## Thanks to [Koa](https://github.com/koajs/koa) and it's authors

## Demo

```js
const ilog = require('ilog')
const Toa = require('toa')

const app = new Toa()

app.use(function () {
this.body = 'support sync function middleware!\n'
})

app.use(function (next) {
this.body += 'support thunk function middleware!\n'
next()
})

app.use(function * () {
this.body += yield Promise.resolve('support generator function middleware!\n')
})
// support in Node.js v8
app.use(async function () {
this.body += await Promise.resolve('support async/await function middleware!\n')
})

app.listen(3000, () => ilog.info('App start at: 3000'))
```

## TypeScript Demo

```typescript
import { Toa } from 'toa'

const app = new Toa()

app.use(function () {
this.body = 'support sync function middleware!\n'
})

app.use(function (next) {
this.body += 'support thunk function middleware!\n'
next()
})

app.use(function * () {
this.body += yield Promise.resolve('support generator function middleware!\n')
})

app.use(async function () {
this.body += await Promise.resolve('support async/await function middleware!\n')
})

app.listen(3000, () => console.log('App start at 3000'))
```

## With HTTP/2

```js
// Visit: https://127.0.0.1:3000/
const http2 = require('http2')
const fs = require('fs')
const Toa = require('toa')
const server = http2.createSecureServer({
key: fs.readFileSync('./localhost.key'),
cert: fs.readFileSync('./localhost.crt')
})

const app = new Toa(server)
app.use(function () {
this.body = 'Hello World!\n-- toa'
})

app.listen(3000, () => console.log('https://127.0.0.1:3000/'))
```

## Install

```sh
npm install toa
```

## Toa 简介

**Toa** 是 **Koa** 的改进版。

**Toa** 修改自 **Koa**,基本架构原理与 **Koa** 相似,`context`、`request`、`response` 三大基础对象几乎一样。但 **Toa** 是基于 [thunks](https://github.com/thunks/thunks) 组合业务逻辑,来实现异步流程控制和异常处理。

**Toa** 的异步核心是 `thunk` 函数,支持 `node.js v0.10.x`,但在支持 generator 的 node 环境中(io.js, node.js >= v0.11.9)将会有更好地编程体验:**用同步逻辑编写非阻塞的异步程序**。

**Toa** 与 **Koa** 学习成本和编程体验是一致的,两者之间几乎是无缝切换。但 **Toa** 去掉了 **Koa** 的 `级联(Cascading)` 逻辑,强化中间件,强化模块化组件,尽量削弱第三方组件访问应用的能力,使得编写大型应用的结构逻辑更简洁明了,也更安全。

## 功能模块

与 Koa 一样, Toa 也没有绑定多余的功能,而仅仅提供了一个轻量优雅的函数库,异步控制处理器和强大的扩展能力。

使用者可以根据自己的需求选择独立的功能模块或中间件,或自己实现相关功能模块。以下是 Toajs 提供的基础性的功能模块。它们已能满足大多数的应用需求。
