strongoose-nest v0.1.0

Strongoose NestJS Module

A module for integrating Strongoose models into NestJS. The implementation is completely based on @nestjs/mongoose.

Strongoose builds Mongoose models using Typescript classes and a few decorators.

Installation

Before installing, make sure you have NestJS, Mongoose and Reflect Metadata installed, all listed as peerDependencies.

$ npm install --save strongoose-nest

Usage

If you've ever used Mongoose in nest, this should feel pretty familiar. In changes in very few details.

First make the connection to the database in your main module (usually app.module.ts):

import { Module } from '@nestjs/common'
import { StrongooseModule } from '@strongoose'

@Module({
  imports: [StrongooseModule.forRoot('mongodb://localhost:27017/strongoose', { useNewUrlParser: true })]
})
export class ApplicationModule {}

Create a Strongoose model class:

import { Strongoose, field } from 'strongoose'

export class Cat extends Strongoose {
  @field()
  name: string
}

Supposing there's a CatModule that handles cat stuff, import the new model:

import { Module } from '@nestjs/common'
import { StrongooseModule } from '@strongoose'
import { Cat } from './models/cat.model.ts'
import { CatService } from './services/cat.service.ts'

@Module({
  imports: [StrongooseModule.forFeature(Cat)],
  providers: [CatService]
})
export class CatModule {}

Finally, inject the model as a dependency into the service. This could very well be a repository or any patterns you're using:

export class CatService {
  constructor(
    @InjectModel(Cat) private readonly cat: ModelType<Cat>
  ) {}

  async findById(id: string) {
    return await this.cat.findById(id).exec()
  }
}
