c# - MVC 5 Single Page Application Template - Stack Overflow

A Single Page Application SPA is a different way of building HTML 5 applications from traditional Web page development. Instead of spreading the functionality of your Web applications across a collection of separate Web pages with hyperlinks between them, you instead define a single root page that the user lands on and never leaves as long as they are working with your application.

You define client-side logic that switches out the data and chunks of content within that page to allow the user to navigate from logical screen to logical screen without ever leaving the page.

This means that the user never sees a full page refresh while using your application. They see portions of the screen change based on single page application in asp.net mvc 5 interaction, and those changes can be done in a more fluid way with transitions to enhance the user experience.

You can also support using the application while offline by storing data client-side, based on some of the newer APIs of HTML 5. Taking this approach makes an SPA feel very much like a desktop application to the end user. A good example is the Gmail Web client. To do all that, you need not only the mechanisms that do the navigation between logical chunks of content within your main page, but you also need some good client-side support for making service calls, getting data to the client side and caching it there, allowing the page to present it, change it, validate those changes, and submit changes back to the server side.

This article focuses on that data support, which is what the Upshot library that is part of the ASP. NET SPA stack provides. NET SPA stack. You need to know few things about the architecture of SPAs and the capabilities of Upshot before you can dig into some code, single page application in asp.net mvc 5. The general architecture of an SPA in Figure 1 shows where Upshot fits in the client-side architecture, and the data services in that diagram are supplied by the DataController services or by WCF RIA Services DomainServices.

If you build a traditional ASP. NET Web application, you rely on post-backs and server code to figure out what to do when the user navigates and interacts with your application.

You handle all the single page application in asp.net mvc 5 manipulation and interaction logic on the server side, single page application in asp.net mvc 5. When you build an SPA, you put all of that on the client side in JavaScript that runs in the browser. NET programmers, that may sound like crazy talk. The idea of writing piles of JavaScript code to handle all the stuff that ASP, single page application in asp.net mvc 5.

NET makes easy for you, plus all the interaction and data manipulation logic that you are used to writing in C or Visual Basic, probably sounds like it is a great way to extend your project timeline and get your project cancelled. But the HTML world has evolved quite a bit from the traditional model of Web development.

You can build HTML 5 applications with the support of a number of client-side JavaScript libraries that provide functionality, making it much easier to write portions of the functionality on the client side to enable a much richer and responsive user experience.

These same approaches are also enablers for structuring your application as an SPA. You also need to change the way you manage data when building SPAs. In a traditional ASP. NET Web application, you do your data retrieval and modification in the page-handling code on the server, then render out a new page containing the data or the controls to enter changes to the data. When you build a traditional application like this and you are constantly navigating from page to page, the browser sets a new execution context on the client side with each page switch.

As a result, you have no opportunity to retain state in memory in order to have an ongoing interaction with the same set of data across multiple user navigation steps e. In an SPA, you can retain references to data in JavaScript on the client side because the user never leaves the main page while running your application.

With HTML 5, you also have the opportunity to persist that data on the client side across multiple user sessions and even run the application and access the data while offline. You get your data in an SPA via service calls made from the client-side JavaScript. The initial root page rendering from the server single page application in asp.net mvc 5 the root structure of the page, as well as possibly an initial data set.

But the first thing the application usually does is make an asynchronous AJAX service call from a script to get the latest data to support the current child views presented by the root page. Then, as the user navigates or interacts with the page e. switching from inbox view to contacts view in a mail clientsubsequent service calls are made to refresh the client-side cache of the appropriate data, and the UI updates without a full page refresh.

html for working with data resources on the server side. Upshot allows you to pull data to the client side, cache it, lets your client script make changes to the data, validates those changes, and makes the calls to pass the modified data back to the server side. NET Single Page Application is the official name of the capabilities as of the beta release of ASP.

NET MVC 4. The stack includes both the client-side support the Upshot JavaScript library and some server-side support to define the services that Upshot can consume. Upshot is not limited to building SPAs with HTML 5. Even a page-navigation-oriented Web application could use it to retrieve and update data within different pages in the application.

In fact, the demo code single page application in asp.net mvc 5 this article does not involve any complicated navigation within a single page; it covers the basic usage patterns of Upshot and the services it consumes, which are more single page application in asp.net mvc 5 on data manipulation on the client side than how the application is really structured at a UI level.

Upshot is part of the ASP. NET SPA stack because you need the kind of data support it provides for SPAs, single page application in asp.net mvc 5. The services that Upshot can consume include WCF RIA Services DomainService classes as well as services defined on the new ASP, single page application in asp.net mvc 5.

NET Web API stack. WCF RIA Services was originally designed primarily for Silverlight clients. Upshot extends the reach of RIA Services to include HTML 5 clients as well. So the SPA stack includes three things: the Upshot library for the client side, the server-side DataController and metadata support classes, and tooling project and item templates to write the code faster.

The SPA stack includes three things: the Upshot library for the client side, the server-side DataController and metadata support classes, and tooling. NET SPAs. You need some services for the client side to consume before you can see how to use Upshot.

Single page application in asp.net mvc 5 first thing you need is some data to work with, because the core capabilities of Upshot and DataController services is on implementing a Unit of Work pattern around data retrieval and update CRUD.

A DataController is a class built on top of the ASP. NET Web API for exposing HTTP Web Services. They support handling URI-based routing and parameters, HTTP verb handling GET, PUT, POST, DELETEcontent negotiation determining the format of the message based on Content-Type, Accept HTTP headers, and media typesand automatic deserialization into strongly typed model objects.

The DataController class can be directly derived from if you need full control of the data access approach you are going to use, or you can use the DbDataController or LinqToEntitiesDataController derived classes as the base class for the controller you define. DbDataController works with Code-First Entity Framework models and LinqToEntitiesDataController works with EDMX data model classes.

These controller classes use a common infrastructure with MVC page-oriented controllers, but are used to define something that will be exposed to the client side as an HTTP Web API - a non-SOAP formatted Web service. Create a new project using the ASP.

NET MVC 4 Web Application project template. In the dialog that is presented containing multiple kinds of MVC 4 projects, select an Empty project. I am not using any SPA project templates for this article because their status is in flux at the time of writing. The Empty project does not have the assemblies and scripts you need to build an SPA, so you need to get a NuGet package. DataController services are easiest to define if you use Entity Framework as your underlying model because there are derived types that encapsulate some of the code required when working with an Entity Framework model.

Upshot includes support for working with Database-First or Model-First EDMX Entity Framework models, or Code-First DbContext Entity Framework models. I use Code-First in the sample code. The SPA solution in the sample code uses the Northwind database as the data source. Notice the [Key] attribute on the CustomerID property. The DataController class recognizes the DataAnnotations namespace for that attribute, and others are defined and can use them to help manage the round-trip transfer of the data as well as to support client-side validation of data changes.

To do the data access for customers, define a DbContext derived class that exposes a Customers collection as a DbSet. config file named NorthwindDbContext that points to the Northwind database. The sample code includes a SQL script file to create that database so you can run the sample. Real-world data models can get a lot more complicated than the demo code model. DataControllers and Upshot can handle one-to-many, one-to-one, and many-to-many relationships between objects.

A simple controller class for exposing the Customers collection to the client looks like this:. You can see that the base class exposes the wrapped DbContext class passed as a generic type parameter so that you can get to it through the DbContext property on the base class.

The base class takes care of the instancing of that class and the basic query patterns. Data retrieval calls HTTP GETs will be routed to the query method using an ASP. NET Single page application in asp.net mvc 5 Service action parameter. When an update comes from the client, it comes in as a POST request, and gets routed to a method on the base class called Submit that takes in a ChangeSet representing the Unit of Work from the client.

The ChangeSet can contain multiple inserts, updates, and deletes of items in the underlying resource collection. However, if you are using the DbDataController class, you can simply call the base class methods and it will take care of the Entity Framework calls required to persist the changes.

You will need to provide specific routing information for the DataController service because the default routes for an MVC project do not use the same URI conventions as Upshot does for routing the calls to the service.

Area registrations are automatically discovered in an MVC application based on a call made in the Global. asax class. The following code shows the necessary area registration for the CustomersDataController class.

NET to render the basic structure of the page. There is no MVC magic required for rendering a page that uses Upshot, just good old HTML and JavaScript. Upshot leverages JQuery and you will want to in your client-side JavaScript as well, so that is the first dependency. Knockout is a separate JavaScript library that allows you to data bind HTML elements to JavaScript objects and properties in a fashion very similar to XAML data binding, and also supports the Model-View-ViewModel MVVM pattern in client JavaScript.

It needs to be there because Upshot single page application in asp.net mvc 5 the support of a library that has an implementation of an observable object. An observable is a JavaScript object that can raise change notifications to subscribed objects when the object properties change, much like the INotifyPropertyChanged interface pattern in.

NET code. Knockout provides this capability, but you could substitute a different JavaScript library that provides similar capabilities. In the current release, single page application in asp.net mvc 5, Knockout is the only supported library that works with Upshot.

Next, open a JQuery ready handler and start filling in the body of that function the ellipses with the Upshot code.
