With the documentation split between: https://docs.solidjs.com and https://start.solidjs.com, it can be confusing to find what you’re looking for. Heres things that I often find myself searching for.

Deploying to Vercel

// app.config.ts
export default defineConfig({
  server: {
    preset: 'vercel'
  }
});

If you are deploying to multiple locations, vercel always injects process.env.VERCEL.
