My JSON structure is as follows:
{
items:[],
errors:[],
foundItems:9
}
One part of my program requires access to "items", while another part needs access to "errors."
To resolve this issue, I decided to create a new interface and a new class to handle the data. However, this solution isn't ideal due to the use of internal arrays. Recently, I came across a different approach using .map for mapping JSON data, and now I am curious about which method would be more efficient in my case.
When the JSON is received from the backend, all you need to do is create an interface for it.
Then, when you want to retrieve this data, you will use something like the following:
this.http.get<YOUR_INTERFACE_NAME>('/items).subscribe(...);This demonstrates an example of an HTTP get request, where the expected data type is defined by your interface.
If you are referring to the term map, you might be thinking of the rxjs operator - map. This particular operator is used to map data for asynchronous requests, such as HTTP requests, but it does not replace the necessity of creating an interface.
