•  Intellij will automatically redirect you to the source URL of nodejs modules. Check all details and check "Associate with project" and click again the "Configure" button.
   
  
   
  Note: If you uncheck the "Associate with project" option then the node source code is configured in intellij but not added to your current project. If you want to add it manually then see the last step.
  
  
   
  Downloading take few minute to download all modules. Once it finish you will see that "Core modules is set up".
