Have any good way to implement multi promise control like Async?

[hank7444]

example1, I have 3 apis need to call, if they all resolve, return success and get me all data which return by those apis. If one of them are rejected, return failure to me.

example2, I have 2 apis need to call, if one of them resolve, return success and get me data.
If all of them are rejected, return failure to me.

Have any possible do such like these sophisticated async control on redux?

I have already used apiMiddleware, but it only use on 1 ajax call..

It is not a Redux thing. You can do it with native promise

example 1

Promise.all([callAPI1(), callAPI2(), callAPI3()]).then(onSucces, onFailure)

example 2

Promise.race([callAPI1(), callAPI2(), callAPI3()]).then(onSucces, onFailure)

then you can wrap it code in action using https://github.com/gaearon/redux-thunk or https://github.com/acdlite/redux-promise and it will work

Look at the docs on MDN if you want more information

@just-boris thx! I will try it~

Also, for combining async actions you can use redux-combine-actions.

Yes, we suggest using middleware like redux-thunk or redux-promise for this. You can then use Promise.all and other Promise composition functions. Note that you need to include a polyfill for Promises to use them safely—for example, you may use the polyfill that ships with Babel by importing babel-core/polyfill.
