/** * Give warnings based on component composition (which slot/parent a child is rendered in). * * Used when child components need to know which slot/parent they are rendered in * (e.g. `FormSummary.Header` vs `FormSummary.Footer`) and should warn or error in development * if placed in a discouraged or forbidden slot. * * Usage: * - Wrap slot components with <CompositionWarning.Root name="FormSummary.Header">...</CompositionWarning.Root> * - In child: `<CompositionWarning.Forbidden name="FormSummary.Header" />` to forbid slot. * * This is guidance only: warnings are logged to the console in development, never enforced at runtime. */ import React, { useEffect, useRef } from "react"; import { Slot } from "../../slot/Slot.js"; import { createContext } from "../create-context.js"; const isDev = process.env.NODE_ENV !== "production"; const [CompositionWarning, useCompositionWarning] = createContext({ errorMessage: "useCompositionWarning() must be used within <CompositionWarning />", }); function CompositionWarningForbidden({ children, name, message, }) { var _a; const compositionName = (_a = useCompositionWarning(false)) === null || _a === void 0 ? void 0 : _a.name; const elementRef = useRef(null); useEffect(() => { if (!isDev || !compositionName || name !== compositionName) { return; } console.warn(`[Aksel] ${message}\nElement: `, elementRef.current); }, [compositionName, name, message]); return React.createElement(Slot, { ref: elementRef }, children); } export { CompositionWarningForbidden as Forbidden, CompositionWarning as Root }; //# sourceMappingURL=CompositionWarning.js.map
