Node.js add created_at and updated_at in entity of typeorm

Question

I have task entity like this:

import {BaseEntity, Column, Entity, PrimaryGeneratedColumn} from "typeorm";

@Entity()
export class Task extends BaseEntity{
    @PrimaryGeneratedColumn()
    id:number;

    @Column()
    title:string

   @Column()
    description:string

}

I want to add created_at and updated_at field to this entity and populate it automatically with Node.js like Laravel framework. My database is postgres

Answer 1

Let's import first

import { CreateDateColumn,UpdateDateColumn } from "typeorm";

Add this fields and decarators in Entity

@CreateDateColumn({ type: "timestamp", default: () => "CURRENT_TIMESTAMP(6)" })
public created_at: Date;

@UpdateDateColumn({ type: "timestamp", default: () => "CURRENT_TIMESTAMP(6)", onUpdate: "CURRENT_TIMESTAMP(6)" })
public updated_at: Date;
