👩‍🚀 Astro

A next-generation static-site generator with partial hydration. Use your favorite JS framework and ship bare-minimum JS (or none at all!).

🔧 Setup

npm install astro

TODO: astro boilerplate

🧞 Development

Add a dev npm script to your /package.json file:

{
  "scripts": {
    "dev": "astro dev ."
  }
}

Then run:

npm run dev

⚙️ Configuration

To configure Astro, add a astro.config.mjs file in the root of your project. All of the options can be omitted. Here are the defaults:

export default {
  /** Where to resolve all URLs relative to. Useful if you have a monorepo project. */
  projectRoot: '.',
  /** Path to Astro components, pages, and data */
  astroRoot: './astro',
  /** When running `astro build`, path to final static output */
  dist: './_site',
  /** A folder of static files Astro will copy to the root. Useful for favicons, images, and other files that don‘t need processing. */
  public: './public',
  /** Extension-specific handlings */
  extensions: {
    /** Set this to "preact" or "react" to determine what *.jsx files should load */
    '.jsx': 'react',
  },
};

💧 Partial Hydration

By default, Astro outputs zero client-side JS. If you'd like to include an interactive component in the client output, you may use any of the following techniques.

• MyComponent:load will render MyComponent on page load
• MyComponent:idle will use requestIdleCallback to render MyComponent as soon as main thread is free
• MyComponent:visible will use an IntersectionObserver to render MyComponent when the element enters the viewport

💅 Styling

If you‘ve used Svelte’s styles before, Astro works almost the same way. In any .astro file, start writing styles in a <style> tag like so:

<style>
.scoped {
  font-weight: bold;
}
</style>

<div class="scoped">I’m a scoped style</div>

👓 Sass

Astro also supports Sass out-of-the-box; no configuration needed:

<style lang="scss">
@use "../tokens" as *;

.title {
  color: $color.gray;
}
</style>

<h1 class="title">Title</h1>

Supports:

• lang="scss": load as the .scss extension
• lang="sass": load as the .sass extension (no brackets; indent-style)

🦊 Autoprefixer

We also automatically add browser prefixes using Autoprefixer. By default, Astro loads the default values, but you may also specify your own by placing a Browserslist file in your project root.

🍃 Tailwind

Astro can be configured to use Tailwind easily! Install the dependencies:

npm install @tailwindcss/jit tailwindcss

And also create a tailwind.config.js in your project root:

module.exports = {
  // your options here
}

Note: a Tailwind config file is currently required to enable Tailwind in Astro, even if you use the default options.

Then write Tailwind in your project just like you‘re used to:

<style>
@tailwind base;
@tailwind components;
@tailwind utilities;
</style>

🚀 Build & Deployment

Add a build npm script to your /package.json file:

{
  "scripts": {
    "dev": "astro dev .",
    "build": "astro build ."
  }
}

Then run:

npm run build

Now upload the contents of /_site_ to your favorite static site host.
