Hi all,

I’ve integrated the example WebUIConfigModule into my Ignition Module but I’m struggling with data exchange.

How would I use my GatewayHook to query the data that is set in my WebUiConfig page?

Or indeed, how can I notify my GatewayHook when the user changes something in the WebUiConfig react app?

Thanks for any guidance.

8.1, or 8.3?

In 8.1 you set up a listener in your own code that will be notified by the platform whenever a configuration change is made:

In 8.3 the recommended pattern is to use a `SingletonResourceHandler` or `NamedResourceHandler` to react to changes in config so you don't have to set up all the listening infrastructure yourself:
