  2 | A Node.js Simple Query Builder and ORM for AWS DynamoDB.
  3 | 
  4 | ## Motivation
  5 | When I visited [here ](http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/DynamoDB.html#query-property
  6 | ) for the first time, I closed it in a moment.
  7 | Because it is too long and hard to see to understand.
  8 | So I decided to make client to handle DynamoDB more easier and it doesn't take waste of time to read documentation for it.
  9 | 
 10 | ## Services that are used in Production
 11 | [<img src="https://raw.githubusercontent.com/noppoMan/npdynamodb/gh-pages/resources/chatcast_logo.png" width="250">](https://chatca.st)
 12 | 
 13 | 
 14 | ## Supported DynamoDB Api Versions
 15 | * 2012-08-10
 16 | 
 17 | ## Installation
 18 | ```sh
 19 | npm install npdynamodb
 20 | ```
 21 | 
 22 | ## Why is the Pure AWS-SDK in Node.js NOT good?
 23 | 
 24 | Parameters are like Chant of the magic.
 25 | [http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/DynamoDB.html](http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/DynamoDB.html)
 26 | 
 27 | ## Overview
 28 | Npdynamodb has modern interfaces to handle AWS DynamoDB.
 29 | We release you redundancy codes and see simple syntax.
 30 | Of course, will not see callback hell!
 31 | 
 32 | Npdynamodb has the following functions
 33 | * [Simple QueryBuilder](https://github.com/noppoMan/npdynamodb/blob/master/README.md#usage-of-querybuilder)
 34 | * [Light ORM(Active Record Model Like)](https://github.com/noppoMan/npdynamodb/blob/master/README.md#usage-of-orm)
 35 | * [DynamoDB Migrator](https://github.com/noppoMan/npdynamodb/blob/master/README.md#migration)
 36 | * [Command Line Interface](https://github.com/noppoMan/npdynamodb/blob/master/README.md#command-line-interfaces)
 37 | 
 38 | ### List of npdynamodb apis
 39 | * [QueryBuilder Apis](https://github.com/noppoMan/npdynamodb/blob/master/docs/query_builder_apis.md)
 40 | * [ORM Apis](https://github.com/noppoMan/npdynamodb/blob/master/docs/orm_apis.md)
 41 | * [Migration Apis](https://github.com/noppoMan/npdynamodb/blob/master/docs/migration_apis.md)
 42 | 
 43 | ## Usage of QueryBuilder
 44 | 
 45 | Initialization
 46 | ```js
 47 | var npdynamodb = require('npdynamodb');
 48 | var AWS = require('aws-sdk');
 49 | 
 50 | var dynamodb = new AWS.DynamoDB({
 51 |   apiVersion: '2012-08-10'
 52 | });
 53 | 
 54 | var npd = npdynamodb.createClient(dynamodb);
 55 | 
 56 | // Or can take options
 57 | var npd = npdynamodb.createClient(dynamodb, {
 58 |   timeout: 3000,
 59 |   initialize: function(){
 60 |     // Some Initialization here.
 61 |   }
 62 | });
 63 | ```
 64 | 
 65 | ##### Get by hash key (getItem operation)
 66 | ```js
 67 | npd().table('users')
 68 | .where("id", 1)
 69 | .first()
 70 | .then(function(data){
 71 | 
 72 |   console.log(data)
 73 |   // => {Item: {id: 1, name: 'Tonny'}, Count: 1, ScannedCount: 1}
 74 | 
 75 | })
 76 | .catch(function(err){
 77 |   console.err(err);
 78 | });
 79 | ```
 80 | 
 81 | ##### Get rows with where (query operation)
 82 | ```js
 83 | npd().table('users')
 84 | .where('name', 'tonny') //hash key
 85 | .then(function(data){
 86 | 
 87 |   console.log(data)
 88 |   // => {Items: [{id: 1, name: 'Tonny'}], Count: 1, ScannedCount: 1}
 89 | 
 90 | })
 91 | .catch(function(err){
 92 |   console.err(err);
 93 | });
 94 | ```
 95 | 
 96 | ##### Get multiple rows with where, filter and descending order
 97 | ```js
 98 | npd().table('chats')
 99 | .where('room_id', 'room1') // hash key
100 | .where('timestamp', '>', 1429454911) // range key
101 | .filter('user_name', 'tonny') // non index key
102 | .desc()
103 | .then(function(data){
104 |   console.log(data);
105 | })
106 | .catch(function(err){
107 |   console.err(err);
108 | });
109 | ```
110 | 
111 | ##### whereIn
112 | whereIn call batchGetItem instead of query operation.
113 | 
114 | ###### Single Key Usage
115 | ```js
116 | npd().table('chats')
117 | .whereIn('room_id', ['room1', 'room2', 'room3'])
118 | .then(function(data){
119 |   console.log(data);
120 | })
121 | .catch(function(err){
122 |   console.err(err);
123 | });
124 | ```
125 | 
126 | ###### Multiple Kyes Usage
127 | ```js
128 | npd().table('chats')
129 | .whereIn(['room_id', 'timestamp'], [['room1', 1429454911], ['room2', 1429454912], ['room3', 1429454913]])
130 | .then(function(data){
131 |   console.log(data);
132 | })
133 | .catch(function(err){
134 |   console.err(err);
135 | });
136 | ```
137 | 
138 | ##### Limit and offset
139 | ```js
140 | npd().table('chats')
141 | .where('room_id', 'room1')
142 | .limit(10)
143 | .offset(ExclusiveStartKey)
144 | .then(function(data){
145 |   console.log(data);
146 | })
147 | .catch(function(err){
148 |   console.err(err);
149 | });
150 | ```
151 | 
152 | ##### Count
153 | ```js
154 | npd().table('chats')
155 | .where('room_id', 'room1')
156 | .count()
157 | .then(function(data){
158 |   console.log(data.Count);
159 | })
160 | .catch(function(err){
161 |   console.err(err);
162 | });
163 | ```
164 | 
165 | ##### Extra options
166 | You can set extra options in callback of `feature` method. All options are transformed from property to method, But its name (camelized) and arguments are same as pure AWS-SDK for node.js.
167 | 
168 | ```js
169 | npd().table('users')
170 | .where('name', 'tonny')
171 | .feature(function(f){ // f is raw feature object.
172 |   f.consistentRead(true);
173 |   f.returnConsumedCapacity('TOTAL');
174 | })
175 | .then(function(data){
176 |   console.log(data);
177 | })
178 | .catch(function(err){
179 |   console.err(err);
180 | });
181 | ```
182 | 
183 | ##### create (Make Overwrite all of values, if key[s] have already existed.)
184 | ```js
185 | npd().table('users')
186 | .create({ // Also can save collection.
187 |   id: 2,
188 |   name: 'rhodes',
189 |   company: {
190 |     name: 'Stark Industry',
191 |     tel: '123456789',
192 |     zip: '123456789',
193 |     address: 'foo-bar-123'
194 |   }
195 | })
196 | .then(function(data){
197 |   console.log(data);
198 | })
199 | .catch(function(err){
200 |   console.err(err);
201 | });
202 | ```
203 | 
204 | ##### Update
205 | ```js
206 | npd().table('users')
207 | .set("company", "PUT", {
208 |   name: 'moved company',
209 |   tel: '123-456-789',
210 |   zip: '123-456-789',
211 |   address: 'foo-bar-456'
212 | })
213 | .set("suite_color", "ADD", 1)
214 | .update()
215 | .then(function(data){
216 |   console.log(data);
217 | })
218 | .catch(function(err){
219 |   console.err(err);
220 | });
221 | ```
222 | 
223 | 
224 | ##### Update with expressions
225 | ```js
226 | npd().table('users')
227 | .feature(function(f){
228 |   f.updateExpression('SET #gt = if_not_exists(#gt, :one)');
229 | 
230 |   f.expressionAttributeNames({
231 |     '#gt': 'gender_type'
232 |   });
233 | 
234 |   f.expressionAttributeValues({
235 |     ':one': 1
236 |   });
237 | 
238 |   f.returnValues('UPDATED_NEW');
239 | })
240 | .update()
241 | .then(function(data){
242 |   console.log(data);
243 | })
244 | .catch(function(err){
245 |   console.err(err);
246 | });
247 | 
248 | ```
249 | 
250 | ## Usage of ORM
251 | 
252 | Initialization
253 | ```js
254 | var npdynamodb = require('npdynamodb');
255 | var AWS = require('aws-sdk');
256 | 
257 | var npd = npdynamodb.createClient(new AWS.DynamoDB({
258 |   apiVersion: '2012-08-10'
259 | }));
260 | 
261 | var Chat = npdynamodb.define('chats', {
262 |   npdynamodb: npd,
263 | 
264 |   hashKey: 'id',
265 | 
266 |   rangeKey: 'timestamp'
267 | });
268 | ```
269 | 
270 | ##### Fast get with hash_key
271 | ```js
272 | Chat.find(1).then(function(chat){  // where('id', '=', 1)
273 |   // Get value of id key
274 |   console.log(chat.get('id'));
275 | 
276 |   // Get attribute keys
277 |   console.log(chat.keys());
278 | 
279 |   // Get attribute values
280 |   console.log(chat.values());
281 | 
282 |   // Pick specified key and value pairs
283 |   console.log(chat.pick('chat_id', 'timestamp'));
284 | 
285 |   // Transform as json string.
286 |   console.log(chat.toJson());
287 | });
288 | ```
289 | 
290 | ##### fetch with multiple conditions
291 | ```js
292 | Chat.where('id', 1)
293 | // complex conditions
294 | .query(function(qb){
295 |   qb.whereBeteen('timestamp', 1429212102, 1429212202);
296 | })
297 | .fetch()
298 | .then(function(data){
299 | 
300 |   // Check query result is empty?
301 |   console.log(data.isEmpty());
302 |   // => false
303 | 
304 |   // Get First Item
305 |   console.log(data.first().get('id'));
306 |   // => 1
307 | 
308 |   // Get Last Item
309 |   console.log(data.last().get('id'));
310 |   // => 1
311 | 
312 |   // Seequence(Also supported map, find, etc....)
313 |   data.each(function(item){
314 |     console.log(item.get('id'));
315 |   });
316 | 
317 |   // Pluck specific column values.
318 |   console.log(data.pluck('id'));
319 | 
320 |   // Get as object.
321 |   console.log(data.toArray());
322 |   // => [{id: 1, name: 'tonny', company: {....}}]
323 | 
324 | });
325 | ```
326 | 
327 | ##### Save
328 | ```js
329 | // As Static
330 | Chat.save({
331 |   room_id: 'room1',
332 |   ....
333 | })
334 | .then(function(chat){
335 |   console.log(chat.get('room_id'));
336 | });
337 | 
338 | // As Instance
339 | var chat = new Chat({
340 |   room_id: 'room1',
341 |   user_id: 1
342 | });
343 | chat.set('message', 'This is a message.');
344 | 
345 | chat.save()
346 | .then(function(chat){
347 |   console.log(chat.get('room_id'));
348 | });
349 | ```
350 | 
351 | ##### Destroy
352 | ```js
353 | chat.destroy()
354 | .then(function(data){
355 |   console.log(data);
356 | });
357 | ```
358 | 
359 | ##### Custom Methods and Properties
360 | ```js
361 | var Chat = npdynamodb.define('chats', {
362 |   npdynamodb: npd,
363 | 
364 |   hashKey: 'id',
365 | 
366 |   rangeKey: 'timestamp',
367 | 
368 |   customProtoTypeConstant: 1,
369 | 
370 |   customProtoTypeMethod: function(){
371 |     return this.get('id') === 1;
372 |   }
373 | 
374 | },
375 | 
376 | {
377 |   customStaticConstant: 1,
378 | 
379 |   customStaticMethod: function(){
380 |     return this.where('room_id', 'room1')
381 |       .query(function(qb){
382 |         qb.filter('timestamp', '>', 1429212102);
383 |       })
384 |       .fetch();
385 |   }
386 | });
387 | 
388 | // prototype
389 | Chat.find(1).then(function(chat){
390 |   console.log(chat.customProtoTypeConstant);
391 |   console.log(chat.customeProtoTypeMethod());
392 | });
393 | 
394 | 
395 | // static
396 | console.log(Chat.customStaticConstant);
397 | 
398 | Chat.customStaticMethod().then(function(data){
399 |   console.log(data);
400 | });
401 | ```
402 | 
403 | ## Migration
404 | We support schema migration for Dynamodb.
405 | 
406 | ##### First, initialize your project to run migration.
407 | ```sh
408 | npm install -g npdynamodb
409 | # cd /path/to/your/project
410 | npd init
411 | # created npdfile.js
412 | ```
413 | 
414 | ##### npdfile.js
415 | ```js
416 | 'use strict';
417 | 
418 | var AWS = require('aws-sdk');
419 | 
420 | var dynamodb = new AWS.DynamoDB({
421 |   apiVersion: '2012-08-10',
422 |   accessKeyId: "AWS_KEY",
423 |   secretAccessKey: "AWS_SECRET",
424 |   region: "ap-northeast-1"
425 | });
426 | 
427 | module.exports = {
428 | 
429 |   // Specify migration file path. Default is `./migrations`
430 |   // migration: {
431 |   //  migrationFilePath: './npdynamodb_migrations'
432 |   // },
433 | 
434 |   development: {
435 |     dynamoClient: dynamodb,
436 |     migrations: {
437 |       ProvisionedThroughput: [10, 10],
438 |       tableName: 'npd_migrations'
439 |     }
440 |   },
441 | 
442 |   staging: {
443 |     dynamoClient: dynamodb,
444 |     migrations: {
445 |       ProvisionedThroughput: [10, 10],
446 |       tableName: 'npd_migrations'
447 |     }
448 |   },
449 | 
450 |   production: {
451 |     dynamoClient: dynamodb,
452 |     migrations: {
453 |       ProvisionedThroughput: [10, 10],
454 |       tableName: 'npd_migrations'
455 |     }
456 |   }
457 | };
458 | ```
459 | 
460 | ##### Generate migration file.
461 | ```sh
462 | npd migrate:generate create_users
463 | # => /migrations/20150406083039_create_users.js
464 | ```
465 | 
466 | ##### Edit migration file
467 | ```js
468 | exports.up = function(migrator){
469 |   return migrator().createTable('chats', function(t){
470 |     t.string('room_id').hashKey();
471 |     t.number('timestamp').rangeKey();
472 |     t.provisionedThroughput(100, 100); // read, write
473 | 
474 |     t.globalSecondaryIndex('indexName1', function(t){
475 |       t.string('user_id').hashKey();
476 |       t.provisionedThroughput(100, 100); // read, write
477 |       t.projectionTypeAll(); //default is NONE
478 |     });
479 | 
480 |     t.localSecondaryIndex('indexName2', function(t){
481 |       t.string('room_id').hashKey();
482 |       t.number('user_id').rangeKey();
483 |       t.projectionTypeAll(); //default is NONE
484 |     });
485 |   });
486 | };
487 | 
488 | exports.down = function(migrator){
489 |   return migrator().deleteTable('chats');
490 | };
491 | ```
492 | 
493 | ##### UpdateTable Usage
494 | ```js
495 | exports.up = function(migrator, config){
496 |   return migrator().updateTable('test_table1', function(t){

553 | 
554 | ## QueryBuilder Callbacks
555 | You can be hooked several events and their can be taken promise.
556 | 
557 | Mechanism of Callbacks and Events
558 | ```
559 | operation called.
560 |       ↓
561 | callbacks: beforeQuery
562 |       ↓
563 | events: beforeQuery
564 |       ↓
565 | Sending Request to Dynamodb
566 |       ↓
567 | Getting Response from Dynamodb
568 |       ↓
569 | callbacks: afterQuery
570 |       ↓
571 | events: afterQuery
572 | ```
573 | 
574 | ```js
575 | // Register callbacks globally
576 | var npd = npdynamodb.createClient(dynamodb, {
577 |   initialize: function(){
578 |     this.callbacks('beforeQuery', function(){
579 |       if(this._fature.params['hash_key'] !== 1) {
580 |         return Promise.reject(new Error('invalid value'));
581 |       }
582 |     });
583 | 
584 |     this.callbacks('afterQuery', function(result){
585 |       return npd().table('related').create({
586 |         foo_id: result.Items[0]['hash_key'],
587 |         bar: 'string value'
588 |       });
589 |     });
590 |   }
591 | });
592 | 
593 | // Register callbacks at only this time.
594 | npd().table('foo').callbacks('beforeQuery', Func).create({
595 |   hoo: 'hoo',
596 |   bar: 'bar'
597 | });
598 | ```
599 | 
600 | ## Plugin and Extending
601 | Npdynamodb can be extended via plugins.
602 | 
603 | ```js
604 | npdynamodb.plugin(function(Klass){
605 | 
606 |   // Extend QueryBuilder
607 |   Klass.QueryBuilder.extend({
608 |     protoFn: function(){
609 |       console.log('foo');
610 |     }
611 |   },
612 |   {
613 |     staticFn: function(){
614 |       console.log('bar');
615 |     }
616 |   });
617 | 
618 |   // Extend Orm Collection
619 |   Klass.Collection.extend({
620 |     protoFn: function(){
621 |       console.log('foo');
622 |     }
623 |   },
624 |   {
625 |     staticFn: function(){
626 |       console.log('bar');
627 |     }
628 |   });
629 | 
630 |   // Extend Orm Model
631 |   Klass.Model.extend({
632 |     protoFn: function(){
633 |       console.log('foo');
634 |     }
635 |   },
636 |   {
637 |     staticFn: function(){
638 |       console.log('bar');
639 |     }
640 |   });
641 | 
642 | });
643 | ```
644 | 
645 | ### Available Plugins
646 | * [npdynamodb-typecast](https://github.com/noppoMan/npdynamodb-typecast) For casting hash and range key to actual attribution type
647 | 
648 | ## Browser Support
649 | Npdynamodb can be built using browserify or webpack, and pre-built or pre-built with uglified version can be found in the build directory.
650 | 
651 | ### For Browserify or Webpack
652 | ```js
653 | var AWS = require('aws-sdk');
654 | var npdynamodb = require('npdynamodb/build/npdynamodb');
655 | 
656 | var dynamodb = new AWS.DynamoDB({
657 |   apiVersion: '2012-08-10',
658 |   accessKeyId: "here is key",
659 |   secretAccessKey: "here is secret key",
660 |   region: "ap-northeast-1",
661 |   sslEnabled: true,
662 | });
663 | 
664 | var npd = npdynamodb.createClient(dynamodb);
665 | npd().table('table_name').where('id', 1).then(function(data){
666 |   console.log(data);
667 | });
668 | ```
669 | 
670 | ### For HTML
671 | ```html
672 | <script src="https://cdnjs.cloudflare.com/ajax/libs/aws-sdk/2.1.39/aws-sdk.min.js"></script>
673 | <script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/3.10.0/lodash.min.js"></script>
674 | <script src="https://cdnjs.cloudflare.com/ajax/libs/bluebird/2.9.33/bluebird.min.js"></script>
675 | <script src="../build/npdynamodb.min.js"></script>
676 | <script>
677 |   var dynamodb = new AWS.DynamoDB({
678 |     apiVersion: '2012-08-10',
679 |     accessKeyId: "here is key",
680 |     secretAccessKey: "here is secret key",
681 |     region: "ap-northeast-1",
682 |     sslEnabled: true,
683 |   });
684 | 
685 |   var npd = npdynamodb.createClient(dynamodb);
686 |   npd().table('table_name').where('id', 1).then(function(data){
687 |     console.log(data);
688 |   });
689 | </script>
690 | ```
691 | 
692 | ## Upgrading and Release Note
693 | #### Upgrading 0.1x -> 0.2x
694 | 
695 | ##### QueryBuilder
696 | There should be a minor change for QueryBuilder. 0.2x  QueryBuilder can take options as second argument of createClient.
697 | * 0.2.0: `timeout` option supported.
698 | * 0.2.6: `initialize` option and [callbacks](#querybuilder-callbacks) supported.
699 | * 0.2.7: [whereIn](wherein) method supported.
700 | 
701 | ##### ORM
702 | There should be a major change for ORM. 0.2x ORM constructor need to pass the npdynamodb instance instead of pure dynamodb instance.
703 | * 0.2.7: Supported to parse `whereIn` results.
