Tips for creating a Sequelize table with TypeScript the right way

My current challenge involves:

interface PersonI {
    id?: number | null,
    firstName: string,
    lastName: string
}


@Table(
    {
        tableName: 'person',
        timestamps: true
    }
)
class Person extends Model implements PersonI{

    @AutoIncrement
    @PrimaryKey
    @Column(INTEGER)
    id!: number

    @AllowNull(false)
    @NotEmpty
    @Column(STRING)
    firstName!: string

    @AllowNull(false)
    @NotEmpty
    @Column(STRING)
    lastName!: string

}

Despite my efforts, I keep encountering this error message: TypeError: Class constructor Model cannot be invoked without 'new'; What could be causing this issue?

Answer №1

import { Model, Column, Table, AutoIncrement, PrimaryKey, NotEmpty, AllowNull } from "sequelize-typescript";

@Table(
    {
        tableName: 'user_details',
        timestamps: true
    }
)
export class UserDetails extends Model<UserDetails>{
    @AutoIncrement
    @PrimaryKey
    @Column
    id!: number

    @AllowNull(false)
    @NotEmpty
    @Column
    fullName!: string

    @AllowNull(false)
    @NotEmpty
    @Column
    password!: string
}

No interface required for this model.
