In this episode, we focus on simplifying our code while tackling technical debt, creating a new page for book entries, implementing route protection, and designing a book creation form. We also explore the ShadCN UI library for better component design and discuss the importance of clean code and user-friendly interfaces.

Key topics covered:

• Understanding and managing technical debt
• Creating and protecting routes in Next.js
• Designing a book creation form
• Using ShadCN to improve UI components
• Handling server actions and form validation
• Importance of collaboration in software development

Tackling Technical Debt and Keeping Code Simple Link to this headline

One of the biggest lessons from this episode is how complexity can creep into development. We discuss how the computer doesn’t always make things easier—sometimes, simpler solutions work better. Keeping things clean and manageable is key for long-term maintainability.

Creating a New Page for Book Entries Link to this headline

Adding new books to our virtual bookshelf requires a dedicated page. Thanks to Next.js’s folder-based routing, this is a straightforward process. However, we also discuss the importance of structuring the project efficiently to avoid unnecessary complications down the road.

Implementing Route Protection for Better Security Link to this headline

A crucial part of web development is ensuring only authorized users can access specific pages. We implement route protection to manage user authentication, securing our book creation feature from unauthorized access.

Designing a User-Friendly Book Creation Form Link to this headline

To allow users to add books seamlessly, we build a well-structured form. While HTML forms are powerful on their own, we explore ways to enhance them further using additional tools and validation methods.

Enhancing UI with ShadCN Components Link to this headline

We introduce ShadCN, a UI component library that simplifies styling and enhances user experience. By leveraging these components, we make our book form look and function better without adding unnecessary complexity.

Handling Server Actions and Form Validation Link to this headline

Server actions in Next.js streamline form submissions and data handling. We explore how to manage form inputs effectively and validate data using Zod, a powerful validation library that keeps our input clean and secure.
