(cover a range of skills and concepts, providing practical experience in database design, SQL, and web integration. Adjust the difficulty based on the students' progress throughout the course)
- Design a database schema for my online learning website.
- Implement a SQL query to retrieve data from multiple related tables.
- Connect a web application (using a chosen server-side language) to a database.
- Optimize a slow-performing SQL query.
- Set up user authentication and authorization for a web application.
Example: Using Node.js with Express.
- Choose a database (e.g., MongoDB for flexibility).
- Set up a connection and create necessary collections (e.g., courses, users).
// Example with MongoDB and Mongoose
const mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/learning_platform', { useNewUrlParser: true, useUnifiedTopology: true });
- Implement user authentication for secure access
// Example with Passport.js
const passport = require('passport');
const LocalStrategy = require('passport-local').Strategy;
passport.use(new LocalStrategy(
(username, password, done) => {
// Validate user credentials
// Call done() with user object if authenticated
}
));
- Create endpoints for CRUD operations on courses, user profiles, etc.
// Example API endpoint for fetching courses
app.get('/api/courses', (req, res) => {
// Retrieve and send course data from the database
});
Example: Using React.js for a dynamic user interface.
Display a list of available courses.
// Example React component
function CourseList({ courses }) {
return (
<div>
<h2>Available Courses</h2>
<ul>
{courses.map(course => (
<li key={course.id}>{course.title}</li>
))}
</ul>
</div>
);
}
- Create login and registration forms
// Example React component for login form
function LoginForm() {
return (
<form>
<label>Username:</label>
<input type="text" />
<label>Password:</label>
<input type="password" />
<button type="submit">Login</button>
</form>
);
}
- Display detailed information about a selected course.
// Example React component for course details
function CourseDetails({ course }) {
return (
<div>
<h2>{course.title}</h2>
<p>{course.description}</p>
</div>
);
}
- Fetch data from backend API endpoints and update the UI.
// Example React component fetching courses from the backend
function CourseList() {
const [courses, setCourses] = useState([]);
useEffect(() => {
// Fetch courses from the backend
fetch('/api/courses')
.then(response => response.json())
.then(data => setCourses(data))
.catch(error => console.error('Error fetching courses:', error));
}, []);
return (
// Render the course list UI
);
}
One needs to handle more aspects like user authentication flow, error handling, and styling. Additionally, incorporating a state management library (e.g., Redux for React) and using proper security practices is crucial for a production-ready application.
