@nest-extended/mongoose

This package provides powerful Mongoose integrations for the NestExtended ecosystem, offering a robust service layer with built-in pagination, filtering, and soft delete capabilities.

Key Features

• NestService: A generic service class (NestService<DTO, Document>) that provides:
  • CRUD Operations: _find, _get, _create, _patch, _remove.
  • Advanced Querying: Support for $regex, $or, and standard MongoDB operators.
  • Pagination: Built-in pagination logic using skip and limit.
  • Soft Delete: Configurable soft delete support (requires @nest-extended/core integration).
• Utilities:
  • ensureObjectId: Helper to validate and convert strings to MongoDB ObjectIds.
  • nestify: Query helper for applying filters, sorting, and pagination.

Usage

NestService

Extend NestService to create a service with full CRUD capabilities.

import { NestService } from '@nest-extended/mongoose';
import { InjectModel } from '@nestjs/mongoose';
import { Model } from 'mongoose';
import { Cat, CatDocument } from './schemas/cat.schema';

@Injectable()
export class CatsService extends NestService<Cat, CatDocument> {
  constructor(@InjectModel(Cat.name) catModel: Model<CatDocument>) {
    super(catModel);
  }
}

Querying

You can use the _find method with query objects:

const results = await this.catsService._find({
  name: { $regex: 'kitty', $options: 'i' },
  age: { $gt: 5 },
  $sort: { createdAt: -1 },
  $limit: 10
});
