getMany from a TypeORM Repository instead of just one-CodePudding

I have this code that gets a single book from the TypeORM repository and it works fine.

public async getBook(name: string) {
    const book = this.bookRepository.findOne({
      where: [{ name: name }],
    });
    return book;
  }

However, I want to implement some sort of GetManyBooks where I take in a list of names as strings use the find keyword instead of findone and return it. I thought it would be similar, but I'm having trouble finding any documentation online about this.

public async getManyBooks(name: string[]) {
    const book = this.bookRepository.find({
      where: [{ name: name }],
    });
    return book;
  }

Is there a better way I should be tackling this problem?

CodePudding user response：

You can use the in operator proivided by typeorm. Here are the docs

Also I recommend you dont use async since you dont use await and instead just return the promise itself. This will give you a Promise<Book[]>.


import { In } from "typeorm";

// docs example

const loadedPosts = await connection.getRepository(Post).find({
    title: In(["About #2", "About #3"]),
});


// In your case

public getManyBooks(name: string[]) {
    return this.bookRepository.find({
        where: {name: In(name)},
    });
}
