Using Heroku Scheduler with Node.js

Question

There is literally no tutorial about using Heroku Scheduler with Node.js. Assume that I have a function called sayHello() and I would like to run it every 10 mins. Ho

Answer 1

Christophe's answer worked for me until I needed to pass a parameter to the script, at which point it failed. The issue is that node should not be specified in the task. Here is how exactly to get it working:

1. In your Procfile, define a process type for your script. See below for a typical Procfile with a web process and, for running "scheduled_job.js", a second process type imaginatively named "worker".

   web: node app.js
   worker: node scheduled_job.js
   

2. In the Heroku scheduler's Task column, just enter the name of the process type ("worker" in this example) with or without parameters. Don't enter 'node' before it. Heroku shows a dollar sign in front of it, so examples of a valid setup would be $ worker (run without arguments) or $ worker 123 abc (to execute scheduled_job.js with arguments "123" and "abc")
