React Native Development: What It's Like Working With a Specialist Team

“React Native development” covers a wide range of actual practice — from a single developer bolting a mobile wrapper onto a web app, to a specialist team running a mature, production-grade stack. Here’s what the latter actually looks like.

Expo, not bare React Native

Nearly all serious React Native work today runs on Expo — not the old “Expo Go” limited sandbox, but Expo’s full development build system, which gives you native module support, over-the-air JavaScript updates (Expo Updates), and EAS Build for cloud-based iOS and Android builds without needing a local Xcode/Android Studio setup for every developer on the team. Building bare React Native without Expo’s tooling is rarely worth the tradeoff today unless there’s a very specific reason not to use it.

The Bridgeless architecture matters

React Native 0.74+ ships the “Bridgeless” architecture (built on the New Architecture’s JSI, replacing the old asynchronous JS-to-native bridge with direct, synchronous communication). This is the change that quietly resolved most of React Native’s historical performance reputation — a team running on a current React Native version is working with meaningfully different performance characteristics than what “React Native” implied a few years ago.

The rest of a production stack

• TypeScript — not optional for anything beyond a prototype; catches an entire category of runtime errors before they ship.
• React Navigation — the standard routing/navigation library, handling stack, tab, and drawer navigation patterns.
• Zustand or Redux Toolkit — for state that needs to be shared across the app, with Zustand generally preferred today for its much smaller API surface.
• React Query — for server state specifically (data fetched from an API), handling caching, refetching, and loading states in a way that’s easy to get subtly wrong if hand-rolled.
• Reanimated — for animations that need to run on the native thread rather than the JS thread, avoiding jank during heavy JS work.
• Jest and Detox — unit testing and end-to-end testing respectively; Detox specifically drives the app on a real simulator/device, catching integration issues unit tests can’t.

What a release cycle actually looks like

EAS Build produces signed iOS and Android binaries in the cloud. For most changes — anything that’s pure JavaScript, not a native module change — Expo Updates can push the new bundle directly to users’ installed apps without going through App Store or Play Store review at all, which is a genuine advantage for fixing bugs fast. Native-level changes (new permissions, new native dependencies) still require a full store submission and review cycle like any native app.

Team and timeline expectations

A focused React Native team can typically get a mid-complexity app (the kind with real backend integration, auth, and a dozen-plus screens) to a first release in a few months, materially faster than building the same scope twice as separate native iOS and Android apps — see our app development cost guide for how that timeline translates to budget ranges.

Elmeris runs exactly this stack — Expo, the Bridgeless architecture, EAS Build — as our default React Native setup. See our React Native development services, or get in touch to scope your project.
