Easy to use, minimalistic wrapper for AWS DynamoDB

$ npm install @awkward/simple-dyno

Please also include require('babel-polyfill') in your project for node <= 4.0

• Easy way to create a model, keeping your code consistent and saving it to DynamoDB
• Serializers to format your (json) response
• Validation based on Joi
• Encryption using bcrypt for your passwords
• Local DynamoDB for testing purposes

To create a new entry, and options can include {skipValidation: true}:

Model.create(attributes, options)

To get an entry or multiple entries:

Model.get(keyValues)

To update an entry, and options can include {skipValidation: true}:

Model.update(keyValues, attributes, options)

To delete an entry:

Model.destroy(keyValues)

To perform a scan operation (not recommended):

Model.find(attributes)

To query using a secondary index:

Model.query(indexName, attributes)

To serialize the response attributes:

Model.serialize(response, options)

To run a local DynamoDB (which runs on Java), by default runs in memory but you can also store on disk using {inMemory: false} as options:

SimpleDyno.local(options)

To set the config, which you can pass the following options {accessKeyId: '', secretAccessKey: '', region: ''}:

SimpleDyno.config(options)

// Import deps
import { Model } from 'simple-dyno';
import Joi from 'joi';

// Add your own methods
class UserModel extends Model {
  myAwesomeMethod(obj) {
    return obj.firstName+obj.lastName;
  }
}

// Create model instance
var User = new UserModel({
  table: 'users',
  hashKey: 'email',
  serializers: {
    default: ['email'],
    scary: ['access_token', 'password']
  },
  schema: {
    email: Joi.string().email(),
    access_token: Joi.string(),
    password: {
      format: Joi.string().regex(/[a-zA-Z0-9]{3,30}/),
      encrypt: true
    }
  }
});

var userObj = yield User.create({email: '[email protected]', access_token: 'aW12k3KDASsd012Ms1Mf29Mc7', password: '******'})
return User.serialize(userObj, {format: 'scary'});

// Import deps
import * as SimpleDyno from 'simple-dyno';

// Start a local DynamoDB
yield SimpleDyno.local();

// Create accociated tables for the following model(s)
SimpleDyno.load(User);

• Fix CI by allowing Java to run on Travis
• Migrations
• Better docs (explain how AWS works)

Please create a pull request, make sure to include and update the tests and that they're working. And don't forget to build the minified version (with babel) with npm run build.

Use npm test to do a test run using Mocha.
