Error parsing descriptor string in production environment

Hi

First of all. Stimulus is great - thanks for sharing this with us. I’ve spent the day getting it into my Phoenix app which already uses turbolinks. It works great in my development environment 🎉.

After finishing up the intended work, I decided to ship it to our production environment. But it seems like the production build fails to setup the actions & targets. I assume it has something to do with minification of the javascript. 😢

I can’t find any information in the docs about this issue. I’m not using webpack. The stimulus instance is starting, and the controllers are connected properly. But the actions cannot be parsed.

Here’s an output of the stacktrace in Chrome.

Error parsing descriptor string "click->card-show#editDescription" for element

What to do? 😄 ❓

just to clarify in case this happens to anyone, just add the following to your brunch config

plugins : {
   uglify: {
      mangle: false
    }
}

@javan Thank you for pointing me in the right direction. It works now.
