Shopify App Deployment Strategy

Deploying Shopify apps is different from standard websites because of Webhooks, Admin API Rate Limits, and OAuth handshakes.

1. The "Vercel Problem" (Timeouts)

Vercel Serverless functions have a timeout (usually 10s-60s).

• Issue: Shopify bulk operations, product syncs, or installing the app on a large store can take >60s.
• Result: 504 Gateway Timeout and broken installs.

Solution A: Remix on Vercel (Hybrid)

• Use Vercel for the UI.
• Offload long tasks (syncing) to a separate worker (Cloudflare Workers, Inngest, or separate VPS).
• Use Defer in Remix to stream UI while backend works (but doesn't fix hard timeouts for the main thread).

Solution B: VPS / Docker (Recommended for Serious Apps)

Deploying to a persistent server (Fly.io, Railway, DigitalOcean, Hetzner) eliminates timeouts.

• Tooling: Coolify (self-hosted Vercel alternative), Dokku, or manual Docker.
