Is there anything wrong using the HttpClient in programmer defined classes in Angular?

Question

I wonder whether I could use the provided HttpClient in my classes. For example, should we avoid this:

export class Order {
    constructor(private http: HttpClient,...){...}
    save(){
        return this.http.post(...)
    }
}

Could we do this or should we avoid it?

Generally, we use the service to handle get and post requests data. Service is a piece of reusable code with a focused purpose. A code that you will use across multiple components in your application. — Sain Pradeep

@SainPradeep Yes, I am using services but I wondered whether one could do what I did above since each class would have its own specified post and get requests which they can use and if data is shared among classes I could put the requests for that in services — Invader

Yes, it's doable what you are asking. But think about if you should do it.

Each time class is used, a new HttpClient is constructed, using more memory and adding more complexity to your code.

How would you pass params if for some you should need to give them to httpClient? E.g the url, headers etc. You would end up refactoring the class, and then refactoring every part that uses that class.

I would not use this approach. However, if for some specific case, this class is short lived and the object (or the function) will perform specific set of actions then yes, this would be one way to do it without creating a specific service for it.

Prefer Dependency Injection if possible (the use of services for http calls).
