Express as the most popular Node.js framework

There are a multitude of frameworks that Node.js brings to the table for developers to implement scalable and agile mobile & web applications. While different frameworks are apt for certain specific use-cases, Express is the most popular and frequently used frameworks by the developer community to implement both web as well as mobile applications. Express is the first-choice framework for applications built on top of Node.js. The framework provides a collection of routing libraries which forms a dynamic layer on the web application allowing developers to include custom features on top of the existing Node.js framework.

In addition to the sophisticated features, Express also introduces more than 14 template engines which can be referenced by developers to give shape to their application at a fast pace. Express is also a preferred choice for developers for designing API (Application Programming Interface) based applications as well as the framework has inbuilt HTTP utility functions & features enabling quick & robust design of APIs.

Why is Express the most preferred framework amongst other top Node.js frameworks?

  1. Performance — Performance is one of the most preferred factors basis which developers select the framework of their choice. Express being a minimalist framework has a thin layer of customization over the existing Node.js features. This means that the inherent performance optimization (in terms of input/output operations, event routing etc.) of Node.js is not compromised.
  2. Simplicity — The ‘Express’ framework is not attached to any pre-defined design patterns such as the MVC architecture or the MVP framework etc. Hence, designers have the leeway to orchestrate their own design patterns which would suit the particular application.
  3. Rich collection of templates — Designers and developers generally prefer frameworks with an exhaustive collection of templates as these are readily usable and gives a concrete shape to their application without them having to code every bit of it. There are multiple options provided by the express generator which can be leveraged by developers as per the need of the situation.

How to choose the best framework for a particular project/application?

  1. Performance & scalability
  2. Options for easy customization
  3. Availability of rich collected of pre-defined templates & modules
  4. Available documentation & community

Taking all of these parameters into consideration; Express proves to provide a holistic framework to developers and designers with an optimal mix of all the aforementioned features.
