adapter-vercel
Deploys to Vercel's edge or serverless functions automatically.
npm install -D @sveltejs/adapter-vercelVercel Detection
adapter-auto picks adapter-vercel when deployed on Vercel; explicit install gives more control.
Edge vs Node
Vercel adapter supports both edge (faster cold start) and node runtimes per route.
export const config = { runtime: "edge" };adapter-cloudflare
Deploys to Cloudflare Pages with Workers for SSR and APIs.
npm install -D @sveltejs/adapter-cloudflareCloudflare Pages
Connect your repo to Cloudflare Pages; the adapter handles the rest.
Edge Performance
Edge functions run close to users globally, reducing latency.
Limitations
Edge runtimes lack full Node APIs (no fs, no native modules). Plan accordingly.
Env Vars
Use the dashboard or wrangler.toml for Cloudflare; Vercel uses project env vars.
Logs and Observability
Both providers offer real-time logs and metrics from their dashboards.
Preview Deployments
Both create preview URLs for every PR, great for reviews.
Cost
Free tiers are generous for small projects; paid tiers scale based on usage.
