Column data types

Next, let’s fix our data types. By default, string is mapped to a varchar(255)-like type (depending on the database type).Number is mapped to a integer-like type (depending on the database type).We don’t want all our columns to be limited varchars or integers.Let’s setup correct data types:

import {Entity, Column, PrimaryGeneratedColumn} from "typeorm";
@Entity()
export class Photo {
    @PrimaryGeneratedColumn()
    id: number;
    @Column({
        length: 100
    })
    name: string;
    @Column("text")
    description: string;
    @Column()
    filename: string;
    @Column("double")
    views: number;
    @Column()
    isPublished: boolean;
}

Column types are database-specific.You can set any column type your database supports.More information on supported column types can be found here.
