the best I found for this purpose is the class-transformer. github.com/typestack/class-transformer

That's how you use it:

Some class:

export class Foo {

    name: string;

    @Type(() => Bar)
    bar: Bar;

    public someFunction = (test: string): boolean => {
        ...
    }
}


import { plainToClass } from 'class-transformer';

export class SomeService {

  anyFunction() {
u = plainToClass(Foo, JSONobj);
 }

If you use the @Type decorator nested properties will be created, too.
