Javascript – How to fix WebStorm warning “Unresolved function or method” for “require” (Firefox Add-on SDK)

firefox-addonfirefox-addon-sdkjavascriptwebstorm

I'm using WebStorm 7 for Firefox Add-on SDK development.

WebStorm shows a warning: "Unresolved function or method" for require().

I want to get rid of the warning.

var pageMod = require("sdk/page-mod");

NOTE:I already configured JavaScript-library (refer /lib/sdk globals).

Environment:

WebStorm 7.0.2
Windows 7 64bit
Firefox Add-on SDK 1.15beta1

Do you mean that require() is not resolved? You need to either add require.js to your project or enable Node.js Globals predefined library in Settings/Languages and Frameworks/JavaScript/Libraries.

(Edited settings path by @yurik)

In WebStorm 2016.x-2017.x: make sure that the Node.js Core library is enabled in Settings (Preferences) | Languages & Frameworks | Node.js and NPM

In IntelliJ 2018.3.2+ go to Settings (Preferences) | Languages & Frameworks | Node.js and NPM and enable Coding assistance for Node.js

Javascript – How to check for an empty/undefined/null string in JavaScript

If you just want to check whether there's a truthy value, you can do:

if (strValue) {
    //do something
}

If you need to check specifically for an empty string over null, I would think checking against "" is your best bet, using the === operator (so that you know that it is, in fact, a string you're comparing against).

if (strValue === "") {
    //...
}
