Introduction

react-native-kernel is an all-in-one, modular utility toolkit for React Native apps — similar in spirit to react-native-paper, but focused on system utilities, networking, and storage instead of UI components.

The goal is to replace 8–10 separate small npm installs with one well-typed, tree-shakeable package.

Design principles

• Zero unnecessary dependencies. The package has no runtime dependencies of its own — every feature is built directly on platform APIs (Keychain, Android Keystore, fetch, NWPathMonitor, ConnectivityManager, …).
• Full TypeScript, no any. Every hook, function, and native field is typed, including honest platform-limitation notes in doc comments (e.g. fields that are permission-gated or OS-restricted).
• Tree-shakeable subpaths. import ... from 'react-native-kernel/system' only bundles that module — importing kernel/storage never pulls in kernel/network.
• New Architecture only. Every native module is a TurboModule written against Codegen from day one. There is no legacy bridge fallback.

Modules

kernel/ui is the only module not listed above — it’s planned but not implemented yet, see the roadmap.

Import style

Every module is imported from its own subpath so unused modules aren’t bundled:

import { useNetwork, useDeviceInfo } from 'react-native-kernel/system';
import { createApiClient } from 'react-native-kernel/network';
import { SecureStorage, useOfflineSync } from 'react-native-kernel/storage';

There is no root-level react-native-kernel import — importing the package root exports nothing on purpose, to keep subpath imports honest about what they pull in.
