Built for Val Town with TypeScript, React, and Hono.\n\n## Features\n\n- **Web Serial API Integration**: Flash firmware directly from the browser\n- **Multiple Device Support**: ESP32, ESP8266, and CYD (Cheap Yellow Display) variants\n- **Pre-built Payloads**: Bruce, ESP32 Marauder, Ghost ESP, Netagotchi\n- **ELF to BIN Conversion**: Upload ELF files and convert them to flashable binaries\n- **Device Information**: Read MAC address, chip features, and flash info\n- **Secure**: Input validation, rate limiting, and CORS protection\n\n## Project Structure\n\n```\n├── backend/\n│ ├── index.ts # Main Hono server\n│ ├── routes/\n│ │ ├── firmware.ts # Firmware management endpoints\n│ │ ├── serial.ts # Serial/flashing endpoints\n│ │ └── static.ts # Static file serving\n│ ├── services/\n│ │ ├── firmwareStore.ts # Firmware storage and management\n│ │ └── elfConverter.ts # ELF to BIN conversion\n│ └── utils/\n│ └── validation.ts # Input validation and security\n├── frontend/\n│ ├── index.html # Main HTML template\n│ ├── index.tsx # React app entry point\n│ ├── components/\n│ │ ├── App.tsx # Main app component\n│ │ ├── ConnectPort.tsx # Serial port connection\n│ │ ├── FlashControls.tsx # Flashing interface\n│ │ └── FirmwareList.tsx # Available firmware list\n│ └── services/\n│ ├── serialService.ts # Web Serial API wrapper\n│ └── api.ts # Backend API client\n├── shared/\n│ └── types.ts # Shared TypeScript types\n└── firmwares/ # Pre-built firmware binaries\n ├── bruce/\n ├── marauder/\n ├── ghost-esp/\n └── netagotchi/\n```\n\n## Getting Started\n\n1. The main entry point is `backend/index.ts` (HTTP trigger)\n2. Frontend is served from `/` and API endpoints are under `/api/`\n3. Firmware files are stored in the `firmwares/` directory\n4. Web Serial API requires HTTPS in production\n\n## API Endpoints\n\n- `GET /api/firmwares` - List available firmware\n- `GET /api/firmwares/:name` - Download firmware binary\n- `POST /api/convert` - Convert ELF to BIN\n- `GET /api/device-info` - Get supported device information\n\n## Browser Compatibility\n\n- Chrome/Edge 89+\n- Opera 75+\n- Web Serial API required (HTTPS only in production)\n\n## Security Features\n\n- Input validation on all uploads\n- Rate limiting on conversion endpoints\n- CORS protection\n- File size limits\n- Malicious content scanning\n\n## Development\n\nThe app automatically serves the frontend and handles API requests. All firmware binaries are pre-loaded and ready for flashing.",[],[331],{"_104":338,"_96":339,"_159":340,"_161":-5,"_162":140,"_163":139,"_164":165,"_106":341,"_101":32,"_167":185,"_169":73,"_170":22,"_171":-5,"_172":342,"_99":343},"73f626ba-eb72-11f0-a608-42dde27851f2","main.tsx","019b9655-354a-70d0-8bc9-7d033a5445bf",["D",1767753725210],[],[339],{"_104":345,"_96":346,"_159":347,"_161":-5,"_162":140,"_163":139,"_164":165,"_106":348,"_101":32,"_167":185,"_169":73,"_170":22,"_171":-5,"_172":349,"_99":350},"73f62c14-eb72-11f0-a608-42dde27851f2","new-file-4841.tsx","019b9655-354a-70d0-8bc9-81c609155c0e",["D",1767753725210],[],[346],"files",[156,174,180,189,197,206,212,220,229,235,244,253,259,265,274,279,287,296,305,314,320,329,337,344],"counts",{"_355":32,"_356":139,"_357":32,"_358":359},"pulls","branches","forks","envVars",{"_360":32,"_361":32},"count","emptyCount","contents",[],{"_104":190,"_96":191,"_159":192,"_161":177,"_162":140,"_163":139,"_164":165,"_106":365,"_101":32,"_167":185,"_169":194,"_170":22,"_171":-5,"_99":366},["D",1767753725210],[158,176,191],"upstreamProject",{"_104":148,"_96":97,"_112":113,"_114":-5,"_110":111,"_23":369},{"_94":370,"_132":371},"canstralian","https://img.clerk.com/eyJ0eXBlIjoicHJveHkiLCJzcmMiOiJodHRwczovL2ltYWdlcy5jbGVyay5kZXYvdXBsb2FkZWQvaW1nXzJ5dncxVUwwR0NJUlhncHZ1a2NHMXZxS1g5ZSJ9","upstreamBranch",{"_104":143,"_106":374,"_375":376,"_96":44,"_141":148,"_101":145,"_142":-5,"_144":-5,"_377":-5,"_108":-5,"_153":22,"_110":111,"_152":370,"_16":150,"_151":97},["D",1751611400518],"updatedAt",["D",1751611898110],"lockfileKey","emptyEnvVars","isNew","flags",[],"routes/_app.x.$handle.$name.branch.$branch.history_.$",{"_94":95,"_96":97,"_98":44,"_99":100,"_102":384,"_301":389,"_392":393,"_396":397,"_400":-7,"_401":32,"_402":22},{"_104":105,"_96":97,"_106":385,"_108":-5,"_109":22,"_110":111,"_112":113,"_114":-5,"_14":115,"_116":-5,"_117":22,"_118":-5,"_119":-5,"_120":32,"_16":121,"_122":123,"_124":123,"_125":126,"_127":126,"_128":126,"_129":123,"_130":123,"_23":386,"_134":387,"_137":388,"_153":22},["D",1767753725210],{"_94":95,"_132":133},{"_94":95,"_136":133,"_14":115},{"_101":139,"_96":44,"_104":140,"_141":105,"_142":143,"_144":145,"_146":111,"_147":148,"_149":150,"_151":97,"_152":95},{"_104":190,"_96":191,"_159":192,"_161":177,"_162":140,"_163":139,"_164":165,"_106":390,"_101":32,"_167":185,"_169":194,"_170":22,"_171":-5,"_99":391},["D",1767753725210],[158,176,191],"history",[394],{"_104":190,"_162":140,"_159":192,"_96":191,"_169":194,"_167":185,"_101":32,"_161":177,"_106":395,"_163":139,"_171":-5},["D",1767753725210],"versions",[398],{"_301":394,"_399":-5},"previous","versionNumber","page","hasNext","actionData","errors"]
