# build-your-own-koa

koa核心2点： 1. 中间件模式  2. 洋葱模型

## 中间件模式

中间件ctx实现核心：

``` js

createContext(req, res) {

    let ctx = this.context

    // 原生req/res

    ctx.req = req // ctx.req.url

    ctx.res = res

    ctx.request = this.request // ctx.request.url

    ctx.response = this.response

    ctx.request.req = req // ctx.request.req.url

    ctx.response.res = res

    return ctx

}

```

## 洋葱模型
