Who it's for

Full-stack TypeScript developers who have shipped at least one React app and want to build a production mobile app without learning Swift, Kotlin, or a second backend language.

About this playbook

If you're a TypeScript developer who knows React and wants to ship a real mobile app — not a tutorial to-do list — this is the stack that gets you there fastest. You'll build with TanStack Start on the server, oRPC for the type-safe API layer, Supabase for auth and database, Expo React Native for the mobile client, and deploy everything to Cloudflare Workers. Every phase uses Claude Code to accelerate — not replace — the work, from scaffolding to debugging to deployment. I've shipped five apps on this stack and the mistakes I made (misconfigured API base URL that cost a weekend, RLS policies I forgot applied differently server-side) are the warnings in here. Advanced-level. You need TypeScript and React fluency, but nothing mobile-specific coming in.

Phase 1: Scaffold the monorepo and toolchain

0/3

Get the skeleton right from day one. A pnpm monorepo with clean package boundaries saves you the rewrite I did halfway through my first project — the web app, mobile app, and shared domain code each live in their own workspace package, and the type-safe API contract lives alongside domain types in the shared package, imported by both apps.

Phase 2: Define and serve the API contract with oRPC

0/3

This is the phase that makes the rest of the project fast. oRPC gives you a type-safe contract that both the web SSR renderer and the mobile app import from a single source of truth — no manual API clients, no runtime validation mismatches, no 'the web version works but the mobile response format is different' bugs.
