Create your entity models.
In a departure from classic @ngrx/entity models, each model in your application should be defined as a class (see note below). Here is an example of a Customer
model:
Next we need to import the Key
decorator. This is used to specify the property in your model that is the unique identifier. Decorate the id
property, which is the unique identifier for Customer
model. Read more about entity keys in the advanced documentation.
Note that the model must be a class and not an interface. This is because interfaces are a compile-time only feature of TypeScript, while classes are a native runtime construct in JavaScript.
