Authoring and previewing JSON-UI widgets as the response of running a project — the py-UDF-computes → json-widget-visualizes pattern, the {{ref}}/$param data grammar, how resolution runs through the compute backend, and the CLI surfaces (widget open, parley, deployed URL) that put a rendered widget
Authoring and previewing JSON-UI widgets as the response of running a project — the py-UDF-computes → json-widget-visualizes pattern, the {{ref}}/$param data grammar, how resolution runs through the compute backend, and the CLI surfaces (widget open, parley, deployed URL) that put a rendered widget in front of a human. Use whenever the desired output of a UDF/project is a widget, not raw data.
