PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

🎫 Ticket compliance analysis ❌ 4 - Not compliant Compliant requirements: None of the requirements are met by this PR Non-compliant requirements: Update and manage dependencies in the project Handle deprecated dependencies Update React and React Native related packages Update Expo related packages

⏱️ Estimated effort to review: 3 🔵🔵🔵⚪⚪

🧪 No relevant tests

🔒 Security concerns Email verification bypass: The current implementation in both signup.tsx and index.tsx allows navigation to the next screen without proper verification code validation, which could potentially allow users to bypass email verification. The handleVerification functions are empty and need proper implementation of verification logic.

⚡ Recommended focus areas for review Possible Bug The email verification flow might get stuck if the verification code sending fails silently. Need to verify error handling and user feedback Code Smell The handleVerification function is empty with only a comment. The verification logic is missing which could lead to navigation without actual verification Code Smell Similar to index.tsx, the handleVerification function lacks implementation and could allow navigation without proper verification

PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

🎫 Ticket compliance analysis ❌ 4 - Not compliant Compliant requirements: None - this PR implements email verification which is not related to the dependency management ticket Non-compliant requirements: Update and manage dependencies in the project Handle deprecated dependencies Address rate-limited updates Manage open PRs and dependencies

⏱️ Estimated effort to review: 3 🔵🔵🔵⚪⚪

🧪 No relevant tests

🔒 Security concerns Email verification bypass: The verification code handling in both signup.tsx and index.tsx is currently incomplete (marked with TODO comments). Without proper implementation, this could potentially allow users to bypass email verification by directly navigating to the next screen.

⚡ Recommended focus areas for review Error Handling The email verification error handling might not cover all edge cases, such as network errors or timeouts during verification code sending Code Smell The verification code handling is marked with a TODO comment and lacks actual implementation, which could lead to navigation without proper verification UX Issue No way to resend verification code or go back to the previous step if user enters wrong code

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
Possible issue	Add null checks before accessing nested object properties to prevent runtime errors Add error handling for the case when verification code sending fails silently. Check if result and result.user exist before accessing them. crux-frontend/hooks/useAuth.ts [48-59] if (result?.userConfirmed === false) { + if (!result.user) { + setError('User object not found'); + resolve(false); + return; + } // Send verification code to user's email result.user.getAttributeVerificationCode('email', { onSuccess: () => { resolve(true); }, onFailure: (err) => { setError(err.message || 'Failed to send verification code'); resolve(false); }, }); } Apply this suggestion Suggestion importance[1-10]: 8 Why: The suggestion addresses a critical potential runtime error by adding null checks for the result.user object. This is important for preventing application crashes and improving error handling reliability.	8
	Add defensive checks for undefined or empty arrays to prevent null reference errors The email verification status check should handle the case where attributes is undefined or empty to prevent runtime errors. crux-frontend/hooks/useAuth.ts [92-101] -const emailVerified = attributes?.find( +if (!attributes || attributes.length === 0) { + setError('Could not retrieve user attributes'); + resolve(false); + return; +} +const emailVerified = attributes.find( (attr) => attr.getName() === 'email_verified' )?.getValue(); if (emailVerified === 'true') { resolve(true); } else { setError('Email not verified'); resolve(false); } Apply this suggestion Suggestion importance[1-10]: 8 Why: The suggestion adds crucial defensive programming checks to prevent potential runtime errors when handling user attributes, which is essential for application stability.	8
General	Validate user input before processing to prevent invalid submissions The verification code input should be validated before submitting to prevent unnecessary API calls with invalid codes. crux-frontend/app/index.tsx [21-28] const handleVerification = async () => { + if (!verificationCode || verificationCode.length < 6) { + setError('Please enter a valid verification code'); + return; + } // Add logic to verify the code // If successful, navigate to the next screen router.push({ pathname: '/verify/[phone]', params: {phone: identifier}, }); }; Apply this suggestion Suggestion importance[1-10]: 7 Why: The suggestion adds important input validation to prevent unnecessary API calls and improve user feedback, enhancing both user experience and application efficiency.	7

Explore these optional code suggestions:

Category	Suggestion	Score
Possible issue	Add null check for user object before attempting to send verification code Add error handling for the case when the verification code cannot be sent. Currently, the code silently fails if result or result.user is undefined. crux-frontend/hooks/useAuth.ts [48-59] if (result?.userConfirmed === false) { + if (!result.user) { + setError('User object is undefined'); + resolve(false); + return; + } // Send verification code to user's email result.user.getAttributeVerificationCode('email', { onSuccess: () => { resolve(true); }, onFailure: (err) => { setError(err.message || 'Failed to send verification code'); resolve(false); }, }); } Apply this suggestion Suggestion importance[1-10]: 8 Why: The suggestion addresses a critical potential runtime error by adding null checks for the user object, preventing possible application crashes when trying to access methods on undefined objects.	8
	Validate user input before processing verification code Add validation for the verification code input to ensure it's not empty before submitting. crux-frontend/app/index.tsx [21-28] const handleVerification = async () => { + if (!verificationCode.trim()) { + // You might want to use your error state management here + return; + } // Add logic to verify the code // If successful, navigate to the next screen router.push({ pathname: '/verify/[phone]', params: {phone: identifier}, }); }; Apply this suggestion Suggestion importance[1-10]: 7 Why: The suggestion adds important input validation to prevent processing empty verification codes, which could lead to unnecessary API calls or invalid state handling.	7
General	Properly manage loading state during asynchronous operations Add loading state handling during the email verification check to prevent potential race conditions. crux-frontend/hooks/useAuth.ts [86-94] +setLoading(true); cognitoUser.getUserAttributes((err, attributes) => { + setLoading(false); if (err) { setError(err.message || 'Failed to get user attributes'); resolve(false); return; } const emailVerified = attributes?.find( (attr) => attr.getName() === 'email_verified' )?.getValue(); Apply this suggestion Suggestion importance[1-10]: 6 Why: The suggestion improves user experience by properly managing loading states during async operations, preventing potential UI inconsistencies during attribute verification.	6
