Sorry, but you either have no stories or none are selected somehow.

If the problem persists, check the browser console, or the terminal you've run Storybook from.

Vanilla - basic usage
Create a store
The exported functions can be used anywhere - in component, utils file, event listener, setTimeout, setInterval and promise callbacks.
VanillaStore
import GStatem from "gstatem";

const initialState = { count: 0 };
const { get, set, select, dispatch } = new GStatem({
  state: initialState
});

export const countSelector = state => state.count;

export const getCount = get(countSelector);

/* select count for non function component */
export const selectCount = subscribe => select(countSelector, subscribe);

/* increase the counter */
export const increaseCount = () =>
  dispatch(state => ({ count: state.count + 1 }));

/* reset counter */
export const resetCount = options => set(initialState, options);
Use the store in pure javascript
VanillaBasicUsage
import {
  increaseCount,
  resetCount,
  getCount,
  selectCount
} from "./VanillaStore";

/* select count */
const [count, unsubCount] = selectCount(state =>
  console.log("updated count", state.count)
);
console.log(count); // count is 0

increaseCount();
console.log(getCount()); // count is 1

/* reset count */
resetCount();
console.log(getCount()); // count is 0

window.onbeforeunload = () => {
  /* unsubscribe count on page unload */
  unsubCount();
};
