# @astrojs/svelte 🧡
|
|
|
|
This **[Astro integration][astro-integration]** enables server-side rendering and client-side hydration for your [Svelte](https://svelte.dev/) components.
|
|
|
|
## Installation
|
|
|
|
There are two ways to add integrations to your project. Let's try the most convenient option first!
|
|
|
|
### `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:
|
|
|
|
```sh
|
|
# Using NPM
|
|
npx astro add svelte
|
|
# Using Yarn
|
|
yarn astro add svelte
|
|
# Using PNPM
|
|
pnpm astro add svelte
|
|
```
|
|
|
|
If you run into any issues, [feel free to report them to us on GitHub](https://github.com/withastro/astro/issues) and try the manual installation steps below.
|
|
|
|
### Install dependencies manually
|
|
|
|
First, install the `@astrojs/svelte` integration like so:
|
|
|
|
```sh
|
|
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:
|
|
|
|
```sh
|
|
npm install svelte
|
|
```
|
|
|
|
Now, apply this integration to your `astro.config.*` file using the `integrations` property:
|
|
|
|
__`astro.config.mjs`__
|
|
|
|
```js ins={2} "svelte()"
|
|
import { defineConfig } from 'astro/config';
|
|
import svelte from '@astrojs/svelte';
|
|
|
|
export default defineConfig({
|
|
// ...
|
|
integrations: [svelte()],
|
|
});
|
|
```
|
|
|
|
## Getting started
|
|
|
|
To use your first Svelte component in Astro, head to our [UI framework documentation][astro-ui-frameworks]. You'll explore:
|
|
- 📦 how framework components are loaded,
|
|
- 💧 client-side hydration options, and
|
|
- 🤝 opportunities to mix and nest frameworks together
|
|
|
|
## Troubleshooting

## Options
|
|
|
|
This integration is powered by `@sveltejs/vite-plugin-svelte`. To customize the Svelte compiler, options can be provided to the integration. See the [`@sveltejs/vite-plugin-svelte` docs](https://github.com/sveltejs/vite-plugin-svelte/blob/HEAD/docs/config.md) for more details.
|
|
|
|
### Default options
|
|
|
|
This integration passes the following default options to the Svelte compiler:
|
|
|
|
```js
|
|
const defaultOptions = {
|
|
emitCss: true,
|
|
compilerOptions: { dev: isDev, hydratable: true },
|
|
preprocess: vitePreprocess()
|
|
};
|
|
```
|
|
|
|
These `emitCss`, `compilerOptions.dev`, and `compilerOptions.hydratable` values are required to build properly for Astro and cannot be overridden.
|
|
|
|
Providing your own `preprocess` options **will** override the [`vitePreprocess()`](https://github.com/sveltejs/vite-plugin-svelte/blob/HEAD/docs/preprocess.md) default. Make sure to enable the preprocessor flags needed for your project.
|
|
|
|
You can set options either by passing them to the `svelte` integration in `astro.config.mjs` or in `svelte.config.js`. Either of these would override the default `preprocess` setting:
|
|
|
|
__`astro.config.mjs`__
|
|
|
|
```js
|
|
import { defineConfig } from 'astro/config';
|
|
import svelte from '@astrojs/svelte';
|
|
|
|
export default defineConfig({
|
|
integrations: [svelte({ preprocess: [] })],
|
|
});
|
|
```
|
|
|
|
__`svelte.config.js`__
|
|
|
|
```js
|
|
export default {
|
|
preprocess: [],
|
|
};
|
|
```
|
|
|
|
## Intellisense for TypeScript
|
|
|
|
**Added in:** `@astrojs/svelte@2.0.0`
|
|
|
|
If you're using a preprocessor like TypeScript or SCSS in your Svelte files, you can create a `svelte.config.js` file so that the Svelte IDE extension can correctly parse the Svelte files.
|
|
|
|
__`svelte.config.js`__
|
|
|
|
```js
|
|
import { vitePreprocess } from '@astrojs/svelte';
|
|
|
|
export default {
|
|
preprocess: vitePreprocess(),
|
|
};
|
|
```
|
|
|
|
This config file will be automatically added for you when you run `astro add svelte`.
