Parse server jobs scheduler

Purpose of the library

By default, _JobSchedule objects created on self-hosted Parse servers are not handled by the Parse server library. This library is a minimalist tool that fetches all _JobSchedule objects and schedules cron tasks that will run the scheduled jobs.

How to use it?

Install the library

$ npm install --save https://github.com/jaeggerr/parse-jobs-scheduler

Add those lines your Parse Cloud code main file

// Import the library
const JobsScheduler = require('parse-jobs-scheduler')

// Recreates all crons when the server is launched
JobsScheduler.recreateSchedule()

// Recreates schedule when a job schedule has changed
Parse.Cloud.afterSave('_JobSchedule', async (request) => {
  JobsScheduler.recreateSchedule(request.object)
})

// Destroy schedule for removed job
Parse.Cloud.afterDelete('_JobSchedule', async (request) => {
  JobsScheduler.destroySchedule(request.object)
})

I want to run this library on another server

It is easy to run the code on another server. Just initialize Parse with your master key before you call recreateSchedule(). The master key is required to fetch _JobSchedule objects.

Parse.serverURL = 'http://example.com:1337/parse'
Parse.initialize('myAppId', null, 'masterKey')

However, keep in mind that you can only manage one Parse server at once since the Parse object is a singleton.

Future improvements

• Add unit tests
• Add support for Parse Webhooks if you prefer to handle crons on another server
