Persist

Persist is an ultra-simple persistence framework for JavaScript. It originates from the common need for very simple, key-based persistence of objects. Its extensible nature allows quick and easy implementation of backends (known as repositories).

Currently supported repositories:

• CouchDB
• MySQL

Using Persist

Start off defining an object:

function Post(id, text)
{
    this.id = id;
    this.text = text;
}

Then, define your repository module:

var RepositoryModule = require('persist').RepositoryModule;

var module = new RepositoryModule();
module.addObjects(
{
    post:
    {
        type: Post,
        injectCrud: true, // Will inject load/save on the object
        key: 'id' // Defines which property is the object key
    }
});

module.createExports(exports); // Exports loadPost and savePost,
                               // and the augmented Post type

Then, use your persistable model:

var objects = require('objects'); // Your module

var post = new objects.Post('test', 'Hello');
post.save(function(ok)
{
    if(!ok) throw new Error('Could not save');
});

post.load('test', function(obj)
{
    if(!obj) throw new Error('Could not load');
    // Do stuff to the post
}
