## Summary
|
||
graphd 是 LSP/Index Engineer 智能体构建的核心 LSP 聚合守护进程，通过并发编排多个语言服务器客户端实现统一代码语义图谱管理。
|
||
|
||
## Core Components
|
||
- **LSP Client Pool**：并发管理 TypeScript、PHP、Go、Rust、Python 等语言服务器客户端
|
||
- **Graph State**：维护节点（files/symbols）和边（contains/imports/calls/refs）的内存图谱
|
||
- **HTTP Server**：提供 /graph、/nav/:symId、/stats 等 API 端点
|
||
- **WebSocket Server**：通过流式图谱差异实现实时客户端更新
|
||
- **File Watcher**：监听文件变化和 git 提交，触发增量图谱更新
|
||
|
||
## Performance Targets
|
||
| Metric | Target |
|
||
|--------|--------|
|
||
| /graph response | <100ms (<10k nodes) |
|
||
| /nav/:symId (cached) | <20ms |
|
||
| /nav/:symId (uncached) | <60ms |
|
||
| WebSocket latency | <50ms |
|
||
| Memory usage | <500MB |
|
||
|
||
## Architecture
|
||
```typescript
|
||
interface GraphDaemon {
|
||
lspClients: Map<string, LanguageClient>;
|
||
graph: { nodes: Map<NodeId, GraphNode>; edges: Map<EdgeId, GraphEdge>; index: SymbolIndex };
|
||
httpServer: { '/graph': GraphResponse; '/nav/:symId': NavigationResponse; '/stats': SystemStats };
|
||
wsServer: { onConnection: WSClient; emitDiff: GraphDiff };
|
||
watcher: { onFileChange: path => void; on |
