Interface: ExpressionBuilderProps

Defined in: packages/visual-editor/src/components/editors/expression-builder/ExpressionBuilder.tsx:31

Props provided to the expression editor render-prop slot.

packages/visual-editor is editor-agnostic — the host app provides the actual editor implementation (e.g. CodeMirror, Monaco) via a renderExpressionEditor prop on FunctionForm.
