ExpressJS vs Fastify: What are the differences?

Developers describe ExpressJS as "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. On the other hand, Fastify is detailed as "Fast and low overhead web framework, for Node.js". Fastify is a web framework highly focused on speed and low overhead. It is inspired from Hapi and Express and as far as we know, it is one of the fastest web frameworks in town. Use Fastify can increase your throughput up to 100%.

ExpressJS and Fastify 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, Fastify provides the following key features:

  • 100% asynchronous: all the core is implemented with asynchronous code, in this way not even a millisecond is wasted.
  • Highly performant: as far as we know, Fastify is one of the fastest web frameworks in town, depending on the code complexity we can serve up to 20000 request per second.
  • Extendible: Fastify is fully extensible via its hooks, plugins and decorators.

ExpressJS and Fastify are both open source tools. ExpressJS with 44.6K GitHub stars and 7.48K forks on GitHub appears to be more popular than Fastify with 11.2K GitHub stars and 690 GitHub forks.

According to the StackShare community, ExpressJS has a broader approval, being mentioned in 854 company stacks & 788 developers stacks; compared to Fastify, which is listed in 5 company stacks and 7 developer stacks.

    What are some alternatives to ExpressJS and Fastify?
    Koa
    Koa aims to be a smaller, more expressive, and more robust foundation for web applications and APIs. Through leveraging generators Koa allows you to ditch callbacks and greatly increase error-handling. Koa does not bundle any middleware.
    React
    Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project.
    Flask
    Flask is intended for getting started very quickly and was developed with best intentions in mind.
    Django
    Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design.
    Go
    Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.
