model-golem

A model factory JS library to generate data mocks

Installing

npm install --save-dev model-golem

Using

Load the Factory:

// NodeJS / CommonJS Modules
var Factory = require('model-golem');

// ES2015 Modules
import Factory from 'model-golem';

Define a model:

var Person = {
  id: function() {

    // this.sequence is autoincremented on every creation step, starts from 0
    return this.sequence;
  },

  // Define the attributes giving their default values
  name: '',
  charisma: 42,

  // Reuse attributes
  username: function() {
    return this.item.name.toLowerCase().replace(/ /g, '');
  }
};

Instantiate the Factory with your model:

var peopleFactory = new Factory(Person);

Create your mocks!

var person = peopleFactory({
  name: 'Leo Balter',
});

/*
  person === {
    id: 0,
    name: 'Leo Balter',
    charisma: 42,
    username: 'leobalter'
  }
*/

Create your mocks from arrays!

var people = peopleFactory([
  {
    name: 'Green Avocados',

    // replace default values!
    charisma: 0
  },
  {
    name: 'Spicy Mustard',
    id: 100,
    charisma: 37,
    username: 'mryellow'
  }
]);

/*
  people === [
    {
      id: 2,
      name: 'Green Avocados',
      charisma: 0,
      username: 'greenavocados'
    },
    {
      id: 100,
      name: 'Spicy Mustard',
      charisma: 37,
      username: 'mryellow'
    }
  ]
*/

Get the stored data!

var stored = peopleFactory.store;

/*
  stored === [
    {
      id: 1,
      name: 'Leo Balter',
      charisma: 42,
      username: 'leobalter'
    },
    {
      id: 2,
      name: 'Green Avocados',
      charisma: 0,
      username: 'greenavocados'
    },
    {
      id: 100,
      name: 'Spicy Mustard',
      charisma: 37,
      username: 'mryellow'
    }
  ]
