How to deploy:

1. Fork this repository.
2. Log in to your Vercel account (or create one).
3. Add your fork on Vercel's dashbaord with following settings:
   • FRAMEWORK PRESET should be Vite. (Vercel should automatically detect Vite; just make sure it's already set.)
   • Modify Build and Output Settings > OUTPUT DIRECTORY from dist to dist/client.

That's it, your fork is now deployed on Vercel (it should look like vite-plugin-ssr-demo.vercel.app). It's continuously deployed: if you commit and push a change to your fork, then Vercel automatically re-deploys your app.

Integration points:

• API Route: api/ssr.js.
• Routing URLs to api/ssr.js: vercel.json#rewrites.
• Build: the package.json's scripts package.json#scripts['vercel-build'] and package.json#scripts.build.
• Development: the package.json's script package.json#scripts.dev; we use Vite's development server for improved DX.

👉 Vercel runs our API Route api/ssr.js as a serverless function, for more information see Vercel Docs > Serverless Functions > Deploying.
