Verification Checklist:

+
    +
  • ✓ Open DevTools → Application → Local Storage → http://localhost:3000
  • +
  • ✓ Interact with the controls above and watch localStorage update in real-time
  • +
  • ✓ Refresh the page (F5) - all values should persist
  • +
  • ✓ Check Console for hydration errors (there should be none)
  • +
  • ✓ Check Console for any errors (there should be none)
  • +
  • ✓ Verify TypeScript has no errors in your editor

Test Your Changes +```bash +# Run development server +npm run dev + +# Run linter +npm run lint + +# Run tests +npm test +``` + +### 4. Build for Production +```bash +npm run build +``` + +Ensure the build completes without errors before submitting. + +## Code Style & Standards + +### TypeScript +- Use TypeScript for all new files +- Define proper types and interfaces +- Avoid using `any` - use proper typing or `unknown` +- Export types from a central `types/` directory when shared + +### React Components +- Use functional components with hooks +- Follow the component structure: + 1. Imports + 2. Type definitions + 3. Component definition + 4. Helper functions (if needed) + 5. Exports + +Example: +```typescript +import { useState } from 'react'; +import { Button } from '@/components/ui/Button'; + +interface MyComponentProps { + title: string; + onSubmit: () => void; +} + +export function MyComponent({ title, onSubmit }: MyComponentProps) { + const [isLoading, setIsLoading] = useState(false); + + const handleClick = async () => { + setIsLoading(true); + await onSubmit(); + setIsLoading(false); + }; + + return ( +
+

{title}

+ +
+ ); +} +``` + +### Styling +- Use Tailwind CSS utility classes +- Use `cn()` utility from `tailwind-merge` to merge classes +- Follow the mobile-first responsive design approach +- Use CSS variables for theme colors (defined in `globals.css`) + +### File Naming +- Components: PascalCase (e.g., `MyComponent.tsx`) +- Utilities: camelCase (e.g., `formatDate.ts`) +- Pages: lowercase (e.g., `page.tsx`, `layout.tsx`) +- Types: PascalCase with `.types.ts` suffix (e.g., `User.types.ts`) + +### Import Organization +```typescript +// 1. External dependencies +import { useState } from 'react'; +import { useTranslations } from 'next-intl'; + +// 2. Internal components and utilities +import { Button } from '@/components/ui/Button'; +import { formatDate } from '@/utils/date'; + +// 3. Types +import type { User } from '@/types/User.types'; + +// 4. Styles (if any) +import styles from './Component.module.css'; +``` + +### Internationalization +- All user-facing text must be internationalized +- Use `useTranslations()` hook from `next-intl` +- Add translation keys to all language files in `src/messages/` + +Example: +```typescript +import { useTranslations } from 'next-intl'; + +export function WelcomeMessage() { + const t = useTranslations('home'); + + return

{t('welcome')}

; +} +``` + +## Testing + +### Unit Tests +- Write tests for utility functions and complex logic +- Use Vitest as the testing framework +- Place test files next to the code they test with `.test.ts` or `.test.tsx` extension + +Example: +```typescript +// formatDate.test.ts +import { describe, it, expect } from 'vitest'; +import { formatDate } from './formatDate'; + +describe('formatDate', () => {

Verify Your Changes + +1. **Build the application** to ensure no TypeScript errors: + ```bash + npm run build + ``` + +2. **Test in all three languages:** + - German: `http://localhost:3000/de` + - English: `http://localhost:3000/en` + - Serbian: `http://localhost:3000/sr` + +3. **Check for missing translations** - The browser console will warn if a key is missing + +#### JSON Structure & Organization + +##### Hierarchical Namespace Pattern + +Translation files use a **deeply nested JSON structure** to organize translations logically: + +```json +{ + "namespace": { // Top-level category + "subnamespace": { // Feature or section + "key": "value", // Leaf node (actual translation) + "nested": { + "key": "value" // Deeper nesting allowed + } + } + } +} +``` + +**Real example from the codebase:** + +```json +{ + "pages": { // Namespace: Page content + "home": { // Subnamespace: Homepage + "hero": { // Section: Hero section + "title": "FULLSTACK DEVELOPER", + "subtitle": "AI AGENTS | VOICE AI", + "navigation": { // Nested object + "experience": "EXPERIENCE", + "skills": "SKILLS" + } + } + } + } +} +``` + +**Access in code:** + +```tsx +const t = useTranslations('pages.home.hero'); +console.log(t('title')); // "FULLSTACK DEVELOPER" +console.log(t('navigation.experience')); // "EXPERIENCE" +``` + +##### Special Data Types + +**Arrays** - For lists of items: + +```json +{ + "meta": { + "site": { + "keywords": [ + "Fullstack Developer", + "AI Developer Germany", + "Process Automation" + ] + } + } +} +``` + +**Usage:** + +```tsx +const t = useTranslations('meta.site'); +const keywords = t.raw('keywords'); // Returns array +``` + +**Objects** - For structured data: + +```json +{ + "pages": { + "home": { + "experience": { + "positions": [ + { + "role": "Process Automation Specialist", + "company": "Everlast Consulting GmbH", + "period": "12/2024 - PRESENT", + "highlights": [ + "Development of AI agents", + "Web scraping solutions" + ] + } + ] + } + } + } +} +``` + +**Usage:** + +```tsx +const t = useTranslations('pages.home.experience'); +const positions = t.raw('positions'); // Returns array of objects + +positions.map((position) => ( +
+

{position.role}

+

{position.company}

+ {position.period} +
    + {position.highlights.map((highlight) => ( +
  • {highlight}
  • + ))} +
+
+)); +``` + +#### Advanced Usage Examples + +##### Dynamic Translation Keys + +Access translations dynamically based on variables: + +```tsx +import { useTranslations } from 'next-intl'; + +export default function CategoryFilter({ categories }: { categories: string[] }) { + const t = useTranslations('portfolio.filters.categories'); + + return ( +
+ {categories.map((category) => ( + + ))} +
+ ); +} + +// If categories = ["Data Science", "AI Development"] +// Output: "Data Science" → "Data Science" (en) or "Data Science" (de) +// "AI Development" → "AI Development" (en) or "KI-Entwicklung" (de) +``` + +##### String Interpolation + +Use variables in translations: + +```tsx +import { useTranslations } from 'next-intl'; + +export default function Pagination({ start, end, total }: PaginationProps) { + const t = useTranslations('blog.ui.pagination'); + + // Translation: "Showing {start}-{end} of {total} articles" + return ( +

+ {t('showing', { start, end, total })} +

+ ); +} +``` + +**In JSON:** + +```json +{ + "blog": { + "ui": { + "pagination": { + "showing": "Showing {start}-{end} of {total} articles" + } + } + } +} +``` + +##### Accessing Rich Content + +For translations containing HTML or rich content: + +```tsx +import { useTranslations } from 'next-intl'; + +export default function RichText() { + const t = useTranslations('pages.about'); + + return ( +
+ {/* Simple text */} +

{t('hero.title')}

+ + {/* Raw access for objects/arrays */} +
+ {t.raw('hero.expertise.processAutomation')} +
+
+ ); +} +``` + +#### Common Patterns & Best Practices + +##### ✅ DO: Keep Structure Consistent + +```json +// Good: Same structure across all locales +// de.json +{ "common": { "actions": { "save": "Speichern" } } } + +// en.json +{ "common": { "actions": { "save": "Save" } } } + +// sr.json +{ "common": { "actions": { "save": "Sačuvaj" } } } +``` + +##### ❌ DON'T: Mix Structures + +```json +// Bad: Different structures +// de.json +{ "common": { "actions": { "save": "Speichern" } } } + +// en.json +{ "common": { "save": "Save" } } // ❌ Missing "actions" level +``` + +##### ✅ DO: Use Semantic Naming + +```json +{ + "common": { + "actions": { + "submit": "Submit", // ✅ Clear, semantic + "cancel": "Cancel", + "delete": "Delete" + } + } +} +``` + +##### ❌ DON'T: Use Generic Names + +```json +{ + "common": { + "button1": "Submit", // ❌ Non-descriptive + "btn": "Cancel", // ❌ Abbreviated + "text1": "Delete" // ❌ Generic + } +} +``` + +##### ✅ DO: Group Related Translations + +```json +{ + "pages": { + "contact": { + "contactForm": { // ✅ Grouped by feature + "title": "Contact Me", + "name": { "label": "Name", "placeholder": "Your name" }, + "email": { "label": "Email", "placeholder": "your@email.com" }, + "submit": "Send Message" + } + } + } +} +``` + +##### ✅ DO: Reuse Common Translations + +```tsx +// Good: Reuse common translations +import { useTranslations } from 'next-intl'; + +export default function MyForm() { + const tCommon = useTranslations('common.actions'); + + return ( +
