Config Panel
When a user selects your node on the Automation Builder canvas, the config panel appears. You can build a custom React config panel using the SDK iframe sandbox, or rely on the auto-generated fallback UI derived from input_schema.
SDK iframe mechanism
The config panel uses the same iframe sandwich as widget editor panels:
Automation Builder (host) -> Supervisor iframe -> Extension Runtime iframe -> Your editor.tsx
Your extension must include "editor" in its targets array. The editor entry point renders your config panel component.
Using useLumioConfig
The useLumioConfig hook reads and writes the per-node-instance config (automation_nodes.config):
import { Lumio, CompactView } from "@zaflun/lumio-sdk";
import { useLumioConfig } from "@zaflun/lumio-sdk/hooks";
function ConfigPanel() {
const [config, setConfig] = useLumioConfig();
return (
<CompactView title="Threshold Settings">
<label>
Threshold:
<input
type="number"
value={config.threshold ?? 50}
onChange={(e) => setConfig({
...config,
threshold: Number(e.target.value),
})}
/>
</label>
<label>
Comparison:
<select
value={config.comparison ?? "greater_than"}
onChange={(e) => setConfig({
...config,
comparison: e.target.value,
})}
>
<option value="greater_than">Greater than</option>
<option value="less_than">Less than</option>
<option value="equal">Equal to</option>
</select>
</label>
</CompactView>
);
}
Lumio.render(<ConfigPanel />, { target: "editor" });
Changes sync back to automation_nodes.config via the parent host communication protocol.
Fallback UI
If your extension does not include an editor surface, the Automation Builder renders an auto-generated form based on node.input_schema. Each property in the schema becomes a form field:
| Schema type | UI element |
|---|---|
string | Text input |
number | Number input |
boolean | Checkbox |
string with enum | Select dropdown |
This fallback is sufficient for simple configurations. Use a custom editor surface when you need richer controls (color pickers, multi-step wizards, visual selectors).
