Nirvana

Nirvana is the name of Fandom's application framework. In the most basic sense, it consists of controllers and templates these controllers are rendering. Some controllers and their public methods can be accessed through /wikia.php or /api/v1 on every Fandom wiki, as well as using the $.nirvana object

Endpoints

/wikia.php

Script for accessing methods of any class extending WikiaController that allows external requests. Accepts two arguments as query string parameters:

• controller — Controller to access. If the class name of the controller is SomethingController, this field accepts both Something and SomethingController in order to access it.
• method — Public method to access. Defaults to index. Case-insensitive due to PHP method name case-insensitivity.
• format — Can be set to json or html. Default is html, but methods with no templates associated just return data as JSON.

For example, /wikia.php?controller=UserProfilePage&method=renderUserIdentityBox&title=User:KockaAdmiralac&format=json calls the renderUserIdentityBox method of the UserProfilePageController class and requests that the data is returned as JSON.

/api/v1

Can access only a subset of externally accessible controllers. Accessible controllers are those whose names end with ApiController with public method names starting with get. Always returns data as JSON. For example, /api/v1/Users/Details?ids=KockaAdmiralac accesses the getDetails method of the UserApiController class.

Controllers accessible through /api/v1 often have their parameters and responses documented on the same page. Some controllers, such as the WikisApiController are only accessible from Community Central.

JavaScript

There is a helper object for accessing Nirvana's endpoints from client-side scripts defined in wikia.nirvana AMD module: $.nirvana.

Methods

$.nirvana.sendRequest(attr)

Used for sending requests to /wikia.php, given the controller, method name and data.

attr is an object consisting of the following:

• controller — Controller name. Required parameter.
• method — Method name. Required parameter.
• format — Format of the response. Can be set to json (default), html or jsonp.
• type — Can be set to GET or POST (default).
• data — Object with parameters to pass to the controller. If set to a string, converts it to the format of the response.
• callback — Function called after the request succeeds.
• onErrorCallback — Function called after the request fails.
• contentType — Passed as a contentType parameter in an $.ajax() call.
• processData — Passed as a processData parameter in an $.ajax() call.
• scriptPath — Used instead of the wgScriptPath variable.

$nirvana.getUrl(options)

Used for obtaining a /wikia.php URL.

options is an object consisting of the following:

• controller — Controller name. Required parameter.
• method — Method name. Required parameter.
• format — Format of the response. Can be set to json (default), html or jsonp.
• scriptPath — Used instead of the wgScriptPath variable.
• data — Object with parameters to pass to the controller. If set to a string, converts it to the format of the response.

$nirvana.getJson(controller, method, data, callback, onErrorCallback)

Shorthand for sending a GET request to Nirvana.

Parameters are as described in the sendRequest method. method parameter may be omitted.

$nirvana.postJson(controller, method, data, callback, onErrorCallback)

Shorthand for sending a POST request to Nirvana.

Parameters are as described in the sendRequest method. method parameter may be omitted.

Available controllers

There are many Nirvana controllers available, but only a few of them are properly documented. The easiest way to find them is to use the file search option in Fandom's MediaWiki code repository and search for Controller.class.php. If you are unsure about how a controller can be used, feel free to leave a message on Fandom Developers Wiki's API Discussion board, and other users who worked with Nirvana controllers in past may be able to help you.

Definitions

These classes are used within the Nirvana framework.

WikiaApp

Wrapper for many common operations, such as hooks registration and getting access to global variables.

WikiaController

Wraps queries and data related logic into functions for the front end.

Can be accessed through /wikia.php or /api/v1 endpoints.

WikiaException

The exception class typically thrown by Nirvana controllers.

WikiaModel

Abstract class for other helper classes with methods for database access.

WikiaObject

Abstract class extended by non-controllers that still need framework variables.

WikiaRequest

An incomplete replacement for MediaWiki's WebRequest class.

WikiaResponse
