Connecting React Component with Redux Store - redux

Question

Very basic simple GET example for react-redux
I have a "MockAPI" which simulates a GET request to an API like so:
const dashboards = [
{
"Id":1,
"title":"Overview"
},
{
"Id":2,
"title":"Overview"
},
{
"Id":3,
"title":"Overview"
},
{
"Id":4,
"title":"Overview"
}
];
class DashboardApi {
static getAllDashboards() {
return new Promise((resolve) => {
setTimeout(() => {
resolve(Object.assign([], dashboards));
}, delay);
});
}
}
I am trying to develop in a react-redux flow of dispatching an action via a button click and then updating the component via the redux store.
Here is my component code:
import React, { PropTypes } from 'react';
import { connect } from 'react-redux';
import * as dashboardActions from '../../actions/dashboardActions';
class HomePage extends React.Component {
constructor(props) {
super(props);
this.loadDashboards = this.loadDashboards.bind(this);
}
loadDashboards() {
this.props.dispatch(dashboardActions.loadDashboards());
}
dashboardItem(dashboard, index) {
return <p key={index}>{dashboard.title}</p>;
}
render() {
return (
<div>
<h1>
Hello World!
<button onClick={this.loadDashboards}>load</button>
</h1>
{this.props.dashboards.map(this.dashboardItem)}
</div>
);
}
}
HomePage.propTypes = {
dashboards: PropTypes.array.isRequired,
dispatch: PropTypes.func.isRequired
};
function mapStateToProps(state) {
return {
dashboards: state.dashboards
};
}
export default connect(mapStateToProps)(HomePage);
And here is my dashboardActions.js:
import * as types from './actionTypes';
import dashboardApi from '../mockApi/mockDashboardApi';
export function loadDashboardsSuccess(dashboards) {
return { type: types.LOAD_DASHBOARDS_SUCCESS, dashboards };
}
export function loadDashboards() {
return dispatch => {
return dashboardApi
.getAllDashboards()
.then(dashboards => {
dispatch(loadDashboardsSuccess(dashboards));
});
};
}
And here is my reducer:
import initialState from './initialState';
import * as types from '../actions/actionTypes';
export default function dashboardReducer(state = initialState.dashboards, action) {
switch(action.types) {
case types.LOAD_DASHBOARDS_SUCCESS:
return action.dashboards;
default:
return state;
}
}
I am trying to get the onClick to load in the dashboards array and to render as <p> tags simply displaying the title value. Unfortunately it is not happening.
I see that the LOAD_DASHBOARDS_SUCCESS action is getting loaded, but I see that the dashboards property in the store is still an empty array instead of showing the returned data...
What am I missing here?

You've got a typo in your reducer. switch(action.types) should be switch(action.type) with no 's'
