1. Mongoose

Mongoose is by far one of the most popular MongoDB ORM packages for Node.js, offering a straight-forward, schema-based solution to model your application data. This includes built-in type casting, validation, query building, and business logic hooks.

const mongoose = require('mongoose')
const schema = mongoose.Schema

const blogSchema = new Schema({
  title:  String,
  author: String,
  body:   String,
  comments: [{ body: String, date: Date }],
})

const Blog = mongoose.model('Blog', blogSchema)

 

2. TypeORM

TypeORM is designed to be flexible and usable across platforms. It offers support for MongoDB, MySQL, MariaDB, PostgreSQL, CockroachDB, SQLite, MS SQL Server, Oracle, and SAP Hana. TypeORM promotes active record and data mapper patterns.

const typeorm = require('typeorm')
const EntitySchema = typeorm.EntitySchema

const UserSchema = new EntitySchema({
    name: "User",
    columns: {
        id: {
            primary: true,
            type: "int",
            generated: true
        },
        name: {
            type: "varchar"
        },
        isActive: {
            type: "boolean"
        }
    }
})

const User = typeorm.getRepository('User')

 

3. Sequelize

While Sequelize primarily functions as an ORM for SQL databases, it also provides basic support for MongoDB through sequelize-transparent.

const Sequelize = require("sequelize")

const sequelize = new Sequelize('database', 'username', 'password', {
  dialect: 'postgres'
})

const User = sequelize.define('user', {
  username: Sequelize.STRING,
  birthday: Sequelize.DATE
})

 

4. Waterline

Developed by the creators of the Sails.js framework, Waterline offers database-agnostic, data-driven APIs to work with any database including MongoDB and Node.js.

const Waterline = require('waterline')
const waterline = new Waterline()

const User = Waterline.Collection.extend({
  identity: 'user',
  connection: 'myMongo',
  attributes: {
    firstName: 'string',
    lastName: 'string'
  }
})

waterline.registerModel(User)

 

5. Caminte

Caminte provides easy-to-use, feature-rich, and middleware-agnostic object modeling for Node.js. It supports all popular databases including MongoDB.

const caminte = require('caminte')
const Schema = caminte.Schema
const schema = new Schema('mongodb', {
  host: "localhost",
  port: 27017,
  database: "test"
})

const User = schema.define('User', {
  name:     { type: schema.String },
  email:    { type: schema.String }
})
