Redux Promise Middleware enables simple, yet robust handling of async action creators inRedux.

constasyncAction=()=>({type:'PROMISE',payload:newPromise(...),})

Given a single action with an async payload, the middleware transforms the action to a separate pending action and a separate fulfilled/rejected action, representing the states of the async action.

The middleware can be combined withRedux Thunk to chain action creators.

constsecondAction=(data)=>({type:'SECOND',payload:{...},})constfirstAction=()=>{return(dispatch)=>{constresponse=dispatch({type:'FIRST',payload:newPromise(...),})response.then((data)=>{dispatch(secondAction(data))})}}
