Streamlining Astro Development with Claude Code: Content Site Guide

Accelerating Astro Development with Claude Code

Astro is a framework that has drawn attention for its “island architecture” performance and its content-first design. With Claude Code, you can smoothly navigate Astro’s unique syntax and content collection design.

Project Setup

> Create an Astro project.
> Requirements:
> - TypeScript strict
> - Tailwind CSS
> - MDX support
> - Automatic sitemap generation

Claude Code will present the astro.config.mjs configuration as well as the commands to install the required integrations.

// astro.config.mjs
import { defineConfig } from 'astro/config';
import tailwind from '@astrojs/tailwind';
import mdx from '@astrojs/mdx';
import sitemap from '@astrojs/sitemap';

export default defineConfig({
  site: 'https://example.com',
  integrations: [tailwind(), mdx(), sitemap()],
  markdown: {
    shikiConfig: {
      theme: 'github-dark',
    },
  },
});

Designing Content Collections

Schema Definition

> Create a content collection schema for blog posts.
> Include title, description, pubDate, tags, draft, and coverImage.

// src/content/config.ts
import { defineCollection, z } from 'astro:content';

const blog = defineCollection({
  type: 'content',
  schema: z.object({
    title: z.string().max(100),
    description: z.string().max(200),
    pubDate: z.coerce.date(),
    tags: z.array(z.string()).default([]),
    draft: z.boolean().default(false),
    coverImage: z.string().optional(),
  }),
});

export const collections = { blog };

Using Island Architecture

Astro’s biggest feature, island architecture, only ships JavaScript for the interactive components.

---
// Static parts are rendered on the server
import Header from '../components/Header.astro';
import SearchBar from '../components/SearchBar.tsx';
import Footer from '../components/Footer.astro';
---

<Header />
<!-- client:visible only hydrates when it enters the viewport -->
<SearchBar client:visible />
<Footer />

If you ask Claude Code, “Should this component use client:load or client:visible?”, it will recommend the optimal directive for your use case.

Dynamic Routing and Page Generation

> Dynamically generate per-tag article listing pages.
> Include pagination.

---
// src/pages/tag/[tag]/[...page].astro
import { getCollection } from 'astro:content';
export async function getStaticPaths({ paginate }) {
  const posts = await getCollection('blog', ({ data }) => !data.draft);
  const tags = [...new Set(posts.flatMap(post => post.data.tags))];

  return tags.flatMap(tag => {
    const filtered = posts.filter(post => post.data.tags.includes(tag));
    return paginate(filtered, { params: { tag }, pageSize: 10 });
  });
}
const { page } = Astro.props;
---

Performance Optimization

Astro is fast by default, but you can go further with image optimization and prefetch settings. Tell Claude Code “I want a Lighthouse score of 100” and it will suggest concrete optimization opportunities.

Summary

With Claude Code, you can quickly get the hang of Astro’s unique syntax and content-collection design to build high-performance sites. See also the SSR/SSG comparison guide and SEO optimization.
