Next.js: Designed to work closely with React, Next.js picks up where React leaves off. Next.js enables React applications to take advantage of server-side rendering. Though Next.js can create a capable back end, it often serves more of a complementary role, providing React applications with a simple back end.
Meteor: Meteor extends the capabilities of Node.js. It provides access to a proprietary Meteor MongoDB that enables quick data synchronization between Meteor apps and MongoDB storage.
Minimizes the disconnect between the front and back ends. Simplifies the development process and encourages more consistent applications.
Easy to share and reuse code.
Node.js performs exceptionally for many applications compared to alternatives like PHP or Go.
Easy to learn and familiar to most developers.
Supported by a massive community of developers.
Potential performance issues for CPU-intensive applications due to their single-threaded nature.
Must avoid nested callbacks that make code difficult to read and develop.
Possible difficulties working with relational databases.
Node.js APIs frequently change, creating a constant need to rework code.
