Building a Modern Web Application with Astro

Astro is a modern web framework that delivers lightning-fast performance by shipping zero JavaScript by default.

Why Astro?

In the ever-evolving landscape of web development, choosing the right framework can make or break your project. Astro stands out for several compelling reasons:

Performance First — Ship less JavaScript, load faster
Content Focused — Perfect for blogs, documentation, and marketing sites
Flexible — Use any UI framework (React, Vue, Svelte, etc.)
Island Architecture — Hydrate only interactive components

The best code is no code at all. Astro embraces this philosophy by minimizing client-side JavaScript.

Getting Started

First, create a new Astro project:

npm create astro@latest my-project
cd my-project
npm install
npm run dev

Project Structure

A typical Astro project looks like this:

├── public/
│   └── favicon.svg
├── src/
│   ├── components/
│   │   └── Header.astro
│   ├── layouts/
│   │   └── BaseLayout.astro
│   ├── pages/
│   │   └── index.astro
│   └── styles/
│       └── global.css
├── astro.config.mjs
└── package.json

Creating Components

Astro components use a .astro extension and support a powerful templating syntax:

---
// Component Script (runs at build time)
const { title, description } = Astro.props;
const publishDate = new Date().toLocaleDateString();
---

<article class="card">
  <h2>{title}</h2>
  <p>{description}</p>
  <time>{publishDate}</time>
</article>

<style>
  .card {
    padding: 1.5rem;
    border-radius: 8px;
    background: #f5f5f4;
  }
</style>

Key Features

Content Collections

Astro 2.0 introduced Content Collections for type-safe content management:

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

const posts = defineCollection({
  schema: z.object({
    title: z.string(),
    date: z.date(),
    tags: z.array(z.string()).optional(),
  }),
});

export const collections = { posts };

View Transitions

Astro 3.0 brought native view transitions:

---
import { ViewTransitions } from 'astro:transitions';
---
<head>
  <ViewTransitions />
</head>

Deployment

Deploy to any static hosting platform:

Vercel: npm run build && vercel deploy
Netlify: Connect your Git repository
GitHub Pages: Use the @astrojs/github-action
