## What it does

The skill splits into 10 categories by priority: project setup, routing, screens, data fetching, auth, deep linking, native UX, forms, assets and testing. Each rule carries a prefix (`setup-`, `route-`, `screen-`, `data-`, `auth-`, `link-`, `ux-`, `form-`, `asset-`, `test-`) and lives in its own file under `references/`. The agent pulls the file it needs when a task touches that area.

Templates sit in `assets/templates/`: a bottom tab layout with icons, a root layout with protected routes, and a list screen built on FlashList with refresh and loading states. Navigation covers tabs, stacks, drawers and modals through Expo Router, plus dynamic segments `[param]` and typed routes. Auth uses a session context, OAuth with AuthSession and `Stack.Protected` guards.

The rules assume a TypeScript project: strict mode, a typed `app.config.ts`, environment variables with the `EXPO_PUBLIC_` prefix. On a plain JavaScript codebase you will have to adapt part of them by hand. Build setup covers EAS profiles and development builds instead of Expo Go.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add pproenca/dot-skills --skill expo-react-native-coder -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/expo-react-native-coder/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/expo-react-native-coder/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add pproenca/dot-skills --skill expo-react-native-coder -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/expo-react-native-coder/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add pproenca/dot-skills --skill expo-react-native-coder -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/expo-react-native-coder/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install pproenca/dot-skills expo-react-native-coder
```

2. **Manually: put the files in place**
- File: `.github/skills/expo-react-native-coder/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add pproenca/dot-skills --skill expo-react-native-coder -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/pproenca/dot-skills --path skills/.experimental/expo-react-native-coder
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/expo-react-native-coder/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add pproenca/dot-skills --skill expo-react-native-coder -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/pproenca/dot-skills/tree/HEAD/skills/.experimental/expo-react-native-coder/SKILL.md

## When to use it
- scaffold a new Expo project in TypeScript
- wire up tabs, stacks and modal screens
- guard screens behind authentication
- set up deep links and universal links
- test components with Jest and Maestro

## Example prompts
- Build an orders list screen with FlashList and pull-to-refresh
- Set up protected routes so signed-out users land on the login screen
- Handle an incoming link that opens the product detail screen

# Expo React Native Coder Best Practices

Comprehensive feature development guide for Expo React Native applications. Contains 50 rules across 10 categories, covering everything from project setup to testing. Includes production-ready code templates for common features.

## When to Apply

Reference these guidelines when:
- Setting up a new Expo project with TypeScript
- Building navigation with Expo Router (tabs, stacks, drawers, modals)
- Creating screens (list, detail, form, settings)
- Implementing authentication flows with protected routes
- Configuring deep linking and universal links

## Rule Categories by Priority

| Priority | Category | Impact | Prefix |
|----------|----------|--------|--------|
| 1 | Project Setup & Configuration | CRITICAL | `setup-` |
| 2 | Routing & Navigation | CRITICAL | `route-` |
| 3 | Screen Patterns & Layouts | HIGH | `screen-` |
| 4 | Data Fetching & State | HIGH | `data-` |
| 5 | Authentication & Security | HIGH | `auth-` |
| 6 | Deep Linking & Universal Links | HIGH | `link-` |
| 7 | Native UX Patterns | MEDIUM-HIGH | `ux-` |
| 8 | Forms & User Input | MEDIUM | `form-` |
| 9 | Assets & Theming | MEDIUM | `asset-` |
| 10 | Error Handling & Testing | MEDIUM | `test-` |

## Quick Reference

### 1. Project Setup & Configuration (CRITICAL)

- [`setup-typescript-config`](references/setup-typescript-config.md) - Configure TypeScript with strict mode
- [`setup-app-config-typescript`](references/setup-app-config-typescript.md) - Use typed app.config.ts
- [`setup-environment-variables`](references/setup-environment-variables.md) - EXPO_PUBLIC_ prefix for client vars
- [`setup-eas-build-profiles`](references/setup-eas-build-profiles.md) - EAS build profiles per environment
- [`setup-development-build`](references/setup-development-build.md) - Development builds vs Expo Go

### 2. Routing & Navigation (CRITICAL)

- [`route-file-based-routing`](references/route-file-based-routing.md) - File-based routing with Expo Router
- [`route-tab-navigator`](references/route-tab-navigator.md) - Tab navigator with route groups
- [`route-dynamic-segments`](references/route-dynamic-segments.md) - Dynamic route segments [param]
```
