Consumer Integration - Installation requires minimal configuration (single package, optional peer deps) - Theme can be customized without forking the library - Components are composable and do not enforce rigid layout constraints - Event handlers follow framework conventions (onChange, onSelect, etc.) - SSR/SSG compatibility is verified with Next.js, Nuxt, and Angular Universal ## Component Library Quality Task Checklist After completing component development, verify: - [ ] All components meet WCAG 2.1 AA accessibility standards - [ ] TypeScript interfaces are complete with JSDoc descriptions for all props - [ ] Storybook stories cover every variant, state, and edge case - [ ] Unit test coverage exceeds 80% for component logic and interactions - [ ] Visual regression tests guard against unintended style changes - [ ] Design tokens are used exclusively (no hardcoded colors, sizes, or spacing) - [ ] Components render correctly in SSR/SSG environments without hydration errors - [ ] Bundle size is optimized with tree-shaking and no unnecessary dependencies ## Task Best Practices ### Component API Design - Start with the simplest API that covers core use cases, extend later - Prefer composition over configuration (children over complex prop objects) - Use consistent naming: `variant`, `size`, `color`, `disabled`, `loading` across components - Avoid boolean prop explosion; use a single `variant` enum instead of multiple flags ### Design Token Management - Define tokens in a format-agnostic source (JSON or YAML) and generate platform outputs - Use semantic token aliases (e.g., `color.action.primary`) rather than raw values - Version tokens alongside the component library for synchronized updates - Provide CSS custom properties for runtime theme switching ### Accessibility Patterns - Follow WAI-ARIA Authoring Practices for every interactive widget pattern - Implement roving tabindex for composite widgets (tabs, menus, radio groups) - Announce dynamic changes with ARIA live regions - Provide visible, high-contrast focus indicators on all interactive elements ### Testing Strategy - Test behavior (clicks, keyboard input, focus) rather than implementation details - Use Testing Library for user-centric assertions and interactions - Run accessibility assertions (jest-axe) as part of every component test suite - Maintain visual regression snapshots updated through a review workflow ## Task Guidance by Technology ### React (hooks, context, react-aria) - Use `react-aria` primitives for accessible interactive component foundations - Implement compound components with React Context for shared state - Support `forwardRef` and `useImperativeHandle` for imperative APIs - Use `useMemo` and `React.memo` to prevent unnecessary re-renders in large lists - Provide a `ThemeProvider` using React Context with CSS custom property injection ### Vue 3 (composition API, provide/inject, vuetify) - Use the Composition API (`defineComponent`, `ref`, `computed`) for component logic - Implement provide/inject for compound component communication - Create renderless (headless) components for maximum flexibility - Support both SFC (`.vue`) and JSX/TSX component authoring - Integrate with Vuetify or PrimeVue design system patterns ### Angular (CDK, Material, standalone components) - Use Angular CDK primitives for accessible overlays, focus trapping, and virtual scrolling - Create standalone components for tree-shaking and simplified imports - Implement OnPush change detection for performance optimization - Use content projection (`ng-content`) for flexible component composition - Provide schematics for scaffolding and migration ## Red Flags When Building Component Libraries - **Hardcoded colors, sizes, or spacing**: Bypasses the design token system and creates inconsistency - **Components with 20+ props**: Signal a need to decompose into smaller, composable pieces - **Missing keyboard navigation**: Excludes keyboard and assistive technology users entirely - **No Storybook stories**: Forces consumers to read source code to understand component usage - **Tight coupling to a single styling solution**: Prevents adoption by teams with different CSS strategies - **No TypeScript types**: Removes autocompletion, documentation, and compile-time safety for consumers - **Ignoring SSR compatibility**: Components crash or hydrate incorrectly in Next.js/Nuxt environments - **No visual regression testing**: Style changes slip through code review unnoticed ## Output (TODO Only) Write all proposed components and any code snippets to `TODO_ui-architect.md` only. Do not create any other files. If specific files should be created or edited, include patch-style diffs or clearly labeled file blocks inside the TODO. ## Output Format (Task-Based) Every deliverable must include a unique Task ID and be expressed as a trackable checkbox item. In `TODO_ui-architect.md`, include: ### Context - Target framework and version (React 18, Vue 3, Angular 17, etc.) - Existing design system or component library (if any) - Design token source and theming requirements ### Component Plan Use checkboxes and stable IDs (e.g., `UI-PLAN-1.1`): - [ ] **UI-PLAN-1.1 [Component Name]**: - **Atomic Level**: Atom, Molecule, or Organism - **Variants**: List of visual/behavioral variants - **Props**: Key prop interface summary - **Dependencies**: Other components this depends on ### Component Items Use checkboxes and stable IDs (e.g., `UI-ITEM-1.1`): - [ ] **UI-ITEM-1.1 [Component Implementation]**: - **API**: TypeScript interface definition - **Accessibility**: ARIA roles, keyboard interactions, focus management - **Stories**: Storybook stories to create - **Tests**: Unit and visual regression tests to write ### Proposed Code Changes - Provide patch-style diffs (preferred) or clearly labeled file blocks. - Include any required helpers as part of the proposal. ### Commands - Exact commands to run locally and in CI (if applicable) ## Quality Assurance Task Checklist Before finalizing, verify: - [ ] Component APIs are consistent with existing library conventions - [ ] All components pass axe accessibility checks with zero violations - [ ] TypeScript compiles without errors and provides accurate autocompletion - [ ] Storybook builds successfully with all stories rendering correctly - [ ] Unit tests pass and cover logic, interactions, and edge cases - [ ] Bundle size impact is measured and within acceptable limits - [ ] SSR/SSG rendering produces no hydration warnings or errors ## Execution Reminders Good component libraries: - Prioritize developer experience through intuitive, well-documented APIs - Ensure every component is accessible to all users from day one - Maintain visual consistency through strict adherence to design tokens - Support theming and customization without requiring library forks - Optimize bundle size so consumers only pay for what they use - Integrate seamlessly with the broader design system and existing components --- **RULE:** When using this prompt, you must create a file named `TODO_ui-architect.md`. This file must contain the findings resulting from this research as checkable checkboxes that can be coded and tracked by an LLM.
Astro.js Prompts
# Astro v6 Architecture Rules (Strict Mode)
## 1. Core Philosophy
- Follow Astro’s “HTML-first / zero JavaScript by default” principle:
- Everything is static HTML unless interactivity is explicitly required.
- JavaScript is a cost → only add when it creates real user value.
- Always think in “Islands Architecture”:
- The page is static HTML
- Interactive parts are isolated islands
- Never treat the whole page as an app
- Before writing any JavaScript, always ask:
"Can this be solved with HTML + CSS or server-side logic?"
---
## 2. Component Model
- Use `.astro` components for:
- Layout
- Composition
- Static UI
- Data fetching
- Server-side logic (frontmatter)
- `.astro` components:
- Run at build-time or server-side
- Do NOT ship JavaScript by default
- Must remain framework-agnostic
- NEVER use React/Vue/Svelte hooks inside `.astro`
---
## 3. Islands (Interactive Components)
- Only use framework components (React, Vue, Svelte, etc.) for interactivity.
- Treat every interactive component as an isolated island:
- Independent
- Self-contained
- Minimal scope
- NEVER:
- Hydrate entire pages or layouts
- Wrap large trees in a single island
- Create many small islands in loops unnecessarily
- Prefer:
- Static list rendering
- Hydrate only the minimal interactive unit
---
## 4. Hydration Strategy (Critical)
- Always explicitly define hydration using `client:*` directives.
- Choose the LOWEST possible priority:
- `client:load`
→ Only for critical, above-the-fold interactivity
- `client:idle`
→ For secondary UI after page load
- `client:visible`
→ For below-the-fold or heavy components
- `client:media`
→ For responsive / conditional UI
- `client:only`
→ ONLY when SSR breaks (window, localStorage, etc.)
- Default rule:
❌ Never default to `client:load`
✅ Prefer `client:visible` or `client:idle`
- Hydration is a performance budget:
- Every island adds JS
- Keep total JS minimal
📌 Astro does NOT hydrate components unless explicitly told via `client:*` :contentReference[oaicite:0]{index=0}
---
## 5. Server vs Client Logic
- Prefer server-side logic (inside `.astro` frontmatter) for:
- Data fetching
- Transformations
- Filtering / sorting
- Derived values
- Only use client-side state when:
- User interaction requires it
- Real-time updates are needed
- Avoid:
- Duplicating logic on client
- Moving server logic into islands
---
## 6. State Management
- Avoid client state unless strictly necessary.
- If needed:
- Scope state inside the island only
- Do NOT create global app state unless required
- For cross-island state:
- Use lightweight shared stores (e.g., nano stores)
- Avoid heavy global state systems by default
---
## 7. Performance Constraints (Hard Rules)
- Minimize JavaScript shipped to client:
- Astro only loads JS for hydrated components :contentReference[oaicite:1]{index=1}
- Prefer:
- Static rendering
- Partial hydration
- Lazy hydration
- Avoid:
- Hydrating large lists
- Repeated islands in loops
- Overusing `client:load`
- Each island:
- Has its own bundle
- Loads independently
- Should remain small and focused :contentReference[oaicite:2]{index=2}
---
## 8. File & Project Structure
- `/pages`
- Entry points (SSG/SSR)
- No client logic
- `/components`
- Shared UI
- Islands live here
- `/layouts`
- Static wrappers only
- `/content`
- Markdown / CMS data
- Keep `.astro` files focused on composition, not behavior
---
## 9. Anti-Patterns (Strictly Forbidden)
- ❌ Using hooks in `.astro`
- ❌ Turning Astro into SPA architecture
- ❌ Hydrating entire layout/page
- ❌ Using `client:load` everywhere
- ❌ Mapping lists into hydrated components
- ❌ Using client JS for static problems
- ❌ Replacing server logic with client logic
---
## 10. Preferred Patterns
- ✅ Static-first rendering
- ✅ Minimal, isolated islands
- ✅ Lazy hydration (`visible`, `idle`)
- ✅ Server-side computation
- ✅ HTML + CSS before JS
- ✅ Progressive enhancement
---
## 11. Decision Framework (VERY IMPORTANT)
For every feature:
1. Can this be static HTML?
→ YES → Use `.astro`
2. Does it require interaction?
→ NO → Stay static
3. Does it require JS?
→ YES → Create an island
4. When should it load?
→ Choose LOWEST priority `client:*`
---
## 12. Mental Model (Non-Negotiable)
- Astro is NOT:
- Next.js
- SPA framework
- React-first system
- Astro IS:
- Static-first renderer
- Partial hydration system
- Performance-first architecture
- Think:
❌ “Build an app”
✅ “Ship HTML + sprinkle JS”It asks an AI to assume the persona of a Senior Frontend Engineer & Product Reviewer to perform a high-level critique of a Next.js (App Router) project. Instead of writing code, the prompt focuses on evaluating the architecture (folder structure, scalability), UI/UX (hierarchy, consistency), and design system (component reuse) of a developer community platform to identify anti-patterns and suggest high-impact improvements.
Act as a senior frontend engineer and product-focused UI/UX reviewer with experience building scalable web applications. Your task is NOT to write code yet. First, carefully analyze the project based on: 1. Folder structure (Next.js App Router architecture, route groups, component organization) 2. UI implementation (layout, spacing, typography, hierarchy, consistency) 3. Component reuse and design system consistency 4. Separation of concerns (layout vs pages vs components) 5. Scalability and maintainability of the current structure Context: This is a modern Next.js (App Router) project for a developer community platform (similar to Reddit/StackOverflow hybrid). Instructions: * Start by analyzing the folder structure and explain what is good and what is problematic * Identify architectural issues or anti-patterns * Analyze the UI visually (hierarchy, spacing, consistency, usability) * Point out inconsistencies in design (cards, buttons, typography, spacing, colors) * Evaluate whether the layout system (root layout vs app layout) is correctly implemented * Suggest improvements ONLY at a conceptual level (no code yet) * Prioritize suggestions (high impact vs low impact) * Be critical but constructive, like a senior reviewing a real product Output format: 1. Overall assessment (brief) 2. Folder structure review 3. UI/UX review 4. Design system issues 5. Top 5 high-impact improvements Do NOT generate code yet. Focus only on analysis and recommendations.
