@storybook/addon-viewport offers a streamlined approach to responsive design testing directly within Storybook. The latest versions, 6.4.22 and the previous 6.4.21, enable developers using React to effortlessly simulate various screen sizes and orientations, enhancing the accuracy of component rendering and usability across devices. This addon's core functionality revolves around adjusting Storybook's viewport, allowing to test how components adapt to different screen dimensions.
The key distinction between versions lies primarily in internal dependency alignment within the Storybook ecosystem. Version 6.4.22 updates dependencies such as @storybook/api, @storybook/addons, @storybook/theming, @storybook/components, @storybook/core-events, and @storybook/client-logger to version 6.4.22, ensuring synchronization and compatibility with other Storybook addons and core functionalities. Version 6.4.21 aligns these same dependencies to 6.4.21. While the core functionality remains consistent between these patch releases, developers should opt for the latest version (6.4.22) to benefit from the most up-to-date fixes and potential performance improvements across the Storybook platform. Both versions are compatible with React versions 16.8.0 and 17.0.0, ensuring wide compatibility. By simulating different viewports, this addon aids developers in building responsive UI components, delivering a better user experience across diverse devices.
