Review Summary

Your implementation is missing approximately 90% of the required functionality. Only the most basic registration endpoint exists, but critical authentication features are completely absent: - Password validation: No logic to validate against required rules (min length, special characters, etc.) and users aren't informed about these rules. Additionally, passwords are stored as plain text instead of being hashed with bcrypt. - Activation flow: No isActive field in the User model, no activation token generation, no email sending, and no /activate route. - All authentication routes: Missing login (/login), logout (/logout), password reset (request + confirmation + success), and profile (/profile) endpoints. - Authentication middleware: No middleware to protect routes (profile/logout should require auth; login/registration should be for non-authenticated users only). - 404 handler: No catch-all handler for undefined routes as required by the task. Also fix this blocker: Your .eslintrc.js uses CommonJS syntax (module.exports) but package.json has `

Missing password validation. Requirements state you must inform users about password rules and check/validate against them. Add validation logic (e.g., min length, special characters) before creating the user.

The + '' on password is unnecessary - process.env.DB_PASSWORD is already a string. This could be simplified to just password: process.env.DB_PASSWORD.

There is a minor issue in the email change flow.

When the user opens the email change confirmation link, the email is successfully updated and the backend correctly returns status 200. However, after that, an additional refresh/auth request is triggered automatically, which causes confirmEmailChange to run again with the same token. Since the token has already been cleared after the first successful confirmation, the second request results in User not found.

The main functionality works correctly, but there is still an edge-case issue related to repeated requests after the confirmation flow.

Review Summary

Your implementation covers most authentication features well, but two critical requirements from the task are not met:

Missing 404 catch-all handler: The task explicitly requires "404 for all the other pages" but src/backend/src/index.js has no catch-all route like app.use((req, res) => res.status(404).send({ message: 'Not found' })) to handle undefined endpoints.
Missing password rules display: The task explicitly requires "Inform the users about the rules for a password and check them", but the registration page never shows password requirements (minimum length, special characters, uppercase, etc.). Users must guess what constitutes a valid password.

Additionally, these medium issues should be addressed:

src/backend/src/controllers/profile.controller.js line 85: missing await before user.save() causing potential race conditions
src/backend/src/pages/ActivationPage.tsx: navigate('/profile') is called before the activation promise resolves, causing premature navigation
src/frontend/src/pages/ProfilePage/components/ProfileChangePassword.tsx line 68: h3 heading says "Change email" but should say "Change password"
Backend's changePassword endpoint doesn't validate password confirmation (should check newPassword === confirmation)

The linting failure in check runs is due to ESLint configuration issues (flat config vs deprecated flags), not your code. Once the missing 404 handler and password rules display are added, the implementation should meet all task requirements.

The import path './src/models/user.js' is incorrect. Since setup.js is already in 'src/backend/', the correct path should be './models/user.js'. This same issue applies to other imports in this file.

Add app.use((req, res) => res.status(404).send({ message: 'Not found' })) before the error middleware and after other routes to handle requests to non-existent endpoints.

Missing isActive field: The task mentions checking if user is active and redirecting them if not. The User model doesn't have an explicit isActive boolean field - it uses activationToken being null to indicate active status. This works, but consider if an explicit isActive field would be clearer.

Missing password rules: The password validation only checks for minimum length (6 characters). The task requires informing users about password rules and validating against them. Consider adding validation for special characters, uppercase letters, etc., and the frontend should display these rules to users during registration.

Missing password rules display: The task requires informing users about password rules during registration. The registration page only shows validation errors but doesn't display what the password rules are (e.g., minimum length, special characters, uppercase).

Inconsistent error handling: The login function (line 48-64) doesn't have a final throw new Error for non-Axios errors, unlike other functions. If a non-Axios error occurs, the function silently returns undefined. Consider adding: throw new Error('Unknown error', { cause: error });

Missing 404 handler: The task explicitly requires '404 for all the other pages'. While the frontend has a NotFoundPage, the backend index.js needs a catch-all route to return 404 for undefined endpoints: app.use((req, res) => res.status(404).send({ message: 'Not found' }))

The changePassword function only sends currentPassword and newPassword but the task requires 'new password and confirmation'. The frontend should also collect and send confirmation field, and validate that newPassword === confirmation before making the API call.

Inconsistent error handling: The logout function (lines 66-77) doesn't throw an error for non-Axios errors (the catch block only handles Axios errors). Other functions like login have the same issue. Consider adding a generic error throw in the catch block.

Missing password confirmation in API: The changePassword function sends currentPassword and newPassword, but the task requires a confirmation field. The backend should also validate the confirmation. Consider adding a confirmPassword parameter and validating it matches newPassword.

Navigation timing issue: The navigate('/profile') call on line 26 happens immediately after starting the activation promise, not after it resolves. This means the user navigates to profile before the activation actually completes. Move navigate inside a .then() block after the activation completes, or call it only in the .finally() block after setting done to true.

Throwing in useEffect: The throw new Error('Error') in the catch block inside useEffect (line 20) is problematic. Throwing errors in effects can cause React warnings and unexpected behavior. Instead of throwing, consider logging the error or setting a state to display an error message to the user.

Error handling in useEffect: Throwing an error inside a useEffect callback (line 20) is problematic. The error won't be caught by React error boundaries and will crash the app. Consider handling the error differently, such as setting an error state instead of throwing.

Navigation timing issue: The navigate('/profile') on line 26 is called before the activation promise resolves. This means the user navigates to profile even if activation fails. Move the navigation inside .then() after setUser() to ensure it only happens on success.

Missing password rules display: The reset password page should also inform users about password rules when they set a new password.

+  newPassword: string,


Missing confirmPassword field: The ConfirmNewPasswordData type only has resetToken and newPassword. The task requires validating that 'password and confirmation fields must be equal'. Add confirmPassword: string to the type definition.

Sensitive data exposure: The User interface (lines 1-6) includes password and activationToken fields which are sensitive server-side data. This interface shouldn't be exported or used on the frontend. The ProfileUser interface is sufficient for client-side use.

Review Summary

Your implementation covers most authentication features well, but two critical requirements from the task are not met:

Missing 404 catch-all handler: The task explicitly requires "404 for all the other pages" but src/backend/src/index.js has no catch-all route like app.use((req, res) => res.status(404).send({ message: 'Not found' })) to handle undefined endpoints.
Missing password rules display: The task explicitly requires "Inform the users about the rules for a password and check them", but the registration page never shows password requirements (minimum length, special characters, uppercase, etc.). Users must guess what constitutes a valid password.

Additionally, these medium issues should be addressed:

src/backend/src/controllers/profile.controller.js line 85: missing await before user.save() causing potential race conditions
src/backend/src/pages/ActivationPage.tsx: navigate('/profile') is called before the activation promise resolves, causing premature navigation
src/frontend/src/pages/ProfilePage/components/ProfileChangePassword.tsx line 68: h3 heading says "Change email" but should say "Change password"
Backend's changePassword endpoint doesn't validate password confirmation (should check newPassword === confirmation)

The linting failure in check runs is due to ESLint configuration issues (flat config vs deprecated flags), not your code. Once the missing 404 handler and password rules display are added, the implementation should meet all task requirements.

Missing password rules display: The task requires informing users about password rules during registration. The registration page only shows validation errors but doesn't display what the password rules are (e.g., minimum length, special characters, uppercase).

Inconsistent error handling: The login function (line 48-64) doesn't have a final throw new Error for non-Axios errors, unlike other functions. If a non-Axios error occurs, the function silently returns undefined. Consider adding: throw new Error('Unknown error', { cause: error });

Missing 404 handler: The task explicitly requires '404 for all the other pages'. While the frontend has a NotFoundPage, the backend index.js needs a catch-all route to return 404 for undefined endpoints: app.use((req, res) => res.status(404).send({ message: 'Not found' }))

The useEffect dependency array is missing navigate which could cause React warnings about missing dependencies. Consider adding navigate to the dependency array or using useCallback for the effect.

The changePassword function only sends currentPassword and newPassword but the task requires 'new password and confirmation'. The frontend should also collect and send confirmation field, and validate that newPassword === confirmation before making the API call.

Inconsistent error handling: The logout function (lines 66-77) doesn't throw an error for non-Axios errors (the catch block only handles Axios errors). Other functions like login have the same issue. Consider adding a generic error throw in the catch block.

Missing password confirmation in API: The changePassword function sends currentPassword and newPassword, but the task requires a confirmation field. The backend should also validate the confirmation. Consider adding a confirmPassword parameter and validating it matches newPassword.

Navigation timing issue: The navigate('/profile') call on line 26 happens immediately after starting the activation promise, not after it resolves. This means the user navigates to profile before the activation actually completes. Move navigate inside a .then() block after the activation completes, or call it only in the .finally() block after setting done to true.

Throwing in useEffect: The throw new Error('Error') in the catch block inside useEffect (line 20) is problematic. Throwing errors in effects can cause React warnings and unexpected behavior. Instead of throwing, consider logging the error or setting a state to display an error message to the user.

Error handling in useEffect: Throwing an error inside a useEffect callback (line 20) is problematic. The error won't be caught by React error boundaries and will crash the app. Consider handling the error differently, such as setting an error state instead of throwing.

Missing 404 catch-all handler: The task explicitly requires "404 for all the other pages" but src/backend/src/index.js has no catch-all route like app.use((req, res) => res.status(404).send({ message: 'Not found' })) to handle undefined endpoints.
Missing password rules display: The task explicitly requires "Inform the users about the rules for a password and check them", but the registration page never shows password requirements (minimum length, special characters, uppercase, etc.). Users must guess what constitutes a valid password.

Additionally, these medium issues should be addressed:

src/backend/src/controllers/profile.controller.js line 85: missing await before user.save() causing potential race conditions
src/backend/src/pages/ActivationPage.tsx: navigate('/profile') is called before the activation promise resolves, causing premature navigation
src/frontend/src/pages/ProfilePage/components/ProfileChangePassword.tsx line 68: h3 heading says "Change email" but should say "Change password"
Backend's changePassword endpoint doesn't validate password confirmation (should check newPassword === confirmation)

The linting failure in check runs is due to ESLint configuration issues (flat config vs deprecated flags), not your code. Once the missing 404 handler and password rules display are added, the implementation should meet all task requirements.

The import path './src/models/user.js' is incorrect. Since setup.js is already in 'src/backend/', the correct path should be './models/user.js'. This same issue applies to other imports in this file.

The auth routes (registration, login, password reset) should only be accessible to non-authenticated users. The backend doesn't implement middleware to check if a user is already authenticated and redirect them.

Missing 404 handler: There is no catch-all route handler for undefined pages. The task explicitly requires '404 for all the other pages'. Add app.use((req, res) => res.status(404).send({ message: 'Not found' })) before the error middleware and after other routes to handle requests to non-existent endpoints.

The task requires changing password with 'old one, new password and confirmation'. The backend only accepts currentPassword and newPassword but does not require or validate confirmation. The backend should also validate that newPassword === confirmation before updating.

Missing isActive field: The task mentions checking if user is active and redirecting them if not. The User model doesn't have an explicit isActive boolean field - it uses activationToken being null to indicate active status. This works, but consider if an explicit isActive field would be clearer.

Missing 404 handler: The task explicitly requires '404 for all the other pages'. While the frontend has a NotFoundPage, the backend index.js needs a catch-all route to return 404 for undefined endpoints: app.use((req, res) => res.status(404).send({ message: 'Not found' }))

The useEffect dependency array is missing navigate which could cause React warnings about missing dependencies. Consider adding navigate to the dependency array or using useCallback for the effect.

+  currentPassword: string,

+      cause: error,

The changePassword function only sends currentPassword and newPassword but the task requires 'new password and confirmation'. The frontend should also collect and send confirmation field, and validate that newPassword === confirmation before making the API call.

Missing password rules display: The task requires informing users about password rules. The registration page doesn't display what the password requirements are (minimum length, special characters, etc.). Add a helper text or list showing the password requirements near the password field.

+      throw new Error(error.response?.data.message || 'Logout failed', {
+        cause: error,
+      });
+    }
+  }


Inconsistent error handling: The logout function (lines 66-77) doesn't throw an error for non-Axios errors (the catch block only handles Axios errors). Other functions like login have the same issue. Consider adding a generic error throw in the catch block.

Missing password confirmation in API: The changePassword function sends currentPassword and newPassword, but the task requires a confirmation field. The backend should also validate the confirmation. Consider adding a confirmPassword parameter and validating it matches newPassword.

Navigation timing issue: The navigate('/profile') call on line 26 happens immediately after starting the activation promise, not after it resolves. This means the user navigates to profile before the activation actually completes. Move navigate inside a .then() block after the activation completes, or call it only in the .finally() block after setting done to true.

Throwing in useEffect: The throw new Error('Error') in the catch block inside useEffect (line 20) is problematic. Throwing errors in effects can cause React warnings and unexpected behavior. Instead of throwing, consider logging the error or setting a state to display an error message to the user.

+type Props = {
+  children: React.ReactNode;

Error handling in useEffect: Throwing an error inside a useEffect callback (line 20) is problematic. The error won't be caught by React error boundaries and will crash the app. Consider handling the error differently, such as setting an error state instead of throwing.

Navigation timing issue: The navigate('/profile') on line 26 is called before the activation promise resolves. This means the user navigates to profile even if activation fails. Move the navigation inside .then() after setUser() to ensure it only happens on success.

Missing password rules display: The reset password page should also inform users about password rules when they set a new password.

+export type ConfirmNewPasswordData = {
+  resetToken: string,
+  newPassword: string,


Missing confirmPassword field: The ConfirmNewPasswordData type only has resetToken and newPassword. The task requires validating that 'password and confirmation fields must be equal'. Add confirmPassword: string to the type definition.

+export type FormErrors = {
+  name: string;
+  email: string;
+  password: string;

Sensitive data exposure: The User interface (lines 1-6) includes password and activationToken fields which are sensitive server-side data. This interface shouldn't be exported or used on the frontend. The ProfileUser interface is sufficient for client-side use.

Review Summary

Your solution is approved. All previously identified issues have been successfully resolved: the 404 catch-all handler is properly implemented, password rules are displayed via tooltip on registration and reset password pages, all await keywords are correctly placed before user.save() calls, the ActivationPage awaits the promise before navigation, and password confirmation validation works in both frontend and backend. The only check run failure is a tooling issue with ESLint's --ext flag incompatibility in the mate-scripts package—this is unrelated to your code quality. Excellent work implementing all authentication features including registration with activation, login/logout, password reset, and profile management with name, password, and email changes.
