Port configuration Memes

Oh look, it's the "my code works perfectly on my machine" starter pack! Someone clearly swapped the values for host and port here. Port should be a number (like 8001) and host should be a string (like 'localhost'). This is the kind of bug that silently lurks in your codebase until 3 months later when your boss demos the app to investors and everything crashes spectacularly. Then you spend 4 hours debugging only to find this gem and question your entire career choice.
