Prisma Model to TypeORM Entity example

Demonstrates converting a Prisma model with autoincrement primary key, unique email, nullable name, and one-to-many relationship into a decorated TypeORM TypeScript entity class.

Sample Prisma Schema Source 
model User {
  id Int @id @default(autoincrement())
  email String @unique
  name String?
  posts Post[]
}
Generated TypeORM Entity Processed 
@Entity()
export class User {
  @PrimaryGeneratedColumn()
  id: number;

  @Column({ unique: true })
  email: string;

  @Column({ nullable: true })
  name: string | null;

  @OneToMany(() => Post, (post) => post.author)
  posts: Post[];
}

Frequently Asked Questions

How are Prisma relation attributes mapped to TypeORM?
Virtual Prisma relation fields (such as posts Post[] or user User @relation(...)) are converted into TypeORM relation decorators: array fields become @OneToMany(() => Target, inverse) and single relation fields become @ManyToOne(() => Target, inverse) with @JoinColumn().
How are primary keys and autoincrements handled?
Prisma fields marked with @id @default(autoincrement()) map to TypeORM @PrimaryGeneratedColumn(), UUID defaults map to @PrimaryGeneratedColumn('uuid'), and non-generated IDs map to @PrimaryColumn().
Is my database schema uploaded to any server?
No. All parsing and TypeScript code generation executes 100% client-side in your browser memory. No schema data or network requests are ever transmitted.
