What is the most efficient way to transfer data to another page without having to repeatedly retrieve it from a

Looking for a way to pass additional data to another page when clicking on an item.

I attempted to extend the father class to the child class, but it significantly slowed down the process due to the frequent class calls.

This application is a dashboard with external widgets imported into the HTML template, all of which require access to the same data.

I considered using a container to hold all backend calls, possibly through a module, but have not been successful. Any suggestions on how to achieve this?

My recommendation would be to consider implementing a state management library such as ngrx or ngxs. By utilizing one of these tools, you can establish a centralized state in your application, making it simpler to access and share data across different components.

In Angular, services play a crucial role in facilitating data exchange between components. However, when dealing with components that have a parent-child relationship, the @Input() decorator comes in handy.

Maryannah believes that constructing a "cache" is possible. In a typical service function, it operates like this:

getData()
{
    return httpClient.get(....);
}

You have the option to use a variable to store the result of httpClient

data:any[]
getData()
{
    if (!data)
       return httpClient.get(....).pipe(tap(result=>{
          this.data=result;
       }))
    return of(this.data)
}

Therefore, upon the initial subscription to the service to call the server, subsequent subscriptions will provide an observable of the already fetched data

Looking for a solution to your problem? The Rx/js BehaviorSubject might just be the answer. In order to follow good Angular practices, it's recommended to keep logic out of components that isn't directly related to the view. Instead, this logic should be moved to services. The purpose of the BehaviorSubject is to hold the value that needs to be shared with other components. By subscribing to this data, components can easily access the value stored in the BehaviorSubject without the ability to modify it.
