The article explains how to implement tooltip functionality in Phoenix LiveView applications using the tippy.js library. tippy.js is a lightweight and versatile tooltip library that requires careful integration with LiveView to update tooltip content and styling dynamically. The author outlines the installation process, configuration, and usage of client-side hooks to ensure that any changes made to tooltip attributes in LiveView are accurately reflected in the tippy.js tooltip instance. A sample HTML button element illustrates the integration, along with detailed explanations of the LiveView hook's lifecycle methods—mounted, updated, and destroyed—to manage the lifecycle of the tooltips effectively. The conclusion acknowledges alternatives to tippy.js, such as Alpine.js plugins and Floating UI, while emphasizing the importance of finding solutions that align with the needs of specific projects.
