Deploy your Astro Site with Deno
本頁內容尚未翻譯。
You can deploy a static or on-demand rendered Astro site using Deno, either on your own server, or to Deno Deploy, a distributed system that runs JavaScript, TypeScript, and WebAssembly at the edge, worldwide.
This guide includes instructions for running your Astro site on your own server with Deno, and deploying to Deno Deploy through GitHub Actions or the Deno Deploy CLI.
Requirements
This guide assumes you already have Deno installed.
Project Configuration
Your Astro project can be deployed as a static site, or as an on-demand rendered site.
Static Site
Your Astro project is a static site by default. You don’t need any extra configuration to deploy a static Astro site with Deno, or to Deno Deploy.
Adapter for on-demand rendering
To enable on-demand rendering in your Astro project using Deno, and to deploy on Deno Deploy:
Install the
@deno/astro-adapteradapter to your project’s dependencies using your preferred package manager:npm install @deno/astro-adapterpnpm install @deno/astro-adapteryarn add @deno/astro-adapterUpdate your
astro.config.mjsproject configuration file with the changes below.// astro.config.mjs import { defineConfig } from 'astro/config'; import deno from '@deno/astro-adapter'; export default defineConfig({ output: 'server', adapter: deno(), });Update your
previewscript inpackage.jsonwith the change below.// package.json { // ... "scripts": { "dev": "astro dev", "start": "astro dev", "build": "astro build", "preview": "astro preview" "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 previewpnpm run previewyarn run preview
How to deploy
You can run your Astro site on your own server, or deploy to Deno Deploy through GitHub Actions or using Deno Deploy’s CLI (command line interface).
On your own server
Copy your project onto your server.
Install the project dependencies using your preferred package manager:
npm installpnpm installyarnBuild your Astro site with your preferred package manager:
npm run buildpnpm run buildyarn run buildStart your application with the following command:
deno run -A jsr:@std/http/file-server distdeno run -A ./dist/server/entry.mjs
GitHub Actions Deployment
If your project is stored on GitHub, the Deno Deploy website will guide you through setting up GitHub Actions to deploy your Astro site.
Push your code to a public or private GitHub repository.
Sign in on Deno Deploy with your GitHub account, and click on New Project.
Select your repository, the branch you want to deploy from, and select GitHub Action mode. (Your Astro site requires a build step, and cannot use Automatic mode.)
In your Astro project, create a new file at
.github/workflows/deploy.ymland paste in the YAML below. This is similar to the YAML given by Deno Deploy, with the additional steps needed for your Astro site.--- // .github/workflows/deploy.yml --- name: Deploy on: [push] jobs: deploy: name: Deploy runs-on: ubuntu-latest permissions: id-token: write # Needed for auth with Deno Deploy contents: read # Needed to clone the repository steps: - name: Clone repository uses: actions/checkout@v4 # Not using npm?

You can track the progress using the "Actions" tab on your GitHub repository page, or on Deno Deploy.
CLI Deployment
Install the Deno Deploy CLI.
deno install -gArf jsr:@deno/deployctlBuild your Astro site with your preferred package manager:
npm run buildpnpm run buildyarn run buildRun
deployctlto deploy!cd dist && deployctl deploy jsr:@std/http/file-serverdeployctl deploy ./dist/server/entry.mjsYou can track all your deploys on Deno Deploy.
(Optional) To simplify the build and deploy into one command, add a
deploy-denoscript inpackage.json.// package.json { // ... "scripts": { "dev": "astro dev", "start": "astro dev", "build": "astro build", "preview": "astro preview", "deno-deploy": "npm run build && cd dist && deployctl deploy jsr:@std/http/file-server" } }// 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", "deno-deploy": "npm run build && deployctl deploy ./dist/server/entry.mjs" } }Then you can use this command to build and deploy your Astro site in one step.
npm run deno-deploy
