How to make combination of two columns unique

[hexdecimal16]

I have an entity

import { Field, ID, ObjectType, Root } from "type-graphql";
import { BaseEntity, Column, Entity, PrimaryGeneratedColumn } from "typeorm";

@ObjectType()
@Entity()
export class News extends BaseEntity {

    @Field(() => ID)
    @PrimaryGeneratedColumn("uuid")
    newsId: string;

    @Field()
    @Column({ type: "text" })
    title: string;

    @Field()
    @Column({ type: "text" })
    description: string;

    @Field()
    @Column({ type: "text", nullable: true, default: 'https://icon-library.com/images/generic-user-icon/generic-user-icon-19.jpg' })
    imageUrl: string;

    @Field()
    @Column({ type: "text" })
    url: string;

    @Field()
    @Column({ type: "timestamp", default: () => "CURRENT_TIMESTAMP", nullable: true })
    date: Date;

    @Field()
    ago(@Root() parent: News): string {
        const time = new Date().getTime() - parent.date.getTime();
        const days = Math.floor(time / (1000 * 60 * 60 * 24));
        const hours = Math.floor(time / (1000 * 60 * 60));
        const minutes = Math.floor(time / (1000 * 60));
        const seconds = Math.floor(time / (1000));
        if (days > 0) {
            return `${days} days ago`;
        } else if (hours > 0) {
            return `${hours} hours ago`;
        } else if (minutes > 0) {
            return `${minutes} minutes ago`;
        } else if (seconds > 0) {
            return `${seconds} seconds ago`;
        } else {
            return "Just now";
        }
    }
    
}

I want combination of title and date to be unique. How to achieve it?

I think you should ask on TypeORM repo 😛
