Nodejs Express vs Django Choosing the best suitable backend component for given requirements

Question

I'm trying to build a software architecture for my web development. The main requirements of the website are as follows:

• visualize real-time data
• carry out machine learning analysis
• Report visualization information via Email or SMS

The concept for such an web application consists of a database, a backend and a frontend component. I have already selected a time series database.

Despite my research, I cannot determine which backend component best meets the requirements: Nodejs + Expressjs or Django. My programming knowledge in Javascript and Python is on the same level.

Why Node:

• its Single Threaded Event Loop Model for real-time web applications
• same programming language for selecting a javascript framework on the frontend-side (but python for machine learning analysis)
• More flexibility than Django due to its MTV pattern
• (usually) less execution time than python-Code

Why Django:

• Django Channels for real-time web applications
• python language in backend, frontend and for data analysis
• quicker development process because of the language simplicity
• more secure due to its build-in security tools

Question: Are there any other technical arguments why I should consider choosing Nodejs or Django or any arguments for not choosing one of them?

Answer 1

Yes, it's true that Node.js is faster than Django, but how much faster? Django is also incredibly strong and versatile in the sense that you have to write less boilerplate code and offers you many solutions out of the box like an admin panel, authentication, and many more. Does it really matter?
Celery-related concepts are also present in Django and are applied to background operations like email sending. a potential replacement for nodejs threading.

While django has channels, nodejs has websockets.

Both support machine learning, while nodejs additionally supports Tensorflow and includes many more libraries.

You should, in my view, choose one of the more established web frameworks, such as Django, Laravel, Rails, etc. This is because Node.js web frameworks are relatively new to the market, whereas Django has probably been there for more than 20 years, and the same is true of Laravel, etc. Express uses a lot of boilerplate code, and nestjs is still a fairly new framework.

I hope my advice will be helpful. Personally, I began with Node.js and am currently using Django. Although I think nodejs is great, if you need to write anything quickly, nodejs is not the best option.
