We will be building a user authentication in a single page application with Node, React, Redux and Koa combined with Passport. We will implement local authentication, where users can log in using an email and passport, and authentication with Facebook, which can be used with other social networks and OAuth providers.
Build micro frontends that coexist and can each be written with their own framework. This allows you to: Use multiple frameworks on the same page without refreshing the page (React, AngularJS, Angular, Ember, or whatever you're using); Write code using a new framework, without rewriting your existing app; Lazy load code for improved initial load time.
