R worker for Patavi using NodeJS. Inspired by OpenCPU, but taking an entirely different approach.

First, run npm install from the root directory. Then the following options are available:

• node worker runs the Patavi worker. You must define the PATAVI_BROKER_HOST environment variable as a RabbitMQ connection string that includes credentials.
• node worker-cli runs the worker without the dependency on Patavi. The worker will read input from standard in, show progress on standard out, and print the location of a temporary directory where results have been saved.
