Many to many relationship in NestJS + TypeORM - custom names for resultant table?

I have a User and Product table, many to many relationship with:

@Entity('User')
  export class User {
  ...
    @ManyToMany(() => Product)
    @JoinTable({ name: 'UserProduct' })
    Products: Product[];
}

which results as expected in a generated UserProduct table, with 2 columns: userId, productId - how do I custom name these to stick with my conventions? i.e. UserId, ProductId

Have you looked at the TypeORM docs for @JoinTable? It seems that they allow you to override the standard naming convention with your specific column naming requirements using joinColumn.

I think you want something like this:

@JoinTable({
    name: "UserProduct",
    joinColumn: {
        name: "UserId",
        referencedColumnName: "id"
    },
    inverseJoinColumn: {
        name: "ProductId",
        referencedColumnName: "id"
    }
})
