Project Structure for Shopping Cart Application

Welcome back to the third installment of our "Shopping Cart Application" series! In this part, we'll take a closer look at the heart of our application - the project structure. Proper organization ensures maintainability and ease of collaboration.

In this installment, we'll dive into the project structure, focusing on organizing components, containers, services, and utilities. Let's get started!

Project structure
Components: Building Blocks of UI
Containers: Managing State and Logic
Services: Interacting with External Resources
Utilities: Helper Functions and Utilities

2. Components: Building Blocks of UI

Components are the building blocks of our user interface (UI). They represent reusable parts of the UI, such as buttons, cards, or input fields.

/components/Footer.jsx

function Footer() {
  return (
    <h1 class="text-xl text-red-700 font-bold">
      Footer
    </h1>
  )
}

export default Footer

/components/Header.jsx

function Header() {
  return (
    <h1 class="text-xl text-red-700 font-bold">
      Header
    </h1>
  )
}

export default Header;

/components/Layout.jsx

import Header from "./Header";
import Footer from "./Footer";

function Layout() {
  return (
    <>
      <header>
      <hr class="my-2">
      Content
      <hr class="my-2">
      <footer>

  );
}

export default Layout;</footer></header>

3. Containers: Managing State and Logic

Containers are components responsible for managing state and logic. They often wrap presentational components and provide them with data and behavior. Here's an example of an api.js service:

/containers/Cart.jsx

function Cart() {
  return (
    <h1 class="text-2xl text-blue-700 font-bold">
      Cart Page!
    </h1>
  )
}

export default Cart

/containers/Home.jsx

function Home() {
  return (
    <h1 class="text-2xl text-blue-700 font-bold">
      Home Page!
    </h1>
  )
}

export default Home

/containers/Products.jsx

function Products() {
  return (
    <h1 class="text-2xl text-blue-700 font-bold">
      Products Page!
    </h1>
  )
}

export default Products

4. Services: Interacting with External Resources

Services handle interactions with external resources, such as APIs. They encapsulate logic related to fetching and sending data. Here's an example of an api.js service:

/services/api.js

// API Services

5. Utilities: Helper Functions and Utilities

Utilities contain helper functions and utility scripts used across the application. They aid in common tasks such as data manipulation or formatting. Here's an example of a helpers.js utility:

/utils/helpers.js

// Helpers utils

Conclusion

Organizing your shopping cart application into components, containers, services, and utilities helps maintain a clean and scalable codebase. By separating concerns, you can easily manage state, logic, and interactions with external resources. Happy coding!

"The key to writing maintainable code is to keep it organized and modular. Break it down into smaller pieces, and tackle one problem at a time!"
