During the last past days I have been to a conference in Germany and brought back several interesting things I want to share with you this time. (Here I have to say that my hotel did not have a spa. So everybody who wanted to get the latest hotel and spa tips is wrong here…so in case stop reading)
Well for me as a software developer it gets interesting every time I hear another company talking about their way of doing work, their kind of projects and their behavior in the market. It’s always refreshing to see how they behave. And, indeed, personally, if the topic “ASP.NET&”, “Internet&” with all its Buzzwords is connected you can be sure to have my attention.
This time I laid my focus on everything which was connected to the web and in eight hours of workshop and a lot of tracks the other day I learned a lot!
Let me get historical for a moment: .Net in its first version was released in 2002. This is 12 years ago! 12 years are more than a lifetime in computer-science. So you feel that there is something moving. Something growing. Internet-Applications are getting bigger and bigger and: It’s getting a lot more mobile focus. Having the same application on smartphone, tablet and your desktop-PC (Do you still have one? 😉 ) is something like essential to everyone. It also solves a lot of business-issues as I heard on the conference. “Oh if we would have known that before. It would have saved us a lot of trouble!&”
ASP.NET gives us great application-possibilities for this to achieve. ASP.NET MVC gives us a very established Framework (MVC) which does a great separation of your view, your logic and dealing with and between them. But it’s a server-sided technology. You are feeling it: There is a server I have to ask every time. I hated to ask my parents for almost everything I did when I was young, why should I love to ask a Server everything I do? And, which is the bigger point, why am I feeling it while working with my application?
Wouldn’t it be nice to have an application browser-based, which looks the same on every device I have, which keeps my data synchronized no matter which device I take to change the information? I can start it on my smartphone, have it on the desktop and love the information AND the look and feel. Because I am used to it.
The following screenshots shows an example of a view iterating over persons, which are called from a WebApi over services (see the following screenshots).
The controller gets the “scope” injected, which is an angular.js-word for representing the view model. Here the persons are called from the service and set in the corresponding property.
Here the services for the communication to the WebAPi are shown. I only divided the service which gets injected to the controller from the one who really gets the data. Theoretically this could be one single service.
Your corresponding WebApi could look like:
The last piece which fits everything together to get a real feeling of client-based-architecture is the routing, which you can navigate to your application with without having the feeling there is a server behind.
With this angular.js-concept and WebAPI in the back you can get your information online, take it to your client and work with it. Navigation is client-based. Every behavior but the source of information is based on the client.
