Developed a disable-interactions feature for the storybookjs/storybook addon, introducing a type-safe disable state parameter to control user interactions within Storybook. The implementation involved refactoring the disable logic into a reusable utility function, which improved maintainability and facilitated comprehensive unit testing. Leveraging React and TypeScript, the work addressed TypeScript errors and ensured robust test coverage to reduce the risk of user experience regressions when interactions are disabled. Code formatting was enhanced using Prettier, contributing to overall code quality. This focused engineering effort strengthened the reliability of the addon and streamlined future development by making the disable logic more modular.
