一個強調「模組化設計」、「明確協定定義」、「靈活組裝」與「易於擴展」的 LLM 應用開發框架。
核心理念為：所有功能皆以 Brick 組件為單元，協定明確、組裝彈性，方便擴充與客製化。

## 特色

- 🧱 **模組化設計**：所有功能皆以 Brick 為單元，組件可插拔、可重組，支援多層次組裝。
- 📑 **明確協定定義**：所有 Brick 之間的資料流、型別、錯誤皆有明確協定（protocols/ 目錄），便於跨語言、跨協議整合。
- 🔄 **多協議支援**：SSE、gRPC（WebSocket/WebRTC 計畫中），可依需求切換。
- 🔧 **易於擴展**：插件系統與自定義組件，支援靈活擴充與客製化。

### 設計理念

- **模組化**：每個 Brick 可獨立開發、測試、組裝，降低耦合。
- **協定導向**：所有資料流、型別、錯誤皆有明確協定，便於跨語言、跨協議整合。
- **靈活組裝**：Pipeline、Server、Client 皆可自由組合各種 Brick，支援多種應用場景。
- **易於擴展**：可自訂新 Brick、協定或插件，快速擴充功能。

## 快速開始

### 安裝

```bash
pip install llmbrick
```

### 基本使用

```python
from llmbrick import OpenAILLM
from llmbrick.servers.sse import SSEServer

# 建立 LLM Brick
llm_brick = OpenAILLM(api_key="your-api-key")

# 啟動 SSE 服務
server = SSEServer(llm_brick)
server.run(host="0.0.0.0", port=8000)
```

## 測試頁面

SSEServer 提供了內建的測試頁面，方便開發和測試：

```python
# 啟用測試頁面
server = SSEServer(enable_test_page=True)
server.run(host="0.0.0.0", port=8000)
```

測試頁面特色：
- 完整的請求表單，支援所有 SSERequest 欄位
- 動態訊息管理（新增/刪除/重排序）
- 即時串流輸出顯示，支援自動捲動
- 不同類型訊息顏色區分
- 時間戳記標記
- 深色/淺色主題切換
- 完整的 API 文件和範例

## Metrics Utilities

The `llmbrick.utils.metrics` module provides decorators for monitoring function performance and resource usage. All decorators support both sync and async functions.

### Available Decorators

- **@measure_time**  
  Logs the execution time of the decorated function.

- **@measure_memory**  
  Logs the difference in process memory usage (RSS, MB) before and after the function runs. Requires `psutil`.

- **@measure_peak_memory**  
  Logs the peak memory usage (MB) during function execution using `tracemalloc`.

### Usage Example

```python
from llmbrick.utils.metrics import measure_time, measure_memory, measure_peak_memory

@measure_time
def sync_func(x):
    return x * 2

@measure_memory
async def async_func(x):
    a = [0] * 10000
    return x + 1

@measure_peak_memory
def another_sync_func(x):
    a = [0] * 10000
    return x - 1
```

All decorators will log performance metrics using the standard logging module.  
For async functions, simply decorate as usual.
