Expo + Hono for mobile SaaS
Build a cross‑platform Expo app powered by a fast, edge‑ready Hono API. Ship mobile experiences with globally distributed endpoints, modern TypeScript DX, and production‑grade patterns.
What you get
- Cross‑platform app: Expo + React Native with TypeScript
- Edge API: Hono routes designed for Vercel Edge, Cloudflare Workers, or Deno
- Auth‑ready: Session and token patterns suitable for mobile clients
- Monorepo workflow: Shared types, utilities, and consistent tooling
- Prod essentials: Env management, linting, and CI‑friendly structure
Architecture at a glance
The starter separates concerns cleanly: the Expo app handles UI and device capabilities, while Hono exposes lightweight, cache‑friendly endpoints close to users. This reduces latency, simplifies scaling, and keeps your API portable across edge platforms.
Use shared TypeScript types between Expo and Hono to ensure end‑to‑end type safety and fewer runtime bugs.
Quick start overview
Add API base URL, auth secrets, and platform keys to your environment files.
Start the Hono API, then run the Expo app in iOS Simulator, Android, or web.
Publish the API to your preferred edge runtime and point the app to the live URL.
Common use cases
- Real‑time apps: Chat, presence, and activity streams with edge‑proxied APIs
- Content + AI: On‑device capture with server‑side AI orchestration
- B2B SaaS: Authenticated org flows with minimal latency worldwide
Best practices
- Keep responses small and cacheable where safe for speed and cost savings.
- Prefer stateless endpoints; use signed tokens or short‑lived sessions.
- Log structured events at the edge for observability without heavy overhead.
Deployment & scaling
- Start with a single edge provider, add multi‑provider later if needed.
- Use canary routes or feature flags to test new API versions safely.
- Monitor p95/p99 latency from real devices to catch regional regressions.
