const simpleEpic = is => is('SUBMIT_SEARCH')

  .map(({payload, store, dispatch}) => fetch(payload)

    .then(res => res.json())

    .then(json => dispatch(searchResponse(json)))

    .catch(e => dispatch(seachError(e))))

// Dispatch multiple actions with an array

const multipleEpic = is => is('SUBMIT_SEARCH')

  .map(({payload, store, dispatch}) => fetch(payload)

    .then(res => res.json())

    .then(json => dispatch([searchResponse(json), clearSidebar()]))

    .catch(e => dispatch(seachError(e)))

  )

export default [simpleEpic, multipleEpic]

// index.js

import prosciutto from 'prosciutto'

import epics from './epics'

const store = createStore(

  reducers,

  applyMiddleware(prosciutto(epics))

)
