Full-Stack Intern Task – CodeIgniter 4 + React (JWT)

This repo contains:

• backend-ci4/ – CodeIgniter 4 API with JWT auth (register, login, teachers list)
• frontend-react-vite/ – React app (Register, Login, Teachers datatable)
• db/intern_task_mysql_dump.sql – MySQL schema dump

Backend (CodeIgniter 4)

Requirements: PHP >= 8.0, Composer, MySQL (or MariaDB)

cd backend-ci4
cp .env.example .env
# edit .env with your DB credentials and JWT secret
composer install
# Create database using the SQL dump first:
mysql -u root -p < ../db/intern_task_mysql_dump.sql
# Start API
php spark serve

Endpoints:

• POST /api/register – creates auth_user and teachers in one request, returns JWT

  {
    "email": "a@b.com",
    "password": "Pass@123",
    "first_name": "Ada",
    "last_name": "Lovelace",
    "university_name": "Babbage Univ",
    "gender": "Female",
    "year_joined": 2020
  }

• POST /api/login – returns JWT
• GET /api/teachers – protected, Authorization: Bearer <token>

Frontend (React + Vite)

Requirements: Node 18+

cd frontend-react-vite
cp .env.example .env
npm install
npm run dev

Notes

• Passwords are hashed with password_hash (bcrypt).
• JWT via firebase/php-jwt.
• One-to-one relation is enforced by teachers.user_id UNIQUE + FK.
• Change VITE_API_BASE to point to your backend base URL.
