• In /server/server.js, import your job in the "Jobs" section
• In /server/server.js, add new cron jobs to run to worker on server start in "Add Jobs to Worker" section:

Worker.addJob([INSERT_NAME_OF_YOUR_JOB])

• Add Job

Worker.addJob([INSERT_NAME_OF_YOUR_JOB])

• Remove Job

Worker.removeJob([INSERT_NAME_OF_YOUR_JOB])

• Run Specific Job

Worker.runJob([INSERT_NAME_OF_YOUR_JOB])

• Run All Jobs (Server is set to run all jobs added to worker on start)

Worker.runAllJobs()

• Print list of all jobs the worker is queued to run

Worker.printAllJobs()
