TypeORM - findAll method to find all articles of an user

Question

I want find all articles of one user from TypeORM package.

On Sequelize, I have this:

async findAllByUser(userUuid: string, findOptions: object): Promise<Article[]> {
    return await Article.findAll<Article>({
        include: [{
            model: User,
            where: {
                uuid: userUuid
            }
        }]
    });
}

I'd like an alternative for TypeORM.

Solution

You can join if the relationship was defined in model

export class Article {
    /// ... other columns

    @ManyToOne(type => Author, author => author.articles)
    author: Author;
}

There are two way to query: find* method or QueryBuilder

// find*

createConnection(/*...*/).then(async connection => {

    /*...*/
    let articleRepository = connection.getRepository(Article);
    let articles = await articleRepository.find({ relations: ["author"] });

}).catch(error => console.log(error));

// Query Builder
const articles = await connection
    .getRepository(Article)
    .createQueryBuilder("article") 
    .leftJoinAndSelect("article.author", "user")
    .getMany();
