Methods

General Purpose

var sprintf = require('yow/sprintf');
var vsprintf = require('yow/vsprintf');
var once = require('yow/once');
var merge = require('yow/merge');

sprintf(args) - Just as you would expect. Uses the npm module 'sprintf-js'.
vsprintf(args) - Just as you would expect. Uses the npm module 'sprintf-js'.
once(fn, context) - Call a function just once and return the same result.
merge({}, objects...) - Like Object.assign() but does a deep merge.

File System

var mkdir = require('yow/mkdir')
var mkpath = require('yow/mkpath');
var fileExists = require('yow/fileExists');
var readJSON = require('yow/readJSON');
var writeJSON = require('yow/writeJSON');

mkdir(path) - Creates the directory you specify.
mkpath(path) - Creates the directory you specify. It will create multiple directories if they do not exit.
fileExists(path) - Nothing fancy, it just returns true/false.
readJSON(fileName) - Reads a JSON file and returns the contents.
writeJSON(fileName, object) - Writes an object to a JSON file.

Type Checks

var isArray = require('yow/isArray');
var isNumber = require('yow/isNumber');
var isString = require('yow/isString');
var isDate = require('yow/isDate');
var isFunction = require('yow/isFunction');
var isObject = require('yow/isObject');
var isInteger = require('yow/isInteger');
var isFloat = require('yow/isFloat');

isType(object, type) - Returns true/false if typeof equals 'type'.
isArray(object) - Is object an array?
isNumber(object) - Is object a JavaScript Number object?
isString(object) - Is object a String object?
isDate(object) - Is object a Date object (and contains a valid date)?
isFunction(object) - Is object a function object?
isObject(object) - Is object an object? BTW null is not an object.
isInteger(object) - Is object an integer?
isFloat(object) - Is object a float? Please note that isFloat(1.0) returns false.

random(min, max) - Returns a random number from min to max (inclusive).
random(array) - Returns a randomly chosen object in the specified array.

A light-weight http/https request module.

function example() {

	var Request = require('yow/request');
	var yahoo = new Request('https://query.yahooapis.com');

	function getQuote(ticker) {
		var query = {};

		query.q        = 'select * from yahoo.finance.quotes where symbol =  "' + ticker + '"';
		query.format   = 'json';
		query.env      = 'store://datatables.org/alltableswithkeys';
		query.callback = '';

		yahoo.get('/v1/public/yql', {query:query}).then(function(response) {
			var quotes = response.body.query.results.quote;

			if (typeof qoutes != 'Array')
				quotes = [quotes];

			console.log(ticker, '=', quotes[0].LastTradePriceOnly);

		})

		.catch (function(error) {
			console.log(error);

		});

	}

	getQuote('AAPL');
