As a solo developer, you are the architect, the engineer, and the future maintainer — all at once. The decisions you make about folder layout and library choices in week one will either speed you up or slow you down for the life of the project. React Native gives you almost no opinions on structure, which is both a gift and a trap.

The good news: in 2026, the React Native ecosystem has converged on a set of patterns and tools that work well for individuals. With Expo SDK 56 (built on React Native 0.85 and React 19.2), released May 21, 2026, you can ship to iOS and Android without juggling separate native toolchains, and a small set of libraries covers nearly every common need.
Quick Answer
Start with Expo SDK 56, organize your code inside a src/ folder using a type-based structure — screens/, components/, hooks/, services/, store/ — then add Zustand for local state, TanStack Query for server data, and Expo Router for file-based routing. Keep things flat until a feature grows large enough to deserve its own subfolder.
Choose Your Starting Point: Expo, Not Bare CLI
For a solo developer, Expo is the right call for 95% of projects. Expo SDK 56 ships with React Native 0.85 and React 19.2, with Hermes v1 now the default JavaScript engine — delivering faster cold starts and lower memory usage out of the box. EAS Build means you can compile and submit iOS builds without owning a Mac, and the SDK covers cameras, push notifications, biometrics, and most other native capabilities without ever opening Xcode or Android Studio. SDK 56 also promotes Expo UI — with stable Jetpack Compose (Android) and SwiftUI (iOS) primitives — into the default create-expo-app template, giving you native-quality UI components from day one.
Only reach for the bare React Native CLI if you need a native SDK that Expo does not support, or if you are embedding React Native into an existing native app. Otherwise the configuration overhead is simply not worth it for someone working alone.
Folder Structure: Two Patterns, One Clear Starting Point
For most new projects, start with a type-based structure inside a src/ directory. Inside src/ you want these folders: assets/ for images and fonts, components/ for reusable UI elements, screens/ for each app screen, navigation/ for route configuration, hooks/ for custom React hooks, services/ for API calls, store/ for state management, utils/ for helper functions, and constants/ for app-wide values like strings and config keys. Keep App.tsx and index.tsx at the project root. On day one, add TypeScript path aliases in tsconfig.json — mapping @components to src/components, @screens to src/screens, and so on — so you never write a four-level relative import like ../../../../components/Button again.
Switch to a feature-based structure only when a single domain — auth, feed, profile — grows beyond roughly five files and has its own screens, hooks, and API logic. In that pattern, src/features/ holds one subfolder per feature, and each feature folder contains its own components/, screens/, hooks/, and an api.ts file. A src/shared/ folder holds anything used across features. Do not start here — pre-optimizing an architecture for an app that barely exists yet is one of the most common time-sinks for solo developers.
Pick Your Core Libraries and Commit
For routing, use Expo Router if you are starting fresh with Expo in 2026. As of SDK 56, Expo Router no longer depends on React Navigation — it has forked into its own independent routing layer. This means importing anything from @react-navigation/* in an Expo Router project will break; migrate to Expo Router’s own APIs instead. If you prefer explicit route definitions and are not using Expo’s managed workflow, React Navigation remains a strong standalone option, but pick one and do not switch mid-project.
For state management, the 2026 consensus is Zustand for local client state and TanStack Query (React Query) for server state. Zustand is minimal, hook-based, and has almost no boilerplate compared to Redux. TanStack Query handles fetching, caching, background refetching, and loading and error states automatically. Use React Context only for global data that rarely changes, such as the authenticated user object or the current theme.
TypeScript is not optional. Enabling it from project creation costs nothing and pays dividends when you return to the codebase three months later trying to remember what shape an API response has. The Expo SDK 56 default template generates a tsconfig.json for you. Do not override anything with any — it defeats the entire purpose.
Tips and Common Mistakes
Do not start with Redux. Redux Toolkit is solid for large teams with complex shared state, but its boilerplate is a tax on solo developers. Zustand plus TanStack Query covers what most apps actually need, and you can always migrate later if complexity demands it.
Do not put business logic in screen components. Screens should call hooks and render JSX — nothing else. Extract data transformation, validation, and side-effect logic into a custom hook or a services/ function so it can be tested and reused without touching the screen.
If you are on Expo SDK 56 with Expo Router, do not import from @react-navigation/* — those imports are broken as of this release. Expo Router is now fully independent, so rely on its own navigation primitives and documentation rather than React Navigation’s.
Do not over-engineer the structure before you have enough code. If your entire app is four screens and ten components, a flat components/ folder and a flat screens/ folder is the correct structure. Folder complexity should reflect real code complexity, not imagined future complexity.

React Native app structure FAQs
Should I use Expo or the bare React Native CLI as a solo developer?
Use Expo. In 2026, Expo SDK 56 covers nearly every native capability a typical app needs, lets you build iOS apps without a Mac via EAS Build, and eliminates most native configuration work. Bare CLI is only worth the overhead if you need a specific native SDK that Expo does not yet support.
When should I switch from a type-based to a feature-based folder structure?
When a single domain — such as authentication or a social feed — grows beyond roughly five files and has its own screens, hooks, and API logic that only belong to it. Start type-based and migrate individual domains to a features/ subfolder one at a time as the need becomes obvious.
Do I need Redux for a React Native app I am building alone?
No. Zustand handles local client state with far less boilerplate, and TanStack Query manages all server state including caching and background sync. Redux Toolkit is a strong choice for large teams, but for a solo project it adds configuration overhead without a meaningful benefit.
