ViewModel Best Practices

ViewModel Best Practices: Simplify Your MVC Structure 😎📦

Are you feeling a bit lost when it comes to organizing your ViewModel classes in an MVC project? Don't worry, you're not alone! Many developers struggle with this concept and finding consistent guidance can be a challenge 😕. But fear not, in this blog post, we'll go over some best practices and provide easy solutions to help you breeze through this dilemma! Let's dive in! 🏊‍♂️

1️⃣ One Class/File Conundrum

You mentioned that you prefer having one class/file in your project. But what about the ViewModel when it's simply used to transfer data from a controller to a view? 🤔 Well, that's actually a common scenario! In small projects, it's acceptable to keep your ViewModel within the Controller file itself. This simplifies the project structure, making it easier for newcomers to understand. 😌

For example, let's say we have a ProductController that handles product-related logic. Your ViewModel class, ProductViewModel, can live inside the ProductController file like this:

public class ProductController : Controller
{
    // ProductController code...

    public IActionResult Index()
    {
        // Create an instance of your ViewModel
        var viewModel = new ProductViewModel()
        {
            // Populate the ViewModel with necessary data
        };

        return View(viewModel);
    }
    
    public class ProductViewModel
    {
        // Properties and methods specific to the view go here
    }
}

By keeping your ViewModel inside the ProductController file, you maintain a logical connection between the controller and its associated data. 👍

2️⃣ Directory Dilemma

Now, what if you're working on a larger project and prefer to separate your files to maintain a structured project directory? In this case, it's recommended to create a separate folder for your ViewModels. This keeps things organized and ensures scalability as your project grows. 📂

For instance, you can create a directory called ViewModels in your project's root directory and place your ViewModel classes inside it. Your directory structure might look like this:

- Controllers
  - HomeController.cs
  - ProductController.cs
- Models
  - Product.cs
  - Order.cs
- Views
  - Home
  - Product
- ViewModels
  - ProductViewModel.cs
  - OrderViewModel.cs

By separating your ViewModel classes in the ViewModels folder, you can easily locate and manage them as your project evolves. 🧐
