Let's take some time to investigate the project.

• app: This directory is the heart of your application, housing all the routes, components, and logic. It's where you'll spend most of your time building your application's core functionality;
• app/lib: It contains essential functions used throughout your application. These functions serve various purposes, including utility functions that can be reused across different parts of your project and data fetching functions responsible for retrieving data;
• app/ui: Here, you'll find all the UI components that make up the visual elements of your application, such as cards, tables, and forms. These components have been pre-styled to save time;
• public: It stores static assets like images used in your application;
• scripts: A seeding script in this directory will be useful for populating the database in a later chapter. This folder is not a natural Next.js feature but has been created specifically to work with the real database.
