Hyperstore Documentation

About#

{: #about}

Hyperyun is a Backend-as-a-Service that features 'reactive' data queries: your application is notified whenever data you have asked about has changed so that you can update content immediately for your user. This documentation consists of the API specification as well as some tips and information for using Hyperstore quickly.

Quickstart#

{: #quickstart}

For each Hyperyun application your webpage needs to interact with, you must initialize a hyperstore connection:

Hyperstore.initialize('myAppName',['collectionA','collectionB','collectionC'])

This lets us access collectionA, collectionB, and collectionC in the 'myAppName' application's database by making calls to Hyperstore.myAppName. For convenience, the first application that is initialized is aliased to Hyperstore: this means (for the first app initialized) you can make calls like Hyperstore.find(...) and such when you would generally use Hyperstore.myAppName.find(...).

Once we're connected, we can perform whatever tasks we need to perform firstmost typically being a find of some kind:

var currentPizzas = []
var doNeatStuffWithHyperyun = function()
{
	//Look for all available cheese pizza types
	Hyperstore.myAppName.find({pizzaType: "cheese"}, function(res,err,ver){
		if(!err)
		{
			currentPizzas = res;
			console.log("There were " + res.length + " cheese pizzas available at " + ver);
		}
	})
}

We can also make changes to the database, such as inserting a new variety of pizza:

Hyperstore.myAppName.insert({pizzaType: "cheese", name: "The Medusa", toppings: ["gorgonzola", "feta"], base: "balsamic"});

By default whenever a new kind of pizza is added to the collection, our client will run any relevant find's callback parameter again: so, if our new 'gorngonzola' pizza is added, our original find will update self.currentPizzas to include the new pizza. You can disable this feature for any single find by setting reactive: false in the options for the find:

//Look for all available cheese pizza types, but ignore future updates
Hyperstore.myAppName.find({pizzaType: "cheese"}, {reactive: false}, function(res,err,ver){
		// etc...
});

More specific information about other Hyperstore usage can be found in the 'How to Use' section and the Hyperstore API

How to Use#

{: #howtouse}

Before using hyperyun.js on your client, you will have to register at Hyperyun and create a new application. After setting up your application at the Hyperstore Administration Panel, the server will be ready to interact with your client code.

Hyperstore provides a means by which to centrally store data concerning many users on the Hyperyun servers for easy retrieval and sharing across your userbase. Whenever a user of your client affects a change on the server, all other peers see the change without having to 'poll' the server: this behaviour is very useful in creating live web applications. Further, this is accomplished with a minimal of fuss in terms of code by using a consistent function callback strategy.

Hyperyun is built atop Mongo: each Hyperyun application is associated with its own set of Mongo collections, where all your 'documents' are stored. Hyperstore uses MongoDB syntax for data access queries, which is centered around sending JSON objects whose fields specify some constraint or new value for the documents to affect in the database. Familiarizing yourself with how to structure your application's data will be useful for ensuring you can get the most out of Hyperyun: consider researching NoSQL practices and perusing Mongo's documentation.

The most common methods you will therefore use are likely to be the Data Access methods such as Find, Insert, Update, and Remove which will let you interact with your database. You can find the specification and examples of these methods in the API.

Hyperyun Security

//TODO: Make this better There are two 'special' collections in each Hyperyun application: 'users' and 'files'. The 'users' table only allows writes to 'profile' document fields, and 'files' only allows writes to 'userdata' document fields. You will generally interact with these tables in a Read-Only fashion, or using the user account API and upload/removeFile methods. Any other collections' security settings are wholly yours to determine.

API#

Hyperyun##

To get access to Hyperyun, you will need to import hyperyun.js into your web application. Hyperstore comes bundled with lodash.js, and mixes in a few methods

Hyperstore.initialize(appName, collections [, options])###

{: #initialize}

The Hyperstore global object manages all your application connections to Hyperyun. To create a connection to your application's database, you use the initialize function on the global object. After the initialization has completed, the Hyperstore global object will have the application available as a member object (referenced by the appName) to make API calls on.

  • appName: The application identifier for the Hyperyun application you wish to connect to
  • collections: An array of collections to 'tune in' to in the application. By default, 'users' is connected to
  • options: Optional object that lets you target a different data server
    • server - domain to connect to instead of 'hyperyun.com'
    • fullserverurl - subdomain to connect to instead of '.hyperyun.com'

Example:

//Connect to the 'fooCollection' and 'barCollection' of an app named 'foo'
Hyperstore.initialize('foo',['fooCollection','barCollection'])
//Log in using the newly available 'foo' object in Hyperstore
Hyperstore.apps.foo.login(...)
//Run a command on 'fooCollection'
Hyperstore.apps.foo.fooCollection.find(...)
//Use the Hyperstore alias for the first-initialized app
Hyperstore.fooCollection.find(...) //Same as Hyperstore.foo.fooCollection.find(...) in this case

Data Access##

Hyperyun is powered by MongoDB, a NoSQL implementation. As such, it uses Mongo query syntax for the various data access methods here: you can find full documentation about how to construct such JSON objects at the MongoDB Official Documentation page.

find (selector, [options , callback])###

{: #find}

This method retrieves documents from Hyperyun according to your query selector, and will attempt to cache the results locally for efficient retrieval later. This method returns a UUID string that can be used in conjunction with closeFind to disable the find (if reactive) later in your code's execution.

  • selector: MongoDB query object responsible for selecting relevant documents.
  • options: object containing any of the following parameters
    • reactive - set to false to not trigger this query's callback whenever the find's results change. Default: TRUE
    • projection - MongoDB projection object for filtering document fields. _id is always returned, however.
    • sort - MongoDB sort object for ordering documents returned
    • skip - Number of documents to skip before including documents in the find's results
    • limit - Maximum number of documents for this find to return
  • callback: Optional function callback to perform upon successful find (and whenever the find's results change, if this find is reactive). This callback is passed the following parameters in the order (res, err, ver).
    • res - An array of JSON objects returned by the query (or null if an error occurred)
    • err - Error message (or false if no error occurred)
    • ver - Timestamp of the update operation on the server

Example:

//Find users named 'Ted'
Hyperstore.myApp.myCollection.find({name: "Ted"},function(res, err, ver){
	if(!err)
	{
		for(var entry in res)
			console.log(JSON.stringify(entry));
	} else throw err;
});

.

//Show the first 20 documents in the collection
Hyperstore.myApp.myCollection.find({},{limit:20},function(res, err, ver){
	if(!err)
	{
		for(var entry in res)
			console.log(JSON.stringify(entry));
	}
	else throw err;
});

.

//Display only the toppings (not other information) for each kind of 'cheese' pizza
Hyperstore.myApp.myCollection.find({pizzaType: "cheese"},{projection:{toppings:1}}, function(res, err, ver){
	if(!err)
	{
		for(var entry in res)
			console.log(JSON.stringify(entry.toppings));
	} else throw err;
});

.

//Search for women's names in the database, but don't react when women are added/removed from the collection
Hyperstore.myApp.myCollection.find({gender: "female"}, {reactive:1, projection:{name:1}}, function(res, err, ver){
	if(!err)
		femaleNameArray = res;
	} else throw err;
});

findOne (selector, [options , callback])###

{: #findone}

This is a convenience method for find, where the limit: options parameter is set to 1.

    • sort - MongoDB sort object for ordering documents returned
    • skip - Number of documents to skip before including documents in the find's results
  • callback: Optional function callback to perform upon completion (and whenever the find's results change, if this find is reactive). This callback is passed the following parameters in the order (res, err, ver).
    • res - The JSON object returned by the query (or null if an error occurred)
    • err - Error message (or false if no error occurred)
    • ver - Timestamp of the find operation on the server

Example:

		console.log(res);
	} else throw err;
})

closeFind (find_uuid, [callback])###

{: #closeFind}

  • find_uuid: UUID string of the reactive find to be disabled.
  • callback: Optional function callback to perform after the find has been disabled. Note that this method is synchronous, so the callback will simpy run when the function has finished execution. This callback is passed false if the find was not found, or the object that was removed from the findlist if successfully destroyed.

forceFind (find_uuid)###

{: #forceFind}

This method forces a refresh of a currently-active reactive find with the remote server, refreshing the cache.
