## Why Astro Node
|
|
|
|
If you're using Astro as a static site builder—its behavior out of the box—you don't need an adapter.
|
|
|
|
If you wish to [use server-side rendering (SSR)](https://docs.astro.build/en/guides/server-side-rendering/), Astro requires an adapter that matches your deployment runtime.
|
|
|
|
[Node](https://nodejs.org/en/) is a JavaScript runtime for server-side code. Frameworks like [Express](https://expressjs.com/) are built on top of it and make it easier to write server applications in Node. This adapter provides access to Node's API and creates a script to run your Astro project that can be utilized in Node applications.
|
|
|
|
## Installation
|
|
|
|
First, install the `@astrojs/node` package using your package manager. If you're using npm or aren't sure, run this in the terminal:
|
|
|
|
```sh
|
|
npm install @astrojs/node
|
|
```
|
|
|
|
Then, install this adapter in your `astro.config.*` file using the `adapter` property:
|
|
|
|
__`astro.config.mjs`__
|
|
|
|
```js
|
|
import { defineConfig } from 'astro/config';
|
|
import node from '@astrojs/node';
|
|
|
|
export default defineConfig({
|
|
// ...
|
|
output: 'server',
|
|
adapter: node()
|
|
})
|
|
```
|
|
|
|
## Usage
|
|
|
|
After [performing a build](https://docs.astro.build/en/guides/deploy/#building-your-site-locally) there will be a `dist/server/entry.mjs` module that exposes a `handler` function. This works like a [middleware](https://expressjs.com/en/guide/using-middleware.html) function: it can handle incoming requests and respond accordingly.
|
|
|
|
|
|
### Using a middleware framework
|
|
You can use this `handler` with any framework that supports the Node `request` and `response` objects.
|
|
|
|
For example, with Express:
|
|
|
|
```js
|
|
import express from 'express';
|
|
import { handler as ssrHandler } from './dist/server/entry.mjs';
|
|
|
|
const app = express();
|
|
app.use(express.static('dist/client/'))
|
|
app.use(ssrHandler);
|
|
|
|
app.listen(8080);
|
|
```
|
|
|
|
|
|
### Using `http`
|
|
|
|
This output script does not require you use Express and can work with even the built-in `http` and `https` node modules. The handler does follow the convention calling an error function when either
|
|
|
|
- A route is not found for the request.
|
|
- There was an error rendering.
|
|
|
|
You can use these to implement your own 404 behavior like so:
|
|
|
|
```js
|
|
import http from 'http';
|
|
import { handler as ssrHandler } from './dist/server/entry.mjs';
|
|
|
|
http.createServer(function(req, res) {
|
|
ssrHandler(req, res, err => {
|
|
if(err) {
|
|
res.writeHead(500);
|
|
res.end(err.toString());
|
|
} else {
|
|
// Serve your static assets here maybe?
|
|
// 404?
|
|
res.writeHead(404);
|
|
res.end();
|
|
}
|
|
});
|
|
}).listen(8080);
|
|
```
|
|
|
|
|
|
|
|
