Exploring Aurelia's Integration with ASP.NET Core Models

Recently, I've been delving into various JavaScript frameworks and made the decision to rework an ASP.Net Core MVC frontend using Aurelia. To kick things off, I utilized the SPA template.

Everything has been smooth sailing so far - I’ve integrated my DAL and BLL projects, established a connection to my database with EF Core, and successfully retrieved data for presentation in my Aurelia front end.

However, at present, my TypeScript files consist of interfaces that bear a striking resemblance to the models set up in my BLL.

Take, for example, my model:

public class staff
    {        
        [Key]
        public short StaffId { get; set; }

        [DisplayName("First name *")]
        public string FirstName { get; set; }

        [DisplayName("Family name *")]
        public string FamilyName { get; set; }

        [DisplayName("Phone")]
        public string PhoneNumber { get; set; }

        [DisplayName("Birth Date"), DisplayFormat(DataFormatString = "{0:dd MMM yyyy}", ApplyFormatInEditMode = true)]
        public DateTime? BirthDate { get; set; }  
    }

Now, let’s shift our focus to the Aurelia interface in my TypeScript file:

interface staff{
    firstname: string;   
    familyname: string;
    phone: string;
    date: date;
}

I'm keen on minimizing redundancy by directly utilizing the models. Can this be achieved through importing or injecting the models into my TypeScript files? Furthermore, is it possible to leverage annotations for table titles in HTML or formatting/validation purposes?

Many thanks,

Sylvain

Answer №1

While it might be tempting to have your aurelia models automatically generated from your backend models, doing so can actually diminish the benefits of utilizing a Single Page Application (SPA).

It is advisable to treat your backend and aurelia front end as separate applications. By keeping them distinct, any changes or rewrites in one won't directly impact the other.

To address this, consider implementing a mapping mechanism to convert your domain models to aurelia models before transmitting them over the network. You may find tools like automapper helpful in this process.

Over time, you may notice that your aurelia models start to deviate from your domain models as new features are introduced. This can lead to properties being dynamically generated during mapping, often as a combination of other properties. While it may seem redundant, avoiding direct dependencies between your frontend and backend can ultimately reduce complications and improve efficiency.
