[SOLVED] Why this web application built with Clojure, ClojureSript, Figwheel, Lein is not been updated on the browser after editions on the source code?

Why this web application built with Clojure, ClojureSript, Figwheel, Lein is not been updated on the browser after editions on the source code?

I am watching a course/tutorial from Eric Normand on front-end. The course is a paid private service.

However, he is using a public repo on GitHub, this one.

After cloning and executing lein fig-dev, the project seems to have been succesfully built:

In the cljs.user ns, controls can be called without ns ie. (conns) instead of (figwheel.repl/conns)

cljs.user=> (js/alert "hello")
nil

This is all my log (question was asked as comment below).

The browser starts (I am using Brave) and the application seems to be succesfully loaded on http://localhost:3449//.

I have a REPL working and I can even do alerts like that happen as events on the browser at localhost:

cljs.user=> (js/alert "hello")
nil

Ok. The only problem is when I edit the sorce code as he does on the videos. In his case, the changes make effect on the browser. On my case, they do not. Nothing happens.

I can only see changes if I rebuilt everything from scratch.

In other projects, I managed to see the changes happening live, but I was using shadow-cljs there.

How do I fix this?

Obs.: I am using Macbook M1, macOS Monterey 12.5.1

Solution

Thanks to @SearCorfield, I managed to solve the problem.

Also, Eric Normand (the creator of the course and author of the repository) has just updated the project.clj file to have [com.bhauman/figwheel-main "0.2.18"]. It now works smoothly!
