Dojo Toolkit style utilities and wrappers for Node.

This package is designed to provide Dojo-style AMD modules to make working with NodeJS more the "Dojo way".

Via cpm:

$ cpm install setten

Via volo:

$ volo add kitsonk/setten

The unit tests included with the package leverage the Dojo Objective Harness (D.O.H.). In order to leverage D.O.H. it is assumed that the dojo package and the util directory of Dojo which contains the doh package are installed as siblings of the setten package, for example:

lib/dojo
lib/setten
lib/util/doh

This can be changed by modifying the setten/tests/index.js package map.

The execute the tests, execute the following command from the /setten directory:

$ node tests

This is a wrapper for the NodeJS fs module, that takes the asynchronous callback calls and converts them into a dojo/promise Promise based return.

For example, you might have written code like this in "plain" NodeJS:

var fs = require("fs");

fs.readFile("/etc/passwd", function(err, data){
	if(err) throw err;
	console.log(data);
});

This could now be rewritten as:

require(["setten/dfs"], function(dfs){
	dfs.readFile("/etc/passwd").then(function(data){
		console.log(data);
	}, function(err){
		throw err;
	});
});

This is a wrapper for the fs-extra module. This takes the extra functions provides by this library and provides a dojo/promise based return.

This is a utility library used internally within the package. It provides a convenience function that converts callback functions into a dojo/promise Promise return. It would work like this:

require(["setten/util"], function(util){
	var fn = function(data, callback){
		// do something async
		callback(err, info);
	}

	var pfn = util.asDeferred(fn, this, false);

	pfn("something").then(function(info){
		// async return
	}, function(err){
		// handle error
	});
});

The arguments for asDeferred() are:

Because promises can only be fulfilled with a single value, if the callback is called with more than one argument (minus the error argument) then the promise is fulfilled with the supplied arguments as an array, otherwise it just fufills with the single argument it was passed.
