Storybook Centered Decorator

Storybook Centered Decorator can be used to center components inside the preview in Storybook.

This addon works with Storybook for:

React
Vue

Usage

npm install @storybook/addon-centered --save-dev

As a decorator

You can set the decorator locally.

example for React:

import { storiesOf } from '@storybook/react';
import centered from '@storybook/addon-centered';

import MyComponent from '../Component';

storiesOf('MyComponent', module)
  .addDecorator(centered)
  .add('without props', () => (<MyComponent />))
  .add('with some props', () => (<MyComponent text="The Comp"/>));

example for Vue:

import { storiesOf } from '@storybook/vue';
import centered from '@storybook/addon-centered';

import MyComponent from '../Component.vue';
storiesOf('MyComponent', module)
  .addDecorator(centered)
  .add('without props', () => ({
    components: { MyComponent },
    template: '<my-component />'
  })
  .add('with some props', () => ({
    components: { MyComponent },
    template: '<my-component text="The Comp"/>'
  });

Also, you can also add this decorator globally

example for React:

import { configure, addDecorator } from '@storybook/react';
import centered from '@storybook/addon-centered';

addDecorator(centered);

configure(function () {
  //...
}, module);

example for Vue:

import { configure, addDecorator } from '@storybook/vue';
import centered from '@storybook/addon-centered';

addDecorator(centered);

configure(function () {
  //...
}, module);

As an extension

1 - Configure the extension

import { configure, setAddon } from '@storybook/react';
import centered from '@storybook/addon-centered';

setAddon({
  addCentered(storyName, storyFn) {
    this.add(storyName, (context) => (
      centered.call(context, storyFn)
    ));
  },
});

configure(function () {
  //...
}, module);

2 - Use it in your story

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

import Component from '../Component';

  .addCentered('without props', () => (<Component />))
