Plugging redux in

The most straightforward way to plug in Redux:

1. Create initial state of your app

// initial-state.js
const initialState = {
  user: null,
  todos: {
    active: [],

snigo

const button = document.getElementById('btn');

function handleClick(clickEvent) {
  /** React on click event */
}

button.addEventListener('click', handleClick);

snigo

const API_URL = 'https://mysuperduperapp.com/api';

function parseResponse(response) {
  /** React on response event */
  return response.json();
}
function handleResponse(data) {
  /** React on successful parsing (job done) event */
}

snigo

function handleRequest(req, res) {
  /** React on GET request */
}

router.get('/api/topic/:id', handleRequest);

snigo

/** Accessing files */
fs.readFile('./index.html', handleDoneReading);

/** Dealing with streams */
httpClient.get(API_URL)
  .subsribe(handleObservableData);

/** Accessing database */
User.findOne({ name: 'Igor' }, handleFoundData);
