Summary of Work

Overview

This pull request implements a comprehensive email validation system for the JobIt application, addressing multiple aspects of email format validation, unique constraints, and data integrity.

Key Changes

1. Email Validation Implementation

• Created lib/validation.ts with robust email validation logic
• Implemented RFC 5322 standard email format validation regex
• Added comprehensive email normalization functionality

Validation Features:

• Strict email format checking
• Length validation (5-320 characters)
• Case-insensitive normalization
• Comprehensive regex validation

2. Database-Level Unique Constraint

• Updated models/User.ts with unique email constraint
• Implemented case-insensitive email uniqueness
• Added pre-save middleware for email normalization

Unique Constraint Features:

• MongoDB unique index with case-insensitive collation
• Prevents duplicate email registrations
• Normalizes emails before storage

3. Utility Functions

• Added normalizeEmail() function in lib/validation.ts
• Created isValidEmail() and validateEmailWithDetails() in lib/utils.ts
• Implemented static method isEmailTaken() in User model

Acceptance Criteria Met

• ✅ Implemented RFC 5322 standard email format validation
• ✅ Prevented registration with invalid email formats
• ✅ Added database-level unique constraint on email field
• ✅ Implemented case-insensitive email uniqueness check
• ✅ Created comprehensive test suite with 10+ email format scenarios

Testing Approach

• Developed extensive test cases in __tests__/email-validation.test.ts
• Covered various email format scenarios (valid and invalid)
• Tested normalization and uniqueness constraints
• Verified case-insensitive email handling

Potential Future Improvements

• Implement email verification mechanism
• Add more specific domain validation
• Enhance error handling for edge cases

Testing Instructions

1. Ensure MongoDB is running
2. Set appropriate environment variables
3. Run test suite to verify implementation

Breaking Changes

• None. Extends existing validation with additional robust checks

Related Issues
