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.
