Async Store! 异步的 Store!

# from npm
npm install @saber2pr/aystore

# from github
git clone https://github.com/Saber2pr/-saber2pr-aystore.git

API

1. store.body

返回 store requestListener 处理程序

const store = AyStore()

store.body()

// store.use(store.body())

2. store.use

注册一个 requestListener

const store = AyStore()

store.use(async ctx => {
  if (ctx.request.url === '/hello') {
    ctx.response.end('hello!')
  }
})

3. store.context

在 requestListener 间传递的上下文

const store = AyStore({ name: 'aystore' })

store.use(async (ctx, next) => {
  ctx.name // 'aystore'
  store.context // 'aystore'
})

4. store.request

发起一个请求

const store = AyStore()

store.use(async ctx => {
  if (ctx.request.url === '/hello') {
    ctx.response.end('hello!')
  }
})

store.request({ url: '/hello' }).then(res => {
  console.log(res) // hello!
})

传递参数

const store = AyStore()

store.use(async ctx => {
  if (ctx.request.url === '/hello') {
    ctx.response.end('hello!', ctx.request.body)
  }
})

store.request({ url: '/hello', body: 'world!' }).then(res => {
  console.log(res) // ['hello!', 'world!']
})

协变

Typescript 对函数参数类型默认允许双向协变，但是它不安全！ 例如组合两个 AyStore 的 body 会涉及到 对 context 的依赖，如果允许双向协变，它将不会报错！

强烈建议开启：--strictFunctionTypes

{
  "compilerOptions": {
    "strictFunctionTypes": true
  }
}

develope and test

you should write ts in /src

you should make test in /src/test

export your core in /src/index.ts!
