What’s the difference between remove and delete?

Question

For example, I have a TypeORM entity Profile:

@Entity() class Profile {      @PrimaryGeneratedColumn()     id: number;      @Column()     gender: string;      @Column()     photo: string;      @OneToOne(type => User, { cascade: true })     @JoinColumn()     user: User; } 

And I’m not sure which one should I use to delete a user profile?

Profile.remove(profile) Profile.delete(profile) 

What is the difference between the remove and delete methods in TypeORM?

Answer 1

From Repo:

• remove - Removes a given entity or array of entities. It removes all given entities in a single transaction (in the case of entity, manager is not transactional).

Example:

await repository.remove(user); await repository.remove([     category1,     category2,     category3 ]); 

• delete - Deletes entities by entity id, ids or given conditions:

Example:

await repository.delete(1); await repository.delete([1, 2, 3]); await repository.delete({ firstName: "Timber" }); 

As stated in example here:

import {getConnection} from "typeorm";  await getConnection()     .createQueryBuilder()     .delete()     .from(User)     .where("id = :id", { id: 1 })     .execute(); 

Which means you should use remove if it contains an array of Entities.

While you should use delete if you know the condition.

Additionally, as @James stated in comment Entity Listener such as @BeforeRemove and @AfterRemove listeners only triggered when the entity is removed using repository.remove.

Similarly, @BeforeInsert, @AfterInsert, @BeforeUpdate, @AfterUpdate only triggered when the entity is inserted/updated using repository.save.
