shadcn Component Visual Adapter

# shadcn Component Visual Adapter ## Objective Refactor the existing `${component_name}` component located at `${component_file_path}` to match the visual design, structure, and behavior of the reference component available at: > ${install_command:bunx --bun shadcn@latest add accordion} ${reference_url:} ← optional; leave blank if no docs page exists Do NOT replace business logic, existing props interface, or data-fetching patterns. Preserve them. Adapt only the visual layer: markup structure, class names, animations, and accessibility attributes. ## Step 1 - Analyze the Existing Component Before writing any code: 1. Read the full source of `${component_file_path}`. 2. Map out: - All props and their types (TypeScript interfaces or PropTypes). - Internal state variables (`useState`, `useReducer`, Zustand slices, etc.). - Context providers or custom hooks consumed. - Child components rendered and where they live. - Event handlers and callbacks exposed to the parent. 3. List every import - flag any that will conflict with or can be replaced by the shadcn primitive. Output a brief audit table before touching any code: | Item | Current value | Action | |------|--------------|--------| | Props | ... | keep / rename / remove | | State | ... | keep / migrate | | Context/Hooks | ... | keep / replace | | Sub-components | ... | keep / replace | | Dependencies | ... | keep / install / remove | ## Step 2 - Dependency Resolution Run the install command directly: ${install_command} After the command completes, the generated files will appear in ${components_dir:components/ui}/. Proceed to Step 3 using those files. ## Step 3 - Review Reference Component IF ${reference_url} is provided → fetch it and extract the visual spec as before. IF ${reference_url} is blank → read the files downloaded by the CLI command in Step 2 and extract the same information from the source code directly: - cva variant schema - data-state / data-disabled attributes - animation/transition classes - ARIA roles and props - cn() usage patterns ## Step 4 - Refactor the Component Apply the visual structure from Step 3 to the existing component from Step 1. ### Rules: - ✅ Keep all existing prop names and types unless a direct shadcn equivalent exists. - ✅ Keep all data-fetching, business logic, and callbacks. - ✅ Wrap Radix primitives using `forwardRef` and spread `...props` to preserve flexibility. - ✅ Use `cn()` for all className merging - never string concatenation. - ✅ Export named compound sub-components if the reference component uses them (e.g., `Accordion`, `AccordionItem`, `AccordionTrigger`, `AccordionContent`). - ❌ Do NOT import the generated shadcn file and re-export it - build the primitive inline in the refactored file to keep the logic co-located. - ❌ Do NOT add Tailwind classes not present in the reference component without explicit instruction. ### Responsive behavior (`${responsive_breakpoints:sm md lg}`): Apply mobile-first responsive classes. Confirm current breakpoints in `tailwind.config.ts` match the project's convention. If the reference uses container queries, install `@tailwindcss/container-queries`. ## Step 5 - Context Providers and Hooks If the reference component requires a context provider (e.g., `ToastProvider`, `TooltipProvider`): 1. Check if it is already mounted in `${provider_file:app/layout.tsx}` or `${provider_file:app/providers.tsx}`. 2. If not, add it to the appropriate layout file. Provide the exact diff. 3. If a custom hook is required (e.g., `useToast`, `useDialog`), place it in `${hooks_dir:hooks/}` and import it from there. ## Step 6 - Clarifying Questions (ask before generating if unknown) If any of the following are not determinable from the existing code, ask before writing: 1. **Data/props**: What shape of data will be passed? (Provide a sample object if helpful.) 2. **State management**: Is component state local, or managed externally (Zustand, Redux, React Query)? 3. **Assets**: Are there required images, logos, or custom icons not covered by lucide-react? 4. **Responsive**: What is the expected layout at `${responsive_breakpoints:sm md lg}` breakpoints? 5. **Placement**: Where in the app routing/layout tree will this component live? (Important for context provider placement.) ## Step 7 - Output Format Provide the result as: 1. **`${component_file_path}`** - full refactored component file. 2. **`${components_dir:components/ui}/${shadcn_component_slug}.tsx`** - shadcn primitive (only if needed and not generated by CLI). 3. **`lib/utils.ts`** - only if it needs to be created or updated. 4. **Layout/provider diff** - only if a provider needs to be added. 5. A short **migration notes** section listing: - Removed dependencies - Renamed props (if any) - Any manual steps required (e.g., adding CSS variables to `globals.css`) ## Tailwind CSS Variables (shadcn design tokens) Confirm that `globals.css` contains the required CSS custom properties. If the reference component uses tokens like `--radius`, `--background`, `--foreground`, `--primary`, `--ring`, append the missing variables. Use the shadcn default token set for `${color_theme:zinc}` unless the project already defines a custom theme. ## Constraints - Framework: **${framework:Next.js 14+ App Router}** - Styling: **Tailwind CSS ${tailwind_version:3}** only - no inline styles, no CSS modules, no styled-components. - TypeScript: **strict mode**. All new code must be fully typed. - Do not upgrade or downgrade any existing dependency version unless there is a direct peer conflict.
