OutSystems

OutSystems excels with building web interfaces fast and lends itself to custom integrations written in .Net. Most anything can be brought in given this ability to be extended. One of the drawbacks to the speed of development is that most quality control teams become quickly overwhelmed and may be unable to keep up.

React

React is great for people who are trying to build complex single page web applications. It is intuitive for developers, encourages modularity through components, and provides a web app this will scale. React may not be suited as well for simple websites or static content. However, this is changing with frameworks like Gatsby which allow you to build static HTML websites using React.

Pros

OutSystems

  • Deployment management – OutSystems has a built in robust, multi-environment deployment system that helps ensures the clean and error free deployment of applications through the development, testing and production product lifecycle
  • Rapid application development – Through the low code, graphical development environment you can develop applications far quicker than with more traditional development environments
  • Cross platform mobile development – OutSystems handle the development and building of mobile application for both iOS and Android in a simple streamlined way that removes 90% of the problems normally associated with multi platform development

React

  • React is designed around the notion of generated html as opposed to templated html. This provides more flexibility in building elements on a page, and allows developers to create html that is programmatically configured based on runtime considerations.
  • React uses JSX, which is HTML templating integrated into javascript code. This simplifies the generation of complex structures, especially those that vary based on runtime and interactive data.
  • React is more efficient because it generates a virtual DOM rather than directly building in in the actual DOM. By building 'offline' in this manner, the DOM generation is faster. After building, it can be installed in one operation.
  • React only builds those portions of the display that have changed, making display updates more efficient.

Cons

OutSystems

  • The platform controls all the parts. While great for development and overall maintenance, it could lead to discussions with your DBA (who has to trust the platform). As a developer I love the platform, as a DBA I would like more control.
  • By making software development model driven using flows, you are forced to rethink the way of programming. It makes it easier, but sometimes the way of working leads to code which could be optimized (standard problem in model based software development).
  • Most of the code is generated, so the technical knowledge of the inner working of coding are not Essentials. This could lead to degration of this knowlegde. As part of this, most technologies will only be used when OutSystems supports it. They do a good job on implementing these things. But things like Node.js would be nice.

React

  • React could get very frustrating unless you start thinking in React. React enforces a top down hierarchy of data flow and offers no way for the data to communicate backwards. This is a big shift in mindset coming from Angular 1.x. This constraint is really a big factor that determines how to organize your code and how you might want to write your own Components.
  • Because of the self imposed top down hierarchy, you end up having a heavy parents with dumb children. Because parents would need to the bulk of the work, they usually manage the state, while passing callbacks to the child components. If not properly designed, this could lead to the callback hell, where you could have callbacks passing through like multiple children.
  • As with any library, you will have to iterate through multiple designs to come up with a ways to avoid "heavy parent components" in React. One obvious solution is using some open source tools like Redux, but we opted for a variation of it to suit our needs.

We are very happy with OutSystems and our developers deliver good work. OutSystems lets us build new software on a regulare (2 weekly) basis, which is highly flexible and adjustable. Even without very much experience, our developers manage to build usefull software, which is working a lot better than our previous (legacy) software.

I am really happy using OutSystems in my work. It gives me the opportunity to create good working software without having had very much IT-experience before. It also made me more interested in the background of IT and learning different languages.

React is just a bit of a different animal. I was avoiding it for the longest time. I thought for sure I would land on Vue or something else with a more approachable and familiar appearance. But after taking an online course in React, I started realize what people were raving about (and complaining about) and decided to implement it at our office for one of our products.

In becoming bigger, the support encountered several growing pains, but we've seen amelioration (also by involving a customer engagement manager, more direct lines with OutSystems, and better contact with partner Noesis). Sometimes growing goes fast and the organization needs to adapt to the new world. New markets are conquered, but others still need to grow.

Alternatives Considered

OutSystems

I tried to use WordPress with some success. Also looked at Joomla. But when I saw OutSystems I knew I had been wasting my time there. It takes you longer to get going with OutSystems - but even I as a novice realized immediately that Outsystems is simply in another league. Outsystems is powerful. (Can you compare WordPress and Joomla to Outsystems - I don't think so).

React

I have also used Vue, Angular, and Ember for various projects. Out of the three, I am most intrigued by Vue. It takes a more beginner-friendly approach than React and changes some of the abstractions it uses to be more transparent to the user. It also comes with a lot more "built-in" than React. Angular is similar, but I've found it over-engineered and hard to work with. I have the least experience with Ember out of all of these, but it seems like another reasonable alternative with very strong conventions in place and an excellent CLI.

Return on Investment

OutSystems

  • The ease of use of the OutSystems development process has been the biggest ROI for us. We have developed our Framework product and maintained/enhanced it with only 4 workers.
  • OutSystems has enhanced their product very significantly over the last 4 years. They have gone from a simple to use tool to a very simple to use sophisticated tool that covers the standard mainframe-based computing apps and the apps used on handheld mobile devices all using the same basic set of development tools.

React

  • React sped up the time to implement new features, providing much better code-reuse across the team
  • React's excellent performance made it so new components ran faster in the browser
  • Since React is so popular, it's been easy to recruit new developers to the team who already have a familiarity with the library
