React Native application

Overview

Opinionated ecosystem for building Expo/React Native apps with a consistent architecture, library stack, and UI system (

src/ui

Tech stack

Layer	Choice
Runtime	Expo
Language	TypeScript
Styling	NativeWind, Tailwind CSS, class-variance-authority
Routing	React Navigation (static config, `src/routes` )
Server state	TanStack Query
Client global state	Zustand
HTTP	Axios
Dates	date-fns ( `src/libs/date-utils/` )
Presentational UI	React Native Reusables-style primitives in `src/ui/`

Setup

Item	Required	When	How
Standing rule	required	Scaffold new app	Add - `<target_path>` follows building-react-native-application; load it before changing code there. to root `AGENTS.md` (create when missing) and to root `CLAUDE.md` when it exists without importing `AGENTS.md` ; skip a file that has it

Agent workflow

Follow this skill for Expo/React Native work. Resolve every required Setup row, then match Entry points and every applicable Task types row; open every linked local reference before coding. For component work, open creating-component and follow its decision tree. Platform docs live in each reference’s References section.

Entry points

Use the first matching row; combine when the task spans types.

Entry	When	Go to
Component	Building, moving, or recategorizing any component	creating-component
Structure	Folder roles, dependency flow, or where a module belongs	managing-project-structure
Task bundle	API, forms, styling, bootstrap, navigation, keyboard, fonts, splash	Task types table
Lookup	Known doc name or single reference	Reference index

Task types

Match every row that applies. Open every local link in Docs before coding.

Task type	Docs
New screen / feature	managing-project-structure, creating-feature, creating-route-component, creating-screen-component, creating-component
UI primitive ( `src/ui/` )	creating-component, creating-ui-component, discovering-registry-components, managing-wrapper-components, add-registry-component.cjs
Feature component	creating-component, creating-feature-component, managing-wrapper-components
Bottom sheet	creating-component, creating-bottom-sheet-component, managing-wrapper-components
Async / list UI	creating-component, creating-async-component, creating-api, managing-state
Form (single step)	creating-form-component, managing-form-error, managing-state, managing-date
Multi-step form	managing-stepper-hook, managing-stepper-form, creating-form-component, managing-form-error
API + data hooks	creating-api, setting-up-axios, managing-api-error, managing-state, managing-date
Date / time	managing-date
Refactor / move component	creating-component
Styling / theme	setting-up-nativewind, managing-styling, setting-up-theming, setting-up-tailwind-theme, setting-up-navigation-theme, overriding-classname
Navigation components & backgrounds	creating-navigation-component, setting-up-navigation-theme, managing-screen-background
Navigation hooks	creating-route-component, creating-navigation-component
Keyboard	Keyboard controller — Components
Fonts	setting-up-theming, setting-up-tailwind-theme, Expo — Fonts
Splash screen	Expo — SplashScreen
Scaffold new app	scaffolding-application
Project bootstrap	managing-project-structure, managing-environment, managing-linting, managing-package-installs, setting-up-nativewind, setting-up-registry-components
Routing only	creating-route-component, creating-navigation-component
