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.

Contents

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);

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

Get TagList

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);

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'
});

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

save()

.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
dataManager.model('myModel').entry('f328af3')
.then(function(entry) {
  return entry.save()
})
.then(function(){
  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)
