Edenspiekermann Storybook Starter

This repository can be used alongside React projects to develop and documented all shared UI components in a separate environment.

How to install

If not already set up, yarn.

Then navigate to the folder you cloned this project into and enter:

yarn 

This will install all necessary dependencies.

How to develop

Clone this repository and start adding components. On the repository for the web site that will include the components, add this repository as a dependency in your package.json.

If you don't publish your component library via npm, you can link to the Git Repository directly. Both ways will work, as we don't have a prepublish step but rather build the dist folder on the target machine after installing this package as dependency.

Adding a new Component

All components should be placed in the folder /components in their own subfolder.

A component typically consists of:

• A component-name.jsx file containing the React component as a default export. Be sure to include prop types and default props for the component.
• A component-name.stories.js file containing the stories for this component. A story reflects a variant of the component that is documented on an individual page in Storybook.
• A component-name.test.js file containing all unit tests for the component. (Note: It is not necessary to write snapshots tests as they will be created automatically from your stories via the StoryShots plugin.)
• A README.md containing the documentation for this component in Markdown format
• A component-name.scss file containg all styles for the components
• A file containing the snapshots generated from the stories of this component. This will be taken care of automatically and placed in a separate folder so you don't need to care about it.

(Replace component-name with the name of your component written in kebab case accordingly)

Please ensure to follow these naming conventions as all related build processes are set up to recognize files following the naming scheme. If you did successfully, a documentation page for the component will show up when you run Storybook.

In order to import your React component easily in other repositories, add it as named export to the components/index.js file. Optionally, you can also add an index.js file in your component subfolder.

In your target application, you can then import the component like this:

import { Button } from 'edenspiekermann-storybook-starter'; // replace the name of your repository accordingly

Available Tasks

• yarn storybook: run local server with the Storybook component library
• yarn build: transpiles component library to ./dist to be exported via NPM
• yarn build:storybook: build static production version of component library to ./build
• yarn build:sassdoc: generate SCSS documentation to ./build/sassdoc
• yarn build:docs: lints and tests components and then builds Storybook and Sassdoc pages to ./build
• yarn lint: lint JS code
• yarn lint:styles: lint SCSS code
• yarn test: run unit tests and show coverage
• yarn coverage: run unit tests and show coverage
• yarn update-snapshots: update jest snapshots in case you intentionally changed the markup of your components

Pre-commit Hooks

When attempting to commit files in this repository, some tasks will automatically run to ensure a consistently high level of code quality:

• JavaScript files (.js and .jsx):

  • runs eslint and automatically fixes auto-fixable issues (see related JS guidelines here)
  • runs prettier and auto-formats your code (see what it does here)
  • runs all unit tests concerning the committed files with jest

• SASS files (.scss):

  • runs stylelint and automatically fixes auto-fixable issues (see related SASS guidelines here)

If any of the tasks fail (which means your code does not lint or unit tests are failing), your commit will be aborted.

Modern JavaScript Transpilation

You can use any modern JavaScript in your components that can be automatically transpiled. The Babel configuration is set up to recognize ES2017 and beyond. Be aware that if you use non-transpilable modern JavaScript functions like Object.entries or similiar, you need to manually or automatically include a polyfill in your target repository so that browsers can understand your code.

Deploying the docs on Netlify

Often, it is useful to host the component library documentation online, so that other people can have access to it without checking out the project and running it locally.

For this case, a Netlify config is already set up, so that you only need to connect your git repository to Netlify. The docs will be built automatically on every pushed commit. Your the docs will be available here:

• Storybook: https://your-project-name.netlify.com/
• SassDoc: https://your-project-name.netlify.com/sassdoc

(replace "your-project-name" with the name of your Netlify project accordingly)
