The node executable itself should never write to disk, unless instructed to do so with the fs module, and I'm not aware of any operations that write to a temp directory either.
The npm installation is separate and definitely scatters files in quite a few places, although this can be restricted using npm settings. TiddlyServer may write to a temp directory if you upload files (it uses the formidable library) but then it moves the file to the correct directory using the rename command, so it would only be left there if the upload fails part way thorough. Other than that, TiddlyServer never writes to any directory not specified in settings.json (whether that's a tree path, backup directory, or log file). It does write to a file called uncaughtException.log if there is an uncaught exception, which is always in the installation directory. I am not aware that Node TiddlyWiki writes to anywhere outside of the data folder. But it would depend on which plugins are loaded. Each plugin has its own characteristics, but for the most part, it should not write anywhere outside the data folder. That should be true of all the stock plugins. Hope that helps.
