## Installation
|
|
|
|
### Quick Install
|
|
|
|
The `astro add` command-line tool automates the installation for you. Run one of the following commands in a new terminal window. (If you aren't sure which package manager you're using, run the first command.) Then, follow the prompts, and type "y" in the terminal (meaning "yes") for each one.
|
|
|
|
```sh
|
|
# Using NPM
|
|
npm run astro add alpinejs
|
|
# Using Yarn
|
|
yarn astro add alpinejs
|
|
# Using PNPM
|
|
pnpm astro add alpinejs
|
|
```
|
|
|
|
Finally, in the terminal window running Astro, press `CTRL+C` and then type `npm run astro dev` to restart the dev server.
|
|
|
|
### Manual Install
|
|
|
|
First, install the `@astrojs/alpinejs` package using your package manager. If you're using npm or aren't sure, run this in the terminal:
|
|
|
|
```sh
|
|
npm install @astrojs/alpinejs
|
|
```
|
|
|
|
Most package managers will install associated peer dependencies as well. However, if you see a "Cannot find package 'alpinejs'" (or similar) warning when you start up Astro, you'll need to manually install Alpine.js yourself:
|
|
|
|
```sh
|
|
npm install alpinejs @types/alpinejs
|
|
```
|
|
|
|
Then, apply this integration to your `astro.config.*` file using the `integrations` property:
|
|
|
|
|
|
```js title="astro.config.mjs" ins={2} "alpine()"
|
|
import { defineConfig } from 'astro/config';
|
|
import alpine from '@astrojs/alpinejs';
|
|
|
|
export default defineConfig({
|
|
// ...
|
|
integrations: [alpine()],
|
|
});
|
|
```
|
|
|
|
Finally, restart the dev server.
|
|
|
|
## Usage
|
|
|
|
Once the integration is installed, you can use [Alpine.js](https://alpinejs.dev/) directives and syntax inside any Astro component. The Alpine.js script is automatically added and enabled on every page of your website.
|
|
|
|
Check our [Astro Integration Documentation][astro-integration] for more on integrations.
|
|
|
|
## Limitations
|
|
|
|
The Apline.js integration does not give you control over how the script is loaded or initialized. If you require this control, consider [installing and using Alpine.js manually](https://alpinejs.dev/essentials/installation). Astro supports all officially documented Alpine.js manual setup instructions, using `<script>` tags inside of an Astro component.
|
|
|
|
**It is not currently possible to [extend Alpine.js](https://alpinejs.dev/advanced/extending) when using this component.** If you need this feature, consider following [the manual Alpine.js setup](https://alpinejs.dev/essentials/installation) instead using an Astro script tag:
|
|
|
|
```astro title="src/pages/index.astro"
|
|
<!-- Example: Load AlpineJS on a single page. -->
|
|
<script>
|
|
import Alpine from 'alpinejs';
|
|
|
|
// Optional: Extend Alpine.js
|
|
// Alpine.directive('foo', ...)
|
|
|
|
window.Alpine = Alpine;
|
|
Alpine.start();
|
|
</script>
|
|
```
|
|
|
|
## Configuration
|
|
|
|
The Apline.js integration does not support any custom configuration at this time.
|
|
|
|
## Examples
|
|
|
|
- The [Astro Alpine.js example](https://github.com/withastro/astro/tree/latest/examples/framework-alpine) shows how to use Alpine.js in an Astro project.
