to exchange (simple) data (your app and your widget are in the same app-group and can therefore access the same user defaults).
Check this article.

You will probably want to use cordova-plugin-nativestorage to save e.g. the TODO list. Especially this section will be of interest for your use-case.

If you need a more advanced data-exchange you could also think about sharing an API-key in the user defaults, so your widget and your app can access the same backend.
