Meteoro de pegasuus! Desenvolvendo aplicações realtime com MeteorJS

METEOR DE PEGASUSDESENVOLVENDO APLICAÇÕES WEB COM METEOR.JS

Meteor is developed by the Meteor Development Group. Thestartup was incubated by Y Combinator and received

$11.2MM in funding from Andreessen Horowitz in July 2012.

HISTORY

https://en.wikipedia.org/wiki/Meteor_(web_framework)

ONE LANGUAGE

Node - backJavascript - frontMongodb - database

REUNIÃO DE LIBSSockjs - framework emulador de websocket e responsavel pelo funcioamendto do protocolo DDP

Websocket-based data protocol DDP is like "REST for websockets". Like REST, it is a simple, pragmatic approach toproviding an API. But it is websocket-based, unlike REST, allowing it to be used to deliver live updates as datachanges. Implementation of DDP is simple (it's just a few JSON messages over a websocket) and the spec fits on acouple of pages.

MongoDB - duh

REUNIÃO DE LIBS2Handlebars - template enginePubSub - lib de emissao e escuta de eventos via patter pubsubMiniMongo - API clinet-side que possui a maioria das funcionalidades do mongodb (mongodb no front)

The minimongo package is a reimplementation of (almost) the entire MongoDB API, against an in-memoryJavaScript database. It is like a MongoDB emulator that runs inside your web browser. You can insert data into it andsearch, sort, and update that data.

Connect - modulo node com funcionalidades para trabalhar com protocolo HTTP

SOCKJSSockJS is a browser JavaScript library that provides a WebSocket-like object. SockJS gives you a coherent, cross-

browser, Javascript API which creates a low latency, full duplex, cross-domain communication channel between thebrowser and the web server. Under the hood SockJS tries to use native WebSockets first. If that fails it can use a variety of

browser-specific transport protocols and presents them through WebSocket-like abstractions. SockJS is intended towork for all modern browsers and in environments which don't support the WebSocket protocol -- for example, behind

restrictive corporate proxies. SockJS-client does require a server counterpart:

OS 7 PRÍNCIPIOS DOMETEOR

Data on the wire: Não envie HTML pela rede e sim apenas dados para deixar o cliente decidir como renderizá-lo.One language: Escreva código Javascript em ambas camadas: cliente e servidor.Database anywhere: Utilize uma API de interface única e transparente que te permite acessar o banco de dados tanto nocliente como no servidor.Latency compensation: No cliente é usado prefetching e model simulation na API do banco de dados para atingir latênciazero no acesso de seus recursos.Full-Stack Reactivity: Por default tudo funciona em real-time. E todas as camadas da aplicação adotam o paradigmaorientado à eventos, que é herdado do Node.js.Embrace the ecosystem: Totalmente open-source o Meteor possui suas convenções pelo qual agrega novos valores aoinvés de ser ferramenta uma que vai substituir outros frameworks atuais.Simplicity equals Productivity: Seja produtivo! Desenvolva de forma simplificada, utilize APIs fáceis de aprender eimplementar, afinal essa será a melhor forma de criar uma aplicação.

LIVE RELOAD!But only on the server ://

TESTES :SVELOCITY

sanjo:jasmine - Write client and server unit and integration tests with Jasmine.mike:mocha - A Velocity version of mocha-web. Runs mocha tests in the Meteor context which is great for integrationtesting.xolvio:cucumber - Use BDD Gherkin-syntax cucumber to test your app. Includes PhantomJS and Selenium as well asSauceLabs support.rsbatech:robotframework - Robot Framework end to end test integration using Selenium and many other test libraries

Big news! Work is underway on Velocity, the official testing framework for Meteor. July 14, 2014 By Alice Yu

WHEN NOT TO USEMETEOR

Meteor is best suited for Single-Page Apps, and less suited: relational mindsFor graphics-heavy mobile games, it may be better to build a native appFor applications with very large numbers of concurrent connections, Meteor might require larger amounts of RAMScaling - if you need Facebook-scale now, Meteor is not the best solution LOL

INTEGRAÇAO COM PACKAGE.JSONBUILT IN MONGODB AND SERVERObs: Ids zuados! Não já ObjectId

WTF!

REALTIME DESGRAÇA!

WHAT BELONGS TOWHO

MONGO ON THEFRONT!

insecure: Meteor also has a special "insecure mode" for quickly prototyping new applications. In insecure mode, if youhaven't set up any allow or deny rules on a collection, then all users have full write access to the collection. This is the onlyeffect of insecure mode.Autopublish: self explained

Obs: Remova insecure e autopublish quanto antes do seu projeto

LATENCYCOMPENSATION

There are only two places where you can do a writeoperation to a data store: inside a method call or directly via

a local collection.

SEM LATENCY COMPENSATION :(// File: /client/app.js

Template.addPost.events({ "click button": function() { var title = $('#title').val(); var content = $('#content').val();

var post = { title: title, content: content };

Meteor.call('addPost', post, function(err, postId) { if(err) { alert(err.reason); } else { Router.go('/post/' + postId);

COM LATENCY COMPENSATION :)// File: /client/app.jsTemplate.addPost.events({ "click button": function() { var title = $('#title').val(); var content = $('#content').val();

var post = { title: title, content: content, _id: Random.id() };

Meteor.call('addPost', post, function(err) { if(err) { alert(err.reason); } });

PUBSUBMeteor.publish('Clients', function(){ return Clients.find({});});

Meteor.subscribe("Clients");
