What steps do I need to take to show WebStorm that my userscript is successfully loading jQuery?

My situation involves a userscript that utilizes the @require directive in the metadata block to load jQuery from an external source:

// @require      https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js

It seems like WebStorm isn't aware of userscripts, which causes it to not recognize that variables such as $ will be defined by the time they are used in my code.

Is there a way to make WebStorm treat my file as if it has directly included the contents of jquery.min.js at the beginning, so that I stop receiving warnings about undefined variables like $? For example, could I place a local copy of jquery.min.js in a designated folder and instruct WebStorm to consider all declarations from that file?

Answer №1

A big thank you to hobbs for the valuable comment - I found JetBrains' documentation on Configuring JavaScript Libraries.

This is what worked for me:

  1. I downloaded jQuery 2.1.3 (as opposed to the default version of 2.0.0 provided by JetBrains).
  2. In WebStorm, I navigated to Settings > Languages & Frameworks > JavaScript > Libraries.
  3. Clicked on Add and followed these steps:
    1. Gave it a name.
    2. Added the jquery-2.1.3.js file using the green plus button.
    3. Set Type to Debug.

With these changes, my userscript now successfully loads jQuery in WebStorm. Success!
