Pull Request Overview

This PR transforms the React template application into a functional login and data display application. The implementation adds authentication functionality with a custom hook, a login form with validation, and a data table component that fetches and displays album data from the JSONPlaceholder API. The styling has been completely redesigned with custom CSS using the Poppins font family and a consistent dark color scheme (#333).

Key Changes

• Added authentication system with useAuth custom hook and LoginForm component with client-side validation
• Implemented DataTable component with pagination ("load more") functionality and API integration using axios
• Replaced default styling with custom CSS featuring Poppins font, responsive design, and smooth animations

Missing input validation for username and password parameters. The login function doesn't validate that the parameters are strings or handle null/undefined values, which could lead to unexpected behavior.

Add parameter validation:

const login = async (username, password) => {
  if (!username || !password || typeof username !== 'string' || typeof password !== 'string') {
    setError('Invalid credentials provided');
    return false;
  }
  // ... rest of implementation
};

The error message "Error al cargar los datos." is generic and doesn't provide useful debugging information to users or developers. The actual error is logged to console but not communicated to the user.

Consider making the error message more informative:

setError(`Error al cargar los datos: ${err.message || 'Por favor, intente nuevamente.'}`);

Or provide different messages based on error type (network error, timeout, etc.).

Suggested change

	setError('Error al cargar los datos.');
	setError(`Error al cargar los datos: ${err.message || 'Por favor, intente nuevamente.'}`);

[nitpick] Missing PropTypes validation. The component accepts props but doesn't validate their types using PropTypes, which is a React best practice for catching bugs during development.

Add PropTypes validation:

import PropTypes from 'prop-types';

LoginForm.propTypes = {
  onLogin: PropTypes.func.isRequired,
  isLoading: PropTypes.bool.isRequired,
  error: PropTypes.string
};

The useEffect has an empty dependency array but calls fetchAlbums, which is defined in the component scope. While this works, it violates the React Hooks exhaustive-deps rule. The fetchAlbums function should either be included in the dependency array or wrapped with useCallback.

Recommended fix using useCallback:

const fetchAlbums = useCallback(async () => {
  setIsLoading(true);
  setError('');
  // ... rest of implementation
}, []);

useEffect(() => {
  fetchAlbums();
}, [fetchAlbums]);

Inconsistent spacing in comment. The comment has irregular spacing with two spaces after "//".

Change to:

// Cierre de sesión

Suggested change

	// Cierre de sesión
	// Cierre de sesión

[nitpick] The transition duration for .load-more-button:hover is 0.5s, which is significantly longer than other hover transitions in the file (which use 0.2s). This creates an inconsistent user experience.

For consistency with other buttons in the application, change to:

.load-more-button {
  /* ... */
  transition: all 0.2s ease;
}

Suggested change

	transition: all 0.5s ease;
	transition: all 0.2s ease;

Empty ruleset with no properties. The .login-card selector has a closing brace on line 18 but no additional properties are defined between the padding: 40px; on line 16 and the closing brace, suggesting this empty line may be unnecessary or left for future additions.

Remove the empty line to improve code cleanliness, or if properties are planned to be added here, add a TODO comment.

[nitpick] Missing JSDoc documentation for the component. The LoginForm component accepts props (onLogin, isLoading, error) but lacks documentation describing:

• The purpose of the component
• The expected prop types and their descriptions
• The expected behavior of the onLogin callback

Consider adding JSDoc documentation:

/**
 * LoginForm component for user authentication
 * @param {Object} props - Component props
 * @param {Function} props.onLogin - Callback function called with (username, password) on form submission
 * @param {boolean} props.isLoading - Indicates if authentication is in progress
 * @param {string} props.error - Error message to display, if any
 */

Suggested change

	/**
	* LoginForm component for user authentication.
	* Renders a login form and handles user input validation.
	*
	* @param {Object} props - Component props
	* @param {Function} props.onLogin - Callback function called with (username, password) on form submission
	* @param {boolean} props.isLoading - Indicates if authentication is in progress
	* @param {string} props.error - Error message to display, if any

[nitpick] Duplicate color value #333 is used multiple times throughout the stylesheet (lines 19, 26, 51, 80, 102, 128, 135, 173). Consider defining this as a CSS custom property (variable) for better maintainability:

:root {
  --primary-dark: #333;
}

This makes it easier to maintain a consistent color scheme and update colors across the application.

[nitpick] Missing JSDoc documentation for the custom hook. The useAuth hook lacks documentation describing:

• The purpose of the hook
• Return value structure and types
• Usage examples

Consider adding JSDoc documentation:

/**
 * Custom hook for managing authentication state
 * @returns {Object} Authentication state and methods
 * @returns {boolean} return.isAuthenticated - Whether user is authenticated
 * @returns {boolean} return.isLoading - Whether authentication is in progress
 * @returns {string} return.error - Error message, if any
 * @returns {Function} return.login - Login function that accepts (username, password)
 * @returns {Function} return.logout - Logout function
 */

Suggested change

	// Custom hook para manejar la autenticación
	/**
	* Custom hook for managing authentication state.
	*
	* @returns {Object} Authentication state and methods
	* @returns {boolean} return.isAuthenticated - Whether user is authenticated
	* @returns {boolean} return.isLoading - Whether authentication is in progress
	* @returns {string} return.error - Error message, if any
	* @returns {Function} return.login - Login function that accepts (username, password)
	* @returns {Function} return.logout - Logout function
	*
	* @example
	* const { isAuthenticated, isLoading, error, login, logout } = useAuth();
	* // Use these values and functions in your component
