Why is razor pages the recommended approach to create a web ui in asp net core

Introduction

When it comes to creating a web UI in ASP.NET Core, there are several approaches available. One of the recommended approaches is using Razor Pages. In this article, we will explore why Razor Pages is the recommended approach and provide examples to illustrate its benefits.

What are Razor Pages?

Razor Pages is a new feature introduced in ASP.NET Core that makes it easier to build web UIs. It is a page-based programming model that allows developers to define the UI and the associated code in a single file. This approach simplifies the development process and improves the maintainability of the code.

Benefits of Razor Pages

There are several benefits of using Razor Pages to a web UI in ASP.NET Core:

1. Simplified Development

Razor Pages provide a simplified development by combining the UI and the code in a single file. This eliminates the need to create separate files for the UI and the code-, making it easier to understand and maintain the code.

2. Improved Productivity

With Razor Pages, developers can quickly build web UIs without having to write a lot of boilerplate code. The built-in conventions and tag helpers simplify common tasks, such as form handling and data binding, reducing the amount of code that needs to be written.

3. Separation of Concerns

Razor Pages promote the separation of concerns by allowing developers to define the UI and the code in separate sections within the same file. This makes it easier to understand and modify the code, as each section focuses on a aspect of the .

4. Testability

Since Razor Pages follow the MVC pattern, the code can be easily unit tested. The separation of concerns and the ability to mock dependencies make it easier to write tests and ensure the correctness of the code.

: Creating a Razor Page

Let's take a look at an example to illustrate how to create a Razor Page in ASP.NET Core:


@page
@model IndexModel

Welcome to Razor Pages!

This is a simple Razor Page.

@code { public class IndexModel : PageModel { public void OnGet() { // Code to when the page is requested } } }

In this example, we define a Razor Page with the @page directive, specifies that this file represents a Razor Page. The @model directive is used to specify the model class associated with the page.

The HTML markup and the code are defined within the same file. The @code directive is used to define the code section, where we can define and associated with the page.

In the OnGet method, we can write the code that needs to be executed when the page is requested. This method can be used to fetch data from a database, perform calculations, or any other logic required for the page.

Conclusion

Razor Pages provide a recommended approach to create a web UI in ASP.NET Core. With its simplified development experience, improved productivity, separation of concerns, and testability, Razor Pages make it easier to build and maintain web UIs. By combining the UI and the code in a single file, developers can quickly create web UIs without writing a lot of boilerplate code.
