"“synchronous xmlhttprequest on the main thread is deprecated” using nodejs app.get or http-server" Code Answer


thanks for the comments. i have tracked down the issue, and it is within chrome - more particularly extensions.

the issue is with an extension i have: propertywizza v2.0. disabling this extension clears the problem. i will now uninstall it so it doesn't interfere with my development messages.

this was all deduced because i noticed that i had the same problem when accessing any website - including bbc and github for instance - from any computer in my home, as long as i used chrome.

my advice to anyone starting to debug front-ends for the first time is to check what errors you get on other websites in all your browsers before you begin. this will provide the "control" for your testing.
