What is Flask?

A well-known and unique Python-based web framework, Flask, which was built on minimalist principles, is lightweight. It adheres to the philosophy of little frameworks that provide only the essentials for web development such as routing, templating, and request handling. This makes it flexible and gives developers an opportunity to customize their applications with a variety of extensions through core functionalities. The popular extensions include ORM for interacting with databases, user authentication, etc....

What is Express.js?

Express.js is a lean web framework built on top of Node.js, which is a powerful JavaScript runtime environment. Contrary to Flask’s microframework approach, Express.js has more solid foundation for web development. It offers basic features such as routing, middleware support, and HTTP utility methods. However, Express.js encourages developers to use middleware for additional functionalities. Middleware helps developers in writing modular code to promote code reusability. This in turn enables the developers to create complicated and scalable web applications....
