Getting Started with Astro 5

Astro 5¹ brings significant improvements to the already powerful web framework. In this guide, we’ll explore the key features and how to get started building your first Astro site.

What is Astro?

Astro is an all-in-one web framework designed for building fast, content-focused websites. It uses an islands architecture approach, shipping zero JavaScript by default and only hydrating interactive components when needed.

Key Features

Zero JS by default — Astro renders your pages to static HTML
Islands architecture — Interactive components load only when needed
UI-agnostic — Use React, Vue, Svelte, or any framework
Content collections — Type-safe content management with Zod schemas

Getting Started

To create a new Astro project:

npm create astro@latest

Then navigate to your project and start the dev server:

cd my-astro-site
npm run dev

Content Collections

Astro’s content collections provide type-safe content management:

import { defineCollection } from 'astro:content'
import { glob } from 'astro/loaders'
import { z } from 'astro/zod'

const blog = defineCollection({
 loader: glob({ pattern: '**/*.md', base: './src/content/blog' }),
 schema: z.object({
 title: z.string(),
 pubDate: z.coerce.date(),
 }),
})

export const collections = { blog }

This ensures your content is validated at build time, preventing errors before they reach production.

Astro 5 makes it easier than ever to build performant websites. Start exploring and see what you can build!
