Node.js Question

why babel stores .babel.json in USERPROFILE path

I'm running a nodejs app on azure web apps and i'm trying to integrate babel using npm in it. The problem is that babel is trying to acccess a file at


named .babel.json, a file that doesn't exist. This is most likely installed by:

npm install -g babel

On azure web apps, i can't seem to find it at all (even after running
npm install -g babel
in kudu for the site).

I copied the file in
myself to
using kudu but on web app restart the file disappears.

Is there a way to make babel work on web apps?


I did omit some things. The error appeared when i tried load

optional: ["es7.asyncFunctions"]

and the actual error i see in the streaming logs is

Application has thrown an uncaught exception and is terminated: Error:
ENOENT, no such file or directory 'D:\local\UserProfile.babel.json'
at Object.fs.openSync (fs.js:438:18)

I had this same problem, solved it by disabling the babel cache by setting the environment variable BABEL_DISABLE_CACHE=1 in my Application settings.
