Simple Instance

import {CacheHttp} from 'cache-ajax';
window['myHttp']=new CacheHttp();

myHttp
.xhr('get','http://localhost:3000/get',{name:1})
.subscribe(
    result=>console.log(result),
    err=>console.log(err)
)

Advance Instance:

const sub=myHttp.xhr('post','http://localhost:3000/get',{name:1},{
  headers:{storeCode:1},
  expires:.5
})
let order;
const click=()=>order=sub.subscribe(result=>console.log(result));
const cancel=()=>order&&order.unsubscribe();

If your request takes 5 seconds,you have to disabled button during this times.

Now,you don't need to worry it.

cacheAjax will make the last event take effective, before the request completed.

Specify key

myHttp.xhr('get',address,null,{key:'getUser'})
