Data Manager JavaScript SDK

DEPRECATED¶

This Module is deprecated. There won't be any bugfixes or improvements. Use ec.sdk instead.

ec.datamanager.js¶

JavaScript SDK for ec.datamanager. By entrecode.

Simply use the generated APIs of the ec.datamanager with JavaScript. Supports usage in frontend (web) and backend (Node.js).

The SDK is fully promise-based. Since version 0.6.0 the SDK is fully HAL based and uses traverson, traverson-hal, and halfred.

Installation¶

With npm (for backend or frontend usage):

npm install ec.datamanager

With bower (for frontend usage in the Browser):

bower install ec.datamanager

The bower module only includes the minified build (and no tests etc.).

Usage¶

Loading the module in node.js:

var DataManager = require('ec.datamanager');

Loading the minified module in the Browser:

<script src="bower_components/ec.datamanager.js/build/datamanager.min.js"></script>

DataManager is then globally available.

(if you did not install using bower, the first part of the path may be different)

Initialization¶

You need to connect to your Data Manager API using the DataManager(options) constructor.

Initializing dataManager with existing token:

var dataManager = new DataManager({
  url: 'https://datamanager.entrecode.de/api/abcdef',
  accessToken: '8c3b7b55-531f-4a03-b584-09fdef59cb0c'
});

Initialization without token:

var dataManager = new DataManager({
  url: 'https://datamanager.entrecode.de/api/abcdef'
});

Alternative:

var dataManager = new DataManager({
  id: 'abcdef12'
});

Initialization with clientID for user management:

var dataManager = new DataManager({
  id: 'beefbeef',
  clientID: 'myAwesomeClient'
});

Initialization with errorHandler:

var dataManager = new DataManager({
  id: 'beefbeef',
  errorHandler: function(error){
    console.log(error);
  }
});

DataManager¶

Resolve¶

Retrieves information about the connected Data Manager. Like title, id, …

dataManager.resolve()
.then(function(dm) {
  console.log(dm.metadata.title);
  // Note: dataManager === dm
}, errorHandler);

Permission Check¶

To check if the currently instantiated Data Manager has a specific right you can use can(…).

dataManager.can('myModel:put:title')
.then(function(ok) {
  // the SDK is able to perform this action.
}, errorHandler);

dataManager.can('myModel:delete')
.then(okHandler)
.catch(function(err) {
  console.log(err.message); // permission_denied
});

Enable Cache¶

dataManager.enableCache('myModel', DataManager.DB_NODEJS)…
// OR
dataManager.enableCache({
  myModel: 3600,
  'my-model-with-dash': 600000
}, DataManager.DB_CORDOVA)
// OR
dataManager.enableCache([
  'myModel',
  'myOtherModel'
], DataManager.DB_BROWSER, 3600)
.then(function(models){
  console.log(models); // Array of LokiJS collections
  models[0].find({ lokiJS: 'doesThis' });
}, errorHandler);

If you use caching, you should not have the fields '$loki' and 'meta' in your Model.

Clear Cache¶

dataManager.clearCache('myModel')… // only myModel gets cleared
// OR
dataManager.clearCache([           // all in the array
  'myModel',
  'myOtherModel'
]…
// OR
dataManager.clearCache()            // all models
.then(function(){
  // cache is cleared and disabled
})
.catch(errorHandler)

Model¶

Model List¶

Retrieves all models of a Data Manager:

dataManager.modelList()
.then(function(modelList) {
  console.log(modelList) // object with models, titles are property names.
  console.log(modelList.myModel.metadata.titleField) // the title field of the model.
  modelList.myModel.entries()…
}, errorHandler);

Model Resolve¶

When creating a model directly it will not have the metadata ready. You can retrieve the metadata with resolve().

dataManager.model('myModel').resolve()
.then(function(model){
  console.log(model.metadata.titleField);
  model.entries()…
}, errorHandler);

Model enable cache¶

dataManager.model('myModel').enableCache(DataManager.DB_NODEJS, 3600)
.then(function(lokiJSCollection){
  lokiJSCollection.find({ lokiJS: 'doesThis' });
}, errorHandler);

Model clear cache¶

dataManager.model('myModel').clearCache()
.then(function() {
  // cache cleared and disabled
}, errorHandler);

Get JSON Schema¶

JSON schemas exist for models. To get one call getSchema().

dataManager.model('myModel').getSchema() // will load 'GET' schema
.then(function(myModelSchema) {
  console.log(myModelSchema)
}, errorHandler);

// For PUT or POST schema:
dataManager.model('myModel').getSchema('put'|'post')
.then(…);

Entries¶

Get EntryList¶

size: 0 will return ALL entries

dataManager.model('myModel').entryList({size: 100, sort: ['property', '-date']})
.then(function(res) {
  console.log(res.entries); // success! array of Entries
  console.log(res.count); // no. of received entries
  console.log(res.total); // total no. of available entries (accesss with pagination)
  if(res.hasOwnProperty('next'){
    res.next().then(…);
  }
  if(res.hasOwnProperty('prev'){
    res.prev().then(…);
  }
  if(res.hasOwnProperty('first'){
    res.first().then(…);
  }
}, errorHandler);

Get EntryList with cacheType¶

also works on entry(…) and entries(…)

dataManager.model('myModel').entryList({ cacheType: 'default' })
.then(function(list){
  console.log(list.entries); // refreshed data when cache was stale, cached data otherwise
}, errorHandler);
…
dataManager.model('myModel').entryList()
.then(function(list){
  console.log(list.entries); // same as cacheType: 'default'
}, errorHandler);
…
dataManager.model('myModel').entryList({ cacheType: 'refresh' })
.then(function(list){
  console.log(list.entries); // contains refreshed entries
}, errorHandler);
…
// the following type only works on entryList, is handled like default on entry/entries
dataManager.model('myModel').entryList({ cacheType: 'stale' })
.then(function(list){
  console.log(list.entries); // contains cache data, even stale
  list.refreshedData().then(function(list){
    console.log(list.entries); // contains refreshed data
  }, errorHandler);
}, errorHandler);

Get Entries¶

size: 0 will return ALL entries

dataManager.model('myModel').entries({size: 0, sort: ['property' , '-date']})
.then(function(entries) {
  console.log(entries); // success! array of Entries
  var clonedEntries = DataManager.cloneEntries(entries); // clones entry objects.
}, errorHandler);

Get Entry¶

dataManager.model('myModel').entry('my7fmeXh')
.then(function(entry) {
  console.log(entry); // success! an Entry
}, errorHandler);

// OR for nested entries

dataManager.model('myModel').entry('my7fmeXh', 2}) // since 0.6.0 no longer object
.then(function(entry) {
  console.log(entry); // success! an Entry
  var clonedEntry = entry.clone(); // clones entry object.
}, errorHandler);

Get nested Entry¶

Just like get entry but nested entries will be resolved as proper datamanager SDK objects.

dataManager.model('myModel').nestedEntry('my7fmeXh', 2}) // since 0.6.0 no longer object
.then(function(entry) {
  console.log(entry); // success! an Entry
  entry.value.nestedEntry.delete().then(console.log)); // this will work now.
}, errorHandler);

Create Entry¶

dataManager.model('myModel').createEntry({
  some: 'property',
  other: {
    proper: 'T\'s'
  }
})
.then(function(entry){
  console.log(entry.value._id); // the created entry
}, errorHanlder);

Delete Entry¶

The delete() function is an instance method of Entry. Just return entry.delete() in your entry promise handler:

dataManager.model('myModel').entry('f328af3')
.then(function(entry) {
  return entry.delete();
})
.then(function() {
  console.log('deleted'); // success!
})
.catch(errorHandler);

Update Entry¶

Works similar to delete():

dataManager.model('myModel').entry('f328af3')
.then(function(entry) {
  // first set the new values
  entry.value.key1 = 'new value for key1';
  entry.value.key2 = 2;
  // then save
  return entry.save();
})
.then(function(savedEntry){
  console.log(entry.value.key1); // prints 'new value for key1'
})
.catch(errorHandler);

Get Title of Entry¶

Returns the title of any nested entry in the entry.

Example:

dataManager.model('myModel).entry('f328af3', '2')
.then(function(entry) {
  console.log(entry.getTitle('child')); // prints the title of the child 'child'
  // is String for entry
  // is Array of String for entries
}, errorHandler);

Get Model Name of Entry¶

Returns the model title of any nested entry in the entry.

Example:

dataManager.model('myModel).entry('f328af3', '2')
.then(function(entry) {
  console.log(entry.getModelTitle('child')); // prints the model title of the child 'child'
}, errorHandler);

Users in the SDK¶

Register Anonymous User.¶

// register anonymous user.
dataManager.registerAnonymous()
.then(function(user) {
  // token was already added to dataManager instance.
  console.log(user.value.jwt); // token of the user. please save for later.
  console.log(user.value.accountID); // acocuntID of the user
  …
  dataManager.model('myModel')… // this will be using the logged in anonymous user.
  …
  user.logout()… // this will clear the accessToken and reset the sdk instance.
  user.isAnonymous(); // this will be true for anonymous users. false otherwise.
  user.isAnon(); // this will be true for anonymous users. false otherwise.
}, errorHandler);

The accessToken is a property of the DataManager instance:

dataManager.accessToken; // the currently used token for user authentication

Logout aka. clear accessToken and reset sdk.¶

…
// dataManager has a accessToken.
dataManager.logout();
// accessToken has been cleared and internal API connection was reset.
…

Email Available¶

You can check for email availability before you regiser a user:

dataManager.emailAvailable('some@mail.com').then(function(available){
  if(available){
    console.log('The email is available');
  } else {
    console.log('The email is NOT available');
  }
}, errorHandler);

Get Authorizaton Links¶

In order to receive prefilled urls for all other account management relations you can use getAuthLink().

dataManager.getAuthLink('anonymous', {clientID: 'myAwesomeClientID'})
.then(function(url){
  request.post(url).end(function(err, res){ // your own post request to register a anonymous user.
    …
    // token will not be set in datamanager. but can be manually:
    dataManager.accessToken = res.body.jwt;
  });

}, errorHandler);

This function provides you with all links found in the root API response with the relation <dataManagerShortID>:_auth/<linkName>. Most of them require clientID either set in the DataManager instance or directly as shown above. Others require additional properties (e.g. password-reset: requires clientID and email).

Applicable link names are:

anonymous
signup
login
password-reset
email-available
public-key.pem

Additional documentation for user management in Data Manager APIs can be found in the Data Manager documentation itself.

Get Account¶

Get information about the logged in account.

dataManager.account()
.then(function(account) {
  console.log(account.accountID);
}, errorHandler);

Asset File Helper¶

The SDK can help you getting asset files, and image assets in the right sizes. All file Helper can receive a locale property as last parameter if you want to request a specific locale (not the choosen one from Data Manager).

Note On Static Helper¶

The following functions are also provided as static functions in DataManager. E.g. you can call DataManager.getFileUrl(assetID).then(…); without connecting to a DataManager. This only works for assets in https://datamanager.entrecode.de DataManagers (not in Staging).

File Helper¶

dataManager.getFileUrl('46092f02-7441-4759-b6ff-8f3831d3da4b')
.then(function(url) {
  console.log(url)
), errorHandler);

Image Helper¶

dataManager.getImageUrl('46092f02-7441-4759-b6ff-8f3831d3da4b', 500)
.then(function(url) {
  console.log(url)
), errorHandler);

getImageURL expects a pixel value. The largest edge of the returned image will be at least this value pixels in size, if available.

Thumbnail Helper¶

dataManager.getImageThumbUrl('46092f02-7441-4759-b6ff-8f3831d3da4b', 100)
.then(function(url) {
    console.log(url)
), errorHandler);

The returned image will be a square-cropped variant with (in this example) at least 100 pixels (pixel value can be set as with getImageURL). Available sizes are 50, 100, 200 and 400 px. Other values will be mapped to next bigger one.

Assets¶

Get AssetList¶

dataManager.assetList()
.then(function(res) {
  console.log(res.assets); // array with assets
  console.log(res.count);
  console.log(res.total);
}, errorHandler);

Get Assets¶

dataManager.assets()
.then(function(assets) {
  console.log(assets); // array with assets
  var clonedAssets = DataManager.cloneAssets(assets); // clones assets objects.
}, errorHandler);

Get Asset¶

dataManager.asset('46092f02-7441-4759-b6ff-8f3831d3da4b')
.then(function(asset) {
  console.log(asset); // the Asset
  var clonedAsset = DataManager.cloneAsset(asset); // clones asset objects.
}, errorHandler);

Create Asset(s)¶

dataManager.createAsset(formData)
.then(function(assets){
  console.log(assets); // array with Get Asset Promises
  return assets[0]; // this is a Promise!
})
.then(function(asset){
  console.log(asset); // the created Asset.
})
.catch(errorHandler);

For node.js acceptable inputs are:

A path string to a local file (path/to/file)
An array of path strings (['path/to/file1', 'path/to/file2'])

For browsers acceptable inputs are:

FormData

Example:

```js $('form').submit(function (e) { e.preventDefault(); var data; data = new FormData(); data.append('file', $('#file')[0].files[0]);

var dataManager = new DataManager({ id: 'c024f209' }); dataManager.register(); dataManager.createAsset(data).then(function(assets){ return assets[0]; }).then(function(asset){ console.log(asset); // the created Asset. }) .catch(function(err){ console.log(err); });

e.preventDefault(); }); ```

Edit Asset¶

dataManager.asset('46092f02-7441-4759-b6ff-8f3831d3da4b')
.then(function(asset){
  asset.value.title = 'new title';
  return asset.save();
})
.then(function(savedAsset){
  console.log('success!'); // successfully saved asset
})
.catch(errorHandler);

Delete Asset¶

dataManager.asset('46092f02-7441-4759-b6ff-8f3831d3da4b')
.then(function(asset){
  return asset.delete();
})
.then(function(){
  console.log('success!'); // successfully deleted asset
})
.catch(errorHandler);

Asset File Helper¶

var url = asset.getFileUrl(); // original file

Asset Image Helper¶

var url = asset.getImageUrl(500) // size 500 image files

getImageUrl expects a pixel value. The largest edge of the returned image will be at least this value pixels in size, if available.

Asset Thumbnail Helper¶

var url = asset.getImageThumbUrl(100); // size 100 thumb files

The returned image will be a square-cropped variant with (in this example) at least 100 pixels (pixel value can be set as with getImageUrl). Available sizes are 50, 100, 200 and 400 px. Other values will be mapped to next bigger one.

Tags¶

dataManager.tagList()
.then(function(res){
  console.log(res.tags); // array of tags
  console.log(res.count);
  console.log(res.total);
}, errorHandler);

Get Tags¶

dataManager.tags()
.then(function(tags){
  console.log(tags); // array of tags
  var clonedTags = DataManager.cloneTags(tags); // clones tags objects.
}, errorHanlder);

Get Tag¶

dataManager.tag('tag1')
.then(function(tag){
  console.log(tag); // tag
  var clonedTag = DataManager.cloneTag(tag); // clones tag objects.
}).catch(function(error){
  console.log(error); // error getting tag
});

Edit Tag¶

dataManager.tag('tag1')
.then(function(tag){
  tag.value.tag = 'newTag';
  return tag.save();
})
.then(function(savedTag){
  console.log('success!'); // successfully saved tag
})
.catch(errorHandler);

Delete Tag¶

dataManager.tag('tag1')
.then(function(tag){
  return tag.delete();
})
.then(function(){
  console.log('success!'); // successfully deleted tag
})
.catch(errorHandler);

Documentation¶

class DataManager¶

Constructor¶

new DataManager(options) returns new DataManager Object

options contains following keys: url, accessToken,id, errorHandler and clientID. All are optional, but either url or id have to be set. Depending on the Data Manager Settings you will not be able to modify entries etc. when no accessToken is spcified.

Examples:

// initializing dataManager with existing token
var dataManager = new DataManager({
  url: 'https://datamanager.entrecode.de/api/abcdef',
  accessToken: '8c3b7b55-531f-4a03-b584-09fdef59cb0c'
});

// Initialization without token
var dataManager = new DataManager({
  url: 'https://datamanager.entrecode.de/api/abcdef'
  errorHandler: function(error) {
    handleError(error);
  }
});

// Alternative
var dataManager = new DataManager({
  id: 'abcdef',
  clientID: 'myAwesomeClientID'
});

DataManager Static Methods¶

`getFileURL(assetID, [locale])`¶

returns a file url. Optionally, a specific locale can be requested. The promise is getting rejected if no file is found.

`getImageURL(assetID, [size, locale])`¶

returns an image file. size is optional and states the size in pixels the largest edge should have at least.

Note that the image may still be smaller if the original image is smaller than size. If size is omitted, the largest size (i.e. the original image) is returned. Optionally, a specific locale can be requested. The promise is getting rejected if no file is found. The following sizes are being returned: 256, 512, 1024, 2048, 4096.

Example: The source image has a largest edge of 3000 pixels. getImageURL(id, 1000) will return the 1024px version. getImageURL(id, 4096) will return the original file with 3000 pixels.

`getImageThumbURL(assetID, size[, locale])`¶

returns an image thumbnail (square cropped). size is required and states the size in pixels the thumbnail square edge should have at least.

Note that the image may still be smaller if the original image is smaller than size. Optionally, a specific locale can be requested. The promise is getting rejected if no file is found. The following sizes are being returned: 50, 100, 200, 400

DB_NODEJS LokiJS env for node.
DB_CORDOVA LokiJS env for cordova.
DB_BROWSER LokiJS env for browsers.

Model object¶

Connecting a Model¶

var myModel = dataManager.model('myModel');

returns Model Object which is a promise.

Model Instance Methods¶

`enableCache([lokiJsEnv [, maxCacheAge])`¶

enables caching for the connected model with maxCacheAge (in ms). Returns a Promise which resolves to a LokiJS collection.

`clearCache()`¶

disables and cleares the cache for the model. return a Promise which resovles after successfully clearing cache.

`entries(options)`/`entryList(options)`¶

returns JSON Array of Entries (async). The request can be configured using options. Valid keys are:

size – number of entries to get (default: 10)
page – which page of entries to get when there are more than size (default: 1)
sort – sort by a different than the default property. Syntax: {direction}{property}[,…] where direction defaults to + (ascending order) and can be set to - (descending order) and property is the property to sort after. Can even be multiple properties (Array).
filter – for filtering after properties. Always an object with properties as key. The keys can have the following possible values:
- exact: exact filter. Value is the value to match exactly
- search: search filter. Value is the value to include
- from: Range filter: value is the value to have as lower end (≥)
- to: Range filter: value is the value to have as upper end (≤)
- any: Multiple-exact-match filter. Value is an Array containing allowed values (OR)
- all: Multiple-exact-match filter. Value is an Array containing required values (AND)
cacheType - selected cachedType (default: default)
- default - refreshes data when stale, cached otherwise
- refresh - refreshes data every time
- stale - resolves promise directly with stale data. add refreshedData (Promise) to result which can be used to refresh the data asyncronously. This only works on entryList.

Example:

// get entries
dataManager.model('myModel').entries({size: 100, sort: ['property' , '-date'])
.then(function(entries) {
   console.log(entries); // success!
})
.catch(function(error) {
   console.error(error); // error getting entries
});

entries() will return an array of entries. entryList() will return an object with the following structure:

{
  entries: [
    /* array of entries */
  ],
  total: 10,
  count: 5,
  next: /* Promise Factory */,
  prev: /* Promise Factory */,
  first: /* Promise Factory */
}

`entry(id [, levels])`¶

returns a Entry object as Promise. Levels property can be used to request nested entries.

`nestedEntry(id [, levels])`¶

returns a Entry object as Promise. Levels property can be used to request nested entries. Resolved nested elementes are proper SDK objects with all functions like save() and delete().

`createEntry(object)`¶

create a new entry. Returns the Entry.

`deleteEntry(id)`¶

return a Promise for deleting an entry.

`getSchema([method])`¶

retrieve JSON Schema. method is get by default. Other possible values: put, post.

`resolve()`¶

return a resolved model as Promise.

Can be used when creating a model object without calling modelList() to resolve model metadata.

Model Instance Properties¶

id The model id
title The model title. Same as id.
metadata Contains titleField and other model metadata.

Entry Object¶

Entry properties¶

values The properties of the Entry are available at entry.values.

Entry Instance Methods¶

.then(function(entry) {
  entry.values.key1 = 'new value for key1';
  entry.values.key2 = 2;
  return entry.save()
})
.then(function(savedEntry){
  console.log(entry.values.key1 = 'new value for key1';
});

delete()¶

deletes the entry. Promise.

Example:

// update entry

  console.log('deleted');
});

getTitle(String)¶

gets the title of any child entry identified by String. Will return String for single types and Array<String> for multiple types.

Example:

dataManager.model('myModel).entry('f328af3', 2')
.then(function(entry) {
  console.log(entry.getTitle('child')); // prints the title of the child 'child'
  // is String for entry
  // is Array of String for entries
}, errorHandler);

getModelTitle(String)¶

gets the model title of any child entry identified by String.

Example:

dataManager.model('myModel').entry('f328af3', 2')
.then(function(entry) {
  console.log(entry.getModelTitle('child')); // prints the model title of the child 'child'
}, errorHandler);

clone()¶

clones an entry.

Example:

dataManager.model('myModel').entry('f328af3', 2')
.then(function(entry) {
  var newEntry = entry.clone();

  assert(newEntry !== entry);
  assert(newEntry.value._id === entry.value._id);
  assert(newEntry.value.field1 === entry.value.field1);
  assert(newEntry.value.field2 === entry.value.field2);
  // …
}, errorHandler);

Asset object¶

Connecting an Asset¶

var myAsset = dataManager.asset('8c3b7b55-531f-4a03-b584-09fdef59cb0c');

returns Asset as a Promise.

Asset properties¶

value The properties of the Asset are available at asset.value.

Asset Instance Methods¶

save()¶

saves a changed Asset. Promise.

Example:

dataManager.asset('8c3b7b55-531f-4a03-b584-09fdef59cb0c')
.then(function(asset){
  asset.value.title = 'New Title';
  return asset.save();
})
.then(function(savedAsset){
  console.log(savedAsset.value.title; // prints 'New Title';
});

delete()¶

deletes the asset. Promise.

Example:

dataManager.asset('8c3b7b55-531f-4a03-b584-09fdef59cb0c')
.then(function(asset) {
  return asset.delete();
})
.then(function(){
  console.log('Deleted');
});

getFileUrl¶

syncronously returns a file url. Optionally, a specific locale can be requested.

getImageUrl¶

syncronously returns an image file. size is optional and states the size in pixels the largest edge should have at least.

Note that the image may still be smaller if the original image is smaller than size. If size is omitted, the largest size (i.e. the original image) is returned. Optionally, a specific locale can be requested. The following sizes are being returned: 256, 512, 1024, 2048, 4096.

Example: The source image has a largest edge of 3000 pixels. getImageURL(id, 1000) will return the 1024px version. getImageURL(id, 4096) will return the original file with 3000 pixels.

getImageThumbUrl¶

syncronously returns an image thumbnail (square cropped). size is required and states the size in pixels the thumbnail square edge should have at least.

Note that the image may still be smaller if the original image is smaller than size. Optionally, a specific locale can be requested. The following sizes are being returned: 50, 100, 200, 400

Tag Object¶

Connecting a Tag¶

var myTag = dataManager.tag('myTag');

returns Tag as a Promise.

Tag Properties¶

value The properties of the Tag are available at tag.value. Typically tag and count.

Tag Instance Methods¶

save()¶

saves a changed Tag. Promise

dataManager.tag('myTag')
.then(function(tag) {
  tag.value.tag = 'newTagName';
  return tag.save();
})
.then(function(savedTag) {
  console.log(savedTag.value.tag); // prints 'newTagName'
});

delete()¶

deletes the Tag. Promise.

Example:

dataManager.tag('myTag')
.then(function(tag) {
  return tag.delete();
})
.then(function(){
  console.log('Deleted');
});

Tests and Coverage¶

Before running tests, you need to npm install the dev dependency modules. For frontend tests phantomjs 2.0 has to be installed globally.

Running backend Tests with mocha (called with npm):

npm test

Alternative, using grunt:

grunt test           # tests backend and frontend
grunt test-backend   # only backend
grunt test-frontend  # only frontent

Running backend tests with coverage:

grunt coverage

Running frontend Tests with karma:

grunt test-frontend

The task will run a mocked server at port 54815. Make sure it is available.

Installing phantomjs 2.0 with homebrew

brew install phantomjs

Build¶

Should not be necessary. A new build for frontend usage (minified) can be triggered with

grunt build

(npm install is needed before for installing dev dependency modules)
