Category: Razor pages vs react

By Daniel Roth and Luke Latham. Blazor apps are based on components. A component in Blazor is an element of UI, such as a page, dialog, or data entry form. The component class is usually written in the form of a Razor markup page with a. Components in Blazor are formally referred to as Razor components. The following Razor markup demonstrates a component Dialog. The dialog's body content ChildContent and title Title are provided by the component that uses this component in its UI.

OnYes is a C method triggered by the button's onclick event. HTML elements specify components, and a tag's attributes pass values to a component's properties.

In the following example, the Index component uses the Dialog component. When this component is used in the app, IntelliSense in Visual Studio and Visual Studio Code speeds development with syntax and parameter completion. Components render into an in-memory representation of the browser's Document Object Model DOM called a render treewhich is used to update the UI in a flexible and efficient way.

Blazor Server is supported in ASP. NET Core 3. Blazor WebAssembly is a single-page app framework for building interactive client-side web apps with. Blazor WebAssembly uses open web standards without plugins or code transpilation and works in all modern web browsers, including mobile browsers. NET code inside web browsers is made possible by WebAssembly abbreviated wasm. WebAssembly is a compact bytecode format optimized for fast download and maximum execution speed.

WebAssembly is an open web standard and supported in web browsers without plugins. WebAssembly code can access the full functionality of the browser via JavaScript, called JavaScript interoperability or JavaScript interop. NET code executed via WebAssembly in the browser runs in the browser's JavaScript sandbox with the protections that the sandbox provides against malicious actions on the client machine.

The size of the published app, its payload sizeis a critical performance factor for an app's useability. A large app takes a relatively long time to download to a browser, which diminishes the user experience.

Blazor WebAssembly optimizes payload size to reduce download times:. Blazor decouples component rendering logic from how UI updates are applied. NET Core app. UI updates are handled over a SignalR connection.

The runtime handles sending UI events from the browser to the server and applies UI updates sent by the server back to the browser after running the components.Partial Pages or Views are Razor files containing snippets of HTML and server-side code to be included in any number of pages or layouts. Partial pages can be used to break up complex pages into smaller units, thereby reducing the complexity and allowing teams to work on different units concurrently.

Partial pages are cshtml files that do not take part in routing. Therefore you can use any of the Razor templates to generate a partial page, except the Razor Page template that results in a PageModel file being created.

Partial pages are included in the calling page in a number of ways. From ASP. NET Core 2. The name attribute takes the name of the partial file, with or without the file extension. The value that you provide the name attribute is case-insensitive. The partial tag helper renders the content of the partial asynchronously thereby improving application performance. Prior to ASP.

From MVC to Razor Pages

Both methods ending with Async are for rendering partials that contain asynchronous code, although the preferred way to render separate units of UI that are dependent on asynchronous processing is to use ViewComponents. Therefore the Render methods must be called within a code block as a statement:.

The Render methods result in their output being written directly to the response, so they may result in improved performance in certain situations. However, in the majority of cases, these improvements are unlikely to be significant, so the Partial and PartialAsync methods are recommended on the basis that you should strive to minimise the number of code blocks in your Razor page. Calls to any of the rendering methods do not result in Viewstart files being executed.

Whether you use the tag helper or the Html. Partial or Html. RenderPartial methods you do not have to pass in the path of the partial file. The framework searches by walking up the directory tree from the location of the calling page looking for the file name that you pass in as long as you do not include the file extension, until it reaches the root Pages folder.

Once this has been exhausted, the formally registered locations are searched. If the page calling the partial is located in an areathe search will also start in the currently executing page's folder, and then walk up the directory tree within the area. Once the area folder structure has been exhausted, registered partial locations are searched relative to the area's folder location i.

Finally, the registered locations themselves are searched. If you provide the file name with its file extension, the framework assumes that you are passing in a relative path rooted in the folder containing the current page being executed.Comment 0.

As part of the release of. NET Core 2. One of those is the addition of a new web framework for creating a "page" without the full complexity of ASP. New Razor Pages are a slimmer version of the MVC framework and in some ways an evolution of the old ". In this article, we are going to cover some of the finer points of using ASP. It has all the same syntax and functionality. The key difference is that the model and controller code is also included within the Razor Page itself.

It enables two-way data binding and a simpler development experience with isolated concerns. Here is a basic example of a Razor Page using inline code within a functions block.

It is actually recommended to put the PageModel code in a separate file. This is more akin to how we did code behind files with ASP. NET WebForms.

This article does a good job of that with some examples. MVVM frameworks are most noted for two-way data binding of the data model. Razor Pages are perfect for simple pages that are read-only or do basic data input. MVC has been all the rage recently for web applications across most programming languages. It definitely has its pros and cons. You could argue that Razor Pages are an evolution of the old WebForms. I've been doing ASP.

NET development for about 15 years. I am very well versed in all the ASP. NET frameworks. Based on my playing around with the new Razor Pages, these are my pros and cons and how I would see using them. I don't know about you, but the first time I ever used ASP. The naming of things and the dynamically created routes caused a lot of magic that I wasn't used to.

Razor Pages doesn't have any of that "magic" and the files are more organized. You have a Razor View and a code behind file just like WebForms did. Compare that to MVC where you have separate files in different directories for the controller, view, and model. Will show more code differences later in this article.

If you have ever used an MVC framework before, you have likely seen some huge controller classes that are filled with many different actions. They are like a virus that grows over time as things get added.

With Razor Pages, each page is self-contained with its view and code organized together. This follows the Single Responsibility Principle. If you want to have different actions within your single page you need to use what is called a handler.

You would need this if your page has AJAX call backs, multiple possible form submissions, or other scenarios. You can learn more about multiple page handlers here.We also try very hard to avoid bias.

As the core team, we obviously like Vue a lot. There are some problems we think it solves better than anything else out there.

We do want to be fair and accurate though. We want to ensure not only technical accuracy, but also balance. We point out where React outshines Vue, for example in the richness of their ecosystem and abundance of their custom renderers. We acknowledge the existence of varying technical taste, and this comparison primarily aims to outline the reasons why Vue could potentially be a better fit if your preferences happen to coincide with ours.

Both React and Vue are exceptionally and similarly fast, so speed is unlikely to be a deciding factor in choosing between them. To avoid unnecessary re-renders of child components, you need to either use PureComponent or implement shouldComponentUpdate whenever you can. You may also need to use immutable data structures to make your state changes more optimization-friendly.

If that is not the case, then such optimizations may lead to inconsistent DOM state. Each component can be considered to have shouldComponentUpdate automatically implemented for you, without the nested component caveats. In React, everything is just JavaScript. This approach has its own benefits, but also comes with various trade-offs that may not seem worthwhile for every developer. Vue embraces classic web technologies and builds on top of them.

You can leverage the power of a full programming language JavaScript to build your view. This includes temporary variables, flow controls, and directly referencing JavaScript values in scope. The tooling support e. In Vue, we also have render functions and even support JSXbecause sometimes you do need that power. However, as the default experience we offer templates as a simpler alternative. For many developers who have been working with HTML, templates feel more natural to read and write.

The preference itself can be somewhat subjective, but if it makes the developer more productive then the benefit is objective. It also makes it much easier for designers and less experienced developers to parse and contribute to the codebase.

You can even use pre-processors such as Pug formerly known as Jade to author your Vue templates. With the DSL we are also able to help the user get more done with less code e. The same task can involve a lot more code when using plain JSX or render functions. On a higher level, we can divide components into two categories: presentational ones and logical ones. The percentage of these components depends on the type of app you are building, but in general we find presentational ones to be much more common.

This introduces a new component-oriented styling paradigm that is different from the normal CSS authoring process. Additionally, although there is support for extracting CSS into a single stylesheet at build time, it is still common that a runtime will need to be included in the bundle for styling to work properly.

While you gain access to the dynamism of JavaScript while constructing your styles, the tradeoff is often increased bundle size and runtime cost. The main difference between React and Vue here is that the default method of styling in Vue is through more familiar style tags in single-file components.

Single-file components give you full access to CSS in the same file as the rest of your component code.

The optional scoped attribute automatically scopes this CSS to your component by adding a unique attribute such as data-ve5b78 to elements and compiling. For large applications, both Vue and React offer robust routing solutions.

The React community has also been very innovative in terms of state management solutions e. These state management patterns and even Redux itself can be easily integrated into Vue applications. In fact, Vue has even taken this model a step further with Vuexan Elm-inspired state management solution that integrates deeply into Vue that we think offers a superior development experience.

React instead chooses to leave these concerns to the community, creating a more fragmented ecosystem. Finally, Vue offers a CLI project generator that makes it trivially easy to start a new project by featuring an interactive project scaffolding wizard.With ASP.

Microsoft named it Razor Pages, and despite being a different approach, it's still familiar in some ways. NET Applications. If you follow ASP.

NET development since the last decade, you may have already noticed how Microsoft once and while comes up with an innovation in the shape of a new development tool or framework - or even a new design pattern. Some of them have proven to be quite robust and reliable, such as ASP.

But many things have changed since the the release of ASP. NET Core 1. Microsoft rewrote ASP. NET to be a open-sourced, GitHub hosted project, and introduced the multi-platform to its web development framework for the first time.

Since the first version, ASP. NET 3. NET in And ASP. Before it, we had to deal with problems that emerged from ASP. NET MVC, We were taught to speak the language of separation of concerns while developing our web applications: data belongs to Model, presentation logic is only for Views, and every request must be handled by Controller actions, which in turn decide which View is to be rendered, along with its appropriate Model.

But while ASP. Instead, in an ASP. Now, stop for a moment and imagine how you organize your computer folders. Imagine you had some different jobs to do, which involved different files, and you had your computer folders organized not by subjects or work or topic, but by file types. And imagine you are doing multiple different jobs and, instead of grouping files by each job, you had the files for each job scattered in different folders like these:. Similarly, we can see by the image below how a typical MVC project keeps the components of a single page in a set of files scattered in many files and folders:.

This is how the Razor Page was born! NET Core 2.Last post Mar 20, PM by Mikesdotnetting. This is very annoying and concerning to me. For maintaining an app go through MVC. Why are they pushing this Razor Pages thing? I went through the Razor pages in the Core 2. This looks like a return to the old WebForms paradigm.

Why are they doing this. This is unclean and disgusting. Did Microsoft learn nothing from the Web Forms era? I try to keep the pulse on where the technology is going. And from Full Framework to.

Net Core in and at two different places. And if you went. Net Core Web Forms was no longer even available.

Six things I learnt about using ASP.NET Core’s Razor Pages

So I know I had the right pulse on the technology back in This leaves me confused and bewildered. I just cannot believe they are pushing this Web Forms looking crap with a separate. Can somebody clear this up? What is the advantage of using Razor Pages? Please don't answer with they are easier.

That is way to vague. Razor Pages encapsulates the logic int a single class. IMHO, this makes the code easier to maintain because everything is in one file. I recommend going through a tutorial. I did not like it and I did not see why Razor Pages are recommended. To your points. Third, it seems to me having all of he logic in one file would break the separation of concerns and make it more hard to maintain and test.Recently, our developer advocates authored a whitepaper that clearly lays out the state of.

In this post, we'll dive into an excerpt about ASP. NET Core. NET was first introduced — and I must say, it is an exciting time to be a developer in this space.

Changes are being made to the offerings, additions are being made to the platform, and Microsoft is making different operating systems and competing devices first-class citizens in its own ecosystem. While change in this case is good, it is a lot to keep up with.

My colleagues, John Bristowe, Ed Charbeneau, and Sam Basu, have co-authored a whitepaper that summarizes the state of our industry. NET in How the New. NET, the what and the why behind. NET Core 2. X provides. NET developers all of the tooling and framework features needed to build modern rich web applications. Here are some things to get excited about with ASP. Developers building web apps with ASP.

Opinion Time: Should Razor Pages Be the Default for ASP.NET Core Apps?

Here are your choices:. The good news for developers is. NET tooling is consistent - no matter what be your development tooling. Take a look at some of the app templates supported by 'dotnet new' CLI tooling - you'll see corresponding similar templates on doing File New in Visual Studio.

Some of the app templates are what you expect from ASP. NET - some are unexpected; we'll break things down. The ASP. NET application architectures yet.

With ASP. Each dependency in the metapackage can be referenced individually, however using the bundled approach offers additional benefits.

All the features of ASP. All package. In addition, applications using the Microsoft. All metapackage automatically take advantage of the. One of the nicest things about. Developers' choice of development OS does not matter - Windows and Mac have an identical experience.
