"For example, seldom do we see brand new web applications delivered with a traditional, server-based, single-codebase model. Increasingly, they are single-page applications, using APIs and front-end frameworks, such as Angular and React, to tie together functionality." What?

Moreover, this has nothing to do with 'single page apps'.
