117 ## Security Features
118
119 ### 1. Token Protection
120 - GitHub token never exposed to client
121 - Stored securely in environment variables
122 - Used only in server-side API routes
123
124 ### 2. Download Proxying
125 - Downloads go through API endpoint
126 - API authenticates with GitHub on user's behalf
127 - GitHub provides temporary redirect URLs
128 - Users don't need GitHub accounts
129
130 ### 3. Fine-Grained Permissions
131 - Token only needs `repo` scope (or just `Contents: Read`)
132 - No unnecessary permissions granted
133 - Can use fine-grained tokens for better security
134
135 ### 4. Rate Limiting
136 - 5-minute cache reduces API calls
137 - GitHub allows 5,000 authenticated requests/hour
138 - More than sufficient for production traffic
139
140 ## Platform Detection Logic
141
142 ### Detection Patterns
143
144 **macOS:**
145 - Keywords: `mac`, `darwin`
146 - Extensions: `.dmg`, `.pkg`
147 - Architectures:
148 - Apple Silicon: `arm64`, `aarch64`, `apple`
149 - Intel: `x64`, `x86_64`, `intel`
150 - Universal: `universal` or no architecture specified
151
152 **Windows:**
153 - Keywords: `win`, `windows`
154 - Extensions: `.exe`, `.msi`, `.msix`
155 - Architectures:
156 - x64: `x64`, `x86_64`, `amd64`
157 - ARM64: `arm64`, `aarch64`
158
159 **Linux:**
160 - Keywords: `linux`
161 - Extensions: `.appimage`, `.deb`, `.rpm`, `.tar.gz`, `.snap`
162 - Architectures:
163 - x64: `x64`, `x86_64`, `amd64`
164 - ARM64: `arm64`, `aarch64`
165
166 ### Recommended Naming Convention
167
168 ```
169 {app-name}-{version}-{platform}-{arch}.{ext}
170
171 Examples:
172 ✅ pepakbasajawa-1.0.0-macos-arm64.dmg
173 ✅ pepakbasajawa-1.0.0-macos-x64.dmg
174 ✅ pepakbasajawa-1.0.0-windows-x64.exe
175 ✅ pepakbasajawa-1.0.0-linux-x64.AppImage
176 ✅ pepakbasajawa-1.0.0-linux-x64.deb
177 ```
178
179 ## Setup Requirements
180
181 ### 1. Environment Variables
182
183 **Development (.env):**
184 ```env
185 GITHUB_TOKEN=ghp_your_token_here
186 ```
187
188 **Production:**
189 Set in hosting platform dashboard (Vercel, Netlify, etc.)
190
191 ### 2. GitHub Token
192
193 **Required Scopes:**
194 - Classic Token: `repo` scope
195 - Fine-Grained Token: `Contents: Read` + `Metadata: Read`
196
197 **Create Token:**
198 1. Go to https://github.com/settings/tokens
199 2. Generate new token
200 3. Select required scopes
201 4. Copy token immediately
202
203 ### 3. Release Assets
204
205 **Upload to GitHub:**
206 1. Create release tag (e.g., `v1.0.0`)
207 2. Upload built application files
208 3. Follow naming convention
209 4. Publish release
210
211 ## API Response Format

266 "details": "GitHub API error message"
267 }
268 ```
269
270 ## Testing Checklist
271
272 - [ ] Create `.env` file with `GITHUB_TOKEN`
273 - [ ] Run `npm run test:releases` to verify GitHub connection
274 - [ ] Create test release on GitHub with sample assets
275 - [ ] Start dev server: `npm run dev`
276 - [ ] Visit `http://localhost:4321/download`
277 - [ ] Verify all platforms are detected correctly
278 - [ ] Test downloading each asset type
279 - [ ] Check mobile responsiveness
280 - [ ] Verify error handling (remove token temporarily)
281 - [ ] Deploy to staging environment
282 - [ ] Test production environment
283 - [ ] Monitor API rate limits
284
285 ## Performance Considerations
286
287 ### Caching Strategy
288
289 **API Response Cache:**
290 - Duration: 5 minutes (300 seconds)
291 - Type: Public cache
292 - Header: `Cache-Control: public, max-age=300`
293
294 **Benefits:**
295 - Reduces GitHub API calls
296 - Faster page loads for subsequent visitors
297 - Stays within rate limits
298
299 **Trade-offs:**
300 - New releases take up to 5 minutes to appear
301 - Can be adjusted in API endpoint if needed
302
303 ### API Rate Limits
304
305 **GitHub API:**
306 - Authenticated: 5,000 requests/hour
307 - Unauthenticated: 60 requests/hour
308
309 **With 5-minute cache:**
310 - Max requests: 12 per hour per server
311 - Comfortable margin for high traffic
312
313 ## Deployment Guide
314
315 ### Vercel

317 ```bash
318 # Add environment variable
319 vercel env add GITHUB_TOKEN
320
321 # Deploy
322 vercel --prod
323 ```
324
325 ### Netlify
326
327 ```bash
328 # Via Netlify CLI
329 netlify env:set GITHUB_TOKEN your_token_here
