Preact Architecture

1. Introduction

Preact is a fast, lightweight alternative to React, designed for high performance in web applications. Its architecture is inspired by the principles of React, making it familiar for developers who have experience with the React ecosystem.

2. Key Concepts

3. Architecture Overview

The architecture of Preact is simple yet powerful, focusing on a minimal API while maintaining compatibility with React's ecosystem.

3.1 Component Structure

Components can be defined as classes or functions:

const MyComponent = () => {
    return 
Hello, Preact!
;
};
                

3.2 State Management

State can be managed using hooks:

import { useState } from 'preact/hooks';

const Counter = () => {
    const [count, setCount] = useState(0);
    return (
        

            
Count: {count}
             setCount(count + 1)}>Increment
        
    );
};
                

3.3 Lifecycle Methods

Preact provides lifecycle methods similar to React, allowing you to execute code at specific points in a component's life:

class MyComponent extends Component {
    componentDidMount() {
        console.log('Component mounted!');
    }

    render() {
        return 
Hello, World!
;
    }
}
                

4. Best Practices

Adopting best practices can enhance the maintainability and performance of your Preact applications:

• Use functional components and hooks for better performance and readability.
• Optimize rendering with memoization techniques provided by Preact.
• Keep components small and focused on a single responsibility.
• Utilize Preact's compatibility layer to easily integrate with existing React libraries.
