What are @storybook/store's main functionalities?

State Management

This feature allows you to create and manage the state of your stories, including their parameters, args, and globals. The code sample demonstrates how to create a store, set its state, and retrieve the current state.

import { createStore } from '@storybook/store';

const store = createStore({
  stories: {},
  parameters: {},
  args: {},
  globals: {}
});

store.setState({
  stories: { 'example-story': { id: 'example-story', name: 'Example Story' } },
  args: { 'example-story': { arg1: 'value1' } }
});

console.log(store.getState());

Reactive State Updates

This feature allows you to subscribe to state changes and react to updates. The code sample demonstrates how to subscribe to state changes and log the updated state whenever it changes.

import { createStore } from '@storybook/store';

const store = createStore({
  stories: {},
  parameters: {},
  args: {},
  globals: {}
});

store.subscribe((state) => {
  console.log('State updated:', state);
});

store.setState({
  args: { 'example-story': { arg1: 'new-value' } }
});

Parameter Management

This feature allows you to manage parameters for your stories. The code sample demonstrates how to set parameters for a story and retrieve them from the store.

import { createStore } from '@storybook/store';

const store = createStore({
  stories: {},
  parameters: {},
  args: {},
  globals: {}
});

store.setState({
  parameters: { 'example-story': { param1: 'value1' } }
});

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