1. Learning Backend and TypeScript:

  • Challenge: During the initial stages, the challenge involved simultaneously learning backend development and TypeScript. This was particularly demanding given the multifaceted role encompassing UI/UX design, frontend and backend development, and deployment.
  • Resolution: Overcame the challenge by diligently following the "Pro Backend" course by Hitesh Choudhary. Seeking guidance from creators of libraries such as Zod and Pino validated the implementation of best practices in TypeScript.

2. Centralized Error Handling:

  • Challenge: Distinguishing catastrophic errors from operational errors and handling them centrally proved to be a significant challenge. The decision to encapsulate error-handling logic in a dedicated and centralized object required meticulous consideration.
  • Resolution: Successfully implemented a centralized error-handling system to categorize and manage errors efficiently. This involved encapsulating error-handling logic, ensuring proper logging, deciding error-crashing strategies, and monitoring metrics.

3. Adopting New Technologies:

  • Challenge: The decision to adopt new technologies, such as Next.js 13 and React Query and more, introduced a learning curve. Adapting to the changes and incorporating the latest features while maintaining a high level of performance required a thoughtful approach.
  • Resolution: Successfully navigated the challenge by investing time in understanding the intricacies of Next.js 13, React Query and Shadcn/UI. The adoption of these technologies contributed to the enhancement of the application's frontend.

4. UI/UX Design:

  • Challenge: As a developer and not a dedicated UI/UX designer, perfecting the UI for optimal user experience presented a substantial challenge. Achieving a balance between aesthetics, accessibility, and responsiveness demanded extensive effort.
  • Resolution: Despite the challenge, dedicated significant time to refining the UI, ensuring it aligns with modern design principles. The resulting UI not only met high standards but also contributed to an engaging and visually appealing user interface.
