NodeJs<\/h2>\n

La p\u00e1gina oficial <\/a>nos da la siguiente descripci\u00f3n sobre NodeJs :<\/p>\n

\n

NodeJs es una plataforma constru\u00edda encima del entorno de ejecuci\u00f3n javascript de Chrome para f\u00e1cilmente construir r\u00e1pidas, escalables aplicaciones de red.<\/p>\n

Nodejs usa un modelo de E\/S no bloqueante dirigido por eventos que lo hace ligero y eficiente, perfecto para aplicaciones data-intensive en tiempo real\u201d<\/p>\n<\/blockquote>\n

Es decir, que nos permite realizar complejas aplicaciones en torno al lenguaje javascript, del lado del servidor<\/p>\n

Con lo cual, los eventos que manejamos, se orientan a la comunicaci\u00f3n de peticiones y respuestas hacia el servidor.<\/p>\n

Surge con el objetivo de superar ciertos inconvenientes para construir aplicaciones que soportasen alta concurrencia de usuarios.<\/p>\n

La idea era evitar saturar los recursos del servidor, ofreciendo una r\u00e1pida y efectiva interacci\u00f3n entre usuario y servidor.<\/p>\n

Qui\u00e9nes utilizan NodeJs ?<\/h2>\n

\"Empresas<\/a><\/p>\n

Empresas como Google, Yahoo, Microsoft, entre otras, usan este tipo de tecnolog\u00eda.<\/p>\n

De esta manera brindan a sus usuarios una buena experiencia y mejores servicios.<\/p>\n

Para ellas representa un ahorro de dinero, ya que disminuyen el n\u00famero de servidores sin perder calidad, recursos, sino mejor\u00e1ndolos.<\/p>\n

Cu\u00e1ndo conviene usar esto?<\/h3>\n

El dilema de usar o no NodeJs depender\u00e1 absolutamente del tipo de web, o aplicaci\u00f3n web que estemos desarrollando. <\/p>\n

Si desarrollamos una aplicaci\u00f3n que deber\u00e1 atender gran n\u00famero de peticiones simult\u00e1neas en tiempo real, sin duda deber\u00edamos utilizar NodeJs <\/p>\n

Naci\u00f3 con este objetivo, se cre\u00f3 para esto, y nos garantiza muchas ventajas su uso en contraposici\u00f3n a otros tipos de servidores.<\/p>\n

Sitios de alto tr\u00e1fico (chats, juegos online o notificaciones en tiempo real), optar\u00e1n por el uso del mismo.<\/p>\n

Evidentemente hay que resaltar a Javascript como un lenguaje que est\u00e1 cobrando notoriedad en el munodo web y mobile a pasos agigantados.<\/p>\n

Desde 2008 han aparecido varios frameworks Javascript como AngularJS, Backbonne, React, etc, gracias a los nuevos desaf\u00edos en la comunicaci\u00f3n.<\/p>\n","protected":false},"excerpt":{"rendered":"
