Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (man) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

man

Node.js package. Provides a series of helper functions that allow you to perform asynchronous iteration and flow control.

Installation

npm install man

Callbacks aggregation

If you want to receive results of several callbacks at the same time, use callback() method:

var fs = require('fs'),
    man = require('man'),
    cb = man.callback();

fs.readFile('file1.txt', cb.callback);
fs.readFile('file2.txt', cb.callback);

cb.on(function (err, content) {
    // On each callback.
});

cb.done(function (result1, result2) {
    // When all callbacks have received the results.
});

Serial execution

var man = require('man');

man.do(function () {
    fs.readFile('file1.txt', this.next);
}).do(function (err, content) {
    fs.readFile('file2.txt', this.next);
}).do(function (err, content) {
    // ...
});

Parallel execution

var man = require('man');

man.doAsync(function () {
    // ...
    this.done(result1);
}).do(function () {
    // ...
    this.done(result2);
}).then(function (result1, result2) {
    // ...
});

Iterations

Serial iterations

var man = require('man');

man.for([1, 2, 3, 4, 5]).do(function (number) {
    // On each item.
    this.done(number + 1);
}).then(function (results) {
    // When all items have processed.
    console.log(results); // [2, 3, 4, 5, 6]
});

Parallel iterations

var man = require('man');

man.forAsync([1, 2, 3, 4, 5]).do(function (number) {
    // On each item.
    this.done(number + 1);
}).then(function (results) {
    // When all items have processed.
    console.log(results); // [2, 3, 4, 5, 6]
});
