Technical Challenges and Solutions
Excessive Zustand Over-rendering Issue
Problem
Zustand was used to instantly reflect user input on the final invitation, but unnecessary re-rendering occurred with every input change, leading to performance degradation and screen flickering.
Solution
Optimized Zustand Store using `useCallback` internally and introduced debouncing to trigger rendering after a certain delay following input. This significantly reduced the number of renders.
Excessive Data Transmission on POST Requests
Problem
When creating invitations, all values were sent at once, making error tracking and debugging difficult, and requests were sent without proper validation.
Solution
Improved the process by dividing the creation into stages, sending only necessary data incrementally. This allowed for error checking at specific stages, reducing debugging time and better suiting the user flow.
