@astrojs/deno 🦖
This adapter allows Astro to deploy your SSR site to Deno targets.
Learn how to deploy your Astro site in our Deno Deploy deployment guide.
Why Astro Deno
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), Astro requires an adapter that matches your deployment runtime.
Deno is a runtime similar to Node, but with an API that's more similar to the browser's API. This adapter provides access to Deno's API and creates a script to run your project on a Deno server.
Installation
Add the Deno adapter to enable SSR in your Astro project with the following astro add
command. This will install the adapter and make the appropriate changes to your astro.config.mjs
file in one step.
# Using NPM
npx astro add deno
# Using Yarn
yarn astro add deno
# Using PNPM
pnpm astro add deno
If you prefer to install the adapter manually instead, complete the following two steps:
-
Install the Deno adapter to your project’s dependencies using your preferred package manager. If you’re using npm or aren’t sure, run this in the terminal:
npm install @astrojs/deno
-
Update your
astro.config.mjs
project configuration file with the changes below.// astro.config.mjs import { defineConfig } from 'astro/config'; import deno from '@astrojs/deno'; export default defineConfig({ output: 'server', adapter: deno(), });
Next, update your preview
script in package.json
to run deno
:
// package.json
{
// ...
"scripts": {
"dev": "astro dev",
"start": "astro dev",
"build": "astro build",
"preview": "deno run --allow-net --allow-read --allow-env ./dist/server/entry.mjs"
}
}
You can now use this command to preview your production Astro site locally with Deno.
npm run preview
Usage
After performing a build there will be a dist/server/entry.mjs
module. You can start a server by importing this module in your Deno app:
import './dist/entry.mjs';
See the start
option below for how you can have more control over starting the Astro server.
You can also run the script directly using deno:
deno run --allow-net --allow-read --allow-env ./dist/server/entry.mjs
Configuration
To configure this adapter, pass an object to the deno()
function call in astro.config.mjs
.
astro.config.mjs
import { defineConfig } from 'astro/config';
import deno from '@astrojs/deno';
export default defineConfig({
output: 'server',
adapter: deno({
//options go here
})
});
start
This adapter automatically starts a server when it is imported. You can turn this off with the start
option:
import { defineConfig } from 'astro/config';
import deno from '@astrojs/deno';
export default defineConfig({
output: 'server',
adapter: deno({
start: false
})
});
If you disable this, you need to write your own Deno web server. Import and call handle
from the generated entry script to render requests:
import { serve } from "https://deno.land/std@0.167.0/http/server.ts";
import { handle } from './dist/entry.mjs';
serve((req: Request) => {
// Check the request, maybe do static file handling here.
return handle(req);
});
port and hostname
You can set the port (default: 8085
) and hostname (default: 0.0.0.0
) for the deno server to use. If start
is false, this has no effect; your own server must configure the port and hostname.
import { defineConfig } from 'astro/config';
import deno from '@astrojs/deno';
export default defineConfig({
output: 'server',
adapter: deno({
port: 8081,
hostname: 'myhost'
})
});
Examples
The Astro Deno example includes a preview
command that runs the entry script directly. Run npm run build
then npm run preview
to run the production deno server.
