And more...

With TypeORM, your models look like this:

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

@Entity()
export class User {
    @PrimaryGeneratedColumn()
    id: number

    @Column()
    firstName: string

    @Column()
    lastName: string

    @Column()
    age: number
}

And your domain logic looks like this:

const userRepository = MyDataSource.getRepository(User)

const user = new User()
user.firstName = "Timber"
user.lastName = "Saw"
user.age = 25
await userRepository.save(user)

const allUsers = await userRepository.find()
const firstUser = await userRepository.findOneBy({
    id: 1,
}) // find by id
const timber = await userRepository.findOneBy({
    firstName: "Timber",
    lastName: "Saw",
}) // find by firstName and lastName

await userRepository.remove(timber)

Alternatively, if you prefer to use the ActiveRecord implementation, you can use it as well:

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

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

    @Column()
    firstName: string

    @Column()
    lastName: string

    @Column()
    age: number
}

And your domain logic will look this way:

const user = new User()
user.firstName = "Timber"
user.lastName = "Saw"
user.age = 25
await user.save()

const allUsers = await User.find()
const firstUser = await User.findOneBy({
    id: 1,
})
const timber = await User.findOneBy({
    firstName: "Timber",
    lastName: "Saw",
})

await timber.remove()
