In today’s digital landscape, accessibility is an integral part of creating inclusive and user-friendly web applications. It is essential for developers to ensure that their code is accessible to all users, including those with disabilities. In this blog post, we will explore how we can incorporate accessibility best practices in Javascript Storybook, a popular UI development environment.

Why is Accessibility Important?

Accessibility ensures that people with disabilities or impairments can access and interact with web applications just like anyone else. By making our code accessible, we can provide a seamless user experience for all users, regardless of their abilities. Furthermore, accessible applications are integral in adhering to legal requirements and inclusive development practices.

Getting Started with Javascript Storybook

First, let’s start by setting up a basic Storybook project. Use the following commands in your command line interface:

npx create-react-app my-app
cd my-app
npx -p @storybook/cli sb init

Once your project is set up, you will have a .storybook directory in your project’s root folder. Inside this directory, create a new file called preview.js. This file will serve as the entry point for configuring accessibility in Storybook.

Configuring Accessibility

To incorporate accessibility best practices in Storybook, we will be using the @storybook/addon-a11y package. Install this package by running the following command:

npm install @storybook/addon-a11y --save-dev

Once installed, open preview.js and add the following code:

import { addons } from '@storybook/addons';
import { configureA11y } from '@storybook/addon-a11y';

addons.setConfig({
  ...

  addons: [
    ...,

    {
      name: '@storybook/addon-a11y',
      options: {
        // Configure additional accessibility options here
      },
    },
  ],
});

configureA11y({
  // Configure accessibility checks here
});

You can customize the accessibility checks based on your requirements. For example, you can enable or disable specific rules, configure the violation levels, and set the locale.

Running Accessibility Checks

To run accessibility checks for your Storybook components, use the following command:

npx start-storybook -p 6006 -s public

This command launches your Storybook server and runs the accessibility checks in the browser. You can navigate to localhost:6006 to access your Storybook UI.

You will see a new panel titled Accessibility in your Storybook UI. This panel will display any accessibility violations found in your components. By addressing these violations, you can improve the accessibility of your code.

Conclusion

Incorporating accessibility best practices in Javascript Storybook is essential to create more inclusive web applications. By following the steps outlined in this blog post, you can seamlessly integrate accessibility checks into your Storybook workflow. Remember, accessibility is not optional; it is a fundamental aspect of web development that fosters equal access and usability for all users.
