Contributing

Thanks for contributing! 😁 Here are some rules that will make your example last as long as possible in the constantly changing React ecosystem.

Rules

• It's important to keep examples concise.
  • Start with the blank example.
  • We use a unified .gitignore
  • No package.json or app.config.js values that aren't completely necessary
    • Avoid scripts as these get added by create-react-native-app.
  • Use the new app.config.js instead of app.json
  • Do not include an app.config.js unless it has values that are relevant to the example
  • Use remote files for the default assets in the app.config.js:
    • expo.icon -- "https://github.com/expo/expo/blob/master/templates/expo-template-blank/assets/icon.png?raw=true"
    • expo.splash.image -- "https://github.com/expo/expo/blob/master/templates/expo-template-blank/assets/splash.png?raw=true"
  • Don't use the "sdkVersion" field in your app.config.js, this should be inferred from the installed version of expo in the package.json.
  • If your example README.md requires assets like images, place them in a hidden .gh-assets folder, ex: with-your-example/.gh-assets.
  • Limit package versions to patches only in the package.json:

  + "expo-three": "~1.0.0"
  
  - "expo-three": "^1.0.0"

• Each example can be used as a template in create-react-native-app so try to consider what a fresh template should look like:
  • No TODO, NOTE(), or otherwise.
  • No personal references to your name or other contextual info in comments.

Format

Every example needs a README.md that explains how to setup, the motivation behind the example, and what platforms it supports.

## 🚀 How to use

<!-- Setup instructions -->

## 📝 Notes

<!-- Link to related Expo or library docs -->

Add a File Structure section (between "How to use" and "Notes") if the example reflects a custom workflow:

### 📁 File Structure

\```
Expo Gatsby
├── src
│   └── pages ➡️ Routes
│       └── index.tsx ➡️ Entry Point for Gatsby
├── .cache ➡️ Generated Gatsby files (should be ignored)
├── public ➡️ Generated Gatsby files (should be ignored)
├── assets ➡️ All static assets for your project
├── App.tsx ➡️ Entry Point for Mobile apps
├── app.config.js ➡️ Expo config file
├── gatsby-config.js ➡️ Gatsby config file
└── babel.config.js ➡️ Babel config (should be using `babel-preset-expo`)
\```
