TypeORM's Soft Delete feature allows marking records as deleted instead of physically deleting them:

1. **Enable soft delete**:
   Use the @DeleteDateColumn() decorator in the entity:
   ```typescript
   @Entity()
   export class User {
     @DeleteDateColumn()
     deletedAt?: Date;
   }
   ```

2. **Soft delete operations**:
   ```typescript
   await userRepository.softRemove(user);
   // or use
   await userRepository.softDelete(userId);
   ```

3. **Restore soft-deleted records**:
   ```typescript
   await userRepository.restore(userId);
   ```

4. **Exclude soft-deleted records when querying**:
   By default, the find() method automatically excludes soft-deleted records.

5. **Include soft-deleted records**:
   ```typescript
   userRepository.find({ withDeleted: true });
   ```

6. **Query only soft-deleted records**:
   ```typescript
   userRepository.find({ withDeleted: true, where: { deletedAt: Not(IsNull()) } });
   ```

The advantage of soft delete is that it preserves data history, making it easier to recover data and conduct audits.
