Top 10 Backend Frameworks in 2022

A web app consists of two layers - frontend and backend. Frontend refers to the presentational layer which is visible to the end users. It includes structure, style and behaviour of different elements on the screen. Backend, also known as server-side layer, refers to the layer which runs on the server and is not visible to the users, and holds the data required by the frontend. It includes the server-side logic of the web app, like APIs, app security, authentication and authorization.

In this blog, I am going to talk about the Backend layer. The most common languages used for building backend are:

• Python
• Java
• Rails
• PHP
• C#
• Go
• JavaScript

There are a bunch of frameworks built on the top of these languages which make backend development easier and smoother. I will be talking about some of the most popular frameworks used worldwide. So, without any delay, let's jump right into it!

5. Spring
6. ASP.NET Core
7. Flask

Final Thoughts

There are many backend frameworks other than those mentioned above. No framework is the best. It, really, depends on the project you are working. For example, if you want to deploy a Machine Learning model, I would recommend using microframework like Flask or FastAPI for it. Likewise, if you want to build an ERP portal, then I would recommend using Django or Ruby on Rails or any other full stack framework of your choice.

Which web framework do you use? Do let me know in the comments.
