Below is a conceptual **Markdown table** that contrasts different ways to use React and Astro together—covering client-side, server-side rendering (SSR), and embedding components. It also includes notes about **Vite configurations** and **plugins** you might need.

|
||
| **1. Astro + React (Client-side Only)** | Using React components within your Astro project, rendered exclusively on the client. | - *Client:* The browser executes the JavaScript.<br/>- *SSR:* The components are not rendered by the server; only HTML placeholders or minimal stubs are served. | 1. Install `@astrojs/react`. <br/>2. Import and register your React component in your `.astro` file. <br/>3. Use the `client:load`, `client:idle`, or `client:visible` directives for client hydration. | - **Vite config:** Astro automatically configures Vite for React by default when `@astrojs/react` is installed. <br/>- **Plugins:** The official `@astrojs/react` plugin handles bundling, transpilation, and client hydration. |
|
||
| **2. Astro + React (SSR)** | Using Astro’s server-side rendering (experimental or through a hosting platform that supports SSR) to **render React components on the server** before sending HTML to the client. | - *Client:* The component can then hydrate on the client if needed (otherwise it remains static, but pre-rendered from SSR). <br/>- *SSR:* React components are rendered by Astro’s SSR. | 1. Configure SSR in your `astro.config.mjs` or with your hosting provider’s settings. <br/>2. Make sure `@astrojs/react` is installed and your SSR environment is set up. <br/>3. Use SSR-friendly APIs (avoid browser-only globals in server code). | - **Vite config:** May need additional SSR config if your framework or deployment environment has special needs. <br/>- **Plugins:** Typically the same `@astrojs/react` plugin, but ensure any external SSR plugins are compatible (e.g. for styling or data-fetching). |
|
||
| **3. React Inside an Astro Component** | An `.astro` file that includes smaller React components inline, e.g., embedding `<ReactComponent />` inside Astro’s templating syntax. This is the most common scenario in Astro projects. | - *Client:* If the component is client-hydrated, it becomes interactive in the browser. <br/>- *SSR:* If Astro is set for SSR, the component is pre-rendered on the server. | 1. Create a `.astro` component. <br/>2. Import React components, e.g. `import MyButton from '../components/MyButton.jsx'`. <br/>3. Embed `<MyButton client:load />` or use another hydration directive. | - **Vite config:** Generally works out-of-the-box with `@astrojs/react`. <br/>- **Plugins:** Additional React-friendly Vite or Babel plugins can be added in your `astro.config.mjs` or in a separate config if needed. |
|
||
| **4. Astro Component inside React** | Less common scenario. You’d have a React application and want to render an Astro component within that React tree. Typically, you’d compile Astro into static output or use the Astro server output as an API (SSR). | - *Client:* If you bundle Astro components as static output, there’s no direct hydration for “Astro markup” inside React unless you embed them as iframes or separate routes. <br/>- *SSR:* Potentially possible, but complicated. | 1. **Static approach**: Build Astro pages/components to static HTML and embed via `<iframe>` or fetch the rendered content. <br/>2. **SSR approach**: Build an Astro SSR server and fetch rendered HTML from it. <br/>3. Integrating “live” Astro code directly in React bundlers is not straightforward. | - **Vite config:** React’s Vite config typically doesn’t parse `.astro` files. You may need custom integration or a multi-app approach. <br/>- **Plugins:** No out-of-the-box solution for Astro inside React. Consider separate builds or direct HTML consumption. |
|
||
| **5. Full React App with some Astro Pages** | A primarily React-based project, but certain pages or partial content is rendered by Astro (e.g., for static site generation or for speed). | - *Client:* React runs as usual. If Astro pages are served as static HTML, no direct hydration from Astro’s side unless specifically set up. <br/>- *SSR:* Varies based on hosting approach. | 1. Create a separate Astro project (or folder) for static pages. <br/>2. Configure your build/deployment to serve Astro pages separately. <br/>3. Link between React app and Astro-generated routes, passing data if necessary. | - **Vite config:** Possibly need separate Vite configs for React and Astro or a shared monorepo approach. <br/>- **Plugins:** Use the standard React Vite plugin for the main app, and `@astrojs/react` (and others) for the Astro portion. |

### Additional Notes
|
||
|
||
- **SSR (Server-Side Rendering) vs. Client-Side**:
|
||
- Astro’s default behavior is **static site generation** (SSG). If you need SSR, you must enable Astro’s SSR mode (experimental or through a supported deployment target like Vercel, Netlify, etc.).
|
||
- React can be mixed in for **partial hydration**, letting you deliver mostly static pages but with interactive “islands” of React.
|
||
|
||
- **Vite Configuration**:
|
||
- When using React inside Astro, the official `@astrojs/react` integration handles most details.
|
||
- If you have advanced needs (e.g., custom Babel transforms, PostCSS, or TypeScript paths), you can tweak Astro’s underlying Vite config in `astro.config.mjs`.
|
||
- For embedding Astro in a larger React project, or vice versa, consider **mono-repo** patterns or separate builds. Typically, each framework is built with its own config or pipeline.
|
||
|
||
- **Astro Components in a React Context**:
|
||
- Rendering `.astro` files “directly” inside a React build pipeline is not straightforward because React expects JavaScript/JSX while Astro components require the Astro compiler.
|
||
- Typically, it’s more straightforward to create **static exports** (HTML) from Astro and consume them in a React app or route to them.
|
||
|
||
- **Hydration Directives**:
|
||
- Astro’s special directives like `client:load`, `client:idle`, and `client:visible` determine when/how a React component hydrates on the client.
|
||
- For SSR, if you want a component to remain static, do not add a client directive, and it will render in pure HTML.
|

Use the table and notes above to guide how you structure your Astro + React workflow, deciding whether your components render on the client, server, or a bit of both.
