I was running into issues with [[Exporting from Evernote#Yarle|Yarle]] due to various little bugs in my own code and theirs which wasn't reporting errors, just locking up or exiting silently.
So I dug up this incantation a couple of different times in order to figure out what was going on.
```sh
NODE_DEBUG=cluster,net,http,fs,tls,module,timers node app.js
```

To get Node and other things that run on it to dump all the internal debug info it can set the `NODE_DEBUG` environment variable before you run it.
