This is a Sublime Text plugin that allows you to ctrl+click on a require path in a Node module to open that file.
To install, clone this repo in your Packages directory. Change the node_path setting in require-links.sublime-settings if you need to.
If the plugin is working, you should see the require paths in your JS files underlined. Control + click them to open the file referenced in the require path.
NOTE: The code for this plugin is shitty and using it is probably a bad idea.
