Cross-platform mobile apps: React Native best practices?

08 Tem 20:56

State management in React Native can get messy if you don't plan it early—trust me, I've seen projects spiral into spaghetti code with just Context API. For larger apps, I usually start with Zustand right away. The learning curve is minimal, it's lightweight, and scales way better than Redux for most use cases. Plus, the syntax is clean—no boilerplate action creators or reducers. I've used it in a few client projects where we had complex forms and real-time updates, and it handled everything smoothly without unnecessary re-renders. For project structure, I treat it like a mini monorepo approach. Group features by domain (e.g., `features/auth`, `features/payments`), keep shared logic in `lib`, and separate native modules if needed. Tooling like `react-native-module-federation` (yes, even in mobile) helps isolate components. I once worked on an app with 80k+ lines and having a clear file structure saved us countless hours debugging navigation hell. Also, don’t fear TypeScript—it pays off when your team grows.

For state management in larger React Native projects, I’ve mostly gravitated towards Redux Toolkit (RTK) paired with RTK Query for API interactions. It scales better than plain Redux with less boilerplate and the auto-generated hooks save a ton of manual work. Just be strict about keeping the slice logic clean and testable - that’s where most RTK setups start to bloat over time. As for project structure, I swear by the feature-based modular approach now. Everything related to a single feature (components, hooks, state, tests) sits together under its own directory, with shared utilities and config living in parallel folders. That way new devs can drop into a feature and immediately see the full workflow without hunting through an ever-growing web of folders. Haven’t tried Zustand yet, but colleagues who’ve migrated swear by the simplicity for smaller state needs.
