#🚀 Quick Start (5 Minutes)

#1. Create GitHub Token

# Visit: https://github.com/settings/tokens
# Generate new token with 'repo' scope
# Copy the token immediately

#2. Configure Environment

# Create .env file in project root
echo "GITHUB_TOKEN=ghp_your_actual_token_here" > .env

#3. Test Setup

# Verify GitHub API connection
npm run test:releases

#4. Run Locally

# Start development server
npm run dev

# Visit in browser
open http://localhost:4321/download

#5. Upload Release

# Go to: https://github.com/setoelkahfi/pepakbasajawa/releases
# Create new release with files named like:
# - pepakbasajawa-1.0.0-macos-arm64.dmg
# - pepakbasajawa-1.0.0-windows-x64.exe
# - pepakbasajawa-1.0.0-linux-x64.AppImage

#📝 File Naming Convention

Pattern: {app}-{version}-{platform}-{arch}.{ext}

Examples: ```bash ✅ pepakbasajawa-1.0.0-macos-arm64.dmg ✅ pepakbasajawa-1.0.0-macos-x64.dmg ✅ pepakbasajawa-1.0.0-windows-x64.exe ✅ pepakbasajawa-1.0.0-linux-x64.AppImage ✅ pepakbasajawa-1.0.0-linux-x64.deb

❌ app.dmg # Too generic ❌ release-v1.exe # No platform info ❌ my-app-latest.AppImage # No version ```

#🧪 Testing

#Test GitHub Connection

npm run test:releases

Expected output: ``` 🔍 Testing GitHub API Connection

✓ GitHub token found ✓ Authenticated as: setoelkahfi ✓ Found release: Release 1.0.0

📋 Release Assets: 🍎 pepakbasajawa-1.0.0-macos-arm64.dmg Platform: macOS (Apple Silicon) Size: 120.00 MB

✅ All tests passed! ```

#Test API Endpoint

# Start server
npm run dev

# Test in another terminal
curl http://localhost:4321/api/download-desktop-app | jq

#Test in Browser

open http://localhost:4321/download

#🚀 Deployment

#Vercel

vercel env add GITHUB_TOKEN
# Paste token when prompted
vercel --prod

#Netlify

netlify env:set GITHUB_TOKEN your_token_here
netlify deploy --prod

#Other Platforms

Add GITHUB_TOKEN environment variable in your hosting dashboard.

#⚠️ Common Issues & Solutions

#"GITHUB_TOKEN is not configured"

# Check .env file exists
cat .env | grep GITHUB_TOKEN

# Restart dev server
npm run dev

#"Failed to fetch releases"

# Verify token permissions
# Token needs 'repo' scope for private repos

# Test manually
curl -H "Authorization: Bearer $GITHUB_TOKEN" \
  https://api.github.com/repos/setoelkahfi/pepakbasajawa/releases/latest

#No downloads showing

# Run diagnostic
npm run test:releases

# Check:
# 1. Release exists and is "latest"
# 2. Release has uploaded assets
# 3. Asset filenames match patterns
