Overview

Brownie provides cross-platform shared state for React Native brownfield apps. The workflow starts from *.brownie.ts store definitions, runs brownfield codegen (or packaging commands that include codegen), then uses typed APIs on TypeScript, Android, and iOS sides.

When to Apply

Reference this skill when:

• Setting up @callstack/brownie in an existing brownfield app
• Defining or changing store schemas in *.brownie.ts
• Using useStore, subscribe, getSnapshot, or setState on the JS side
• Registering and consuming stores in Android or iOS hosts
• Packaging and embedding iOS frameworks that include Brownie
