## What it is
rnx-kit is a collection of React Native developer tools maintained by Microsoft, including an all-in-one CLI, dependency alignment (align-deps), enhanced Metro bundling, and cloud native builds. It fills gaps in the React Native ecosystem and streamlines workflows for projects of any size.

## Use cases
- align dependency versions across a large react native monorepo
- add tree shaking and duplicate dependency detection to metro bundling
- build android and ios apps in the cloud without native toolchains
- set up a react native cli toolchain for my project
- detect cyclic dependencies in my react native app
- manage react native dependencies in typescript projects

## When to choose
- you maintain a large or monorepo react native codebase needing consistent dependency versions
- you want enhanced metro bundling with validation and tree shaking
- you want to avoid installing heavy native build toolchains
- you want battle-tested tooling used at Microsoft scale

## When to avoid
- you have a small react native app with simple tooling needs
- you don't use react native at all
- you need fully stable cloud native builds, which are still experimental
