The current documentation is an indiscriminate mix of error-riddled Classic and Modern using CMD.
The CMD MyApp with view/main is very different from npm MyExtGenApp with view/home (that looks like spaghetti code)
https://docs.sencha.com/extjs/7.0.0/...hitecture.html
does not help to understand MyExtGenApp, even if it was updated to 7.0.0.97
I don't mind paying for an error-free online self-paced course of pdfs/htmls and fiddles/code that go from hello-world to a routed npm app with aws amplify and appsync.
Anyone making a Modern Ext JS 7 tutorial?
