[SOLVED] Best way to assign default entity values in NestJS

Best way to assign default entity values in NestJS

I am new to NestJS and prefer to always work with Typescript's "strict": true compiler option. However when I do this a few of the auto-generated files throw errors due to no default values being set. For example I have this Entity file

organization.entity.ts

import { Column, Entity, PrimaryGeneratedColumn } from 'typeorm';
import { OrganizationTypeEnum } from './organization-type.enum';

@Entity({ name: 'Organization' })
export class OrganizationEntity {
  @PrimaryGeneratedColumn('uuid')
  id: string;

  @Column()
  name: string;

  @Column({ default: null })
  logoUrl: string | null;

  @Column({ default: OrganizationTypeEnum.COBRAND })
  type: OrganizationTypeEnum;
}

Which gives an error like this for each property

Property id has no initializer and is not definitely assigned in the constructor.

What is the proper convention here? Should I:

assign a value directly like id: string = '';
give it a non-null assertion like id!: string;

Or is there something else I should do instead? Assigning a value feels wrong because I don't think that value would ever be used anywhere and it's potentially misleading. Perhaps strigc mode in typescript isn't worth it here?

Solution

The best solution would be to set the tsconfig option strictPropertyInitialization to false, for the sake of both your DTOs and your entities
