When building an app, you can set events for the components in order to listen to the changes of certain data. For example, for a Table component, the built-in events for the change of the selectedRow property include "Row select change", "Filter change", "Sort change", and "Page change".
However, there lacks similar events for some data changes, such as the changes of temporary states, transformers, or query results. Data responders are designed for these cases and allow you to listen and respond to any data change.
Events for data responders are more general than the events that listen to data changes such as content change, row select change, etc.
In query editor, click + New, and then select Data responder to create a new data responder.
You can set the data that data responder listens to. It supports all kinds of data formats, including number, string, array, and JS object. In the following example, any value change in the Text component triggers a global notification.
For detailed information, go to Event handlers > Actions.
