Hi @zhuravlevma , Thank you for sharing this amazing piece of work with us. You have helped me crack unit of work with Prisma.

I opened this issue to let you know that your first approach with cls-hooked also works with a few modifications. You would need to add nestjs-cls and enable it globally and we can easily share the prisma transaction object without the need to pass it as an arg into each repository.

I'm sharing some of the code here for your reference.

export abstract class UnitOfWork { abstract runInTransaction<R>(fn: () => Promise<R>): Promise<R>; }

`import { ClsService, Terminal } from "nestjs-cls";

@Injectable({ scope: Scope.REQUEST })
export class PrismaTransactionScope implements UnitOfWork {
constructor(
private readonly prisma: PrismaService,
private readonly cls: ClsService<{
prisma: Terminal<Prisma.TransactionClient>;
}>,
) {}

get manager() {
return this.cls.get("prisma");
}

async runInTransaction(fn: () => Promise): Promise {
return await this.prisma.$transaction(async (manager) => {
this.cls.set("prisma", manager);
return await fn();
});
}
}`

`import { ClsModule } from "nestjs-cls";

@module({
imports: [
ClsModule.forRoot({ global: true, middleware: { mount: true } }),
],
controllers: [AppController],
})
export class AppModule {}`

Kindly let me know if it works for you.
