Loading the editor takes time. Why wait, if you only want to read a page's source code? This little tool adds a "View source" link to the "Edit" dropdown menu that replaces the page's content with the raw code. Pick "View article" from the same menu to return the page to normal.

Installation

See also: Help:JavaScript and CSS Cheatsheet

To install View Source, simply add the appropriate row to your importArticles() call in your global.js or your wiki's MediaWiki:Wikia.js - depending on whether you want to use this addon as a personal script or a site script.

Installation

Add this JavaScript on your wiki:

Global Personal Site-wide
w:Special:Mypage/global.js Special:Mypage/common.js MediaWiki:Common.js
importArticles({
    type: 'script',
    articles: [
         'u:dev:MediaWiki:View_Source/code.js'
    ]
});
importArticles — Best Practices for installing JavaScript on Fandom
The importArticles statement is designed to combine multiple HTTP requests into a single data transfer, allowing multiple scripts to load and execute faster. If you've been installing several different scripts, your JavaScript file has probably accumulated unnecessary import statements. Click "Expand" to learn how to efficiently batch import scripts to speed up performance and make your code look cleaner. One other approach is by using the MediaWiki:ImportJS.
If your JavaScript file has several lines of code that say importScript, importScriptPage, or importArticles, you may be able to combine them! By batch importing a collection of scripts with a single import, your JavaScript code will load faster and look cleaner. Consider the example below. On the left is an example of what your JavaScript file might currently look like. On the right is how you could improve that code.
Multiple imports — messy and slow One import — clean and efficient
importScriptPage('AjaxRC/code.js','dev');
 
importScript('MediaWiki:localScript.js');
 
importArticle({
  type: 'script',
  article: 'u:dev:FloatingToc/code.js'
});
 
importScriptPage('page1.js', 'wikiname');
 
importScriptPage('page2.js', 'wikiname');
importArticles({
    type: 'script',
    articles: [
        'u:dev:AjaxRC/code.js',
        'MediaWiki:localScript.js',
        'u:dev:FloatingToc/code.js',
        'u:wikiname:page1.js',
        'u:wikiname:page2.js'
    ]
});
Note: In this example, pay close attention to the placement of commas and other punctuation. For people who aren't familiar with programming (and even those who are!), a common mistake when writing code is to accidentally delete, forget, or misplace critical symbols like commas or quotation marks. This can cause a syntax error that breaks the code. Carefully follow the convention shown here when using importArticles.
But there's much more to importArticles than just this! For more examples and advanced usage, see the help page at Help:Including additional JavaScript and CSS.
