C++ Web Toolkit Wt (witty)

During the last days I made a simple web application, which serves you chess puzzles to solve. You can see it here bestmove.abrok.eu.
Before starting this little project I decidet to use Wt as a framework to learn something new. Also it seemed to be very easy to use and had similarities to Qt which I am already familiar with.
I want to share my impressions after my first little project with it. I will start with my negativ impressions:

  • The ownership of objects does not feel clear at the beginning. Although there are rules for ownership, there are special cases which may not be intuitive at the beginning.
  • Even for my simple application there were some Wt related bugs that cost me some time.
  • Because Wt is a serverside framework, your UI could feel a bit slow. Wt solves this for some standard usecases. For example a menu widget can preload all its child widgets and switch its content client side. If you want more special things, e.g. change the border color of a widget when it is clicked, you either accept the latency or you have to write javascript code for this. The good thing is Wt offers good ways to integrate javascript.
  • You can choose the layout between two predefined styles and a “bootstrap” theme (in version 1, 2 and 3). In my opinion there could be more predefined themes, although I did not realy miss them.

Of course there are also many good things to mention:

  • Wt comes with many basic examples you can learn from.
  • It is very active developed. All bugs I reported got fixed within one week.
  • All communication between client and server is handled by Wt. This makes web development feel like developing for a desktop.
  • You dont have to care what browser the client is using. Wt handles this.

If I would use Wt again for my next project depends on the complexity of the UI and the communication with the backend. If the UI is extremly complex I would probably choose another framework like GWT, because to make the UI fast you need to have client side code. If the UI is not to complex, and the focus lies on the backend, I would definitely use Wt again.

One thought on “C++ Web Toolkit Wt (witty)

  1. Hi,

    I am just thinking to dive into Wt. I love web developement. I have good experience with C++. I have done some web development in PHP but having come to know web development can be done in C++, I felt both over joyed and terrified. I read a few more posts which warn against using C++ for web development. Also I have heard it can take you weeks to do a tiny task in witty sometimes which you can do in a flash in other web frameworks / languages. I hope you understand the dilemma I am in. Please HELP!
