…the data-main=“app” …the “app” should be the path to the app.js without extension. If this app.js is not in the root(like with the framework like Symfony), then you have to define its path here…like data-main="/somefolder/otherfolder/app".
Hope your project is (or went) well! I’m using Slim, which is somewhat similar to Symfony. Do you have any advice on putting this together? I have already created all of the routes using Slim, so now I’m having to back track because I want to use Webix Jet.
