function App() {
  type FormBuilderSchema = typeof FormBuilderSchema;
  type FormBuilderUiSchema = typeof FormBuilderUiSchema;
  type FormError = typeof FormError;

  const handleSchema = (schema: FormBuilderSchema) =>
    console.log("SCHEMA:", schema);
  const handleUiSchema = (uiSchema: FormBuilderUiSchema) =>
    console.log("UISchema:", uiSchema);
  const handleData = (data: unknown) => console.log("DATA:", data);

  const schema: FormBuilderSchema = {
    type: "object",
    properties: {
      firstName: {
        type: "string",
        minLength: 2,
        maxLength: 50,
