Suggestions to improve your current code:

[DevKelbs]

1. Organize your client-side JavaScript code: Right now, you have a single game.js file that includes various parts of your application logic. It would be better to organize your code into separate modules. For example, you could have separate files for authentication, character creation, character selection, and game logic. This way, your code will be more modular and easier to maintain.

2. Add comments and documentation: Adding comments and documentation to your code can significantly improve its readability and maintainability. It's important to document your functions, components, and routes to make it easier for others to understand and contribute to your project.

3. Handle user input validation: In your auth.js file, you're currently not validating user input. It would be a good idea to add validation checks to make sure the user provides the required information during registration and login. This will help prevent unexpected issues caused by missing or invalid input data.

4. Improve error handling: Ensure that you handle errors gracefully throughout your application. For example, when an error occurs during the character creation process, you should show an appropriate error message to the user instead of letting the app fail silently.

5. UI/UX improvements: While the functionality of your application is the priority, you might want to consider improving the user interface and user experience. A well-designed, user-friendly interface can significantly enhance the overall experience of your game.

6. Use environment variables for sensitive information: You should avoid hardcoding sensitive information, such as the JWT secret, in your code. Instead, store this information in environment variables and use a package like dotenv to access these variables in your application.

7. Create unit tests: As your application grows in complexity, it's important to create unit tests to ensure the correct behavior of your application logic. Writing tests can help you catch bugs and ensure the reliability of your code as you make changes.

8. Consider using a frontend framework: As your application becomes more complex, you might find it helpful to use a frontend framework such as React, Vue.js, or Angular to better structure your code and make it easier to maintain and scale your project.

1. Completed. Split game.js into main, auth, ui, and player. main.js is the new game.js.

2. Completed. Will work on commenting throughout continued development.

3. Completed. Created a separate utility function to validate the email address format:

// Add this function to the top of your auth.js file

function isValidEmail(email) {
const emailRegex = /^[\w-]+(\.[\w-]+)*@([\w-]+\.)+[a-zA-Z]{2,7}$/;
return emailRegex.test(email);
}

// Add this function to the top of your auth.js file

function validateUserInput(username, email, password, passwordConfirm) {
const errors = [];

if (!username || username.trim().length === 0) {
errors.push('Username is required');
}

if (!email || !isValidEmail(email)) {
errors.push('A valid email address is required');
}

if (!password || password.trim().length === 0) {
errors.push('Password is required');
}

if (password !== passwordConfirm) {
errors.push('Passwords do not match');
}

return errors;
}

4. Completed. I added a displayErrorMessage function to display error messages to the user. When an error occurs during character creation, this function is called to show an appropriate error message.
