concept Next.js in category isomorphic web applications

This is an excerpt from Manning's book Isomorphic Web Applications: Universal Development with React.
If you’re looking for an all-in-one solution that uses React, Next.js is a strong option. Isomorphic by default, Next.js uses a convention-driven approach to building a React app. Even if you decide not to use Next.js in production, you may find it a good tool for building isomorphic prototypes or proofs of concept (pocs). It could aid you in selling the idea of isomorphic to your team or boss.
Figure 12.11 walks through the isomorphic flow as implemented by Next.js. Next.js is server rendered by default, so you don’t have to configure anything!
Overall, Next.js provides a great solution if you want to try something quickly or if you have a simple app with just a few pages. For complex apps with dynamic routing, Next.js requires more time investment to get up and running.
