What is new in Astro 3?

We have very interesting feature in Astro's new version which is:

Astro View Transitions:

Embrace the future of web design with View Transitions, a groundbreaking set of platform APIs that empower your web applications with captivating native browser transition effects between pages. Until now, this level of seamless interaction was exclusive to Single Page Applications (SPAs). However, the collaborative efforts of web browsers and visionary specification authors have paved the way for these native page transitions to flourish across the entire web platform. With the launch of Astro 3.0, that becomes very easy with new Astro View Transitions

Installing Astro 3

To get started with Astro 3, you need to install it globally on your system. Open your terminal and run the following command:

bash
npm install -g astro

Creating a New Astro 3 Project

Astro 3 makes project creation a breeze. To initiate a new Astro project, simply use the following command:

bash
npx create-astro@latest my-astro-project

This command sets up a new Astro project named "my-astro-project." You can replace this with your desired project name.

Running the Development Server

Once your project is set up, navigate to the project directory using the cd command and launch the development server:

bash
cd my-astro-project
npm run dev

Astro will start a local development server, and you can access your project at http://localhost:3000.

Creating Pages in Astro 3

Astro 3 adopts a component-driven approach. To create a new page, you'll need to add a .astro file in the src/pages directory. For example, to create an "about" page, run:

bash
touch src/pages/about.astro

Now, let's create a simple "about" page in src/pages/about.astro:

about.astro
---
import { meta } from "@astro/types";
const { title, description } : meta;
---
 
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>{title}</title>
    <meta name="description" content="{description}">
</head>
<body>
    <h1>About Us</h1>
    <p>Welcome to our Astro 3-powered website!</p>
</body>
</html>
