@alialrabi I'm not sure what you expect us to do here. You seem to have added a lot of libs on top of what JHipster has (and you seem to have dev dependencies in-app dependency, which is bad)

Also, you say you have a big app, so obviously the bundle size becomes bigger and slows down the app.

We added lazy loading support in JHipster v5, so you could check that and see how you can reduce your init bundle size.

I suggest you to take this to stack overflow if you need further help as this is not a bug. You cant just add everything and expect great performance as well.
