Akt 是一个个人学习用的简易的 web 框架，其设计理念是来源自于 Gin 。
Akt 拥有 golang 和 nodejs 两种版本，其中 nodejs 中还拥有 class 和 func 两个版本。

yarn dev- 支持 get, post 请求
- 提供对 JSON、HTML 等返回类型的支持
- 支持 query 和 param 传参
- 支持
:name和*filepath的路由前缀 - 支持路由分组
- 支持中间件
- 拥有 HTML 模板渲染及静态资源服务
- 拥有错误恢复机制

}使用实例位于app.ts中
import akt, { AktContext } from "./classVersion";
// import akt, { AktContext } from "./funcVersion";
const app = akt();
// 添加get
app.get("/", (ctx: AktContext) => {

// 支持static
app.static("/assets", "./assets/");
// 设置模板所在文件夹
app.loadHTMLGlob("./assets");
// 支持pug模板编译
app.get("/template", (ctx) => {
