I doubt you can find a good doc on such a specific subject. That being said, if you split the problem into its constituents, it becomes trivial to research: 1. How to handle mouse events on a canvas in JS 2. How to work with mouse events in React 3. How to translate React code to Reagent I haven't checked so might potentially be wrong somewhere, but as an example for a mouse click: 1. Probably by handling the click event on the canvas DOM node 2. Probably via the onClick property passed to 3. Certainly by using :on-click or :onClick as a property for [:canvas ...].

You can extend that logic to absolutely anything. Good source for JS-related docs is the MDN website. As for React/Reagent/re-frame - their own docs are great as a reference and also a learning material.

That's plenty to start with, thanks 🙂
