How to get data with api with one action and reducer in React + Redux?

Question

React

Came from Angular 2 to React + Redux.
In Angular, he described base.service, which implemented all the basic methods for working with data.
And then the components were simply typed as a constructor, referring to this base.service.
How to implement similar generic base.reducer and base.action in Redux?
I'm sure there are examples, but I can't find them.
To begin with, I try to pull data (ex. users, hospitals) from api using one reducer and one action, calling the fetchData (url) action. But then I don’t understand how to save the data in the store with the reducer, corresponding to the response from the api. To be store.users and store.hospitals.

Answer 1

maybe something like this..

const myState = {
  users: [],
  hospitals: []
}

const myReducer = (state = myState, action) => {
  if( action.type === 'FETCH_DATA' ) {
    return myState[action.storeType].concat(data)
  }

  return state
}

const fetchData = (url) => {
  fetch(...).then(data => {
    return {
      type: "FETCH_DATA",
      data: data.result,
      storeType: data.type
    }
  })
}
