Node.js is a popular runtime environment for building server-side applications. It provides a powerful platform for building scalable and efficient web applications. When building web applications using Node.js, developers often use web frameworks to simplify the development process and improve the performance of their applications. One such popular web framework is Express.js.

Express.js is a minimalist web framework that is designed to be flexible and easy to use. It has gained a lot of popularity over the years because of its simplicity and ease of use. However, there are some reasons why you shouldn't use Express.js and why everyone should consider using alternatives like Fastify.

In this blog post, we will discuss why you shouldn't use Express.js and why you should consider using alternatives like Fastify.

Performance

One of the primary reasons why you should consider using alternatives to Express.js is performance. Express.js is a good framework, but it is not designed for high-performance applications. It uses a middleware-based architecture that can slow down your application's performance.

Fastify, on the other hand, is designed for high-performance applications. It uses a plugin-based architecture that provides better performance and scalability. Fastify is built on top of the HTTP module, which makes it faster and more efficient than Express.js.

Scalability

Scalability is another reason why you should consider using alternatives to Express.js. Express.js is not designed for building large-scale applications. It does not provide built-in support for features like clustering and multi-threading, which are essential for building scalable applications.

Fastify, on the other hand, provides built-in support for clustering and multi-threading. It is designed to be scalable and can handle high-traffic applications with ease.

Community and Support

The community and support for a framework are essential when choosing a web framework. Express.js has a large community and a lot of support, which is one of the reasons why it is so popular. However, it is important to note that a large community does not always translate to better support.

Fastify has a smaller community compared to Express.js, but it has a very active and supportive community. The developers behind Fastify are also very active in the community and provide excellent support.

Size

The size of a framework is also an important consideration. Express.js is a relatively large framework that requires a lot of dependencies. This can lead to larger codebases and longer build times.

Fastify, on the other hand, is a lightweight framework that has fewer dependencies. It is designed to be lightweight and efficient, which can lead to faster build times and smaller codebases.

Conclusion

In conclusion, while Express.js is a good framework, there are some reasons why you should consider using alternatives like Fastify. Fastify is designed for high-performance and scalability, has an active and supportive community, and is lightweight and efficient. When building high-performance and scalable applications, it is essential to choose a framework that can handle the load. Fastify is one such framework that should be considered.
