12.2. Render Props

Introduction Now, we’ll dive into Render Props in React, an advanced concept that helps you share code between components. Geek and Gal are here to make this topic fun and engaging, ensuring it’s easy to grasp for everyone, from beginners to experts!

Ready to learn about Render Props?

Absolutely! What are Render Props in React?

Render Props is a technique where a component's prop is assigned a function that returns a React element. This allows you to share code between components, making your code more reusable! 🎉

Sounds interesting! How do we use Render Props?

First, you create a component that accepts a prop which takes a function. This function will be responsible for rendering the actual content. Check out this example to get a better understanding:

class MouseTracker extends React.Component {
  constructor(props) {
    super(props);
    this.state = { x: 0, y: 0 };
  }

  handleMouseMove = (event) => {
    this.setState({ x: event.clientX, y: event.clientY });
  };

  render() {
    return (
      <div style={{ height: '100%' }} onMouseMove={this.handleMouseMove}>
        {this.props.render(this.state)}
      </div>
    );
  }
}

I see! So we create a component that accepts a prop, which is a function responsible for rendering the content. But how do we use this MouseTracker component?

Great question! You can use the MouseTracker component like this:

<MouseTracker
  render={(mouse) => (
    <p>
      The mouse is at ({mouse.x}, {mouse.y})
    </p>
  )}
/>

Got it! So we pass a function to the render prop, which is responsible for rendering the content!

Exactly! By using Render Props, you can share code and logic between components, making your code more modular and reusable! 🚀

Conclusion Render Props in React provide an effective way to share code between components, helping you create modular and reusable code. With this technique, you’ll be able to create more maintainable and scalable applications! 😄
