    try:
        data = request.get_json()
        
        # Validate required fields
        if not all(k in data for k in ('username', 'email', 'password')):
            return jsonify({'error': 'Missing required fields'}), 400
        
        # Email validation
        if not re.match(r'^[\w\.-]+@[\w\.-]+\.\w+$', data['email']):
            return jsonify({'error': 'Invalid email format'}), 400
        
        # Password strength check
        if len(data['password']) < 8:
            return jsonify({'error': 'Password must be at least 8 characters'}), 400
        
        # Hash password and save user (implementation depends on your database)
