From Zero To Vue With Asp Net Core Razor Pages In Ten Minutes

While MVC is the legacy tool to put together the front-end of a .NET app, Razor Page offers greater functionality and is a lot similar to MVC. It has all the syntax and functionality of MVC and has the model and controller code included in the Razor Page itself. It uses an MVVM (Model-View-ViewMode) framework to facilitate a more straightforward development experience and enables two-way data binding. If you’re coming from a different programming language, or a Winforms/Webforms background, modern day ASP.NET can be pretty confusing. You want to learn how to build a simple page, maybe show some data but instead you find yourself drowning in a sea of terminology. Single page application – I feel choosing this option is not going to be wrong in any scenario.

Interestingly, although WASM is an alternative to JavaScript, it can be considered as complementary and not at all contradictory to the same. In other words, Web Applications designed with WASM can work alongside those developed with JavaScript. The Viper Scale Racing AFX Mega-G+ Rear Axle Assembly is a great performance upgrade for any AFX Mega-G+ and the original Tomy AFX Mega-G HO slot car. The Viper Scale Racing AFX SG+ offers a high performance, light weight, low rolling resistance front end for a better handling slot car. I’m not sure if Polychromatic has anything very useful for me as only Razer device I have is a mouse and most of the settings were applied correctly automatically.

What Is Asp Net Razor Pages?

Its component model is simple enough that it maintains a short learning curve, yet is robust enough to be extremely productive. Even though Razor Components is new, its ability to use existing .NET libraries, tooling and optionally JavaScript’s ecosystem as well makes it a strong candidate for frontend web development. The component model is easy to learn but provides a robust base to build complex UIs.

  • But the result is being able to run C# code on the client-side.
  • The first source of the configuration is theappsettings.jsonfile in the root of the project.
  • If you’re coming from a different programming language, or a Winforms/Webforms background, modern day ASP.NET can be pretty confusing.
  • The login component will call the service class and the service class will call the back end.

It is the most flexible and most popular of all JS frameworks, but its steep learning curve can challenge new dotnet developers who may not be familiar with it. There are so many different ways to create a web application today, it’s staggering. We have lots of different languages, different clouds, different server-side runtimes, and different deployment tools.

But the other choices need a server side, and that’s exactly where ASP.NET Web API comes in. We also have other options like ASP.NET Core Minimal APIs and Azure Functions, but we’ll talk about all that in the next part of this series. The issue came up when needing to reuse my list form on multiple pages. I needed the exact same form and exact same list in three different forms.

During the last couple of years I’ve been doing lots of web development with technologies like JavaScript and PHP and Zend Framework, with a strong focus on the front end. Before that, however, the vast majority of the work I did as a web developer was with the .NET Framework. If you’re interested in learning more about the differences, check out this post comparing MVC and Razor Pages. A page model, which handles the accessing and processing of information. On the upside, you’ve got the simplest technology of the bunch. One cool detail is that the code for Blazor Client and Blazor Server are pretty similar. Up to a certain point, after all, Blazor Server runs on the full .NET runtime, whereas Blazor WebAssembly runs in a minimized WASM Mono runtime.

Web Api

This setup is for the Auto World X-Traction, AFX Magna Traction and AFX G Plus HO chassis. This is a great upgrade over stock and will increase on track performance. Let’s create a config.ts file inside our config folder and call the class AppConfig. This is where we can set all the values we will use in different places in our code; for instance, the URL of the API. Note that the class implements a get property which receives, as a parameter, a key/value structure and a simple method to get access to the same value. This way, it will be easy to get the values just calling this.config.setting[‘PathAPI’] from the classes that inherit from it. Outside the app folder we will keep the folders created by default, like assets and environments, and also the root files.

Thus theGlobal.asaxfile, which was used for this purpose before, has disappeared. As mentioned earlier, the .NET Core app host can only start console applications, so web projects also need an instance ofProgram.cs. Web Application (Model‐View‐Controller) creates the full‐blown project with everything you might need in a web application. Now that all the pieces are ready, the application can be executed by simply typing the commanddotnet run.

Blazor Evolved From Razor As An Ideal Alternative To Single Page Application Frameworks:

In another file we can now set the CountBy value on the component element. With the client – server relationship understood, now we can focus on the UI portion of the framework. Examples might be simplified to improve reading and learning. Tutorials, references, and examples are constantly reviewed to avoid errors, but we cannot warrant full correctness of all content. While using W3Schools, you agree to have read and accepted our terms of use,cookie and privacy policy. Making statements based on opinion; back them up with references or personal experience. So, to answer your question, Razor is a front-end technology that executes on the server-side runtime.

  • For this initial overview, you will select the Web Application (Model‐View‐Controller) template and proceed through all the pieces of the puzzle.
  • OWIN defines the interface that components, be they full‐fledged frameworks or just small filters, have to implement in order to be instantiated and called by the hosting process.
  • Blazor offers all the features that a Single Page Application has.
  • They also have some of the server‐side logic of HTML helpers, so, for example, they can read the value of the view model and conditionally add CSS classes.

This means that Razor Components apps cannot work in offline mode. If offline mode is a must for your application, then the WebAssembly equivalent Blazor application may be a better choice. With that said, Blazor has yet to receive an official release date or promise of support from Microsoft. Since Razor Components runs server side as a .NET Standard app, logic is written using .NET technologies. This is possible due to the Blazor framework which employs the RenderTree, a DOM abstraction similar to virtual DOMs used in popular JavaScript frameworks like Angular and React. Let’s look at UI side of the framework to understand how components are written. Razor Components has a unique architecture that allows a .NET application to run server-side while the user interface runs out of process in a remote browser.

A basic Blazor application could carry with it anywhere from 2 to 3 MB. While this may not be viewed as a large size by ordinary end users, it is considered a heavy load in the world of web applications. Interestingly, simple caching substantially reduces the data during subsequent reloads. This flexibility and versatility allow Blazor apps to be nested and re-used with minor tweaking. The result of how to become a .net razor developer a web application developed with Razor and Blazor is apps that perform with high reliability, speed, and efficiency. Not mention, the framework allows the development of rich user interface that’s rendered as HTML and CSS. Despite the rising usage of Razor, .Net developers still had no powerful alternative that directly countered JavaScript framework like Angular, React and Vue on the frontend.

ASP.NET provides a number of ways to build web apps/services. We focused on one called Razor Pages, which uses a page-focused (View Page + Page Model) pattern. Razor Pages can also be used to make things other than web pages, like APIs and microservices. (Remember when Microsoft said ASP.NET is good for web apps AND services?) In those cases we wouldn’t need a view page, we’d just use page models. I hope this post helped in some way, possibly making sense of all the different pathways you can take when building a web app. Check out the next part where we’ll see all the great server-side options .NET has to offer.

With its efficient and compact binary format, WebAssembly can promisingly run with near-native performance and efficiency. Now if you run the app and browse to /counter, you should see a blank page, ready to go. We’ll add a counter component to this page and make use of the backend portion of the razor page to keep track of state. This will add a blank razor page inside the pages folder in the app called Counter.

With this option your ASP.NET Core API is primarily interested in returning data when asked for it, or handling data it’s given (usually to persist it somewhere e.g. SQL database). The SPA makes calls to your API to retrieve data which it then merges with views/templates.

The Authenticate method just has user validation hard-coded for the moment, but we will need to call the database to validate it in the end. To fix this issue is very simple, we just need to create the service provider file configuration.

Razor Helpers

This code changes the default inheritance of the Razor View Page Model so it inherits from the BookStorePage class . The BookStorePage class which comes with the startup template, provides some shared properties/methods used by all pages. Instead of classic MVC, we will use the new Razor Pages UI approach which is recommended by Microsoft. You can try to execute the /api/app/book API to get a list of books. This DTO class is used to get book information from the user interface while creating or updating a book. DTO classes are used to transfer data between the presentation layer and the application layer.

We’ve done SPAs using Vue for the front-end, and ASP.Net Core 2+ for the backend. Sometimes though, we have just a page or two that needs to be more interactive, that needs to have that “SPA feel”. Thankfully for sites like that, you can integrate Vue with Razor pages in about 10 minutes to get the best of both worlds.
