Reactjs, Redux - redux-persist

I am working on a reactjs/redux application - and using a Java Spring Boot codebase acting as an api.

I've got a login system in place - but I notice that when I refresh the page -- the authentication state is lost.

I've added redux-persist, but it doesn't appear to take any affect in stashing the logged in state and resuming the experience?

The bulk of the redux-persist is in place on my router.js --- its here where the store/provider gets set to the application.

I am unsure how and where to store the state when the user has logged in -- I've exposed the form for the login and you can see I start to check the this.props.authData states -- where it would be ideal to call persistor.rehydrate() -- but then I don't have access to the persistor or the store on those pages?

Update 1: 14/09/2017

this is what my authAction.js looks like

//authAction.js

    import axios from 'axios';

    export const FETCH_AUTH_SUCCESS = 'FETCH_AUTH_SUCCESS'
    export const FETCH_AUTH_FAILURE = 'FETCH_AUTH_FAILURE'
    export const FETCH_AUTH_CLEAR = 'FETCH_AUTH_CLEAR'

    export function authSuccess(response) {
      return {
        type: FETCH_AUTH_SUCCESS,
        payload: response
      }
    }

    export function authFail(response) {
      return {
        type: FETCH_AUTH_FAILURE,
        payload: response
      }
    }

export function authClear() {
  return {
    type: FETCH_AUTH_CLEAR,
    payload: null
  }
}


export function fetchAuthentication(data) {

  let url = 'http://localhost:8080/login';

  return function (dispatch) {     
     //axios.post(url, data)
   axios.get(url, {
      params: data
    })
      .then(function (response) {
        console.log(response);

      if(response.data.status === "success"){
        dispatch(authSuccess(response));
      }
      else{
        // fail - user not found for example
        dispatch(authFail(response));
      }

      })
      .catch(function (error) {
        //console.log(error);
        dispatch(authFail(error));
      });
  }
}


export function clearAuthentication() {

  let url = 'http://localhost:8080/logout';

  return function (dispatch) {     
   //axios.post(url, data)
   axios.get(url)
    .then(function (response) {
      console.log(response);

      if(response.data.status === "success"){
        dispatch(authClear(response));
      }
      else{
        // fail - user not found for example
        dispatch(authFail(response));
      }

    })
    .catch(function (error) {
      //console.log(error);
      dispatch(authFail(error));
    });
  }
}

//authReducer.js

import { FETCH_AUTH_SUCCESS, FETCH_AUTH_FAILURE, FETCH_AUTH_CLEAR } from '../actions/authAction'

export function authReducer (state = {}, action) {
  //console.log('reducer act', action)
  switch (action.type) {
    case FETCH_AUTH_SUCCESS:
      return {...state, data: action.payload, isLogged: true};
    case FETCH_AUTH_FAILURE:
      return {...state, data: action.payload, isLogged: false}; 
    case FETCH_AUTH_CLEAR:
      return {...state, data: action.payload, isLogged: false};
    default:
      return {...state} 
  }
}

as per "Steven Daniel Anderson" answer

"

const user = localStorage.getItem('user')
if(user){
    //Set the state authenticated to true;
    store.dispatch({
        type:AUTH_USER
    })
}

"

be something more like

const user = localStorage.getItem('user')
if(user){
    //Set the state authenticated to true;
    authSuccess(user)
}

or in my action create a new function like this

export function fetchResumeAuth(data) {
   dispatch(authSuccess(data));
}

and then in the user check -- which would be placed in the router.js?

const user = localStorage.getItem('user')
if(user){
    //Set the state authenticated to true;
    fetchResumeAuth(user)
}
