Express.js vs web2py

Setting up a new Express project is very easy. It consists of installing a handful of libraries through NPM run a single npm install and everything is ready to go.

Express' extremely powerful routing API allows developers to do tasks ranging from building a REST API to building the routes for a simple web app and then take it to the next level by using route parameters and query strings.

With a little learning curve, it is a good choice for new NodeJS developers to get started quickly. Express boasts great, thorough documentation.

Node.js Foundation

Announcement here

The Node.js Foundation is a Collaborative Project at The Linux Foundation. Linux Foundation Collaborative Projects are independently funded software projects that harness the power of collaborative development to fuel innovation across industries and ecosystems.

Being a somewhat old Node.js web app framework and being one of the most widely used frameworks, Express.js has matured quite a lot during all that time. It's more stable than its competitors and a huge community backing it.

Express takes advantage of Node's NPM to distribute and install countless plugins made by third parties which solve almost anything a developer would want to do with Express.

It's by far the most popular framework for node.

Express has a big community with a lot of guides and tutorials written about it by developers that have been using it for quite some time.

You can easily add oAuth integration/social logins to your next web app without much hassle, using this authentication middleware for connect.

Very simple and fast.

If you have not already checked out the Express.js ecosystem of middleware, you should.

web2py documentation does not follow the common pattern of using Sphinx, MkDocs or ReadTheDocs which is goos for exeperienced developers. Although documentation in form of a book is very easy and good for beginners. Turning web2py the most easy and comprehensive framework to learn and also to teach.

Web2py apps are designed to be portable. With some minor restrictions web2py apps can run on any VPS on SQL databases and/or Mongo, as well as on Google App Engine with the Google Datastore. It is truly code ones and run everywhere. For example at Camio.com we use web2py internally to access a GAE datastore which contains more images than Instagram.

The web2py community is open and friendly and it gives concrete support to newbies and old timers. It's not difficult to get answers from the BDFL Massimo Di Pierro himself.

One really positive aspect of web2py application is their maintainability over the years. Old code works even if the framework is updated to the latest version. Not only that, if code is written well it is very short and a new team can pick it up over in little time.

While web2py has its own web based IDE which is convenient, it works with WinIDE, PyCharm, and Eclipse. The first two explicitly support web2py. The latter requires some configuration.

web2py is very easy to learn for beginners, yet it has a great deal of power and flexibility as application needs become more complex. It includes an impressively comprehensive set of features, making development very productive without the need to integrate a lot of third-party libraries.

The framework is really fast in production after some optimization and fine tuning which can minimize the memory footprint in order to make it run on a really small VPS or slice.

Allows users to easily extend functionality by using external libraries.

Models and controllers live in the context of the HTTP request. So the developer does not have to import the API to access this context at every request.

In other words, the models, controllers and templates in web2py use a domain specific language which uses pure web2py syntax and allows to import any module but exposes a few additional objects.

web2py includes an "admin" app that serves as a web-based IDE for web2py applications. It includes many features, such as application creation, compiling, and packaging; an error ticketing system; a code editor; a debugger; a controller doctest runner; Git and Mercurial integration; and one-click deployment to PythonAnywhere, Google App Engine, and OpenShift.

It is not intended as a full desktop IDE replacement, but it includes some helpful web2py specific functionality and can be convenient for basic editing and debugging tasks and quick prototyping, even for those who primarily work with a more full-featured desktop IDE or editor.
