Recommendations for organizing code with respect to models in Angular using TypeScript

Within my C# backend, I structure my entities and entity lists using classes. Any needed functions or methods are simply added to the corresponding class.

On the contrary, in Angular/TypeScript examples, models are typically defined as interfaces. This raises the question of how to effectively organize the functions that interact with these interface objects.

Currently utilizing NgRx, there is a temptation to integrate this code within the selectors. However, I am wary that this approach may lead to cluttered and disorganized code.

Answer 1

Answer №1

The guidelines remain consistent with C#. The structures do not necessarily have to be interfaces; they can also function as a class if additional functionality is required.

For instance,

export class Person {
  firstName: string;
  lastName: string

  get fullName(): string {
    return `${firstName} ${lastName}`;
  }
}

However, when utilizing NgRx, it is advised against storing objects like this in the store - hence why most opt for interfaces.

In such situations, I recommend creating a new file specifically for "selectors," where you can house the logic for retrieving full names. This makes it easier to test your business logic as well.

In Angular/typescript/(modern) javascript, utilizing classes and the class keyword is recommended. It is advisable to use an interface to store data (similar to DTO/POCOs in c#), and when modeling behavior, opt for a class.

Additionally, if you aim to segregate logic, delegate that to services, akin to server-side frameworks like .net and spring.
