Description

Why

Establishes foundation for UI modernization per constitution v1.3.0. Implements layout-first refactoring as requested by @rezwana-karim to standardize all layout structures before component-level work, followed by comprehensive component refactoring and complete UI pages analysis. Current codebase lacked consistent component patterns, comprehensive design system documentation, clear mapping between API endpoints and UI surfaces, and a migration roadmap for existing pages.

What

Phase A (Layout-First Refactor) - COMPLETE ✅

All 4 core layouts refactored using shadcn/ui primitives and Tailwind design tokens:

Phase A.1 - Root & Dashboard Layouts (Commit 353b17a)

});

const form = useForm({

By submitting this pull request, I confirm that:

• I have read and agree to follow the Code of Conduct
• I have read the Contributing Guidelines
• My contribution is original work or properly attributed
• I agree to license my contribution under the project's MIT License

This pull request was created as a result of the following prompt from Copilot chat.

Objective:

• Read and enforce the StormCom constitution at .specify/memory/constitution.md (v1.3.0) and ensure all UI work follows its rules (TypeScript strict mode, Next.js v16 App Router, shadcn/ui usage, Tailwind CSS, accessibility, performance, and testing standards).
• Inspect the StormCom repository tech stack (package.json, tsconfig.json, tailwind.config.ts, next.config.js, app directory) to confirm actual versions and adapt the plan accordingly.
• Perform a comprehensive UI design audit and refactor of the StormCom frontend to adopt shadcn/ui primitives and templates. This includes redesigning layout, styles, and color palette into a consistent design system implemented via Tailwind tokens and shadcn/ui components.
• Analyze Next.js API route handlers (app/api/** and any route handlers) to derive UI requirements: list/detail pages, forms, dashboards, admin panels, toasts, error states, skeletons. Produce an API→UI mapping and implement or document missing UI surfaces.
• Implement the refactor progressively in CodeStorm-Hub/StormCom. Where new or modified components are needed upstream, create complementary PRs in CodeStorm-Hub/shadcn-ui and cross-reference them.

Scope:

• Refactor frontend code under src/app, src/components, src/styles/globals.css, tailwind.config.ts, theme provider, and any client UI code. Maintain behavior unless fixing bugs or accessibility/responsiveness issues.
• Maintain App Router Server Components-first architecture. Use 'use client' only where necessary.
• Use shadcn/ui CLI workflow (npx shadcn@latest init / add) and place components in src/components/ui/ per constitution.
• Use Tailwind CSS only (no CSS-in-JS). Implement theming with next-themes and CSS variables.

Detailed tasks:

1. Recon & verification
   • Clone repo, run npm install, confirm Node/NPM versions.
   • Run: npm run type-check, npx eslint ., npx vitest run (or available test commands), npm run dev to verify local dev server.
   • Document deviations from constitution versions and list required migrations.
2. Constitution review
   • Parse .specify/memory/constitution.md and extract UI rules and mandatory steps (shadcn init, next-themes, strict ts, testing and accessibility requirements).
3. API-driven UI mapping
   • Scan app/api/** route handlers, enumerate resources and actions.
   • For each endpoint, create a mapping doc (docs/ui-component-mapping.md) that lists required UI surfaces (list, detail, create/edit form, admin controls).
   • Mark endpoints missing UI and propose components/pages.
4. UI inventory & audit
   • Inventory current components in src/components and pages in src/app.
   • Identify duplicated components, inline styles, and accessibility issues. Run axe and report top issues.
   • Identify top 10 high-value refactors.
5. Design tokens & palette
   • Define Tailwind tokens in tailwind.config.ts (colors, spacing, radii, typography) with accessible color pairs. Implement dark mode using next-themes.
   • Add design tokens doc at src/styles/design-tokens.md.
6. Component migration & implementation
   • Initialize shadcn UI if not present: npx shadcn@latest init
   • Add and/or migrate components: Button, Input, Select, Checkbox, Radio, Dialog, Toast, Form primitives, Table/Card templates, Navigation, Header/Footer, Modal patterns.
   • Replace StormCom primitives progressively; create feature components in src/components/ composing shadcn primitives (e.g., ProductCard, CheckoutForm).
   • For missing variants, open focused PRs in CodeStorm-Hub/shadcn-ui or create local extensions under src/components/ui/ and mark for upstreaming.
7. Styles cleanup & performance
   • Remove unused CSS, avoid large imports, use next/dynamic where appropriate, and keep Server Components to minimize client JS.
   • Run bundle analysis and keep within constitution performance budgets.
8. Tests & E2E
   • Add/modify Vitest unit tests and Playwright E2E tests for critical flows: auth, product create/edit, checkout, order management.
   • Integrate axe checks and Percy snapshots for visual regression.
9. Documentation & migration notes
   • Update .github/instructions/*, CONTRIBUTING.md, and create docs/ui-component-mapping.md and migration guide.
10. PRs and delivery

• Create a feature branch: refactor/shadcn-ui-integration (or similar) and open a single comprehensive PR in CodeStorm-Hub/StormCom containing: summary, motivation, files changed, how to test, before/after screenshots, accessibility checklist, CI status, migration notes, and mapping docs.
• If shadcn-ui upstream changes are required, open focused PR(s) in CodeStorm-Hub/shadcn-ui and reference them.

Acceptance criteria:

• Repo builds, passes type checks and lint; test suite passes or failing tests are documented and fixed.
• Key API endpoints have corresponding, accessible UI surfaces implemented or documented with mockups/TODOs.
• Core UI primitives and templates use shadcn/ui components stored in src/components/ui/ or approved upstream variants.
• Tailwind tokens, dark-mode via next-themes, and design tokens implemented and documented.
• WCAG 2.1 Level AA violations resolved or documented with mitigation.
• Tests (unit, E2E) and Percy snapshots added/updated for critical pages.
• PR(s) created with clear migration guide and reviewers assigned.

Deliverables:

• Feature branch in CodeStorm-Hub/StormCom with commits implementing the refactor.
• PR on CodeStorm-Hub/StormCom with mapping docs, design tokens, tests, screenshots, and instructions.
• Focused PR(s) in CodeStorm-Hub/shadcn-ui if upstream changes are required.

Local commands & verification:

• npm install
• npm run type-check
• npx eslint . --fix
• npx vitest run
• npm run dev
• npx shadcn@latest init
• npx shadcn@latest add button input dialog toast

Notes & constraints:

• Preserve multi-tenant isolation: all DB queries must filter by storeId; do not change server-side API behavior.
• Non-breaking changes preferable; when breaking changes are required include a migration guide.
• Keep code and files within the project conventions (max file/function length, TS strictness).

Please implement the actionable refactor as described above, create the feature branch, and open the PR in CodeStorm-Hub/StormCom. Cross-reference any required shadcn-ui PRs in the StormCom PR.
