deepjs

#deepjs

deepjs is a set of tools for managing standard javascript functions, objects, persistent collections and promises.

Based on Layered and Chained Programmation approach, it provides, uses and mixes :

• Layered Aspect Oriented Programmation
• Query Based Programmation including Code Sheet
• Object Capabilities Management (or Model)
• Full promised and chained asynch management
• Homogeneous HTTP/Rest ressources management
• Modularisation by Protocol approach

It works both server side and browser side. Its aim is to be totaly unobstrusive, ergonomic as possible and usable with any other js lib/framework. It wants also to be absolutly homogeneous between server and browser sides.

As jquery (that is highly unobstrusive and ergonomic) works on standard DOM objects, deepjs works on standard js objects and functions structures.

See tutorials page for details.

Despite of documentations state and too few tescases, deep has now achieved a certain kind of maturity and stability. It is born through years of work and ideas, and has been named differently through its long history...

Real huge thanks to Kris Zyp and all his incredible work on promises, json-schema, compositions, RQL, OCM, Persvr, etc. Thanks also a lot to his bunch of articles on Thin-Server, No-SQL, mVC, etc. and all those realy smart architecural considerations that lead us trough our research...

We are now polishing last little things and working hard on documentation and testcases to provide, as quick as possible, an astonishing, totaly new and almost battle ready web 3.0 plateform that we know you will realy enjoy.

deepjs : simply made with love.

Nodejs simple example

var http = require('http');
var deep = require('deepjs');

deep.store.Collection.create("myobjects", []);

var titles = ["hello", "deepjs", "world"];
var count = 0;

http.createServer(function (req, response) {
	deep
	.store("myobjects")
	.post({ title:titles[++count%3], count:count })
	.get(String(req.url).substring(1))
	.done(function(res){
		response.writeHead(200, {'Content-Type': 'application/json'});
		response.end(JSON.stringify(res));
	})
	.fail(function(error){
		console.log("error : ", error.toString());
		response.writeHead(error.status || 500, {'Content-Type': 'application/json'});
		response.end(JSON.stringify(error));
	});
})
.listen(1337, '127.0.0.1');

console.log('Server running at http://127.0.0.1:1337/');

Then, open your browser, go to http://127.0.0.1:1337/, refresh few times, and try :

http://127.0.0.1:1337/_an_id_of_an_item_in_collection_ or http://127.0.0.1:1337/?title=deepjs or http://127.0.0.1:1337/?count=lt=2

Layered Aspect Oriented and Query Based programmation

	//-----------------Models
	var land = {
		location : "pls override this value with your own location",
		watering : function () {
			console.log("Water is applied on all the land");
		}
	};
	//-----------------Aspects
	var orchard = {
		plants : [{uri:"appletree",growSpeed:10}],
		watering : deep.compose.after(function () {
			console.log("We put some mulch after watering");
		})
	};

	var kitchenGarden = {
		plants : [{uri:"carrots",growSpeed:6}],
		watering : deep.compose.before(function () {
			console.log("We protect seedlings before watering");
		})
	};
	//-----------------Implement

	var myOwnLand = {
		location : "Sao Francisco do Guaporé",
		plants : [{uri:"grass",growSpeed:2}]
	};

	deep(myOwnLand)
	.bottom(land)
	.up(orchard,kitchenGarden)
	//Query based object modelisation
	.query("/plants/*").up({
		size : 0,
		grow : function () {
			this.size += this.growSpeed;
		},
		prune : function (heightpruned) {
			this.size -= heightpruned;
		}
	});


	console.log("myOwnLand is : ", myOwnLand);
	myOwnLand.watering();

	//Query based object manipulation
	deep(myOwnLand)
	.query("/plants/*")
	.run("grow")
	.query("/plants/*?size=gt=5")
	.run("prune",[2]);

	console.log("myOwnLand is : ", myOwnLand);
