timer-jobs

Create timers that can run often, but not block by long executions. Great for worker-roles and such that have many jobs to do periodically.

Installation

	$ npm install timer-jobs

Usage

var TimerJob = require('timer-jobs');
 
var someTimer = new TimerJob({interval: 5000}, function(done) {
    console.log('hey');
    done();
});
someTimer.start();

TimerJob Class

constructor (options, callback)

Options:

• blocking: boolean - This determines if the timer should allow a new callback to be started before one finishes. Defaults to true.
• interval: Interval time, in milliseconds. Attempts to start the callback at this value.
• autoStart: boolean - No need to call timer.start() after creating the timer. Defaults to false.
• immediate: boolean - If true, calls the callback right when the job starts, doesn't wait for interval milliseconds. Defaults to false
• ignoreErrors: boolean - Ff true, automatically restarts the job if an error was sent from the callback.

Callback:

The function to call every interval milliseconds.

timer.start()

Starts up ye olde job!

timer.stop()

Stop the job! If a callback is in the middle of execution, it does not cancel it. Only when it calls back.

Event: start

function() {}

Emitted when the timer has successfully started.

Event: stop

function() {}

Emitted when the timer has successfully stopped.

Event: jobStart

function() {}

Emitted on every interval, BEFORE the callback function is called

Event: jobStop

function([err], [args]) {}

Emitted every time the callback calls its done function. If there is an error - the job HALTS until you start it back up, or if options.ignoreErrors is true.

• err: Error passed from the callback
• args: Any additional arguments passed from the callback
