description	Create or update Storybook stories for Daedalus React components. Use this when asked to write stories, visual tests, storybook entries, or component demos for new or existing features.

Storybook Creation Skill

Create or update Storybook stories for the Daedalus wallet application. This skill covers writing .stories.tsx files, domain wrappers, mock data, and registering stories — following existing project conventions.

Storybook Stack

Component	Technology
Storybook	6.4 with webpack5 builder
Story API	storiesOf() (legacy API — NOT CSF)
Knobs	@storybook/addon-knobs
Actions	@storybook/addon-actions
State Management	@dump247/storybook-state (withState)
Custom Addon	DaedalusMenu (theme/locale/OS switcher)
Styling	SCSS Modules (co-located with components)
i18n	react-intl (en-US, ja-JP)
Component Library	react-polymorph (via StoryDecorator)

Important: Daedalus uses the storiesOf() API, NOT Component Story Format (CSF). Do NOT use export default { title: ... } or named exports.

Directory Structure

Centralized Stories (default)

Stories are organized by domain under storybook/stories/:

storybook/stories/
├── index.ts                    # Master entry — imports all story files
├── _support/                   # Shared infrastructure
│   ├── StoryWrapper.tsx        # Top-level wrapper (theme/locale/OS)
│   ├── StoryDecorator.tsx      # react-polymorph ThemeProvider
│   ├── StoryProvider.tsx       # MobX provider + mock data
│   ├── StoryLayout.tsx         # Full app UI shell (sidebar/topbar)
│   ├── config.ts               # Theme/locale/OS constants
│   ├── utils.ts                # Mock data generators

└── nodes/                      # Node status

Co-located Stories (feature modules)

For self-contained feature modules, stories can live next to the component:

source/renderer/app/features/{feature}/ui/
├── MyComponent.tsx
├── MyComponent.scss
└── MyComponent.story.tsx       # Co-located story

When to Use Which Pattern

Pattern	When to Use
Centralized	Default for all domain-level features (wallets, staking, etc.)
Co-located	Self-contained feature modules under source/renderer/app/features/

---

Step 1: Determine Story Location

New domain in storybook/stories/

Create a new directory and optionally a domain barrel file:

storybook/stories/{domain}/
├── index.ts                           # Optional barrel import
├── {FeatureName}.stories.tsx          # Story file
└── _utils/                            # Optional domain wrapper
    └── {Domain}Wrapper.tsx

Existing domain

Add the story file to the appropriate subdirectory:

storybook/stories/{domain}/{sub-feature}/
└── {FeatureName}.stories.tsx

Co-located feature story

source/renderer/app/features/{feature}/ui/
└── {ComponentName}.story.tsx

---

Step 2: Write the Story File

File Naming

Pattern	Convention	Example
Centralized	{ComponentName}.stories.tsx	WalletSend.stories.tsx
Co-located	{ComponentName}.story.tsx	DiscreetModeToggle.story.tsx

Story Naming Convention

Use storiesOf('Domain / Sub-feature', module) with / as separator:

storiesOf('Wallets / Send', module)
storiesOf('Common / Widgets', module)
storiesOf('Staking', module)
storiesOf('Discreet Mode / Discreet Mode Toggle', module)

Minimal Story Template

import React from 'react';
import { storiesOf } from '@storybook/react';
import { action } from '@storybook/addon-actions';
import { withKnobs, boolean, text, number } from '@storybook/addon-knobs';
import MyComponent from '../../../../source/renderer/app/components/{domain}/MyComponent';

storiesOf('{Domain} / {Feature}', module)
  .addDecorator(withKnobs)
  .add('default', () => (
    <MyComponent
      label={text('Label', 'Default')}
      disabled={boolean('Disabled', false)}
      onClick={action('onClick')}
    />
  ));

Full Story Template (with decorators + state)

import React from 'react';
import { storiesOf } from '@storybook/react';
import { action } from '@storybook/addon-actions';
import { observable, action as mobxAction } from 'mobx';
import {
  withKnobs,
  boolean,
  text,
  number,
  select,
} from '@storybook/addon-knobs';
import StoryDecorator from '../_support/StoryDecorator';
import StoryProvider from '../_support/StoryProvider';
import StoryLayout from '../_support/StoryLayout';
import MyComponent from '../../../../source/renderer/app/components/{domain}/MyComponent';

storiesOf('{Domain} / {Feature}', module)
  .addDecorator((story: any, context: any) => {
    const onChangeAction = action('onChange');
    const state = observable({
      : ,
      : ( {
        state. = newValue;
        (newValue);
      }),
    });
     (
      
    );
  })
  .(withKnobs)
  .(,  (
    
  ))
  .(,  (
    
  ))
  .(,  (
    
  ));

Story with withState (for interactive two-way binding)

import { withState } from '@dump247/storybook-state';

storiesOf('{Domain} / {Feature}', module)
  .addDecorator(withKnobs)
  .add(
    'interactive',
    withState({ value: '' }, (store) => (
      <MyInput
        value={store.state.value}
        onChange={(value) => store.set({ value })}
      />
    ))
  );

---

Step 3: Use Support Infrastructure

Decorator Stack

The standard decorator stack wraps stories with theme, intl, and layout:

Decorator	Purpose	Import Path
StoryWrapper	Top-level: theme, locale, OS selection (auto-applied)	../_support/StoryWrapper
StoryDecorator	react-polymorph ThemeProvider + skin	../_support/StoryDecorator
StoryProvider	MobX store provider + mock data	../_support/StoryProvider
StoryLayout	Full app shell (sidebar, topbar, content area)	../_support/StoryLayout

StoryWrapper is automatically applied via storybook/preview.tsx — do NOT add it manually.

When to use each:

• Simple component (no app context needed): Just withKnobs decorator — no StoryDecorator/Provider/Layout.
• Component needing theme: Add StoryDecorator.
• Component needing MobX stores: Add StoryDecorator + StoryProvider.
• Full page/screen component: Add all three: StoryDecorator + StoryProvider + StoryLayout.

Domain Wrappers

For domains with shared layout (e.g., wallets with navigation tabs), create a domain wrapper:

// storybook/stories/{domain}/_utils/{Domain}Wrapper.tsx
import React from 'react';
import { withKnobs } from '@storybook/addon-knobs';
import StoryLayout from '../../_support/StoryLayout';
import StoryProvider from '../../_support/StoryProvider';
import StoryDecorator from '../../_support/StoryDecorator';

export default function (story: any, context: any) {
  const storyWithKnobs = withKnobs(story, context);
  return (
    <StoryDecorator>
      <StoryProvider>
        <StoryLayout activeSidebarCategory="/{domain}" {...context}>
          {storyWithKnobs}
        </StoryLayout>
      </StoryProvider>
    </StoryDecorator>
  );
}

Use it in stories:

import DomainWrapper from '../_utils/DomainWrapper';

storiesOf('{Domain} / {Feature}', module)
  .addDecorator(DomainWrapper)
  .add('default', () => <MyComponent />);

activeSidebarCategory Values

Category	Value
Wallets	/wallets
Staking	/staking
Settings	/settings
Voting	/voting
None/Other	null

---

Step 4: Mock Data

Available Mock Data Generators

Import from storybook/stories/_support/utils.ts:

import {
  generateHash,
  generatePolicyIdHash,
  generateWallet,
  generateTransaction,
  generateAssetToken,
  generateAssetDomain,
  generateRewardForWallet,
  EXAMPLE_METADATA,
} from '../_support/utils';

Generator	Returns	Key Parameters
generateHash()	SHA-512 hex string	(none)
generatePolicyIdHash()	SHA-224 hex string	(none)
generateWallet()	Wallet instance	name, amount, assets, reward, delegatedStakePool, hasPassword, status, isHardwareWallet, id
generateTransaction()	WalletTransaction	type, date, amount, deposit, state, ...
generateAssetToken()	AssetToken object	policyId, assetName, fingerprint, quantity, metadata
generateAssetDomain()	Asset instance	policyId, assetName, fingerprint, metadata
generateRewardForWallet()	Reward object	wallet, unspent

Example mock data setup

import BigNumber from 'bignumber.js';
import { generateWallet, generateAssetToken, generateHash } from '../_support/utils';
import Wallet, { WalletSyncStateStatuses } from '../../../../source/renderer/app/domains/Wallet';

const wallet = generateWallet('Test Wallet', '500000000');
const syncingWallet = generateWallet(
  'Syncing Wallet',
  '100000000',
  { available: [], total: [] },
  0,
  null,
  false,
  WalletSyncStateStatuses.SYNCING
);
const asset = generateAssetToken(
  '65bc72542b0ca20391caaf66a4d4e7897d282f9c136cd3513136945c',
  '',
  'token_fingerprint_here',
  100,
  { name: 'TestToken', ticker: 'TT', description: 'A test token', url: '', logo: '' }
);

---

Step 5: Register the Story

Centralized stories

Add the import to the appropriate barrel file:

1. If a domain index.ts exists (e.g., storybook/stories/wallets/index.ts):

   import './{sub-feature}/{FeatureName}.stories';
   

2. If no domain index.ts exists, add the import to storybook/stories/index.ts:

   // {Domain}
   import './{domain}/{FeatureName}.stories';
   

Co-located stories

Add the import to storybook/stories/index.ts with the full relative path:

import '../../source/renderer/app/features/{feature}/ui/{ComponentName}.story';

Registration Checklist

• Story file created with correct naming convention
• Import added to domain index.ts OR root storybook/stories/index.ts
• Story renders in Storybook without errors

---

Step 6: Cover Component States

Every story file should demonstrate the component's key visual states:

Required States

storiesOf('{Domain} / {Feature}', module)
  .addDecorator(/* ... */)
  .add('default', () => <Component /* happy path props */ />)
  .add('loading', () => <Component isLoading />)
  .add('empty', () => <Component items={[]} />)
  .add('error', () => <Component error="Something went wrong" />);

Recommended Additional States

State	When to Include
disabled	Component can be disabled
with data	Component needs populated mock data
hardware wallet	Component behaves differently for HW wallets
syncing	Component shows sync progress
restoring	Component shows restore progress
legacy wallet	Component has legacy wallet variant
with knobs	Interactive prop editing for complex components

---

Knobs Reference

Use @storybook/addon-knobs for interactive props:

import {
  withKnobs,
  text,       // text('Label', 'default value')
  boolean,    // boolean('Disabled', false)
  number,     // number('Count', 5)
  select,     // select('Size', { Small: 'sm', Large: 'lg' }, 'sm')
  date,       // date('Start Date')
  object,     // object('Config', { key: 'value' })
  array,      // array('Items', ['a', 'b'])
} from '@storybook/addon-knobs';

---

Updating Existing Stories

When updating stories for an existing feature:

1. Find the existing story file — search storybook/stories/ or source/renderer/app/features/ for .stories.tsx or .story.tsx files.
2. Add new story entries — append .add() calls for new states/variants.
3. Update mock data — if the component's props changed, update mock data to match.
4. Update imports — if new dependencies are needed, add them.
5. Do NOT change the storiesOf() title unless the feature was renamed.

Adding a new state to an existing story

// Find the existing storiesOf chain and append:
  .add('new state name', () => (
    <ExistingComponent
      newProp={text('New Prop', 'value')}
      /* existing required props */
    />
  ));

---

Internationalization in Stories

For components using react-intl messages:

import { defineMessages, IntlProvider } from 'react-intl';
import enMessages from '../../../../source/renderer/app/i18n/locales/en-US.json';
import jpMessages from '../../../../source/renderer/app/i18n/locales/ja-JP.json';

const { intl: enIntl } = new IntlProvider({
  locale: 'en-US',
  messages: enMessages,
}).getChildContext();

// Use in story:
.add('with i18n', (_, props) => (
  <Component
    label={enIntl.formatMessage(messages.myLabel)}
  />
))

Note: StoryWrapper already provides IntlProvider globally. You only need manual intl setup when you need to access intl.formatMessage() directly in story code (not in the component).

---

Common Pitfalls

Pitfall	Solution
Story not appearing in Storybook	Ensure import is added to index.ts barrel file
Blank/white story	Missing StoryDecorator (theme provider) — add it as a decorator
MobX errors	Component needs stores — add StoryProvider decorator
Missing sidebar/layout	Add StoryLayout decorator with correct activeSidebarCategory
Styles not loading	SCSS modules are auto-loaded; check component imports
storiesOf title not grouping	Use / separator (with spaces): 'Domain / Feature'
Using CSF exports	Daedalus uses storiesOf() API — do NOT use export default
Arrow functions in decorators	Use function keyword if you need this context

---

Validation

After creating or updating a story:

1. Build check: yarn storybook:build — story must compile without errors
2. Visual check: yarn storybook — story renders correctly at http://localhost:6006
3. Theme check: Switch themes in the DaedalusMenu addon — verify all themes render properly
4. Locale check: Switch to Japanese locale — verify i18n strings render
5. State coverage: Verify all visual states are represented (default, loading, error, empty, etc.)

---
