ExpressJS vs FastAPI: What are the differences?

What is ExpressJS? Sinatra inspired web development framework for node.js -- insanely fast, flexible, and simple. Express is a minimal and flexible node.js web application framework, providing a robust set of features for building single and multi-page, and hybrid web applications.

What is FastAPI? A high performance, easy to learn, fast to code, ready for production web framework. It is a modern, fast (high-performance), web framework for building APIs with Python 3.6+ based on standard Python type hints.

ExpressJS and FastAPI can be categorized as "Microframeworks (Backend)" tools.

Some of the features offered by ExpressJS are:

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

On the other hand, FastAPI provides the following key features:

  • Very high performance, on par with NodeJS and Go
  • Increase the speed to develop features by about 200% to 300%
  • Reduce about 40% of human (developer) induced errors

ExpressJS is an open source tool with 52.8K GitHub stars and 8.89K GitHub forks. Here's a link to ExpressJS's open source repository on GitHub.

Twitter, Atolye15, and Freetrade are some of the popular companies that use ExpressJS, whereas FastAPI is used by primer.io, Sendcloud, and OnlineDoctor. ExpressJS has a broader approval, being mentioned in 1621 company stacks & 14728 developers stacks; compared to FastAPI, which is listed in 14 company stacks and 41 developer stacks.
