I believe nextjs uses Serverless Functions, while express requires an always running server. Performance wise I think an always running server would win as it its always ready to handle requests, but if the Serverless function is on a good hosting platform that handles the function calls nicely without many cold starts then it wouldn't make much difference performance wise. A good question would be if nextjs Serverless Functions on Vercel are better than lambda functions on AWS. [edit]: u/CreativityExplorer rightly pointed out that Vercel uses aws lambda to deploy the Serverless Functions so its almost the same thing! Answer from abhinayx on reddit.com

Next.js server instead of express.js
I’m learning Next.js and I’m making an example signup and login page with next-auth and mongoDB, I’m struggling with that, I think doing it with express.js, so my question is to decide which technology is more suitable. Express Server or Next.js? More on forum.freecodecamp.org

Firebase Auth using - next js vs express and cloud functions
Have you looked at https://next-auth.js.org/ ? They provide a Firebase adapter for easier integration. Keep in mind that Vercel has various hard limits based on fair-use. If these limits are a concern for you then you may want to offload some of the calls to other parties (e.g. cloud functions hosted elsewhere). More on reddit.com

People also ask

Can I use Next.js and Express.js together?
Absolutely! If your app needs a React frontend (Next.js) and a separate, powerful backend (Express.js), they work well together. You can run Express.js for custom API logic while using Next.js for rendering your UI.

Does Next.js use Express.js under the hood?
Nope! Next.js doesn’t rely on Express.js, but you can use them together. Some developers set up an Express.js server to handle routing, authentication, or other backend tasks alongside Next.js.

Which one is better for SEO: Next.js or Express.js?
Next.js, no question. With server-side rendering (SSR) and static site generation (SSG), search engines love Next.js sites. Express.js doesn’t handle frontend rendering, so it’s not an SEO tool.

Express.js vs Next.js: What is the difference?

A little bit about each framework:

1) What is Express.js?

Express.js, or simply Express, is a backend web development framework for Node.js. It is intended for the development of web applications and APIs. It’s been dubbed Node.js’ de facto standard server framework.

This answer explains what Express is in greater detail.

2) What is Next.js?

Next.js is the React framework for production.

Let's debunk this sentence:

  • "Framework": It has a lot of built-in features (e.g file-routing which replaces react-router-dom) that help you solve common problems.
  • "For React": Next.js just enhances your React apps and adds more features to them.
  • "For Production": There are certain problems that you will need to solve for almost all production-ready React apps. Next.js solves those for you.

Next.js gives you the best developer experience with all the features you need for production: hybrid static & server rendering, TypeScript support, smart bundling, route pre-fetching, and more. No config is needed.

Express.js vs Next.js features

Some Express.js features are:

  • Robust routing
  • HTTP helpers (redirection, caching, etc)
  • View system supporting 14+ template engines

Next.js provides the following key features:

  • Zero setup. Use the filesystem as an API ( You do not need Express to build a full-stack application)
  • Server-Side rendering (SSR)
  • Static site generation (SSG)
  • Single-Page application (SPA)
  • Development of faster applications
  • Optimization of pages
  • SEO websites
  • Automatic code splitting

Conclusion

Express.js is a backend framework for building APIs whereas Next.js is a full stack framework that builds upon React to improve the SEO, development experience, and performance of your project. One of these features IS a built-in API routing system that could replace Express.js.

It all depends on the case you have and your personal preference. If you are building a private page (admin panel that can only be accessed with authentication) that does not need to be found by search engines, you do not need Next.js and will need Express.js. If you are building a public website (e.g. e-commerce website) and you are using Next.js for SEO optimization, you could replace Express.js with it.


TL;DR

You can replace an Express API with Next.js's API routing system but that only makes sense if you're building a full-stack React project. If it's a standalone API, using Next.js to replace just that API doesn't make any sense.

Express is a general purpose tool for building HTTP servers in Node.js.

Next.JS is a tool for building an HTTP server specifically to perform server-side rendering of a React application (and which comes with some general purpose features so you can do things like build a server-side API for that React application to access in the same package).
