In this post, we will explore how to set up a clear and organized folder structure for an enrollment system using the MVC (Model-View-Controller) pattern in simple JavaScript. By keeping the code well-structured, you can manage students, courses, and enrollments efficiently. This approach helps you keep your code easy to maintain and expand as needed. Let’s break down the main folders and files to see how the project is organized!

Explanation of Key Folders and Files:

• /config: Stores configuration files, such as database or environment configurations.

• /controllers: Contains business logic and processes user requests and interactions.

• /models: Manages data and business rules. These files handle interactions with the database or APIs.

• /components: Contains HTML templates and JavaScript to render the user interface for various sections of the app (e.g., students, courses, enrollments).

• /public: Static assets like CSS, JavaScript, and images.

• /routes: Defines routes/endpoints for the app. Routes map URLs to controller functions.

• /utils: Contains utility functions such as form validation, date manipulation, etc.

• /services: Handles API communications or external service calls.

• /tests: Contains test files for unit and integration testing to ensure code functionality.

Summary:

This folder structure provides:

Modularity: Each feature (e.g., students, courses, enrollments) has its own MVC components.

Scalability: You can easily expand the project by adding new features without major refactoring. Separation of Concerns: Business logic, UI, and data handling are all neatly separated. This setup will help ensure maintainable and scalable code for your enrollment system using vanilla JavaScript with the MVC pattern.
