Avoid code duplication when using a strongly typed model

Summary:

How can I avoid duplicating the schema definition if I want a strongly typed model? It can become areal nightmare if your schema has heaps of properties.

Schema

const userSchema = new dynamoose.Schema({
	"id": String,
	"name": String,
	"age": Number
})

class User extends Document {
	// <--- DRY? --->
	id: string;
	name: string;
	age: number
	// <------------>
}

Model

const UserModel = dynamoose.model<User>("User", userSchema);

Environment:

Node.js version: v12.19.0 NPM version: (npm -v): 6.14.8 Dynamoose version: 2.4.1

@RickvdP I did see that recently. Sadly, we just need more support to make it happen.

v3, still has a bit to go before release. Tho we are getting closer.

Yes. I think v4 support for this using TypeScript Decorators would be great along with bringing TypeScript out of beta. Seems like a great idea.

@fishcharlie I agree too, but I think there is no easy way to do that yet, however I will definitely spend sometime on it later. here is some discussion about this topic https://stackoverflow.com/questions/45771307/typescript-dynamically-create-interface
