How to Deploy Astro to Vercel: Step-by-Step Guide

To deploy an Astro project to Vercel, first create a Vercel account and install the Vercel CLI. Then, run vercel in your project folder to deploy, following the prompts to configure your deployment. Vercel automatically detects Astro and builds your site for you.

Syntax

Deploying Astro to Vercel mainly uses the vercel command in your project folder. The basic syntax is:

• vercel: Starts the deployment process interactively.
• vercel --prod: Deploys directly to production without prompts.
• vercel --confirm: Skips confirmation prompts for automated deployment.

Vercel detects your astro.config.mjs and builds your site accordingly.

bash

vercel
vercel --prod
vercel --confirm

Example

This example shows how to deploy a simple Astro project to Vercel using the CLI.

After creating your Astro project and installing dependencies, run vercel in the project root. Follow the prompts to link or create a new Vercel project. Vercel will build and deploy your site, then provide a URL to view it live.

bash

npm create astro@latest my-astro-site
cd my-astro-site
npm install
vercel

Output

Vercel CLI 28.0.0
? Set up and deploy “my-astro-site”? [Y/n] y
? Which scope do you want to deploy to? YourName
? Link to existing project? [y/N] n
? What’s your project’s name? my-astro-site

Common Pitfalls

Some common mistakes when deploying Astro to Vercel include:

• Not running npm install before deploying, causing build failures.
• Missing astro.config.mjs or misconfigured build settings.
• Using an outdated Vercel CLI version.
• Not setting the correct build command or output directory in Vercel settings (usually npm run build and dist).

Always check your package.json scripts and Vercel project settings if deployment fails.

    "dev": "astro dev",
    "build": "astro build",
    "preview": "astro preview"
  }
}
