WebStorm using ES6 import with CommonJS module

I'm using WebStorm and want to use ES6 import instead of require. However when using import with libraries that use CommonJS like lodash I get a warning from WebStorm "cannot resolve symbol".

The code work perfectly as babel transform the import to require, I just want WebStorm to play along and not showing any error. I don't want to partly use ES6 import and partly require.

I'm using WebStorm version 2016.2.2.

Cannot resolve symbol castArray

Solution

  • webstorm can resolve es6 imports from CommonJS modules, but just in cases when modules are exported explicitly, like module.exports = module_name; or similar; but lodash modules are exposed in a tricky way:

    var freeExports = typeof exports == 'object' && exports && !exports.nodeType && exports; 
var freeModule = freeExports && typeof module == 'object' && module && !module.nodeType && module; 
var moduleExports = freeModule && freeModule.exports === freeExports; 
...
var _ = runInContext(); 
...
if (freeModule) { (freeModule.exports = _)._ = _; freeExports._ = _; }

    that's why WebStorm can't find modules there...
