A simple ActiveRecord like nodejs module for mysql



A simple ActiveRecord like nodejs module for mysql database.

It supports has_many and belongs_to relationship.

You can find and find_by* each field name.

Important: it works synchronously.


This module is based on Sannis's node-mysql-libmysqlclient.

Mysql_node_orm adds some simple features as ActiveRecord does.

I'm working on it and I would to expand it also with your help.

So, do not hesitate to contact me for any question or doubts

My mind is open for any collaboration ;)


For installing this module use

npm install mysql_node_orm


See files in the spec folder for examples


Having a DB as ActiveRecord on Rails wants. You can able to perform select insert and update using Models like instances.

var DataType = require('mysql_node_orm/lib/datatype');
var Adapter = require('mysql_node_orm');
var Author = Adapter.declare('Author', {
  has_many: ['Book'],
  destroy: [ 'Book' ],
  fields: {
    name: {
      type: DataType.String,
      unique: true
    age: {
      type: DataType.Int
Book = Adapter.declare('Book', {
  belongs_to: ['Author'],
  fields: {
    name: {
      type: DataType.String
    pages_number: {
      type: DataType.Int
    foo: function(bar){
      return 'foobar ' + bar;
    test: function(){
      return 'test method'
var author = Author.find( 1 );
var books = author.books
book = new Book({
  name: 'Foobar book'
book.pages_number = 1024;
books.push( book ); true );

Adapter(host, user, pwd, database, port)

  • it is the main class
var Adapter = require('mysql_node_orm');
var adapter = new Adapter( 'localhost', 'root', 'password', 'db_name', 3306);

DataType (used to declare the fields)

  • DataType.String # the VARCHAR type
  • DataType.Int # the INT type
  • DataType.Boolean # the TYNINT type

(tmporarly incompleted)

// To use the datatype 
var DataType = require('mysql_node_orm/lib/datatype')


(Static methods)

  • Model.find( id /* as NUM */ ) # returns the instance of the model if found. Otherwise null
  • Model.find( 'all' ) # returns an Array instance contaning all model found by performing the select. Empty array if no record found
  • Model.find( 'first' ) # returns the instance of the model representing the first matched record if found. Otherwise null
  • Model.find_by( where, options, limit ) #### where (Object)
    where = {
      field_foo_name: field_foo_value,
      field_bar_name: field_bar_value,

options (Object)

options = {
  includes: ['table_foo_name', 'table_bar_name'],
  joins: {
    table_foo_name: {                       // INNER JOIN table_foo_name
      field_bar_name: {                     // ON  field_bar_name
        table_xxxx_name: 'field_xxxx_name'  // = table_xxxx_name.field_xxxx_name

limit (Number) Used as LIMIT sql condition

  • Model.find_by_foo_field_name( value ) # return an Array containing the result of select * from table_foo_name where FOO_FIELD_NAME = VALUE. A single Model instance if field is declared as unique


What I'm going to do:

  • has_many_through relations

  • DataType conversion

  • migrations

  • More documentation is coming... ;)


  • Delete model and its dependencies
  • Implement events
  • Fields validation
