Task Scheduler

Work in progress

Task Scheduler Server to schedule or run scripts/applications/commands which:

• scales. Server consists of a master task queue process and the workers.
• has web interface
• has RESTful API
• has websockets
• has database persistence
• has forever-monitor integration

Time Triggers

Describe with:

• RRule
• Cron
• One time triggers:
  • Date instance
  • relative to the current time, like in 2 hours and 20 minutes

Executors

• source: { src: 'tasks/foo.js' }
• command: { command: 'wget -i file' }
• request: { url: 'http://foo.com/baz', method: 'POST', data: {}}

CLI

$ npm i -g task-scheduler
$ tasksched --help

# Server
$ tasksched server --help
# - start the server
$ tasksched server start
# - stop the server
$ tasksched server stop

# Application
$ tasksched app --help
# - create the application. Tasks are bound to the app after the authorization
$ tasksched app create --name Foo --password BazPass
# ... for more infos, see the help action

# Task
$ tasksched task --help
# - create the task
$ tasksched task create --name FooName --trigger "in 20 minutes" --exec.src baz.js
# ... for more infos, see the help action

Web Interface

Start the server $ tasksched server start and navigate to http://localhost:5888/

Client module

	var client = require('task-scheduler-client');
	client
		.ensureTask({
			name: 'sync data',
			trigger: 'FREQ=DAILY;BYHOUR=23',
			exec: {
				src: '/tasks/sync-data.js'
			}
		})
		.done(onSuccess) //> created
		.fail(onError)   //> task creation failed
		;

If the task with the same name, same trigger and exec already exists, it will do nothing.
