An
important component of the decision to use a framework should be the amount of ceremony and ritual involved. You must carefully weigh what it takes to ramp up on the technology and how common tasks are performed. It does no good to adopt a library that forces you to solve a problem with more effort than it would take using your basic tools. One of my favorite examples to showcase technology is a simple feed reader. Several years ago I recorded a video to demonstrate how to build a Silverlight MVVM Feed Reader from Scratch in 30 Minutes. It opened a lot of eyes for people who thought MVVM was overcomplicated.
HTML5 and JavaScript have matured significantly and it turns out it is even easier to build a similar application from scratch using tools like Angular (I even throw in some Twitter Bootstrap styling so it looks halfway decent). One of the things I really like about Angular is that it is really doesn’t involve a lot of ritual or ceremony. In fact, in this video I probably take too much time doing things like setting up a title and writing constructor functions instead of just in-lining the code for my controllers and services.
Nevertheless, I manage to make a functioning feed reader entirely in the browser from scratch in less than 10 minutes. In the video below you’ll see how to bootstrap Angular using the Content Delivery Network (CDN), set up your initial app, add a controller, then add a service and wire everything together. I even show you how the built-in forms controller automatically handles disabling the submit button for me when I specify the input type as a URL and note that it is required. Enjoy this video as it illustrates how Angular can save you time building your web-based apps:
