React-

It's long to navigate to the location of my component in my app after making a change

What if my visual change break other components?

I wasn't aware that this component was even existing

How can I enable people to quickly contribute to my component?

I'd like to have a visual documentation of my component

I got warnings and had to manually add react-dom to package.json

Write stories

import React from 'react';
import { storiesOf } from '@storybook/react';

storiesOf('SearchBar', module)
  .add('default', () => (
    <SearchBar 
      value="Blabla" 
      hint="Enter your search keyword"
    />
  ));
storiesOf('SearchBar', module)
  .add('default', () => ...)
  .add('display an error', () => (
    <SearchBar error="No internet connection"/>
  ));

Log actions

//...
import { action } from '@storybook/addon-actions';

storiesOf('SearchBar', module)
  .add('default', () => (
    <SearchBar 
      value="Blabla" 
      onSearch={action('search launched')}
    />
  ));

Decorators

// Decorator to allow material-ui components
// to read the app theme
const muiDecorator = (story) => (
  <MuiThemeProvider muiTheme={defaultTheme}>
    {story()}
  </MuiThemeProvider>
)

// Add you decorator to any story using material-ui
storiesOf('AboutDialog', module)
  .addDecorator(muiDecorator)
  .add('default', () => <AboutDialog open />);

Or just components

// You can create a helper component and reuse it:
const Serializer = props => (
  <div>{props.children} {JSON.stringify(props.object)}</div>
);

storiesOf('ProfilePage', module).add('default', () => (
  <Serializer object={profile}>
    <ProfilePage profile={profile} />
  </Serializer>
));

storiesOf('CartItemsList', module).add('default', () => (
  <Serializer object={items}>
    <CartItemsList items={items} />
  </Serializer>
));

Fixtures/mocking data

// Create fixtures, or better, share them with your unit tests :)
import complexFakeData from './fixtures/my-complex-data.json';

storiesOf('Dashboard', module)
  .add('default', () => <Dashboard data={complexFakeData} />);
