Connecting App to Website

[Bozark]

Hi, new to app inventor and very excited.

My goal is to host a webpage, where a user can write data to a cloud database. My app inventor app will then be notified that a data update has occurred, and take action on that data. It will then use bluetooth to command a robot based on that data, but that's out of scope for my question.

How can I / should I setup the cloud database and webpage? Should I use Cloud DB, Firebase, or TinyWebDB?

I followed the instructions on creating a custom TinyWebDB service, that accomplishes the cloud database and webpage functionality, but TinyWebDB does not have a .DataChanged method (or equivalent) which I desire.

Is it possible to add .DataChanged to TinyWebDB?
Is it possible to create webpages that can post to the storage offered by Cloud DB or Firebase for App Inventor (aka MIT's account)?

Any guidance is greatly appreciated!

You could probably run a php based tinyWebDB service, on your own server, then use a long polling process to return data to the app.

DataChanged for php tinywebDB

For those of you using or thinking of using a php based tinywebdb, I have, with some help and encouragement from @Juan_Antonio, come up with a data changed event solution. You see this event in use with CloudDB and FirebaseDB components, and believe what I have devised follows a similar approach of keeping a connection open to the data, watching for changes. In php terms is is called "long polling". The original concept comes from here: Try as I might, I could not get the caching to switch o…
