Forms and Validation
Strengthening Dynamic Form Validation for Phone Data Integrity
Improved complex Angular Material profile forms by preventing duplicate phone records, tightening input validation, and making duplicate error states more reliable across dynamic form rows.
The Problem
Dynamic phone forms allowed duplicate phone numbers and duplicate phone types, making profile data integrity difficult to maintain.
Composite uniqueness across number, extension, and type was difficult to enforce consistently, while Angular Material error states did not always surface validation problems clearly. Invalid extension input and dynamic row edge cases reduced confidence in the editing experience.
Technical Leadership
- Designed validation logic around real user editing behavior instead of relying on late-stage backend rejection
- Implemented duplicate detection across phone number, extension, and phone type combinations
- Applied validation consistently across dynamic FormArray rows as entries were added, edited, and removed
- Improved Angular Material error-state behavior so duplicate and invalid input issues surfaced more reliably
- Balanced strict data integrity rules with practical usability in profile editing workflows
What I Did
Dynamic validation strategy built to protect data integrity across complex Angular Material form interactions.
Implemented composite duplicate detection, stronger extension validation, and more reliable inline error handling across dynamic form rows.
- Composite Uniqueness Enforcement: Built duplicate detection logic across phone number, extension, and phone type combinations.
- FormArray-Wide Validation: Applied validation across the full dynamic form structure instead of only the active row.
- Improved Error-State Handling: Strengthened Angular Material error display behavior so duplicate and invalid inputs surfaced clearly.
- Extension Hardening: Enforced numeric-only entry and maximum-length validation for extension values.
- Dynamic State Cleanup: Ensured duplicate states cleared correctly when users edited or removed conflicting entries.
Testing and Validation
Validated correctness through unit testing focused on dynamic form behavior, duplicate clearing, and template error-state reliability.
- Added Karma unit tests for duplicate detection across dynamic form entries
- Verified add, edit, and remove scenarios to ensure duplicate states cleared correctly
- Covered composite uniqueness rules across number, extension, and type
- Confirmed template error states surfaced reliably when validation rules were triggered
Outcome
- Reduced duplicate phone data entering user profiles
- Improved real-time validation feedback in Angular Material forms
- Increased confidence in dynamic profile editing workflows
- Delivered a cleaner and more reliable validation experience
- Strengthened frontend data integrity before submission
