App Migration to Shared Packages

All web apps now use the shared packages consistently:

Logo Components - Migrated to @mana/shared-branding:

• memoro/apps/web/src/lib/components/MemoroLogo.svelte → uses AppLogo
• cards/apps/web/src/lib/components/CardsLogo.svelte → uses AppLogo
• mana/apps/web/src/lib/components/ManaLogo.svelte → uses AppLogo
• maerchenzauber/apps/web/src/lib/components/StorytellerLogo.svelte → uses AppLogo

Formatter Functions - Migrated to @mana/shared-utils:

• memoro/apps/web/src/lib/components/memo/AdditionalRecordings.svelte → uses formatDurationFromMs, formatFileSize
• memoro/apps/web/src/lib/components/RecordingButton.svelte → uses formatDuration
• memoro/apps/web/src/lib/components/statistics/OverviewCard.svelte → uses formatDurationWithUnits
• memoro/apps/web/src/lib/components/statistics/InsightsCard.svelte → uses formatDurationWithUnits
• memoro/apps/web/src/lib/components/statistics/ProductivityCard.svelte → uses formatDurationWithUnits

---

Planned Shared Packages

1. Shared UI Components (@mana/shared-ui)

Status: Done Priority: High Estimated LOC Savings: 500-800 per app

Components to unify:

• Button.svelte - Primary, secondary, ghost, danger variants
• Input.svelte - Text input with label, error states
• Text.svelte - Typography component with variants
• Modal.svelte - Overlay modal with header, body, footer slots
• Spinner.svelte - Loading indicator
• Toast.svelte - Notification toasts
• Badge.svelte - Status badges
• Card.svelte - Content container
• Dropdown.svelte - Select/dropdown menus

Apps using these:

• Mana Web
• Memoro Web
• Maerchenzauber Web
• Cards Web

---

2. Shared Auth (@mana/shared-auth)

Status: Done Priority: High Estimated LOC Savings: 800-1200 per app

Modules to unify:

• tokenManager.ts - JWT token storage, refresh, validation
• authService.ts - Login, logout, register, password reset
• supabaseClient.ts - Authenticated Supabase client factory
• authStore.ts - Svelte store for auth state
• authGuard.ts - Route protection utilities

Considerations:

• Each app may have different Supabase projects
• Token storage strategy (localStorage vs cookies)
• OAuth providers per app

---

3. Shared Tailwind Config (@mana/shared-tailwind)

Status: Done Priority: High Estimated Benefit: Consistent branding, easier theme updates

Config unified:

• Color palette (primary, secondary, accent colors)
• Theme variants (Lume, Nature, Stone, Ocean) with light/dark modes
• Typography scale (font sizes, line heights)
• Border radius tokens
• Shadow tokens
• CSS variable-based theming system

Structure:

packages/shared-tailwind/
├── package.json
├── src/
│   ├── index.js           # Main exports
│   ├── preset.js          # Tailwind preset with all tokens
│   ├── colors.js          # Color definitions (4 themes)
│   ├── theme-variables.css # CSS variables for themes
│   └── components.css     # Component utilities

Apps using this:

• Memoro Web (full migration with theme.css + components.css)
• Mana Web (preset only, keeps local colors)
• Cards Web (colors import, HSL-based system)
• Maerchenzauber Web (dependency added)

---

4. Shared Utilities (@mana/shared-utils)

Status: Done Priority: Medium Estimated LOC Savings: 200-400 per app

Utilities included:

• date.ts - formatDate, formatRelativeTime, toISOString
• format.ts - formatDuration, formatFileSize, formatNumber, formatCurrency, formatPercent
• validation.ts - isValidEmail, isValidUrl, isValidPhone, validatePassword, isValidUuid
• string.ts - truncate, capitalize, generateId, slugify
• async.ts - sleep, retry, debounce

---

5. Shared Types (@mana/shared-types)

Status: Planned Priority: Medium Estimated Benefit: Type safety across packages

Types to unify:

• User - Common user type
• ApiResponse<T> - Standard API response wrapper
• PaginatedResponse<T> - Pagination types
• Theme - Theme configuration types
• Locale - i18n locale types

Note: App-specific database types (Supabase generated) should remain in each app.

---

6. Shared i18n (@mana/shared-i18n)

Status: Done Priority: Medium Estimated LOC Savings: 100-300 per app

Modules to unify:

• i18n.ts - svelte-i18n setup and initialization
• detectLocale.ts - Browser language detection
• Common translations:
  • Error messages
  • UI labels (Save, Cancel, Delete, etc.)
  • Date/time formats
  • Validation messages

Structure:

packages/shared-i18n/
├── package.json
├── src/
│   ├── index.ts
│   ├── setup.ts
│   ├── detectLocale.ts
│   └── translations/
│       ├── common/
│       │   ├── en.json
│       │   └── de.json
│       └── errors/
│           ├── en.json
│           └── de.json

7. Shared Config (@mana/shared-config)

Status: Planned Priority: Low Estimated Benefit: Consistent env handling

Config to unify:

• Environment variable validation (Zod schemas)
• API endpoint construction
• Feature flag utilities
• App metadata (version, name, etc.)

---

Guidelines for Shared Packages

Package Structure

packages/shared-{name}/
├── package.json
├── tsconfig.json
├── src/
│   ├── index.ts        # Public exports
│   └── ...
└── README.md

Package.json Template

{
	"name": "@mana/shared-{name}",
	"version": "0.1.0",
	"private": true,
	"type": "module",
	"main": "./src/index.ts",
	"types": "./src/index.ts",
	"exports": {
		".": "./src/index.ts"
	},
	"peerDependencies": {
		"svelte": "^5.0.0"
	}
}

Best Practices

1. Keep it minimal - Only share truly common code
2. Document props - Use TypeScript interfaces with JSDoc
3. Version carefully - Coordinate updates across apps
4. Test thoroughly - Changes affect all apps
5. Avoid breaking changes - Use deprecation warnings
