How to serve static files in Nodejs from proxy on OPDK from a file system directory?

[zubermohammad]

I am trying to server static files from Nodejs proxy. Since Nodejs support of "fs" module is limited to current working directory only I am not able to serve files from directories outside working directory.

One option could be to create a link of external directory say "/home/public-www/files" in current working directory. But the problem is every time we deploy proxy a new revision will be created and path to current working directory will change.

Is there a way to serve static files in apigee nodejs proxy?

Thanks!
