@mayajs/mongo

Mongodb Module and Service

Description

A MayaJS module and service that deals with Mongodb drivers. It uses mongoose as its core dependency to communicate with the database.

Installation

npm i @mayajs/mongo

Quick Start

MayaJS uses custom modules to add functionality on its core. You can use MongoDbModule and import in on any MayaJS module in your project.

import { MongoDbModule } from "@mayajs/mongo";
import { Schema } from "mongoose";

// Define schema for mongoose
const User = new Schema({
  name: String,
  email: String,
  password: String,
});

const mongodbOptions = {
  connectionString: "your-mongodb-connection-string",
  name: "your-collection-name",
  options: {
    // Any mongoose options can be used here
    // i.e. useUnifiedTopology: true, useNewUrlParser: true, useFindAndModify: false
  },
  schemas: [
    {
      name: "User", // Name of model
      schema: User, // Mongoose Schema
    },
    ,
  ],
};

@Module({
  imports: [MongoDbModule.forRoot(mongodbOptions)],
})
class CustomModule {}

Usage

To use mongodb inside your controller you will need to import MongoDbServices. MongoDbServices provides set of functionality to access, manipulate and interact with mongodb.

Accessing a Collection

MongoDbServices provides a database function to access a specific collection in mongodb.

import { MongoDbServices } from "@mayajs/mongo";

@Controller()
class UsersController {
  // Inject MongoDbServices in a controller
  constructor(private mongo: MongoDbServices) {}

  sample() {
    // Get specific collection in mongodb
    const db = this.mongo.database("your-collection-name");
  }
}

Accessing a Model

To access a model you will need first the get the collection instance that we get from the above example. On the db instance you can access the model object like seen below.

sample() {
  // Get specific collection in mongodb
  const db = this.mongo.database("your-collection-name");

  // Get specific model instance
  const model = db.instance.model("your-model-name");
}

This model instance is based on Mongoose Model. All of mongoose functionality is available for this model instance.
