Storybook for Mithril

You may have tried to use our quick start guide to setup your project for Storybook. If you want to set up Storybook manually, this is the guide for you.

This will also help you to understand how Storybook works.

Starter Guide Mithril

Storybook has its own Webpack setup and a dev server.

In this guide, we will set up Storybook for your Mithril project.

Table of contents

Add @storybook/mithril

First of all, you need to add @storybook/mithril to your project. To do that, simply run:

npm i --save-dev @storybook/mithril

Add mithril and babel-core

Make sure that you have mithril and babel-core in your dependencies as well because we list these as a peerDependency:

npm i --save mithril
npm i --save-dev babel-core

Then add the following NPM script to your package json in order to start the storybook later in this guide:

{
  "scripts": {
    "storybook": "start-storybook -p 9001 -c .storybook"
  }
}

Create the config file

Storybook can be configured in several different ways. That’s why we need a config directory. We've added a -c option to the above NPM script mentioning .storybook as the config directory.

For the basic Storybook configuration file, you don't need to do much, but simply tell Storybook where to find stories.

To do that, simply create a file at .storybook/config.js with the following content:

import { configure } from '@storybook/mithril';

function loadStories() {
  require('../stories/index.js');
  // You can require as many stories as you need.
}

configure(loadStories, module);

That'll load stories in ../stories/index.js.

Write your stories

Now you can write some stories inside the ../stories/index.js file, like this:

/** @jsx m */

import m from 'mithril';

import { storiesOf } from '@storybook/mithril';
import { action } from '@storybook/addon-actions';
import Button from '../components/Button';

storiesOf('Button', module)
  .add('with text', () => ({
    view: () => <Button onclick={action('clicked')}>Hello Button</Button>
  }))
  .add('with some emoji', () => ({
  	view: () => <Button onclick={action('clicked')}><span role="img" aria-label="so cool">😀 😎 👍 💯</span></Button>
  }));

Story is a single state of your component. In the above case, there are two stories for the native button component:

  1. with text
  2. with some emoji

Run your Storybook

Now everything is ready. Simply run your storybook with:

npm run storybook

Now you can change components and write stories whenever you need to.
