Nanoid Object Modeller

Don't panic!

Nanoid makes it easier to build applications with Couchdb. It removes the repeatable cruft and makes working with Couchdb as fun as it should be.

4 easy steps to installation

1. Download

   npm install nanoid

2. Connect to database

   var Model = require('nanoid') Model.create_connection("my_database");

3. Define a model

   Model.define('User', { name: String surname: {type: String, default: "Rambo"} })

Defining a model

var Model = require('nanoid');

Model.define('User', {
  name: String
  surname: {type: String, default: "Rambo"}
})

Creating and saving a model

var user = Model.create('User', {name: "John", surname: "Rambo"});

user.save(function (err, saved_user) {
    // .. do some other stuff here
})

Finding a model

Finding by Id

var user_id = "123456";

var User = Model('User');
User.find(user_id, function (err, user) {
    // .. do something with the user
})

Find all or by criteria

var User = Model('User');
User.all(function (err, users) {
    // .. do something with the user
})

var User = Model('User');
User.where("name","Ben", function (err, users) {
    // .. do something with the users
})

Find first by criteria

var User = Model('User');
User.findFirst('name', 'Ben', function (err, user){
  // .. do something with the user
})

Custom View

var Band = Model.define("Band",{rank: Number, name: String});

Band.addView('ByRankAndName',{ 
  map: function (doc) {
    if (doc.model_type === 'Band') {
      emit([doc.rank, doc.name],1);
    }
  }
});

Band.view('ByRankAndName')
  .startkey([2, "Incubus"])
  .endkey([3, {}])
  .limit(10)
  .skip(3, function (err, bands) {
   // will only execute the chain when a function has a callback passed to it
});
