Product tours are interactive guides within a product's user interface designed to simplify complex user experiences and aid in user onboarding by providing inline, self-explanatory tips. These tours are particularly beneficial for B2B products, reducing the workload of customer support teams by addressing frequently asked questions. Popular platforms like Slack, Trello, and Asana utilize product tours to familiarize users with their interfaces and highlight new updates. Among the React libraries available for creating product tours are React Tour and React Joyride, each offering distinct features and varying levels of customization. React Tour is known for its straightforward setup and attractive UI but lacks flexibility, while React Joyride provides more customization options and exposes events for user-defined actions, despite having a less intuitive API. Building a customized product tour can involve a combination of existing libraries and custom React components, focusing on challenges such as targeting UI elements and managing responsive popover components.
