Function extensions

These tools provide additional, often simpler capabilities for data processing beyond functions:

• Modifier: Transform function output using JavaScript or JSONata.

• Filter: Interrupt or continue flows by generatetrue or false values.

• Error Handler: Catch potential errors thrown by a function.

• Memorizer: Directly work with UI data, such as user input, without injecting it as an input argument into a function.

• Recorder: Adds to the list, although it is actually a tool for recording and not processing data.

Extending functions

To extend a function:

1. Click the + icon behind the function output or behind an extension

2. Select the desired extension

Outputs can have parallel extensions to modify or filter values independently, and extensions can have extensions, too.

Deleting extensions

To delete an extension:

1. Right-click on an extension.

2. Select Delete.
