Hitme

Easily handle multiple blocks of functions that should be run independent from eachother and calls a callback when everything is done.

Any errors thrown inside the functions given to the callback.

Example

var caller = hitme(function() { console.log('all done'); });

caller(function(cb) { console.log('a'); cb(null, 'a'); });
caller(function(cb) { console.log('b'); cb(null, 'b'); });

Expected result:

a
b
all done

Usage

var hitme = require('hitme');

hitme()

When calling hitme(), it will return a caller function for all your function blocks that should be run. hitme can take two arguments:

• callback - a function to call when everything is done
• thisArg - an optional argument to pass to the callback function as this value

The function returned by hitme(), takes only one parameter, a function. It will call this function as soon as the current block finishes execution (using setImmediate) and it should have one argument: a callback. This callback should be treated as a function with two parameters:

• error - if something is wrong and an erorr is passed, it will call the callback passed to hitme() with the error and any given data already passed by the other functions
• data - a value that will be passed as an additional parameter to the callback function sent to hitme().

hitme.serial()

Calling hitme.serial() has the exact same behavior and parameters of the plain hitme(), except that it won't start to execute the next function until the previous one has called its callback.

Hello World

var hitme = require('hitme');
var caller = hitme(function(err, data) { if (err) { console.log('ERROR'); console.log(err); return; } console.log(data + ' World'); });
caller(function(cb) { cb(null, 'Hello'); });
