Building SPA using MVC 5 and Angular is designed to build the application right from the grass root level. This Book is actually targeted to those people who are comfortable with ASP.NET MVC and Angular as this needs basic knowledge of both the technology. Throughout this book my focus will be on teaching you making a full blown application rather than explaining basics. For basics you can check my other book Hands on With ASP.NET MVC. This book talks basics in great details with live demo in Azure. You can refer this book at this URL I would recommend you to download the app from github URL shown below to help you while building

Glimpse of Movie Review App

Hi my name is Rahul Sahay and I am going to introduce this whole new story of building Single Page Application right from the scratch. Here, in this context I am going to talk about bunch of different client/server side technologies and demonstrate how these small pieces marry together and creates a robust End to End application. So, without wasting time let’s get started.

What is SPA:-
Single Page App is all about user experience. People will love your app if you give them nice user experience which not only fits nicely in your laptop or desktop rather it goes nicely with multitude of devices like tabs, phones etc without breaking any single functionality. As shown in the below diagram, these are basic requirements for building any SPA.


  • Reliability: – People know that it’s reliable and it’s going to work. This kind of reliability only comes with positive experience.
  • Responsiveness: – Responsiveness means it’s going to work quickly for them. Quick is the key thing which any user expect to have in the app which he is using.
  • Reach: – Reach is often substituted with mobility. Mobility is again one of the key ingredient which every user is looking for. They always want to have the data handy with irrespective of what device they are on.
  • Available: – This thing is really important when it comes to the point at working offline. So, delivering a good user experience is must while building SPA.

So, in a nutshell a Single Page App is web application which fits in a single page providing a fluid UX by loading all the necessary data in a single load.


Now, apart from this there are many other attributes linked to SPA. They are:-

  • Maintain History: – When you flip between pages, it maintains your history in the same order how you visited them. Actually, it’s not going on different pages rather its loading different information’s on the same page. But, it looks to user that it’s presenting different pages to them.


  • Persisting Information: – Persisting information is also very important aspect of the SPA. It doesn’t mean that you need to save each and every thing at cache but you can store important things in the cache to improve the performance.


  • Mostly loaded on Page Load: – Mostly loaded on the page load means majority of information user required to use gets loaded initially itself to avoid roundtrip back to the server.


  • Dependent Elements: – As and when user requires to access different features of the application, app will go and download for the user.


Technologies used to build SPA:-

Movie Review app is built using tons of different client side and server side technologies. Some of these I have listed below:-

Client Side Technologies:-

  • HTML 5 & CSS
  • Modernizer & LESS
  • Media Queries
  • Responsive Design
  • Angular JS
  • Toastr JS
  • JQuery
  • QUnit JS
  • JQuery.MockJSON
  • Change Tracking
  • And many out of the box things

Server Side Technologies:-

  • SQL Server
  • Entity Framework – Code First Approach
  • Repository Pattern
  • Unit of Work Pattern
  • Web API
  • NuGet
  • Ninject IOC
  • POCO Models

Glimpse of Movie Review App:-

I think it would be good idea you to show you finished app before directly jump in creating the same. Here is the URL where I have hosted my app. Now, when you click on this, you will land on the below shown page.



Above shown screen shot is the home page of the app. Now, when you click on the Movies link, it will take you to the below shown page.


Once, page gets loaded, little toast message at the bottom right of the screen pops up saying Movies Fetched Successfully. Now, from this screen you can do all the CRUD Operation. Here the very 1st link is Add Movie, which will give user flexibility to go ahead and add any new movie as shown below.


Now, let’s suppose if we try to post the Form as it is blank, then it won’t allow, because above fields are required as marked by its CSS color and star mark as well. Now, once I enter any information, different validation will get triggered


Even at this moment I cannot submit the form as the form is invalid. Once, I modify and enter valid details, then form error messages and its error color (Red) will disappear.


Now, at this instant I can go ahead and submit the movie. Once I click submit button; one toast message will appear saying Data Saved Successfully and will get redirected back to movies link.



Next is the Edit link corresponding to the movie. When you click on this, it will present the below screen for editing the same.


Here, also each and every validation will be there, what we have seen during creation. However, you can go ahead and edit anything over here, let’s say I change the year to 2002 and update.


Once I update the movie it will save the same in database and then get redirected to Movies link as shown below.


However, let me change the same back to the original one as it’s not correct. Similarly, you can go ahead and delete the movie from the Edit link as well. Next to Edit link, there is link for Reviews as well. From this link you can go ahead and add new review as shown below.


Here, when I click on Add New Review, it will take me to the below form.


Above form has also got different set of validations as shown below.


Once done all the corrections, it will be like this


After successful, submission, it will redirect back to the movies link.


After adding Review, position of newly added movie moves up in the list as behind the scene order by clause is working on total no of reviews. Now, when I click on the Reviews link again, it will show me the review which I have added.


Here, corresponding to the Review, new Edit link also got enabled for editing or deleting the Review. This also works same what I explained above for Movie. About App link lists all the details of the application like what technologies used what tools you need, where to download the code etc….




I have also used QUnit Library to test my Web APIs. Below is the glimpse for the same.


When you click on any individual test, it will present you the detailed results as shown below in the screen shot.


And if there is anything wrong with any end points, let’s suppose that doesn’t exist; easiest way to break the test, then it will be like


You can also verify these APIs like shown below


Similarly different endpoints can be tested. Apart from Web API tests. I have also used Jasmine to test my Angular code. You will also learn how to test client side JavaScript code with Visual Studio. Here, I have used Chutzpah to integrate JavaScript Tests with Visual Studio. Below is the glimpse for the same.


Now, when I check code coverage results for my tests, Chutzpah will open a new window in browser with the code coverage results for the client side as shown below in the screen shot.


The ones which are highlighted in red are the ones which are not covered 100%, so when I click on any of this link, it will open the code in browser and show what is covered and what is not


Glimpse of Movie Review Solution:-

Let me go ahead and show you the solution structure of finished app. Below in the screen shot, I have 5 different projects. Each is having its on dependency and responsibility.


Here, the highlighted one is the web project which is dependent on other infrastructure projects Data, Contracts and Model. Data project is the place where in you maintain initial seed data, Entity Framework DBContext and many more things involve direct interfacing down the layer with database. Data Contract is the place where in you manage your repositories and apply Unit of Work Pattern on repositories like movies and moviereviews. Model is the place where you will be having your POCOs (Plain Old CLR Objects). This is the place where in you are maintaining all properties attributed to the tables. Below is the glimpse of all projects in its expanded form.

In this section, we have seen the bits and bytes of the Single Page Application which we are going to make using tons of client/server side framework. We have also seen the glimpse of app and solution. In the next section, we’ll begin the learning by creating the application right from the scratch. I would recommend you to download the app from github URL shown below to help you while building .

I hope you have enjoyed the glimpse. More more info you can have the same from the below mentioned link.

Happy Coding

Glimpse of Single Page App using ASP.NET MVC 5 and Angular

Hi Friends,

It’s been long since i blogged any thing but it’s ok as i was working on one of the assignments which i shared few days back where in i’ll be wiring up bunch of technologies to make a robust SPA. Here, is the glimpse of the app what i have been working on.

Looks like my git shell has been corrupted, hence not able to push images in git. not a problem, will fix the same some time later, but for now let me upload images here itself.

However, below is the solution structure for the same. However, this is still incomplete as i have not yet added the testing project. But that’s ok, will be adding shortly and publishing the same shortly…Now, below is the glimpse of variety of technologies used so far to make this app…

Technologies Used

Client Side Technologies

Server Side Technologies

so, the one showed below is the web project rather web api project talking to and fro with my other projects listed here. Here, the crucial things are api controllers and my client side scripts “Angular” here for delivering the same back to UI. Other projects are equally important where in one is having models project which is keeping my plain classes then contracts project which is the medium for Unit of Work Pattern and Repository Pattern. Then the last one is Data project where Entity Framework is playing it’s role. Here, I have also used design principles like Single Repository principle to keep the things simple and clean and Factory Pattern to create the required instance in case if that is not created earlier by the app. Like this there are variety of out of the box things i used in this app which you will experience once you start building this app right from the blank state.












Below, is the glimpse of all api controller sets and the same in action as well.




Now, at the end my two driving factors of my app; my two Angular files.

Here, i also used qunit.js to test my api controller. Below is the glimpse of api test resources and their test results.




and below is the snippet used for the same.

I hope you liked the glimpse, stay tuned for complete step by step tutorial. Till then stay tuned and Happy Coding.


Things every good developer should know!

Hi Friends,

Today, i have started working on one of my app framework projects where in i’m brushing up all required skills to write a good application framework. Basically, application framework i would say one time investment and long term return means if you write good framework initially, then you can smartly focus on business requirements at the later part. So, basically any application framework involves below listed bullet points like

1) General Naming conventions
2) Data Access Design
3) DI Technique say Ninject, Structure Map …etc
4) Error Handling and Logging Events
5) Security Infrastructure
6) UI Design
7) Client/Server Side Validations
8) many more can be listed, but these are basics.

But, the point is for writing these, you need to have good implementation knowledge of below listed points.

  • SOLID Principles – These principles have helped me a ton. They aren’t just rules to be followed blindly, but I’ve found that  reasoning behind them and trying to make code clean, easy to understand, testable  in the long run.
  • Design Patterns – Certain types of problems always come in software development. For these scenarios, we have design patterns. Getting hold on design patterns is something that only comes with practice. You won’t be able to memorize and recognize even the core set of patterns immediately, but over time you will recognize the same easily.
  • Test Driven Development – Make it habit or in your DNA. It not only helps to test the code, it helps me design my code. That’s a big advantage that a lot of people overlook. It also gives me confidence that the class I’m creating does exactly what it is supposed to do, and nothing more. TDD also makes sure that if you are adding any new feature in your application that is not going to break the existing ones, if all tests ran expectedly.
  • Resharper  – Resharper is essential for doing C# development in my opinion. Out of the box, it will suggest lots of little things that can help improve your code. It helped me learn LINQ by offering to convert tedious long code into elegant LINQ expressions, and it finally convinced me that ‘var’ isn’t always evil.
  • Lambda expressions – These are essential when working with C# . They’re a bit hard to grasp at first, but they open up very interesting re-use possibilities, and lots of APIs leverage them heavily.
  • Generics – This is an older C# feature, but still this is one of the most important piece to learn.It opens up new avenues for creating clean, extensible, and reusable classes.
  • StructureMap  – One of the biggest change at the moment. This totally changed how one code. Now when I realize a class I’m working on is going to need some other service to fullfill its responsibilities, I simply create a new service interface and add it to my class’s constructor. This makes my development much easier.
  • LINQ – Make this habit as well. I am still learning LINQ. Most of the times for complex queries i make use of LINQPAD or refer msdn Linq samples.
  • Moq – Mocking frameworks allow you to configure stubs or fakes that you can substitute for dependencies while testing your classes.  Moq is one of my favorites for its fluent, lambda-based syntax. off-course this piece also i always try to make use of as much as possible.

So, these are the few things in my opinion are must have things for any mature developer.
