Motivation​

Suppose you work on ASP.NET Core web application that solves some business-related tasks. You know, a few forms where users enter their data and get some reports. Although such a project may not require any complex logic on the client, you still probably need to write some JavaScript code to make user interaction with your application more convenient and enjoyable. For example, you may need a simple prompt popup on item deletion since it's not quite right to use a separate page for that. Or, you want to do client-side validation. Or ... it really can be any other client-side task, you name it.

Implementing CRUD operations in your ASP.NET Core application can be a very tedious and time-consuming task. EasyData helps to add all necessary functionality (and even more) in a matter of minutes.

Problem​

One of the first tasks for most business applications is to implement CRUD (Create, Read, Update, Delete) operations for the main entities the app works with.

Every developer faces the following problems as part of solving the task:

• The creation of CRUD pages and forms is very boring and time-consuming. Believe me, I’ve been there a lot of times.

• If you do it manually, it can be very slow and error-prone (missed fields, forgotten validators, etc).

• Of course, you can use the scaffolding tool provided by Visual Studio. However, it’s also not a quick process either, because you need to run that tool for each model class. As a result, you get many .cs and .cshtml files, which you'll have to edit manually if something in the default behavior or appearance doesn't suit your needs. In the event of changes in the model classes, you'll need to update those generated controllers and pages manually or regenerate the code and forms from scratch for each affected model class.

• Moreover, even the built-in scaffolding doesn't provide some important, often essential functions such as paging or search.

Introduction​

When you start learning a programming language, one of your first exercises will probably be to write a “Hello World” application to figure out the basic concepts. This exercise works well if you’re writing a simple console program that will only print out the greetings on the screen.

However, once you move onto learning to write web apps using a new framework, such as ASP.NET Core, such a simple code is not enough — partially because web apps are more complex. And also because, right off the bat, the tools and frameworks used for writing web apps try to introduce advanced techniques and approaches for building and maintaining them once they scale.
