Mapper

Fast MySQL ORM on top of the awesome mysql-libmysqlclient driver.

The goal is to have a blazing fast ORM like dapper-dot-net for node. Mapper is faster than JAVA ORMs like JDBI (dropwizard). Much faster than any SQL-based ORM for node. No bloat.

Based off original code by didit-tech.

Installation

npm install mapper

Benchmarks

Time for 100,000 iterations alternating between insert and select. See test/bench or run make bench.

Best Practices

A simple practice without over-engineering is to main 3 distinct layers in your code:

1. Data Access Objects (DAO) - 1 to 1 mapping to database tables.
2. Models - Aggregate one or more DAO and add business logic.
3. Resources or services - Use models never DAO.

Quickstart

var Mapper = require('mapper');
var conn = { user: 'dont' , password: 'blink' , database: 'now' };
Mapper.connect(conn);

// table name only
var PostDao = Mapper.Base.extend({
  tableName: 'posts'
});

PostDao.create({ title: 'Some Title 1', body: 'Some body 1' }, function(err, results) {
  PostDao.find({ 'title.like': '%title%' }, { only: ['id', 'body'] }, function(err, post) {
    // Hooray!
  });
});
