# @astrojs/solid-js 💙
This **[Astro integration][astro-integration]** enables server-side rendering and client-side hydration for your [SolidJS](https://www.solidjs.com/) 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/solid-js`, run the following from your project directory and follow the prompts:
```sh
# Using NPM
npx astro add solid
# Using Yarn
yarn astro add solid
# Using PNPM
pnpm astro add solid
```
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/solid-js` integration like so:
```sh
npm install @astrojs/solid-js
```
Most package managers will install associated peer dependencies as well. Still, if you see a "Cannot find package 'solid-js'" (or similar) warning when you start up Astro, you'll need to install SolidJS:
```sh
npm install solid-js
```
Now, apply this integration to your `astro.config.*` file using the `integrations` property:
```diff lang="js" "solid()"
// astro.config.mjs
import { defineConfig } from 'astro/config';
+ import solid from '@astrojs/solid-js';
export default defineConfig({
// ...
integrations: [solid()],
// ^^^^^^^
});
```
## Getting started
To use your first SolidJS 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
## Options
### Combining multiple JSX frameworks
When you are using multiple JSX frameworks (React, Preact, Solid) in the same project, Astro needs to determine which JSX framework-specific transformations should be used for each of your components. If you have only added one JSX framework integration to your project, no extra configuration is needed.
Use the `include` (required) and `exclude` (optional) configuration options to specify which files belong to which framework. Provide an array of files and/or folders to `include` for each framework you are using. Wildcards may be used to include multiple file paths.
We recommend placing common framework components in the same folder (e.g. `/components/react/` and `/components/solid/`) to make specifying your includes easier, but this is not required:
```js
// astro.config.mjs
import { defineConfig } from 'astro/config';
import preact from '@astrojs/preact';
import react from '@astrojs/react';
import svelte from '@astrojs/svelte';
import vue from '@astrojs/vue';
import solid from '@astrojs/solid-js';
export default defineConfig({
// Enable many frameworks to support all different kinds of components.
// No `include` is needed if you are only using a single JSX framework!
integrations: [
preact({
include: ['**/preact/*'],
}),
react({
include: ['**/react/*'],
}),
solid({
include: ['**/solid/*'],
}),
],
});
```
