@astrojs/svelte

@astrojs/svelte 🧡

This Astro integration enables server-side rendering and client-side hydration for your Svelte components.

Installation

There are two ways to add integrations to your project. Let's try the most convenient option first!

(experimental) astro add command

Astro includes a CLI tool for adding first party integrations: astro add. This command will:

1. (Optionally) Install all necessary dependencies and peer dependencies
2. (Also optionally) Update your astro.config.* file to apply this integration

To install @astrojs/svelte, run the following from your project directory and follow the prompts:

# Using NPM
npx astro add svelte
# Using Yarn
yarn astro add svelte
# Using PNPM
pnpx astro add svelte

If you run into any hiccups, feel free to log an issue on our GitHub and try the manual installation steps below.

Install dependencies manually

First, install the @astrojs/svelte integration like so:

npm install @astrojs/svelte

Most package managers will install associated peer dependencies as well. Still, if you see a "Cannot find package 'svelte'" (or similar) warning when you start up Astro, you'll need to install Svelte:

npm install svelte

Now, apply this integration to your astro.config.* file using the integrations property:

astro.config.mjs

import svelte from '@astrojs/svelte';

export default {
  // ...
  integrations: [svelte()],
}

Getting started

To use your first Svelte component in Astro, head to our UI framework documentation. You'll explore:

• 📦 how framework components are loaded,
• 💧 client-side hydration options, and
• 🪆 opportunities to mix and nest frameworks together
