Semalt: Node.js y AngularJS (JavaScript Framework) en Web Scraping

Web raspado es el proceso de extracción de información de la World Wide Web. Se ha desarrollado una gran cantidad de software, herramientas y técnicas para eliminar datos de páginas web. De forma similar, se utilizan diferentes lenguajes de programación como Ruby, JavaScript, Node.js, Python, PHP y C ++ para extraer información de la red. JavaScript evolucionó más allá del lenguaje de scripting del lado del cliente para convertirse en un lenguaje de programación útil e integral. Es ampliamente utilizado para construir raspadores web y aplicaciones del lado del servidor. De forma similar, Node.js se usa para desarrollar aplicaciones tanto del lado del servidor como del lado del cliente y raspadores de pantalla interactivos. Tanto Node.js como JavaScript tienen sus propias características distintivas. En el transcurso del artículo vamos a hablar sobre sus similitudes y roles en el web scraping.

Una descripción general de JavaScript en el raspado web:

Este es el lenguaje basado en prototipos que se utiliza principalmente para crear aplicaciones de escritorio y raspadores de pantalla. Es fácil de usar y tiene un par de códigos útiles para beneficiarse. AngularJS es el marco de JavaScript, que es mantenido por nada menos que Google. Puede agregar fácilmente AngularJS a páginas HTML y extraer datos de ellas. Este marco de JavaScript ayuda a eliminar información de sitios dinámicos y es compatible con los componentes y la arquitectura MVW (Model-View-Whatever). Es mejor conocido por crear aplicaciones basadas en datos.

AngularJS - Un marco de JavaScript:

Nos proporciona el MVCA sin problemas (Model View Control Architecture) que ayuda a apuntar a sitios dinámicos y elimina datos de ellos. Además, podemos construir cualquier tipo de raspador de pantalla utilizando este marco sin necesidad de códigos sofisticados. Los desarrolladores pueden usar este marco de JavaScript para arreglar su software de raspado web y construir aplicaciones web a gran escala Nos permite separar los elementos MVC y facilita nuestro trabajo. Algunas de sus características y opciones más distintivas son filtros, enlaces automáticos de datos y directivas. Se puede integrar con otros programas UI y puede manipular DOM. Además, te permite para escribir código HTML personalizado y es adecuado para desarrolladores y programadores, lo que les permite crear contenido dinámico rápidamente.

NodeJS en web scraping:

Node.js es el entorno de código abierto que ayuda desarrollar redes y aplicaciones en el lado del servidor PD. Nos proporciona una biblioteca interactiva de módulos de JavaScript y puede simplificar el desarrollo de raspadores de pantalla.

Características de Node.Js:

Puede escalar fácilmente las aplicaciones Node.js de dos maneras: escala vertical y escalado horizontal. Ambos ayudan a construir una pantalla de alto perfil o raspadores de datos. Node.js admite pruebas unitarias y podemos usarlo para probar los códigos HTML. Además, tiene diferentes API, que ayudan a crear servidores DNS, servidores HTTP y servidores TCP. Node.js usa el motor de JavaScript para ejecutar códigos diferentes y le facilita el raspado del contenido web dinámico, lo que garantiza su precisión y calidad.

Conclusión:

AngularJS y Node.js son frameworks de código abierto, que se utilizan para desarrollar las aplicaciones del lado del servidor y los web scrapers. Son adecuados para programadores y son bastante similares en la forma en que trabajan y la arquitectura. Puede almacenar los datos recortados en sus bases de datos interactivas o descargarlos a su disco duro al instante. Además, puede usarlos para crear diferentes herramientas de JavaScript y extraer contenido de un sitio web completo.
