MassEdit permits users to quickly edit or create an inputted set of pages. It can be used to affix templates to articles, add categories to pages, or simply create articles from prefabricated HTML.

As the author has experienced bugs while using the similar AutoEditPages script, MassEdit was created to serve as a slightly simpler, cleaner, more optimized version of AutoEditPages with additional i18n support.

Due to the potential for abuse in the form of vandalism or spam, the script can only be used by local staff (i.e. admins, bureaucrats, content-moderators, and rollbacks), FANDOM Staff, FANDOM Helpers, and VSTF.


Add the following to your personal common.js or global.js files or your wiki's MediaWiki:Common.js file:

    type: 'script',
    articles: [

If the script has been installed properly, a "MassEdit" option will appear on the Oasis toolbar and in the Monobook "toolbox" module.

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
  type: 'script',
  article: 'u:dev:FloatingToc/code.js'
importScriptPage('page1.js', 'wikiname');
importScriptPage('page2.js', 'wikiname');
    type: 'script',
    articles: [
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.
