                This is an improvement to allow @nestjs/typeorm@8.1.x to handle CustomRepository. I won't explain it specifically, but it will help in some way. https://github.com/nestjs/typeorm/pull/1233
              
          
        
      
        
  
      
    You need to provide some classes and decorators yourself to maintain the same style as typeorm@2.x.
1. EntityRepository -> CustomRepository

@EntityRepository(UserEntity)
export class UserRepository extends Repository<UserEntity> {}
↓
	type PickProp<T, K> = K extends keyof NonNullable<T>
	? T extends undefined
	? NonNullable<T>[K] \| undefined
	: NonNullable<T>[K]
	: undefined;

	export function focusPropAtom<Store, Result, Key extends keyof NonNullable<Store>>(
	baseAtom: WritableAtom<Store, [SetStateAction<Store>], Result>,
	path: Key,
	) {
