How do you architect your project to cater to changes in frameworks and libraries?

For example, when react-router moved to v4, there was a significant paradigm shift in the way react-router worked. If your application was heavily invested in react-router, migrating to v4 was a painful experience.

PS - I don't mean to call out react-router here. I ❤️ v4 and the work that they are doing. Just highlighting a scenario that I've run into. 😄
