API Design helps shape predictable public APIs for TypeScript, JavaScript, React, and React Native libraries. Use it when designing exported functions, hooks, options objects, events, errors, or cross-platform abstractions.

Build Nitro Modules creates React Native Nitro Modules with Nitrogen specs, generated Swift/Kotlin/C++ bindings, and native stateful APIs. Use it when adding HybridObjects, Nitro View components, or the codegen pipeline.

C++ guides design, implementation, and review of modern C++ APIs and native code. Use it for .cpp, .hpp, CMake, ownership, async boundaries, and C++-backed React Native Nitro Modules.

Kotlin designs, implements, and reviews Kotlin and Android APIs for .kt files, nullability, sealed types, coroutines, threading, Java interop, and Kotlin-backed React Native Nitro Modules.

Nitro Fetch provides native-backed networking primitives for React Native, including fetch, WebSocket, TextDecoder, prefetching, and request inspection. Use it when you need faster cold starts, native sockets, or axios integration through the Nitro APIs.

React Native MMKV documents the synchronous key-value storage API for React Native apps. Use it to create instances, read and write values, manage listeners, handle encryption, and migrate from AsyncStorage.

React Native VisionCamera is a guide to setting up VisionCamera v5, migrating from v4, and using outputs, constraints, capture, recording, and basic frame processing. Use it when building or porting React Native camera screens.

React Native VisionCamera Realtime helps design and review low-latency VisionCamera v5 pipelines for GPU, ML, CV, Skia, and WebGPU overlays. Use it when frame budgets, zero-copy interop, and latency profiling matter.

Swift designs, implements, and reviews Swift APIs and Apple-platform code. Use it for .swift files, Swift concurrency, Foundation or AVFoundation APIs, and Swift-backed React Native Nitro Modules.
