Semalt: ¿Es jQuery la mejor biblioteca de JavaScript para raspar pantallas?

Feb 05, 2018

jQuery es la biblioteca multiplataforma de JavaScript diseñada para simplificar la creación de scripts en el lado del cliente de HTML. Es seguro decir que jQuery es una de las mejores y ampliamente implementadas bibliotecas de JavaScript. Con esta biblioteca, puede agregar rápidamente efectos de animación a su sitio, raspar documentos web o crear raspadores de pantalla para realizar sus tareas de extracción de datos. También puede crear aplicaciones Android, iOS y web usando el framework de jQuery, Cordova.

El raspado de la pantalla o la extracción de datos es el proceso de robar información o datos de Internet utilizando bots y arañas. La sintaxis de jQuery está diseñada para facilitarle la navegación a través de documentos web, raspar datos, seleccionar elementos DOM, crear animaciones, desarrollar aplicaciones AJAX. Una de las características más distintivas de esta biblioteca de JavaScript es que permite a los desarrolladores y programadores crear raspadores de pantalla avanzados, crear abstracciones para temas y widgets de WordPress. El enfoque modular de jQuery nos permite crear páginas web y aplicaciones potentes y dinámicas.

Otras bibliotecas de JavaScript que valen Su atención:

Diferentes marcos y bibliotecas de JavaScript agilizan el flujo de trabajo, aumentan el desarrollo de raspadores de pantalla y ofrecen mejores características en términos de respuesta diseño. Algunas de las bibliotecas de JavaScript más famosas se tratan a continuación:

1. D3.js

Documentos basados en datos (D3.js) se consideran los mejores y la biblioteca de JavaScript de código abierto más efectiva. Ayuda a construir raspadores web e incluye numerosos complementos creados para dar un vistazo interactivo a su sitio y eliminar datos de la red. Esta biblioteca de JavaScript es compatible con todos los navegadores web y sistemas operativos.

2. Chart.js

Es otra biblioteca JavaScript de código abierto para construir raspadores que tienen características similares a la de Import.io y Octoparse. Sin embargo, puede realizar tareas de raspado web a pequeña escala solo con sus raspadores. Se recomienda este marco de JavaScript para documentación completa, y Chart.js se basa en SVG, en lugar del lienzo HTML5.

3. FusionCharts

Es una biblioteca de gráficos adecuada para desarrolladores y diseñadores. FusionCharts consta de más de 80 tipos de gráficos y miles de mapas, lo que deja muy atrás MetricsGraphics y Google Charts. Con esta biblioteca de JavaScript, no puede crear ningún raspador web ni extraer datos de Internet. Sin embargo, este marco es la elección previa de Oracle, Microsoft, IBM y Google. Además, es compatible con navegadores como IE 6, 7 y 8.

4. Gráficos de Google

Le permite construir cualquier cosa desde los gráficos de líneas simples hasta los mapas arborescentes complejos. Google Charts viene con galerías de gráficos preconstruidos, diferentes opciones de personalización y herramientas de datos. Puede construir raspadores de pantalla básicos utilizando esta biblioteca de JavaScript, pero no puede construir extractores de datos avanzados (como ParseHub y Kimono Labs).

Conclusión

La arquitectura de jQuery le permite crear diferentes plugins y raspadores con facilidad. Es mucho mejor que otras bibliotecas de JavaScript y es adecuado tanto para programadores como para desarrolladores. Otras bibliotecas de JavaScript son útiles para realizar tareas básicas y tienen un número limitado de opciones y características. Sin embargo, todas las bibliotecas de JavaScript mejoran la experiencia del usuario y son compatibles con todos los navegadores web y sistemas operativos. Se están introduciendo nuevas bibliotecas diariamente, pero jQuery nos ayuda a comprender JavaScript de una mejor manera y se usa para desarrollar raspadores de pantalla rápidamente.
