Issue with declaring an interface in Angular 2/4

When working with Angular, it is common to declare an interface before parsing JSON data retrieved from a server. While this approach works well with small JSON structures, it becomes challenging when dealing with large files containing hundreds of key-value pairs.

What alternative options are available in such situations?

Answer №1

It's not necessary to create an Interface. However, opting to do so allows you to take advantage of the benefits offered by a strongly-typed language like typescript.

If you choose not to create an interface, you can simply use "any," but you will still need to recall the specific elements within the JSON in order to retrieve its values.
