To use context providers in Storybook, you can follow these steps:

  1. Install the necessary dependencies: Make sure you have installed the @storybook/addons package by running the following command:
1
npm install @storybook/addons


  1. Create a new context provider in your application: You can create a new context provider in your React application using the React.createContext() function. This will define a new context that you can use to provide data to your components.
  2. Wrap your components in the context provider: In your Storybook stories, you can wrap your components in the context provider so that they receive the data from the context. You can do this using the addDecorator() function provided by Storybook.


Here's an example of how you can use context providers in Storybook:

// MyContextProvider.js
import React, { createContext, useContext } from 'react';

const MyContext = createContext();

export const MyContextProvider = ({ children }) => {
  const value = 'Hello from context!';

  return (
    <MyContext.Provider value={value}>
      {children}
    </MyContext.Provider>
  );
};

export const useMyContext = () => {
  return useContext(MyContext);
};

// MyComponent.stories.js
import React from 'react';
import { MyComponent } from './MyComponent';
import { MyContextProvider } from './MyContextProvider';

export default {
  title: 'MyComponent',
  component: MyComponent,
  decorators: [
    (Story) => (
      <MyContextProvider>
        <Story />
      </MyContextProvider>
    ),
  ],
};

export const Default = () => <MyComponent />;


In this example, we have created a context provider called MyContextProvider that wraps our MyComponent in the Storybook story file. The useMyContext hook can be used inside the MyComponent to access the data from the context provider.


By following these steps, you can effectively use context providers in Storybook to provide data to your components.
