## What it is
A toolchain implementing the Performance API for React Native, enabling measurement of app performance in development, CI pipelines, and production. It traces arbitrary events, component render times, network traffic, and native metrics, with devtools integration via Rozenite.

## Use cases
- measure react native app performance
- trace component render times in react native
- monitor time to interactive for native screens
- capture network traffic performance metrics
- collect js bundle size metrics in development
- use performance api across web and react native

## When to choose
- you need standardized Performance API instrumentation in a React Native app
- you want to measure performance across development, CI, and production
- your app targets both web and native and needs an isomorphic performance API

## When to avoid
- you need profiling for plain web or native iOS/Android apps without React Native
- you rely on Flipper, which is deprecated
- you want automated crash or error monitoring rather than performance metrics

## Facets
- artifact type: library
- maturity: active
- function: monitoring, benchmarking, tracing
- domain: mobile-development, performance, developer-tools
- platform: browser
- tags: react-native, performance-api, metrics, devtools, typescript, mobile, ios, android, nodejs
