Perfect for analyzing Language Server Protocol (LSP) logs, debugging API communications, and understanding request-response flows.\n\n## 🚀 How to Use\n\n### 1. **Input Your Data**\nPaste your JSON-RPC communication logs into the textarea. The tool accepts:\n- Raw JSON Lines (one JSON object per line)\n- Messages with Content-Length headers (LSP format)\n- Mixed formats with varying whitespace\n\n### 2. **Parse & Visualize**\nClick **\"Parse Messages\"** to extract and display the JSON-RPC messages with:\n- **Request-Response Grouping**: Related messages are paired together\n- **Direction Indicators**: Client → Server vs Server → Client\n- **Message Types**: REQUEST, RESPONSE, NOTIFICATION\n- **Method Names & IDs**: Clearly labeled for easy identification\n\n### 3. **Control Your View**\nUse the toolbar buttons to customize the display:\n- **Toggle Grouping**: Switch between grouped pairs and chronological order\n- **Hide Ping**: Filter out noisy ping/keepalive messages\n- **Collapse/Expand All**: Minimize or maximize all message content\n- **Individual Controls**: Collapse/expand specific messages or pairs\n\n## 📋 Example Input Format\n\n```\nContent-Length: 87\n\n{\"jsonrpc\":\"2.0\",\"id\":1,\"method\":\"initialize\",\"params\":{\"capabilities\":{}}}\nContent-Length: 45\n\n{\"jsonrpc\":\"2.0\",\"id\":1,\"result\":{\"capabilities\":{}}}\nContent-Length: 52\n\n{\"jsonrpc\":\"2.0\",\"method\":\"initialized\",\"params\":{}}\n```\n\n## ✨ Key Features\n\n- **Smart Grouping**: Automatically pairs requests with their responses\n- **Ping Filtering**: Hide noisy keepalive messages with one click\n- **Visual Distinction**: Color-coded messages with clear direction indicators\n- **Flexible Views**: Toggle between grouped and chronological display\n- **Newest First**: Messages displayed in reverse chronological order\n- **Responsive Design**: Works on desktop and mobile devices\n- **Privacy-First**: All parsing happens client-side, no data sent to servers\n\n## 🏗️ Architecture\n\nThe application is organized into a clean, modular structure:\n\n```\n├── main.ts # Hono backend entry point\n├── frontend/ # Client-side application\n│ ├── index.html # Main HTML template\n│ ├── style.css # Custom styles\n│ ├── app.js # Application initialization\n│ └── README.md\n├── shared/ # Shared components\n│ ├── JsonRpcViewer.js # Main application

utilities\n│ └── README.md\n└── README.md\n```\n\n### Component Responsibilities\n\n- **Backend (Hono)**: Static file serving and API endpoints\n- **Frontend**: User interface and interaction handling\n- **Shared**: Core business logic that works in both environments\n\n## 🎯 Perfect For\n\n- **LSP Analysis**: Debug Language Server Protocol communications\n- **API Development**: Visualize JSON-RPC API request/response flows\n- **Protocol Debugging**: Understand complex message sequences\n- **Documentation**: Create visual representations of API interactions\n- **Learning**: Study how JSON-RPC protocols work in practice\n\n## 🔧 Technical Notes\n\n- Built with Hono backend and vanilla JavaScript frontend\n- ES6 modules with no build step required\n- TailwindCSS for responsive styling\n- Handles malformed JSON gracefully with error reporting\n- Supports large message logs with efficient parsing\n- No external dependencies or data transmission",[143],"2110bfb4-471c-11f0-977c-76b3cceeab13","shared","d8a55064-8c2e-4aab-82c9-82fc4ceb3c57",32,["D",1749684658781],"directory",[151],"0b869b3c-471c-11f0-b65e-76b3cceeab13","frontend","8e813ccc-9e6b-4569-88d0-73193adcbc13",29,["D",1749684622636],[158],"pulls","branches","forks","envVars",{"_170":63,"_172":63},"connections",{"_170":63,"_171":63},"count","unfilledCount","emptyCount",{"_44":157,"_32":158,"_30":159,"_133":-5,"_42":43,"_41":160,"_135":59,"_39":272,"_13":63,"_34":155,"_36":-5,"_24":25,"_140":-5,"_188":273,"_27":274},{"_44":265,"_32":143,"_30":266,"_133":159,"_42":43,"_41":267,"_135":59,"_39":268,"_13":63,"_34":20,"_36":269,"_24":25,"_140":-5,"_188":270,"_27":271},{"_44":257,"_32":258,"_30":259,"_133":159,"_42":43,"_41":260,"_135":59,"_39":261,"_13":63,"_34":35,"_36":262,"_24":25,"_140":-5,"_188":263,"_27":264},{"_44":249,"_32":250,"_30":251,"_133":159,"_42":43,"_41":252,"_135":59,"_39":253,"_13":147,"_34":20,"_36":254,"_24":25,"_140":-5,"_188":255,"_27":256},{"_44":241,"_32":242,"_30":243,"_133":159,"_42":43,"_41":244,"_135":25,"_39":245,"_13":137,"_34":20,"_36":246,"_24":25,"_140":-5,"_188":247,"_27":248},{"_44":150,"_32":151,"_30":152,"_133":-5,"_42":43,"_41":153,"_135":59,"_39":238,"_13":63,"_34":155,"_36":-5,"_24":25,"_140":-5,"_188":239,"_27":240},{"_44":233,"_32":33,"_30":31,"_133":152,"_42":43,"_41":14,"_135":59,"_39":234,"_13":235,"_34":35,"_36":38,"_24":25,"_140":-5,"_188":236,"_27":237},{"_44":225,"_32":226,"_30":227,"_133":152,"_42":43,"_41":228,"_135":59,"_39":229,"_13":137,"_34":35,"_36":230,"_24":25,"_140":-5,"_188":231,"_27":232},{"_44":217,"_32":218,"_30":219,"_133":152,"_42":43,"_41":220,"_135":59,"_39":221,"_13":63,"_34":35,"_36":222,"_24":25,"_140":-5,"_188":223,"_27":224},{"_44":209,"_32":210,"_30":211,"_133":152,"_42":43,"_41":212,"_135":25,"_39":213,"_13":137,"_34":35,"_36":214,"_24":25,"_140":-5,"_188":215,"_27":216},{"_44":202,"_32":143,"_30":203,"_133":152,"_42":43,"_41":204,"_135":59,"_39":205,"_13":63,"_34":20,"_36":206,"_24":25,"_140":-5,"_188":207,"_27":208},{"_44":194,"_32":195,"_30":196,"_133":152,"_42":43,"_41":197,"_135":59,"_39":198,"_13":63,"_34":35,"_36":199,"_24":25,"_140":-5,"_188":200,"_27":201},{"_44":142,"_32":143,"_30":144,"_133":-5,"_42":43,"_41":145,"_135":59,"_39":191,"_13":147,"_34":20,"_36":148,"_24":25,"_140":-5,"_188":192,"_27":193},{"_44":131,"_32":132,"_30":57,"_133":-5,"_42":43,"_41":134,"_135":59,"_39":187,"_13":137,"_34":138,"_36":139,"_24":25,"_140":-5,"_188":189,"_27":190},["D",1749684760695],"children",[],[132],["D",1749684792058],[],[143],"503a8b26-471c-11f0-bcea-76b3cceeab13","utils.js","503a8cac-471c-11f0-bcea-76b3cceeab13",36,["D",1749684737908],"/**\n
