Astro is a modern static site generator that enables developers to build faster websites with a focus on performance. It allows you to use your favorite UI components from frameworks like React, Vue, and Svelte while optimizing your output for the best performance.

To get started with Astro, you need to have Node.js (version 14.0 or later) installed on your machine. Once you have Node.js, you can install Astro using npm or yarn:

npm create astro@latest

or

yarn create astro

After installing Astro, follow these steps to create a new project:

1. Open your terminal and navigate to the directory where you want to create your project.
2. Run the Astro create command:

Astro uses components to build your UI. You can create components using various frameworks or plain HTML. Here's a simple example of an Astro component:

---
// src/components/MyComponent.astro
---
Hello from MyComponent!
This is an Astro component.

To use this component in your page, you can import and include it:

---
// src/pages/index.astro
import MyComponent from '../components/MyComponent.astro';
---

Following best practices can enhance your Astro development experience:

• Keep components reusable and focused on a single task.
• Utilize Astro's image optimization features for better performance.
• Leverage partial hydration to load only the necessary JS.
