Django vs Tornado: What are the differences?

What is Django? The Web framework for perfectionists with deadlines. Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design.

What is Tornado? A Python web framework and asynchronous networking library, originally developed at FriendFeed. By using non-blocking network I/O, Tornado can scale to tens of thousands of open connections, making it ideal for long polling, WebSockets, and other applications that require a long-lived connection to each user.

Django and Tornado can be primarily classified as "Frameworks (Full Stack)" tools.

"Rapid development" is the primary reason why developers consider Django over the competitors, whereas "Open source" was stated as the key factor in picking Tornado.

Django and Tornado are both open source tools. It seems that Django with 42.3K GitHub stars and 18.2K forks on GitHub has more adoption than Tornado with 17.9K GitHub stars and 4.97K GitHub forks.

According to the StackShare community, Django has a broader approval, being mentioned in 979 company stacks & 882 developers stacks; compared to Tornado, which is listed in 69 company stacks and 16 developer stacks.

Around the time of their Series A, Pinterest’s stack included Python and Django, with Tornado and Node.js as web servers. Memcached / Membase and Redis handled caching, with RabbitMQ handling queueing. Nginx, HAproxy and Varnish managed static-delivery and load-balancing, with persistent data storage handled by MySQL.

In late 2015, following the Series G, Pinterest began migrating their web experience to React, primarily because they “found React rendered faster than our previous template engine, had fewer obstacles to iterating on features and had a large developer community.”

The legacy setup consistent of Django, Python and Jinja on the backend, with Nunjucks handling template rendering on the client side. They wanted to move to React for handling template rendering across the board, but if they “switched the client-side rendering engine from Nunjucks to React, [they’d] also have to switch [their] server-side rendering, so they could share the same template syntax.”

They decided on an iterative approach that consolidated a single template rendering engine between client and server, since “If the server could interpret JavaScript, and use Nunjucks to render templates and share our client-side code, we could then move forward with an iterative migration to React.” The team decided to stand up a Node process, behind Nginx, and interpret JavaScript server-side.

Now, when a user agent makes a request, a latent module render requests that it needs data via an API call. Concurrently, a separate network call is made “to a co-located Node process to render the template as far as it can go with the data that it has.”

Node then responds with rendered templates, and along with a “holes” array to indicate what data was still needed to complete the render. Finally, the Python webapp makes an API call to fetch the remaining data, and each module is sent back to Node as completely independent module requests/in parallel/.

With this framework in place, Pinterest developers are in the process of replacing Nunjucks code with React components throughout the codebase.

Since 2011 our frontend was in Django monolith. However, in 2016 we decide to separate #Frontend from Django for independent development and created the custom isomorphic app based on Node.js and React. Now we realized that not need all abilities of the server, and it is sufficient to generate a static site. Gatsby is suitable for our purposes. We can generate HTML from markdown and React views very simply. So, we are updating our frontend to Gatsby now, and maybe we will use Netlify for deployment soon. This will speed up the delivery of new features to production.

Django REST framework

Zulip has been powered by Django since the very early days of its development with Django 1.4, back in 2012. As a reasonably mature web application with significant scale, we're at the stage in many companies' development where one starts to rip out more and more of the web framework to optimize things or just make them work the way we want. (E.g. while I was at Dropbox in early 2016, we discovered we only had about 600 lines of code left from the original Pylons framework that actually ran).

One of the things that has been really fantastic about Django is that we're still happily using it for the vast majority of code in the project, and every time Django comes out with a new release, I read the changelog and get excited about several improvements that actually make my life better. While Django has made some design decisions that I don't agree with (e.g. I'm not a fan of Django REST framework, and think it makes life more difficult), Django also makes it easy to do your own thing, which we've done to great effect (see the linked article for details on our has_request_variables framework).

Overall I think we've gotten a ton of value out of Python and Django and would recommend it to anyone starting a new full-featured web application project today.

Django or NodeJS? Hi, I’m thinking about which software I should use for my web-app. What about Node.js or Django for the back-end? I want to create an online preparation course for the final school exams in my country. At the beginning for maths. The course should contain tutorials and a lot of exercises of different types. E.g. multiple choice, user text/number input and drawing tasks. The exercises should change (different levels) with the learning progress. Wrong questions should asked again with different numbers. I also want a score system and statistics. So far, I have got only limited web development skills. (some HTML, CSS, Bootstrap and Wordpress). I don’t know JavaScript or Python.

Possible pros for Python / Django: - easy syntax, easier to learn for me as a beginner - fast development, earlier release - libraries for mathematical and scientific computation

Possible pros for JavaScript / Node.js: - great performance, better choice for real time applications: user should get the answer for a question quickly

Which software would you use in my case? Are my arguments for Python/NodeJS right? Which kind of database would you use?

Thank you for your answer!

I really love Django because it is really fast to create a web application from scratch and it has a lot a facilities like the ORM or the Admin module ! The Python language is really easy to read and powerful, that's why I prefer Django over Symfony.

I use Django at work to make tools for the technicians but I also use it for me to build my personal website which I host on PythonAnywhere.

I've been using Django for quite a long time and in my opinion I would never switch from it. My company is currently using Django with REST framework and a part in GraphQL using Graphene. On the frontend we use Next.js and so far everything has been running quite good. I've found limitations but manage to solve it.

As someone mentioned before, if you are comfortable with Django, don't switch. There's no need since with django you can basically achieve anything. Of course this will depend on the project you want to build, but the scalability and flexibility django can offer it's just out of this world. (Don't want to sound like a fan boy haha but it really is).

Django takes the hassle out of building an enterprise web application using Python.

  • admin app for administration
  • ORM for deploying against different database vendors
  • social auth package for authentication with enterprise IdP
  • guardian package for authorization

Our backend was written in Django. We took advantage of the ready-to-go admin interface as a go-to solution for the client to be able to authorize his users, as well as other functionality, while most of the work was done through the Django Rest Framework.

Hands down the best Python web framework I've used. Very easy to extend and add apps and go from 0 to full project quickly and painlessly. I built a fully authenticated project with a single endpoint in less than 30 minutes.

SpreadServe's RealTimeWebServer is built in Tornado. Spreadsheets loaded into SpreadServeEngine instances are projected into browsers using Tornado. Server side recalcs are pushed to the browser using web sockets.

정말 편리하고 많은것을 알아서 제공해 주는 프레임워크 이다. 책의 예제만 진행해서 많이 써보지는 못했지만, 쉽게 쉽게 웹을 개발 할 수 있는 점이 매력적 이다. 게다가 orm 이 기본으로 내장 되어 있고 db 도 sqlite 가 기본으로 되어있어. 그냥 django 만 설치하면 바로 웹개발이 가능하다.

setup an api for a client with tornado backend. incredibly fast and lightweight. unfortunately breaks down when using third party libraries which block internally.

django는 저의 무기입니다.

django 이외에 flask로 간단한 restful api를 만들면서 느낀점은 framework 보다 언어가 중요하다는것을 알았고 django가 얼마나 큰 framework인지 알게되었습니다.

저는 signal 사용을 좋아합니다.

Tornado with Async/Await coroutines provided in Python 3.5 make up for an excellent stack for a micro-service.
