What is a web framework and how are frontend and backend related to a web framework? Are these web framework (Django, flask etc..) work at the frontend or at the backend?

CodePudding user response：

Firstly Framework... we can understand this in this way that if there is a person who made bricks. He made the first brick according to measurements like height and width length and he has to make 100 bricks so he made a box of the same height, length, and width instead of doing measurements again and again, and that box is called a framework.
Framework is a collection of tools designed to help create your projects so you don't need to start from scratch.

Similarly, a web framework or web application framework helps build web applications.

There are two types of web-framework:

1. Server-side/Backend

2. Client-side/Frontend

The frontend of a website is the part that is presented to the user, the parts you see and interact with when browsing the web. The backend is the technology behind that presentation layer that makes everything work, i.e. the server, application, and database.

Basically Django is a backend framework but it is both frontend and backend.

But Flask is backend framework.
