New in nodeStorage v0.73.
I had to switch from Heroku to an AWS-hosted Ubuntu server that's hosting a bunch of other apps. Without the isolation that Heroku provides, the environment variables of all these apps were getting in each others' way. Rather than hack my way through all the arcane rules of environment variables, I decided to create a simpler more reliable (imho) way to configure River4 and nodeStorage, using a config.json file in the same directory as river4.js.
If you're using S3 storage, you need to provide the three values for your AWS account. Since the Amazon library is looking for these in environment variables, you must provide them that way.
Here's an example, the contents of config.json on my server (with values changed).
nodeStorage v0.77 adds two new elements to config.json.
