Node.js es un entorno de programación en el servidor basado en JavaScript que utiliza un modelo de E/S asíncrono y basado en eventos. Permite ejecutar JavaScript en el servidor, lo que hace que sea altamente escalable y adecuado para aplicaciones en tiempo real.

Slides from the NestJS MasterClass.
We learned how to build JavaScript server-side applications with NestJS - A progressive NodeJS framework built with TypeScript.

HTTP messages are how data is exchanged between a server and a client. There are two types of messages: requests sent by the client to trigger an action on the server, and responses, the answer from the server.

An OpenEJB presentation on "Apache TomEE"
TomEE aims to provide a fully certified Java EE 6 Web profile stack based on Tomcat, allowing you to use Java EE features in your lightweight Tomcat applications.
A stack that's assembled and maintained by the Apache OpenEJB project
An intro to React Native using react-native cli, styled components, react-navigation, and an an introduction to the react native ecosystem.
Example repo: https://github.com/ladyleet/fluentConf2

This talk introduces Spring's REST stack - Spring MVC, Spring HATEOAS, Spring Data REST, Spring Security OAuth and Spring Social - while refining an API to move higher up the Richardson maturity model
Slides presented at the Vue.js meetup in Paris the 3rd of December 2016.
Nuxt.js is a minimalist framework for server-rendered Vue.js applications.
https://nuxtjs.org
Here I covered the cores of Apache and also discuss each and every core. Virtual host, resistance server process some protocols like HTTP, SMTP, DNS FTP, are also be highlighted.
Focus on some installing part of apache.

Ryan Hall & Peter Dolukhanov joint managing directors at mobile specialists Nice Agency talked at the BIMA Evening Briefing on 'Beyond acquisition – how do you retain users on mobile?'
As brands spend more time and money on acquiring mobile users, not enough focus is put on retaining them.
Peter and Ryan looked at mobile engagement and retention, exploring the challenges of creating a compelling mobile experience, outlining why a cross-device user journey is key and the importance of a communications strategy to drive behavioural change for repeat usage.

Better serving members using one social spotMicrosoft
Since its founding nearly 90 years ago, Nationwide has gone from a small auto insurer for farmers to one of the largest insurance and financial services companies in the world. Through it all, one thing has stayed constant: a focus on serving customers, which it considers members of the Nationwide family. Today that members-first policy is supported by Yammer social networking technology, including a SharePoint integration dubbed Spot—as in, the spot to get everything done.

HTTP (Hyper text Transfer Protocol, o Protocolo de Trasferencia de
Hipertext), es el método utilizado para transferir o transportar información
en la Red Mundial (WWW, World Wide Web). Su propósito original fue el
proveer una forma de publicar y recuperar documentos HTML.
El desarrollo del protocolo fue coordinado por World Wide Web Consortium
y la IETF (Internet Engineering Task Force, o Fuerza de Trabajo en Ingeniería de Internet),
culminando con la publicación de varios RFC (Request For Comments), de entre los que
destaca el RFC 2616, mismo que define la versión 1.1 del protocolo, que es el utilizado hoy en
día.

2. Node.js es un entorno de programación
en la capa del servidor basado en
Javascript, con E/S de datos desde una
arquitectura orientada a eventos y basado
en el motor Javascript V8.
V8 es un interprete, compilador y ejecutor
de código Javascript.
3. “Node.js es muchas cosas, pero en
esencia es una forma de ejecutar
JavaScript fuera del navegador web” –
Ryan Dahl – 2009.
Node.js le permite a JavaScript ser
aplicado en muchos contextos más, en
particular en los servidores web.
4. JavaScript es un lenguaje orientado a
eventos y node utiliza esta característica
para producir servidores altamente
escalables.
Con una arquitectura llamada “bucles de
eventos”, hace que la programación del
servidor node sea altamente escalable y a
su vez fácil y segura.
5.
6.
7.
8.
9. Node.js incorpora varios "módulos básicos"
compilados en binario, como por ejemplo el
módulo Net, que proporciona una capa para
programación de red asíncrona y otros
módulos fundamentales, como por ejemplo
Path, FileSystem, Buffer, Timers, y el de
propósito más general Stream.
10.
11. Dentro de la carpeta nodejs crearemos la carpeta htdocs, dentro de ella
crearemos nuestro Script para montar un servidor web.
var http = require('http'); //importamos el modulo "http"
http.createServer(function (req, res) { // creamos un servidor
res.writeHead(200, {'Content-Type': 'text/plain'}); //escribimos la cabecera de
nuestro documento
res.end('Bienvenido coneccion #‟ +req.socket.server._connections+‟n'); //
enviamos un texto como salida
}).listen(80, „localhost'); // el servidor comienza a escuchar las peticiones
// que se le hagan desde la siguiente dirección: http://localhost
console.log('Servidor corriendo en http://localhost:80/');
13. Síncrono:
var result = db.query(‘select * from usuario’);
// use result
Asíncrono:
db.query(‘select * from usuario’, function(result){
// use result
});
14. HTTP: es half-duplex (su tráfico fluye en una
sola dirección a la vez).(Nextel)
WebSocket: es una tecnología web que
establece canales de comunicacion bi-
direccional(full-duplex) usando una simple
conexión TCP.
