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.

• 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.
