intro

a lightweight fetch lib with middleware inspired by koa

quick start

yarn add @jarzzzi/rufetch

example

const http = new Rufetch({
  baseURL: 'https://github.com/api',
})

const getUser = (name) => {
  return http.get(`/user/${name}`)
}

const getReps = (name, page) => {
  return http.get(`/user/${name}`, {params: {page}})
}

const createReps = (name, data) => {
  return http.post(`/user/${name}`, {data})
}

middleware

  • built in middleware

    • cache
    • fetch
  • error middleware

http.use(async (ctx: any, next: any) => {
  await next()
  const {error} = ctx.res

  if (error?.status >= 400 && error?.status < 500) {
    console.error('client error')
  }
  if (error?.status >= 500) {
    console.error('server error')
  }
  if (error === 'fetch timeout') {
    console.error('fetch timeout')
  }
})
  • token middleware
http.use(async (ctx: any, next: any) => {
  const token = await getToken()
  ctx.req.requestInit.setHeaders(token, token)
  await next()
})

    • window
  • new (options)
  • instance.get
  • instance.post
