Setting Up Your Development Environment

To get started with Astro.js, you’ll need Node.js installed on your computer. If you haven’t already, download and install Node.js (version 14.15.0 or higher) from nodejs.org.

Once Node.js is installed, open your terminal and run the following command to create a new Astro project:

npm create astro@latest

Follow the prompts in your terminal to customize your new project.

Launching Your Development Server

Navigate into your new project directory and start the development server:

cd my-astro-project
npm install
npm start

This command will compile your project and serve it on a local development server, usually at http://localhost:4321. You can view your site by opening this URL in a web browser.

Building Your First Page

Astro uses a file-based routing system. To create a new page, simply add a .astro file in the src/pages/ directory. Here’s a quick example:

src/pages/index.astro

---
// Frontmatter script space
---

<html>
  <head>
    <title>My Astro Website</title>
  </head>
  <body>
    <h1>Hello, Astro!</h1>
  </body>
</html>

This code defines a basic HTML structure for your home page with a greeting message.

Adding Components

Astro allows you to integrate components from other frameworks like React or Vue easily. For example, to use React components, first install the necessary dependencies:

npx astro add react

Then, you can import React components into your .astro files and use them alongside traditional HTML elements.

Example:

---
import MyReactComponent from '../components/MyReactComponent.jsx';
---

<div>
  <MyReactComponent />
</div>

Styling Your Site

Astro supports various styling options, including Tailwind CSS, which can be easily integrated into your project for rapid styling development.

To add Tailwind CSS, first install the necessary dependencies:

npx astro add tailwind

Then follow the setup instructions in the Astro documentation to configure Tailwind CSS for your project.
