intro

a lightweight fetch lib with middleware inspired by koa

quick start

yarn add @jarzzzi/rufetch

example

consthttp=newRufetch({baseURL: 'https://github.com/api',})constgetUser=(name)=>{returnhttp.get(`/user/${name}`)}constgetReps=(name,page)=>{returnhttp.get(`/user/${name}`,{params: {page}})}constcreateReps=(name,data)=>{returnhttp.post(`/user/${name}`,{data})}

middleware

• built in middleware

  • cache
  • fetch

• error middleware

http.use(async(ctx: any,next: any)=>{awaitnext()const{error}=ctx.resif(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)=>{consttoken=awaitgetToken()ctx.req.requestInit.setHeaders(token,token)awaitnext()})
