chaos-orm

Chaos is an independent, persistence-agnostic layer responsible for defining entities' business logic and relationships. It allows to describe a Domain Model without any assumption about the persistence layer.

Available datasources libraries:

• MySQL
• PostgreSQL
• Sqlite

Chaos dramatically simplify the developpment of a datasources libraries by providing all persistence-agnostic logic like relationships, eager loading at the root level. The only requirement is the datasource you envisionned to use need to be able to fetch a record/document thanks to a unique identifier (i.e no composite primary key).

Install

npm install chaos-orm

Note: Require babel-polyfill as a peer dependency

Main Features

• Support eager loading
• Support nested saving
• Support external & embedded relationship

Example of syntax:

import Image from './model/Images';

co(function* () {
  // Adding a many-to-many relation
  var image = yield Image.load(123, { 'embed': 'tags' });
  image.push({ name: 'Landscape' });
  yield image.broadcast();
  image.tags.forEach(function(tag) {
    console.log(tag.get('name'));
  }); // Echoes: 'Montain', 'Black&White', 'Landscape'
});
