Using Integrations

Astro Integrations add new functionality and behaviors for your project with only a few lines of code. You can write a custom integration yourself, use an official integration, or use integrations built by the community.

Integrations can…

  • Unlock React, Vue, Svelte, Solid, and other popular UI frameworks.
  • Integrate tools like Tailwind, and Partytown with a few lines of code.
  • Add new features to your project, like automatic sitemap generation.
  • Write custom code that hooks into the build process, dev server, and more.

UI Frameworks

SSR Adapters

Others

Astro includes an astro add command to automate the setup of integrations.

Run astro add [integration-name] and our automatic integration wizard will update your configuration file and install any necessary dependencies.

npx astro add react

It’s even possible to configure multiple integrations at the same time!

npx astro add react tailwind partytown

Astro integrations are always added through the integrations property in your astro.config.mjs file.

There are three common ways to import an integration into your Astro project:

  1. Installing an npm package integration.
  2. Import your own integration from a local file inside your project.
  3. Write your integration inline, directly in your config file.
astro.config.mjs
import {defineConfig} from 'astro/config';
import installedIntegration from '@astrojs/vue';
import localIntegration from './my-integration.js';

export default defineConfig({
  integrations: [
    // 1. Imported from an installed npm package
    installedIntegration(),
    // 2. Imported from a local JS file
    localIntegration(),
    // 3. An inline object
    {name: 'namespace:id', hooks: { /* ... */ }},
  ]
})

Check out the Integration API reference to learn all of the different ways that you can write an integration.

Integrations are almost always authored as factory functions that return the actual integration object. This lets you pass arguments and options to the factory function that customize the integration for your project.

integrations: [
  // Example: Customize your integration with function arguments
  sitemap({filter: true})
]

Falsy integrations are ignored, so you can toggle integrations on & off without worrying about left-behind undefined and boolean values.

integrations: [
  // Example: Skip building a sitemap on Windows
  process.platform !== 'win32' && sitemap()
]

You can find many integrations developed by the community in the Astro Integrations Directory. Follow links there for detailed usage and configuration instructions.

Astro’s Integration API is inspired by Rollup and Vite, and designed to feel familiar to anyone who has ever written a Rollup or Vite plugin before.
