storybook-addon-code-editor

A Storybook add-on for live editing stories. Supports React and TypeScript.

Demo

Example code using this add-on

Get started

Install as a dev dependency.

npm install --save-dev storybook-addon-code-editor

Add storybook-addon-code-editor in your .storybook/main.ts file and ensure the staticDirs, addons, and framework fields contain the following:

// .storybook/main.ts
import type { StorybookConfig } from '@storybook/react-vite';
import { getCodeEditorStaticDirs } from 'storybook-addon-code-editor/getStaticDirs';

const config: StorybookConfig = {
  staticDirs: [...getCodeEditorStaticDirs(__filename)],
  addons: ['storybook-addon-code-editor'],
  framework: {
    name: '@storybook/react-vite',
    options: {},
  },
};

export default config;
About `staticDirs`

staticDirs sets a list of directories of static files to be loaded by Storybook. The editor (monaco-editor) requires these extra static files to be available at runtime.

Additional static files can be added using the getExtraStaticDir helper from storybook-addon-code-editor/getStaticDirs:

// .storybook/main.ts
import {
  getCodeEditorStaticDirs,
  getExtraStaticDir,
} from 'storybook-addon-code-editor/getStaticDirs';

const config: StorybookConfig =  {
  staticDirs: [
    ...getCodeEditorStaticDirs(),

    // files will be available at: /monaco-editor/esm/*
    getExtraStaticDir('monaco-editor/esm'),

Important:

@storybook/react-vite is the only supported framework at this time.


API

Playground

Use the Playground component in MDX format.

// MyComponent.stories.mdx
import { Playground } from 'storybook-addon-code-editor';

<Playground code="export default () => <h1>Hello</h1>;"} />
More advanced example
// MyComponent.stories.mdx
import { Playground } from 'storybook-addon-code-editor';
import * as MyLibrary from './index';
import storyCode from './MyStory.source.tsx?raw';

// TypeScript might complain about not finding this import or
// importing things from .d.ts files wihtout `import type`.
// Ignore this, we need the string contents of this file.
// @ts-ignore
import MyLibraryTypes from '../dist/types.d.ts?raw';

<Playground
  availableImports={{ 'my-library': MyLibrary }}
  code={storyCode}
  height="560px"
  id="unique id used to save edited code until the page is reloaded"
  modifyEditor={(monaco, editor) => {
    // editor docs: https://microsoft.github.io/monaco-editor/api/interfaces/monaco.editor.IStandaloneCodeEditor.html
    // monaco docs: https://microsoft.github.io/monaco-editor/api/modules/monaco.html
    editor.getModel().updateOptions({ tabSize: 2 });
    monaco.editor.setTheme('vs-dark');
    monaco.languages.typescript.typescriptDefaults.addExtraLib(
      MyLibraryTypes,
      'file:///node_modules/my-library/index.d.ts'
    );
  }}
/>;

Playground props:

interface PlaygroundProps {
  availableImports?: {
    [importSpecifier: string]: {
      [namedImport: string]: any;
    };
  };
  code?: string;
  height?: string;
  id?: string | number | symbol;
  modifyEditor?: (monaco: Monaco, editor: Monaco.editor.IStandaloneCodeEditor) => any;
}

React is automatically imported if code does not import it. React TypeScript definitions will be automatically loaded if @types/react is available.

createLiveEditStory

Use the createLiveEditStory function in traditional stories:

// MyComponent.stories.ts
import type { Meta, StoryObj } from '@storybook/react';
import { createLiveEditStory } from 'storybook-addon-code-editor';
import * as MyLibrary from './index';
import storyCode from './MyStory.source.tsx?raw';

const meta = {
  // Story defaults
} satisfies Meta<typeof MyLibrary.MyComponent>;

export default meta;

type Story = StoryObj<typeof meta>;

export const MyStory = createLiveEditStory<Story>({
  availableImports: { 'my-library': MyLibrary },
  code: storyCode,
});

createLiveEditStory options:

interface LiveEditStoryOptions {
  availableImports?: {
    [importSpecifier: string]: {
      [namedImport: string]: any;
    };
  };
  code: string;
  modifyEditor?: (monaco: Monaco, editor: Monaco.editor.IStandaloneCodeEditor) => any;
  // Any other Storybook story options, e.g. `args`, `parameters`, etc..
}

setupMonaco

setupMonaco allows customization of monaco-editor.

Use this in your .storybook/preview.ts to add type definitions or integrations.

Check out examples of monaco-editor with different configurations.

// .storybook/preview.ts
import { setupMonaco } from 'storybook-addon-code-editor';

setupMonaco({
  // https://microsoft.github.io/monaco-editor/typedoc/interfaces/Environment.html
  monacoEnvironment: {
    getWorker(moduleId, label) {
      ...
    },
  },
  // onMonacoLoad is called when monaco is first loaded and before an editor instance is created.
  onMonacoLoad(monaco) {
    ...
  },
});

setupMonaco options:

interface MonacoSetup {
  monacoEnvironment?: Monaco.Environment;
  onMonacoLoad?: (monaco: Monaco) => any;
}
