I am currently working on setting up a oneToMany, ManyToOne relation method and here is my progress so far (pseudocode provided below). I am using Typegoose which is essentially Mongoose with types. If you are unfamiliar with it, that's okay because this discussion is more about architecture. Specifically, I want to address the "createBook" method. As you can see in the code snippet, I am using nested "await" calls which can be inefficient. I could potentially use promises and end the method by calling
Promise.all(bookQuery, authorQuery)class Author extends Typegoose {
@prop()
fullName: string;
@prop({ ref: Book, default: [] })
books: Ref<Book>[];
}
class Book extends Typegoose {
@prop()
title: string;
@prop({ ref: Author })
author: Ref<Author>;
}
async createBook(title, authorId): Promise<Book> {
const book = await new this.bookRepository({
title,
author: ObjectId(authorId)
}).save();
await this.authorRepository.updateOne(
{ _id: authorId },
{ $push: { books: Types.ObjectId(book.id) } }
);
return book;
}
