Installation

$ npm install --save @m92/mongo-odm

Environment Variables

The following environment variables need to be set to work with this package:

##### Mongo Config
export MONGO_HOSTS=
export MONGO_DBNAME=
export MONGO_USER_AUTH=false
export MONGO_USERNAME=
export MONGO_PASSWORD=
export MONGO_REPLICASET=
export MONGO_REPLICASET_COUNT=0
export MONGO_READ_PREFERENCE=
export MONGO_SSL_ENABLED=false
export MONGO_SSL_VALIDATE=false
export MONGO_PEM_PATH=
export MONGO_POOL_SIZE=5

Note: Do not export variable 'MONGO_READ_PREFERENCE' if no value is to be set.


Connecting to MongoDB

MongoDB needs to be connected before the 'MongoModel' methods can executed. The connection can be established as shown below:

import mongoConnect from '@m92/mongo-odm/mongoConnect'
await mongoConnect()

Creating a Collection Schema

import mongoSchemaWrapper from '@m92/mongo-odm/mongoSchemaWrapper'

const CollectionSchemaObject = {
    // Schema Properties as defined by mongoose Schema Class
}
const options = {}

const CollectionSchema = mongoSchemaWrapper(CollectionSchemaObject, options)
export default CollectionSchema

mongoSchemaWrapper() returns an instance of mongoose Schema Class.

Note: The 'options' object properties to be used is as defined by mongoose Schema Class. By default, mongoSchemaWrapper adds 'timestamps: true' option which can be overriden if needed. You may avoid passing the 'options' object if no extra options are required for a given Schema.


Using mongoose Schema Class

import { Schema } from '@m92/mongo-odm/mongoose'

const SubDocumentSchema = new Schema({
  // Schema Properties as defined by mongoose Schema Class
})

export default SubDocumentSchema

Creating a Collection Model

import MongoModel from '@m92/mongo-odm/MongoModel'
import CollectionSchema from './CollectionSchema.mjs'

const CollectionODM = new MongoModel('Collection', CollectionSchema)
export default CollectionODM

Properties of MongoModel Instance

Properties Description
CollectionODM.ModelName Name of the Model
CollectionODM.Schema mongoose Collection Schema
CollectionODM.MongooseModel mongoose Model instance
