Add redux-optimist

[fresk-nc]

Do you want to add support "optimistically apply actions" with module redux-optimist?

[barrystaes]

Is this not already supported?
From the redux-optimist docs it appears a root optimist reducer (wrapping other reducers) and adding the optimist key in each FSA that your RSAA makes would work.. would it not?

Have not (yet) used it myself though.

How can I add optimist: {type: COMMIT, id: transactionID} for success action?

A quick search tells me that since 0.2.1 you can put optimist in meta so its a FSA compliant.

So i guess something like..

{
  [CALL_API]: {
    endpoint: 'http://www.example.com/api/users',
    method: 'GET',
    types: [
      'REQUEST',
      {
        type: 'SUCCESS',
        payload: (action, state, res) => {
          // whatever
        },
        meta: (action, state, res) => {
          optimist: {type: COMMIT, id: res.transactionID}          //    <---
        }
      },
      'FAILURE'
    ]
  }
}

But ofcourse for REQUEST and FAILURE you would have to also use optimist keys, and instead of getting the transaction id returned in a response you may want to use action or state to get it.

If you got this to work, we'd be happy to hear! I am going to have to do optimistic updates too in the foreseeable future.

@barrystaes did you ever manage to implement this?

[barrystaes]

@mmiszy Not this specific example. And I never put redux-api-middleware in actual production use so my experience using it is/was very limited. Having todays experience i'd probably just use a ES6 promise in the called action to achieve this.
