Storybook Add-ons Architecture

1. Introduction

Storybook add-ons extend the functionality of Storybook by allowing developers to customize the development environment and enhance the user experience. Understanding the architecture of add-ons is crucial for creating efficient and effective tools.

2. Key Concepts

2.1 What are Add-ons?

    // Add-on logic here
});

Define your UI components that will be rendered in the Storybook interface.
