[Tijo-11]

📌 Pull Request Description

Summary of Changes

This PR modernizes the portfolio project to be fully compatible with React 19 and Vite while also standardizing the package manager to npm.

---

⚡️ Build Tool & Setup

• Migrated from CRA/Webpack to Vite for faster builds and dev server.
• Fixed stricter import resolution issues under Vite.

---

🎨 UI Library Updates

• Material-UI v4 → MUI v5

  • Replaced @material-ui/core & @material-ui/icons with @mui/material and @mui/icons-material.
  • Migrated from makeStyles (deprecated) to styled from @mui/material/styles or the sx prop.

---

🎬 Animation & Effects

• Replaced react-reveal (not React 18/19 safe) with framer-motion (<Fade> → <motion.div>).
• Replaced react-fast-marquee with a custom framer-motion marquee for smoother animations.

---

🧭 Routing

• Upgraded to react-router-dom v6.
• Replaced NavHashLink with react-router-hash-link (v2, v6 compatible).
• Updated Route/Switch logic for v6 APIs.

---

🧠 Context & State

• Modernized ThemeContext:

  • Removed outdated setHandleDrawer.
  • Added toggleDrawer with useCallback.
  • Used useMemo for context values.
  • Defined default context shape to avoid undefined values.

---

📦 Dependencies

• Replaced outdated libraries:

  • react-helmet → react-helmet-async.
  • @material-ui/core/Drawer → @mui/material/Drawer.

• Considered alternatives for react-slick (e.g., Swiper.js).

---

📝 Components Updated

• Updated key components (Navbar, Projects, SingleProject, Blog, EducationCard, AchievementCard, etc.) to:

  • Remove makeStyles usage.
  • Replace Fade with framer-motion.
  • Fix broken imports from old packages.
  • Ensure consistent use of theme from ThemeContext.

📌 Package Manager

• Standardized on npm:

  • Updated and committed package-lock.json.

---

✅ Result:
The project is now React 19 + Vite compatible, using MUI v5 + framer-motion for modern UI/animations, with a simplified dependency tree and standardized package management via npm.
