ui-router

Nearly all of these complaints about SPAs have to do with navigation. It's true, when you make a SPA, you need to factor in routing. That's part of the design decision. When you use a SPA framework like Angular, the typical go to is to use Angular UI Router (https://github.com/angular-ui/ui-router) to manage your page and state transitions within those pages. By default, you get back button support, it's highly customizable and configurable and it's not difficult to manage at all.

If you're looking for a monolithic solution, Meteor may not be for you. Check out Wakanda and Servoy. Delegating quasi-core parts of the platform to 3rd party libraries is quite common. For example, the preferred routing package for Angular, ui-router (https://github.com/angular-ui/ui-router) was born four years after the release of Angular, and for DOM state preservation, the ui-router-extras (https://github.com/christopherthielen/ui-router-extras) addon is required.
