A simple gist that uses redux without react.

redux_plain.js

// Quotes App
const { createStore } = require("redux");


// Reducer - updates the store
const initialState = [
  {
    author: "Walt Disney",
    quote: "The way to get started is to quit talking and begin doing."
  }
];

const reducer = (state = initialState, action) => {
  switch (action.type) {
    case "ADD_QUOTE":
      return [...state, action.payload];
    default:
      return state;
  }
};

// Store - the single source of truth
const store = createStore(reducer);
// console.log(store.getState());

// Subscription - listens for actions and store updates
store.subscribe(() => {
  console.log(store.getState());
});

// Actions - information that is sent to the reducer
const addQuote = (author, quote) => ({
  type: "ADD_QUOTE",
  payload: { author, quote }
});

store.dispatch(
  addQuote(
    "John Lennon",
    "Life is what happens when you're busy making other plans."
  )
);

// Dispatches after 3 seconds.
// Used to show that the subscription listens for store updates.
// The subscription executes a console.log() when this action is dispatched
setTimeout(() => {
  store.dispatch(
    addQuote("Anne Frank", "Whoever is happy will make others happy too.")
  );
}, 3000);

// console.log(store.getState());
