i have a problem with redux-thunk, it just doesn't pass the dispatch to my action creator, i'm loggin it but it is still undefined:

here is my action creator:

import * as types from './actionTypes'

import Service from '../service'







export const fetchFromApi = payload => {

  return { type: types.FETCH_FROM_API_TEST, payload }

}





export const fetchApiTestAction = () => dispatch => {

  return Service.GetUsers().then( _data => {

    dispatch(fetchFromApi( _data.data )) // you can even distructure taht like fetchFromApi(({ data }))

  }).catch ( err => {

    // error catching here 

    // you can even call an failure action here...

    // but sorry about it , i have no time for that , im sorry :(

    throw (err)

  })

}

here is my Service js class

// Basic fetch

  async basicFetch(url, options, headers = this.authernticateHeader) {

    let fetchOptions = {}

    if(options.headers) {

      fetchOptions = {

        mode: 'cors',

        cache: 'default',

        ...options

      }

    } else {

      fetchOptions = {

        mode: 'cors',

        cache: 'default',

        ...options,

        headers

      }

    }





    // log before sending the request...

    // console.log(url, fetchOptions, fetchOptions.headers.get('Content-Type') )



    try {

      const response = await fetch(

        `${this.serverAddress}${url}`,

        { ...fetchOptions }

      )



      if(!response.ok) {

        throw {

          message: response.statusText,

          api: `${options.method} ${this.serverAddress}`

        }

      }



      const responseJson = await response.json()

      console.log('----------------------------')

      console.log(responseJson)

      console.log('----------------------------')

      return responseJson

    } catch(err) {

      throw { ...err }

    }

  }





  GetUsers = () => {

    return this.basicFetch(this.urls.GET_USERS, {

      method: 'GET'

    })

  }

here is my routes .js file

import { fetchApiTestAction } from './actions/fetchApiTestAction'







const routes = [



  {

    path: '/',

    exact: true,

    component: Home,

    fetchInitialData: fetchApiTestAction()

  },

  {

    path: '/about',

    component: About

  },

  {

    path: '/contact',

    component: Contact

  },



]

and here is my server.js file

app.get('/*', (req, res, next) => {



  const activeRoute = routes.find( route => matchPath(req.url, route) ) || {}



  const _promise = activeRoute.fetchInitialData 

    ? activeRoute.fetchInitialData()

    : Promise.resolve()



  _promise.then( () => {



    const store = configureStore()

    const markup = renderToString(



      <StaticRouter location={req.url} context={{}}>

        <Provider store={store}>

          <App />

        </Provider>

      </StaticRouter>

    )



    const initialBrowserTabText = 'hi there from home page...'

    const initialState = store.getState() || {}



    const _template = template( initialBrowserTabText, initialState, markup )



    res.send(_template)

  }).catch(err => {

    console.log(err)

  })

})

i havent faced with this kind of problem so far. when i console.log(dispatch) inside of my action creator(before return part) it is undefined. i should say that here is what my terminal shows to me:

Server is listening on port 8000...

----------------------------

{ page: 1,

  per_page: 3,

  total: 12,

  total_pages: 4,

  data: 

   [ { id: 1,

       first_name: 'George',

       last_name: 'Bluth',

       avatar: 'https://s3.amazonaws.com/uifaces/faces/twitter/calebogden/128.jpg' },

     { id: 2,

       first_name: 'Janet',

       last_name: 'Weaver',

       avatar: 'https://s3.amazonaws.com/uifaces/faces/twitter/josephstein/128.jpg' },

     { id: 3,

       first_name: 'Emma',

       last_name: 'Wong',

----------------------------

TypeError: dispatch is not a function

    at eval (webpack-internal:///./src/js/actions/fetchApiTestAction.js:17:7)

    at <anonymous>

    at process._tickCallback (internal/process/next_tick.js:188:7)

this means that im getting the data from api but why dispatch is not a function ????

That won't work unless you pass the redux-store dispatch property when you invoke fetchInitialData... Something like this:

  const _promise = activeRoute.fetchInitialData 

    ? activeRoute.fetchInitialData(store.dispatch)

    : Promise.resolve()

The real problem is that your redux-store doesn't even exist at that point, because you are configuring it after that promise has finished... So that's something else that you will have to address.
