Hi @strange geyser. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

#

Astro provides an adapter called @astrojs/node that allows you to deploy your server-side rendered (SSR) Astro site to Node targets. This adapter can be used either in standalone mode or as middleware for other HTTP servers, such as Express.js. However, the specific details or code examples on how to use Express.js with Astro are not provided in the given extracts.

For more information, you can refer to the Astro documentation (https://docs.astro.build/en/guides/integrations-guide/node).

Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

@crude folio are there any other examples of how i could do this?

Let me check the knowledge base for you. One moment! :books:

#

Yes, there is an example provided in the extracts on how to use Express.js with Astro. Here's the code snippet:

import express from 'express';
import { handler as ssrHandler } from './dist/server/entry.mjs';

const app = express();
// Change this based on your astro.config.mjs, `base` option.
// They should match. The default value is "/".
const base = '/';
app.use(base, express.static('dist/client/'));
app.use(ssrHandler);

app.listen(8080);

In this example, an Express.js server is created and the Astro server-side rendering handler is imported from ./dist/server/entry.mjs. The Express.js server is then configured to serve static files from the dist/client/ directory and to use the Astro SSR handler for all other requests. Finally, the server is started on port 8080.

You can find more details in the Astro documentation (https://docs.astro.build/en/guides/integrations-guide/node#middleware).

@crude folio in what file would you put the code snippet?

Let me check the knowledge base for you. One moment! :books:

#

The code snippet would typically be placed in a server setup file in your project's root directory. This file is often named server.js or server.mjs.

Here's an example of how you might structure it:

// server.mjs
import express from 'express';
import { handler as ssrHandler } from './dist/server/entry.mjs';

const app = express();
const base = '/';
app.use(base, express.static('dist/client/'));
app.use(ssrHandler);

app.listen(8080);

Then, you can start your server by running node server.mjs in your terminal.

Please note that the exact file and directory structure can depend on your specific project setup.

@crude folio what is the './dist/server/entry.mjs' supposed to be

crude folioBOT
#

Let me check the knowledge base for you. One moment! :books:

#

The ./dist/server/entry.mjs file is the server entry point for your Astro application. When you build your Astro project for server-side rendering (SSR), this file is automatically generated in the dist/server/ directory.

This entry.mjs module exports a handler function that can be used with any framework that supports the Node request and response objects, such as Express.js.

You can start a server by importing this module in your Deno app or run the script directly using deno or node. For example:

import './dist/entry.mjs';

or

deno run --allow-net --allow-read --allow-env ./dist/server/entry.mjs

or

node ./dist/server/entry.mjs

You can find more details in the Astro documentation (https://docs.astro.build/en/guides/integrations-guide/deno#usage).

@crude folio so does server.js work along side the pages folder, components, etc.?

crude folioBOT
#

Let me check the knowledge base for you. One moment! :books:

#

Yes, the server.js file works alongside the pages, components, and other directories in your Astro project.

The server.js file is responsible for setting up and running your server, including serving static files and handling server-side rendering via Astro's SSR handler.

Meanwhile, the pages directory contains your website's pages, and the components directory contains reusable components. These directories are part of Astro's project structure and are used to generate the HTML, CSS, and client-side JavaScript that your server will serve.

When you run your Astro build command, Astro generates the dist directory which includes the server/entry.mjs file for server-side rendering and the client/ directory for static files. These are the files that your Express.js server defined in server.js will serve.

Here's a simplified view of what your project structure might look like:

/my-astro-project
├── src/
│   ├── components/
│   ├── pages/
│   └── ...
├── dist/
│   ├── client/
│   ├── server/
│   │   └── entry.mjs
│   └── ...
├── server.js
└── ...

You can find more details about Astro's project structure in the Astro documentation (https://docs.astro.build/en/core-concepts/project-structure).
