1. `test` - Runs tests across multiple operating systems
2. `build` - Builds JVM and WASM artifacts
3. `code-quality` - Runs static code analysis
4. `security-scan` - Performs security vulnerability scanning
5. `dependency-check` - Checks for vulnerable dependencies
### 2. Release Automation (`release.yml`)
**Triggers:** Git tags (v*), Manual dispatch with version input
**Features:**
- **Semantic version validation** (v1.0.0 format)
- **Automated changelog generation** from git commits
- **Multi-format distribution packages** (tar.gz, zip)
- **GitHub release creation** with proper assets
- **Pre-release detection** for beta/alpha versions
- **Release notifications**
**Jobs:**
1. `validate-release` - Validates version format and extracts version info

3. `generate-changelog` - Generates changelog from git history
4. `create-release` - Creates GitHub release with artifacts
5. `notify-release` - Sends success notifications
### 3. Documentation (`docs.yml`)
**Triggers:** Push to main (docs changes), Pull requests, Manual dispatch
**Features:**
- **API documentation generation** using Dokka
- **GitHub Pages deployment** with custom landing page
- **Link validation** for documentation quality
- **Accessibility checks** for generated documentation
- **Automatic Dokka plugin integration**
**Jobs:**

2. `memory-analysis` - Analyzes memory usage during builds
3. `size-analysis` - Tracks artifact sizes and provides optimization recommendations
## 🔧 Configuration Details
### Dependabot Configuration
The `dependabot.yml` file configures automated dependency updates:
- **Gradle dependencies**: Weekly updates on Monday at 2:00 AM UTC
- **GitHub Actions**: Weekly updates on Monday at 2:30 AM UTC
- **Intelligent grouping**: Kotlin-related updates are grouped together
- **Version constraints**: Major Kotlin updates are ignored for stability
- **Proper labeling**: All PRs are labeled appropriately for easy identification
### Environment Variables and Secrets
The workflows use the following environment variables and secrets:
| Variable/Secret | Usage | Required |
|----------------|-------|----------|
| `GITHUB_TOKEN` | GitHub API access for releases and comments | ✅ Auto-provided |
| `GRADLE_OPTS` | Gradle optimization settings | ✅ Set in workflows |
### Performance Thresholds
The performance monitoring workflow uses these thresholds:
| Metric | Threshold | Status |
|--------|-----------|--------|
| Clean Build | < 2 minutes (120s) | Good / Slow |
| Incremental Build | < 30 seconds | Good / Slow |
| Test Execution | < 1 minute (60s) | Good / Slow |
| WASM Build | < 1.5 minutes (90s) | Good / Slow |
## 🎯 Best Practices Implemented

4. **Review Dependabot settings** and adjust reviewers/assignees
### First Run
1. **Push to main branch** to trigger CI/CD pipeline
2. **Create a tag** (e.g., `v1.0.0`) to test release automation
3. **Check GitHub Pages** deployment for documentation
4. **Review workflow runs** in the Actions tab
### Customization
To customize the workflows for your specific needs:
1. **Update reviewer/assignee** usernames in `dependabot.yml`
2. **Adjust performance thresholds** in `performance.yml`
3. **Modify build targets** in `ci.yml` if needed
4. **Update documentation URLs** in `docs.yml`
## 📊 Monitoring and Maintenance
### Regular Tasks
- **Review dependency update PRs** weekly
- **Monitor performance trends** in workflow artifacts
- **Update workflow versions** when new actions are available
- **Review security scan results** and address vulnerabilities
### Troubleshooting
Common issues and solutions:
1. **Build failures**: Check Gradle configuration and dependencies
2. **Documentation deployment**: Verify GitHub Pages settings
3. **Performance degradation**: Review performance reports and optimize
4. **Security alerts**: Address dependency vulnerabilities promptly

# OSM Maker - WebAssembly Demo
This project demonstrates a Kotlin application compiled to WebAssembly (WASM) that processes OpenStreetMap (OSM) data.
## Files
- `demo.html` - The main HTML demo file
- `build/dist/wasmJs/developmentExecutable/` - Contains the compiled WASM artifacts:
- `osm-maker.js` - JavaScript wrapper for the WASM module
- `db8d653255edcefb8149.wasm` - The WebAssembly binary
## How to Run the Demo
### Option 1: Using Python HTTP Server (Recommended)
1. Open a terminal in the project root directory
2. Start a local HTTP server:
```bash
python3 -m http.server 8080
```
Or if you have Python 2:
```bash
python -m SimpleHTTPServer 8080
```
3. Open your web browser and navigate to:
```
http://localhost:8080/demo.html
```
### Option 2: Using Node.js HTTP Server
1. Install a simple HTTP server globally:
```bash
npm install -g http-server
```
2. Run the server in the project directory:
```bash
http-server -p 8080
```
3. Open your browser to `http://localhost:8080/demo.html`
### Option 3: Using Live Server (VS Code Extension)
1. Install the "Live Server" extension in VS Code
2. Right-click on `demo.html` and select "Open with Live Server"
## What the Demo Does
The demo showcases a simplified version of OSM data processing:
1. **Location**: Processes data for Poquoson, Virginia (bounding box: 37.115,-76.396,37.139,-76.345)
2. **Functionality**:
- Parses geographic coordinates
- Calculates approximate area
- Demonstrates WASM compilation success
3. **Output**: Displays processing results in a browser-friendly interface
## Demo Features
- 🗺️ **Interactive Interface**: Clean, professional web interface
- 📍 **Geographic Processing**: Demonstrates coordinate parsing and calculations
- 🚀 **WASM Integration**: Shows successful Kotlin-to-WASM compilation
- 🖥️ **Console Output**: Captures and displays WASM output in the browser
- ⚡ **Real-time Feedback**: Status indicators and error handling
## Technical Details
- **Source**: Kotlin multiplatform project with WASM target
- **Build Tool**: Gradle with Kotlin multiplatform plugin
- **WASM Size**: ~543 KiB
- **JavaScript Wrapper**: ~57 KiB
- **Browser Compatibility**: Modern browsers with WASM support
## Troubleshooting
### CORS Issues
If you see CORS-related errors, make sure you're serving the files through an HTTP server rather than opening the HTML file directly in the browser.
### Module Loading Issues
If the WASM module fails to load:
1. Check that all files are in the correct locations
2. Ensure your browser supports WebAssembly
3. Check the browser console for detailed error messages
### No Output
If the demo runs but shows no output:
1. The main function might execute automatically during module initialization
2. Check the browser's developer console for any logged output
3. The fallback simulation should still demonstrate the expected functionality
## Building from Source
To rebuild the WASM artifacts:
```bash
./gradlew wasmJsBrowserDevelopmentExecutableDistribution
```
This will regenerate the files in `build/dist/wasmJs/developmentExecutable/`.
## Browser Support
The demo requires a modern browser with WebAssembly support:
- Chrome 57+
- Firefox 52+
- Safari 11+
- Edge 16+
## Next Steps
This demo provides a foundation for more complex WASM applications. Potential enhancements:
1. **Real OSM Data**: Integrate with Overpass API for live data
2. **3D Visualization**: Add WebGL rendering for 3D geometry
3. **Interactive Maps**: Integrate with mapping libraries like Leaflet
4. **Performance Metrics**: Add timing and memory usage statistics

<h3>About This Demo</h3>
<p>This demonstration showcases a Kotlin application compiled to WebAssembly (WASM) that processes OpenStreetMap (OSM) data. The original application converts OSM data to 3D geometry, but this WASM version provides a simplified demonstration of the core functionality.</p>
