## What it is
CRN (Ctrip React Native) is a customized fork of React Native 0.59 optimized by Ctrip's mobile platform team for better stability and faster first-screen loading. It includes a CLI scaffolding tool (crn-cli), framework/business code splitting, background preloading, and unified iOS/Android bundle output.

## Use cases
- speed up react native app startup time
- split react native framework code from business code
- build one react native bundle for both ios and android
- preload react native framework in background
- lazy load javascript modules in react native
- stabilize react native on android with error handling
- scaffold a react native project with crn-cli

## When to choose
- you are building a large-scale React Native app and need faster first-screen load times
- you want a single JS bundle shared across iOS and Android
- you need framework/business code splitting and background preloading in RN

## When to avoid
- you need the latest React Native features, since CRN is based on RN 0.59 (2019)
- you are starting a small new project where official React Native is sufficient
- you need active community support, as the project has seen no releases since 2020
