Vogels - DynamoDB data mapper for node.js

Check out vogels on github https://github.com/ryanfitz/vogels/


Features

• Simplified data modeling and mapping to DynamoDB types
• Advanced chainable apis for query and scan operations
• Data validation
• Autogenerating UUIDs
• Global Secondary Indexes
• Local Secondary Indexes
• Parallel Scans

You can configure vogels to automatically add createdAt and updatedAt timestamp attributes when saving and updating a model. updatedAt will only be set when updating a record and will not be set on initial creation of the model.

var Account = vogels.define('Account', {
  hashKey : 'email',

  // add the timestamp attributes (updatedAt, createdAt)
  timestamps : true,

  schema : {
    email : Joi.string().email(),
  }
});

If you want vogels to handle timestamps, but only want some of them, or want your timestamps to be called something else, you can override each attribute individually:

var Account = vogels.define('Account', {
  hashKey : 'email',

  // enable timestamps support
  timestamps : true,

  // I don't want createdAt
  createdAt: false,

  // I want updatedAt to actually be called updateTimestamp
  updatedAt: 'updateTimestamp'

  schema : {
    email : Joi.string().email(),
  }
});

You can override the table name the model will use.

var Event = vogels.define('Event', {
  hashkey : 'name',
  schema : {
    name : Joi.string(),
    total : Joi.number()
  },

  tableName: 'deviceEvents'
});

if you set the tableName to a function, vogels will use the result of the function as the active table to use. Useful for storing time series data.

var Event = vogels.define('Event', {
  hashkey : 'name',
  schema : {
    name : Joi.string(),
    total : Joi.number()
  },

  // store monthly event data
  tableName: function () {
    var d = new Date();
    return ['events', d.getFullYear(), d.getMonth() + 1].join('_');
  }
});
