Migrating Astro from Vercel to AWS Fargate

If you are seeing a warning from deploy-stack about your Astro adapter, it means your project is currently configured to build specifically for Vercel’s proprietary serverless network.

To deploy Astro as a containerized application on standard AWS infrastructure, you simply need to switch to Astro’s official Node.js adapter.

How to Fix

1. Install the Node adapter

Run the following command in your terminal to swap out the Vercel adapter for the Node adapter:

```bash npm install @astrojs/node npm uninstall @astrojs/vercel ```

2. Update astro.config.mjs

Open your Astro configuration file and replace the Vercel import with the Node import.

Before (Vercel Lock-in): ```javascript import { defineConfig } from ‘astro/config’; import vercel from ‘@astrojs/vercel/serverless’;

export default defineConfig({ output: ‘server’, adapter: vercel(), }); ```

After (AWS Ready): ```javascript import { defineConfig } from ‘astro/config’; import node from ‘@astrojs/node’;

export default defineConfig({ output: ‘server’, adapter: node({ mode: ‘standalone’ }), }); ```

3. Deploy

That’s it! Your Astro app is now decoupled from Vercel.

Run npx deploy-stack apply and the CLI will automatically package this standalone Node server into a hardened Docker container and deploy it to your AWS cluster.
