This is a high-level overview of MediaWiki development, including links to the key documents, resources and tools available to MediaWiki developers. It is written for skilled LAMP developers who have experience using MediaWiki.


MediaWiki is the software that powers Wikipedia, its sister projects and thousands of wikis all over the world.

MediaWiki is written in the PHP programming language[1]. It uses jQuery as the client JavaScript library.

MediaWiki is primarily written for the LAMP platform[2] and runs on most operating systems. MediaWiki primarily uses the MySQL and MariaDB database servers.[3]

Development happens in an open source style[4], is largely coordinated online, and supported by the Wikimedia Foundation, though volunteer community developers play a huge part as well.

Estensioni MediaWiki

MediaWiki È stata sviluppata per consentire modifiche senza cambiare il "nucleo del codice". In tal modo si facilita l'aggiornamento a una nuova versione di MediaWiki senza dover integrare manualmente parti del codice precedente. Ci sono sei punti principali di estensione che consentono agli sviluppatori di cambiare o ampliare quello che può fare MediaWiki. I punti di estensione sono:

  • API – access the data and metadata of MediaWiki instances through its web API.
  • Hooks - Aggiunge un simbolo x al markup wiki (ogni volta che compare x succede qualcosa)
  • Parser Functions - Crea un nuovo comando: {{#if|...|...|...}}
  • Skins - Cambia l'aspetto grafico di MediaWiki.
  • Special Pages - Aggiunge una pagina speciale.
  • Tag Extensions - Crea un nuovo tag: <newtag>...</newtag>
  • Extending wiki markup – add a parser hook to modify the content of wikitext.

Third-party wiki uses


  1. Not all of MediaWiki is written in PHP. Some supporting tools are written in other languages, including batch files, shell scripts, makefiles and Python.
  2. MediaWiki runs on most platforms that can support PHP, however, the lack of certain utilities or operating system features may limit the functionality or performance of MediaWiki on non-LAMP platforms.
  3. MediaWiki has support for DBMS other than MySQL and MariaDB, including Oracle, PostgreSQL, SQLite, and Microsoft SQL Server.
  4. Developers are a mix of volunteers and paid staff (or contractors) for various organizations. For a full list of who works on the MediaWiki code, read the DevelopersDevelopers article.
  5. Browse the source code and revisions of code repositories at or download the source code to your system by using Gerrit.
