## 🔧 Development & Publishing Guide

### For Library Developers

If you're working on this component library and need to make changes, follow these steps:

#### 1. Setup Development Environment

```bash
# Clone the repository
git clone https://github.com/Nestbotics/nct_frontend_common_components.git
cd nct_frontend_common_components

# Install dependencies
npm install
```

#### 2. Development Workflow

```bash
# Start development build (watches for changes)
npm run dev

# Or manually build for testing
npm run build
```

#### 3. Making Changes

When you modify components in the `src/` folder:

- **Components**: Edit files in `src/components/common/`
- **Themes**: Modify `src/theme/Theme.js`, `src/theme/dark_theme.js`, or `src/theme/light_theme.js`
- **Context**: Update `src/context/UserDataProvider.jsx` or `src/context/user_data/StyleProvider.jsx`
- **Styles**: Edit `src/assets/styles/global.css`
- **Exports**: Update `src/index.js` to expose new components

#### 4. Testing Changes Locally

```bash
# Build the package
npm run build

# Create a local package for testing
npm pack

# This creates a .tgz file that you can install in other projects:
# npm install /path/to/nestbotics-nct_frontend_common_components-1.0.4.tgz
```

#### 5. Version Management

```bash
# Update version (patch: 1.0.4 -> 1.0.5)
npm version patch

# Update version (minor: 1.0.4 -> 1.1.0)
npm version minor

# Update version (major: 1.0.4 -> 2.0.0)
npm version major
```

#### 6. Publishing Process

**Option A: Publish to NPM (Recommended)**

```bash
# Login to npm (one-time setup)
npm login

# Publish to npm
npm publish
```

**Option B: Publish to GitHub Packages**

```bash
# Login to GitHub packages (one-time setup)
npm login --registry=https://npm.pkg.github.com/

# Publish to GitHub packages
npm publish --registry=https://npm.pkg.github.com/
```

#### 7. Complete Release Workflow

```bash
# 1. Make your changes
git add .
git commit -m "feat: add new component or fix bug"

# 2. Update version
npm version patch  # or minor/major

# 3. Build the package
npm run build

# 4. Test the build
npm run test  # if you have tests

# 5. Publish
npm publish

# 6. Push changes and tags to GitHub
git push origin main --tags
```

#### 8. Build Process Details

The build process creates:

- **`dist/index.js`** - CommonJS version for older projects
- **`dist/index.esm.js`** - ES Modules version for modern projects
- **`dist/index.d.ts`** - TypeScript declarations
- **`dist/assets/`** - Styles, fonts, and images
- **`dist/components/`** - Compiled components

#### 9. What Gets Published

The `.npmignore` file ensures only these files are published:

- `dist/` folder (compiled code)
- `README.md`
- `LICENSE`
- `package.json`

The `src/` folder and development files are excluded from the published package.

#### 10. Troubleshooting

**Build fails?**
```bash
# Clean and rebuild
npm run clean
npm run build
```

**Import issues after changes?**
- Check that new components are exported in `src/index.js`
- Ensure proper default exports in component files
- Verify TypeScript declarations are updated

**Publish fails?**
- Check if you're logged in: `npm whoami`
- Verify version hasn't been published: check npm registry
- Ensure you have publish rights to the package

## 🔧 Troubleshooting

### Toast Functionality Error: `S.keyframes is not a function`

If you encounter this error, it's due to a styled-components conflict with react-hot-toast. Follow these steps:

1. **Install required dependencies:**
   ```bash
   npm install react-hot-toast react-toastify styled-components
   ```

2. **Add Toast Provider to your app:**
   ```jsx
   import { Toaster } from 'react-hot-toast';

   function App() {
     return (
       <div>
         {/* Your app content */}
         <Toaster
           position="top-right"
           toastOptions={{
             duration: 4000,
             style: {
               background: '#363636',
               color: '#fff',
             },
           }}
         />
       </div>
     );
   }
   ```

3. **Alternative: Use without toast libraries**
   The components work without toast libraries - toast calls will fallback to console logging.

For detailed troubleshooting, see [TOAST_TROUBLESHOOTING.md](./TOAST_TROUBLESHOOTING.md).

### Common Issues

- **Missing peer dependencies**: Run `npm ls` to check for missing peer dependencies
- **Version conflicts**: Ensure React version >= 16.8.0
- **Theme not loading**: Make sure to wrap your app with the theme provider
