Easily Add Product Tours with Hopscotch Framework
Hopscotch is a framework to make it easy for developers to add product tours to their pages. Hopscotch accepts a tour JSON object as input and provides an API for the developer to control rendering the tour display and managing the tour progress.
Hopscotch has several events to which you can assign callbacks. These events include start, end, next, prev, show, close, error. For the next, prev, and show events, you can assign callbacks within step definitions as well as in the tour itself.
