Angular 10 model class 装饰器？

Question

I recently upgraded my project from Angular 9 to Angular 10, and now adding a decorator to classes is mandatory. I have a model class that has no decorator . It's also a TypeScript file.

Let's say I have the following model

export class Car {
   model: string;
   type: string;
   year: string;
}

Now when I run ng serve , it throws that the class has a missing decorator. It's not a component, nor a directive.

Specific error is the following:

NG2007: Class is using Angular features but is not decorated. Please add an explicit Angular decorator.

12 export class Car {
                ~~~~~~~

It even complains about classes that I use later on to be extended in some of my components. Forces me to use decorator every time.

How can I handle this issue?

Answer 1

According to the official docs, there's a way to handle these situations with base classes and stuff, is to add an empty Directive() decorator.

Here's the reference .

I made it work this way, and no complaints during ng serve now.
