Deploy your Astro Site to Vercel

本頁內容尚未翻譯。

You can use Vercel to deploy an Astro site to their global edge network with zero configuration.

This guide includes instructions for deploying to Vercel through the website UI or Vercel’s CLI.

Project Configuration

Your Astro project can be deployed to Vercel as a static site, or as a server-side rendered site (SSR).

Static Site

Your Astro project is a static site by default. You don’t need any extra configuration to deploy a static Astro site to Vercel.

Adapter for SSR

To enable SSR in your Astro project and deploy on Vercel:

Add the Vercel 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.

npx astro add vercel

If you prefer to install the adapter manually instead, complete the following two steps:

Install the @astrojs/vercel 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:
Terminal window
```
  npm install @astrojs/vercel
```

Add two new lines to your astro.config.mjs project configuration file.

import { defineConfig } from 'astro/config';
import vercel from '@astrojs/vercel/serverless';

export default defineConfig({
  output: 'server',
  adapter: vercel(),
});

How to deploy

You can deploy to Vercel through the website UI or using Vercel’s CLI (command line interface). The process is the same for both static and SSR Astro sites.

Website UI Deployment

Push your code to your online Git repository (GitHub, GitLab, BitBucket).
Import your project into Vercel.
Vercel will automatically detect Astro and configure the right settings.
Your application is deployed! (e.g. astro.vercel.app)

After your project has been imported and deployed, all subsequent pushes to branches will generate Preview Deployments, and all changes made to the Production Branch (commonly “main”) will result in a Production Deployment.

CLI Deployment

Install the Vercel CLI and run vercel to deploy.
Terminal window
```
npm install -g vercel
vercel
```
Vercel will automatically detect Astro and configure the right settings.
When asked Want to override the settings? [y/N], choose N.
Your application is deployed! (e.g. astro.vercel.app)

Project config with vercel.json

You can use vercel.json to override the default behavior of Vercel and to configure additional settings. For example, you may wish to attach headers to HTTP responses from your Deployments.

Upgrading to Astro 2.0

Astro v2.0 drops support for Node 14, so make sure your project is using Node 18.14.1 or later. You can define the Node.js version used during the Build Step and Serverless Functions from the General page under Project Settings.
