Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Scrapy puppeteer plugin

Este es un servicio que provee la funcionalidad de puppeteer para la libreria Scrapy . Permite el uso de plugins de puppeteer-extra-plugin, inyectandolos en una propiedad plugins dentro de providers y unicamente es una capa sobre el modulo de puppeteer. Este servicio es el que se usa en el ejemplo de uso.

Instalacion

Antes debe tener instalado la libreria scrapy para poder utilizarlo en ella

    npm i @xkairo/scrapy

Despues de instalar scrap, ya puede instalar esta libreria

    npm i @xkairo/scrapy-puppeteer-plugin

Configuracion

Para agregar una configuracion a puppeteer debe usar un provider, en el cual agregaras los plugins propios de puppeteer-plugin-extra y la configuracion de la instancia de puppeteer. El provider debera agregarlo en la configuracion de scrapy.

    export const puppeteerProvider: Registable = {
        plugins: {
            useValue: [],
        },
        config: {
            useValue: {
                headless: true,
            },
        },
    };
    const filepath = join(__dirname, "result.csv");
    const config: ScraperConfigInterface<UserInterface> = {
      uploaders: [LocalUploader],
      processors: [CsvProcessor],
      scrapers: [PageScraper],
      services: [Puppeteer], // <---- Note como aca se agrega el servicio para luego injectarlo
      providers: [
        puppeteerProvider, // <---- Note como se carga el provider con la configuracion
        {
          filepath: {
            useValue: filepath,
          },
        },
      ],
      exceptionHandler: ExceptionHandler,
    };

    const scraper = new Scraper(config);

    await scraper.init();

Uso

Hay que tener en cuenta que la libreria scrapy utiliza un sistema de injeccion de dependencias con inversion de control, por lo que usted no deberia instanciar este servicio, sino que injectarlo.

    constructor(
        @Inject(Puppeteer) private puppeteerService: Puppeteer
    ) {}

Luego podra acceder al browser con getBrowser:

    async commonFunction() {
        const browser = await this.puppeteerService.getBrowser(); // <---- Obtenemos un browser de puppeteer

        browser.newPage() // <---- Puedes usar cualquier metodo de browser
    }
