SvelteKit deployment best practices

Here are essential tips for deploying SvelteKit applications effectively, especially when using Railway.com with adapter-node.

Always set your environment variables properly in production:

# Essential variables for Railway deployment
NODE_ENV=production
PORT=3000
ORIGIN=https://your-app.railway.app

Consider adding basic health checks and monitoring to ensure your deployment is running smoothly:

// src/routes/health/+server.ts
export async function GET() {
	return new Response('OK', { status: 200 });
}

Don’t forget to configure security headers in your deployment for production apps. Railway makes this easy with their built-in security features.

These practices will help ensure your SvelteKit app deploys reliably and performs well in production.
