Project Structure

A well-organized project structure is crucial for maintaining scalability and readability in React applications. As your project grows, a structured approach helps in managing components, utilities, and other code files efficiently. In this section, we will explore best practices for structuring a React 19 project.

Basic Example

Let’s consider a basic example of a project structure for a simple React application. This structure includes folders for components, utilities, and pages:

// src/components/Header.jsx
import React from 'react';
 
function Header() {
  return <h1>Welcome to my website</h1>;
}
 
export default Header;

In this example, we have a components folder where we store our reusable UI components. Each component is in its own file, making it easy to import and use throughout the application.

Advanced Usage

For larger applications, we might want to organize our components and utilities further. We can create subfolders for different types of components or utilities:

// src/components/layout/Header.jsx
import React from 'react';
 
function Header() {
  return <h1>Welcome to my website</h1>;
}
 
export default Header;

// src/components/features/TodoList.jsx
import React, { useState } from 'react';
 
function TodoList() {
  const [todos, setTodos] = useState([]);
 
  const handleAddTodo = () => {
    setTodos([...todos, 'New Todo']);
  };
 
  return (
    <div>
      <h2>Todo List</h2>
      <ul>
        {todos.map((todo, index) => (
          <li key={index}>{todo}</li>
        ))}
      </ul>
      <button onClick={handleAddTodo}>Add Todo</button>
    </div>
  );
}
 
export default TodoList;

In this advanced example, we have subfolders for layout and features components. This structure helps in keeping related components together and makes it easier to find a specific component.

Best Practices

Here are some best practices to keep in mind when structuring your React project:

• Keep your components small and focused on a single task.
• Use descriptive folder and file names to make it easy to find specific components or utilities.
• Avoid deeply nested folders and try to keep your structure as flat as possible.
• Use a consistent naming convention throughout your project.

Key Takeaways

• Keep your project structure organized and scalable.
• Use subfolders to group related components or utilities.
• Follow a consistent naming convention and use descriptive names for folders and files.
• Keep your components small and focused on a single task to make your code more maintainable and reusable.
