As developers, it is important for us to understand how our components are being used in our projects. This can help us identify unused or rarely used components, and make informed decisions about refactoring or removing them. In this blog post, we will explore how to generate usage statistics for components in a Javascript Storybook.

What is Javascript Storybook?

Javascript Storybook is an open-source tool for developing UI components in isolation. It provides a sandbox environment where developers can build, test, and showcase their components. Storybook allows us to view and interact with components in different states and variations, making it a valuable tool for component-driven development.

Setting up Usage Statistics

To generate usage statistics for our components in Javascript Storybook, we can make use of the @storybook/addon-essentials addon. This addon provides various useful features including the ability to track component usage.

To get started, we need to install the @storybook/addon-essentials package:

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

Once installed, we need to add the addon to our Storybook configuration. Open the .storybook/main.js file and update the addons array:

module.exports = {
  // other configuration options
  addons: [
    // other addons
    '@storybook/addon-essentials'
  ],
};

Tracking Component Usage

Now that we have set up the addon, we can start tracking the usage of our components. To do this, open any of your component stories in Storybook and navigate to the “Controls” panel. Here, you will find a new “Usage” tab.

In the “Usage” tab, every interaction with the component will be logged. This includes clicking, input changes, and other events that trigger updates to the component. The usage statistics will be displayed in a table format, showing the number of times each event has occurred.

Analyzing the Usage Data

Once we have collected usage data for our components, we can analyze it to gain insights. We can identify which components are being used the most and which are being used the least. This can help us prioritize our development efforts and make data-driven decisions.

Additionally, we can use the usage statistics to identify components that are not being used at all. These components can be safely removed, reducing the bundle size of our application and improving performance.

Conclusion

Generating usage statistics for components in Javascript Storybook can provide valuable insights into how our components are being used. By using the @storybook/addon-essentials addon, we can easily track component usage and make informed decisions about refactoring or removing components.

Keep in mind that while usage statistics can be helpful, they should not be the sole factor in decision-making. It is important to consider other factors such as business requirements and user feedback.
