Create Models & Queries

foal generate entity my-entity

Entities

Simple models are called entities in TypeORM. You can generate one with the above command.

Example:

import { BaseEntity, Column, Entity, PrimaryGeneratedColumn } from 'typeorm';
@Entity()export class Product extends BaseEntity {
  @PrimaryGeneratedColumn()  id: number;
  @Column()  name: string;
  @Column()  price: number;
}

The class Product represents the database table and its instances represent the table rows.

In FoalTS, entity files should always be named with the extension .entity.ts. This way the CLI can find the entities when automatically generating migrations.

Using Entities

const product = new Product();product.name = 'chair';product.price = 60;await product.save();
const products = await Product.find();// find by id:const firstProduct = await Product.findOne(1);const chair = await Product.findOne({ name: 'chair' });
await chair.remove();

Queries

const firstProduct = await Product  .createQueryBuilder('product')  .where('product.id = :id', { id: 1 })  .getOne();
