Ayakashi is a web scraping library for Node.js that allows developers to easily extract structured data from websites. It is built on top of the popular "puppeteer" library and provides a simple and intuitive API for defining and querying the structure of a website.

Features:

  • Powerful querying and data models
    Ayakashi's way of finding things in the page and using them is done with props and domQL. Directly inspired by the relational database world (and SQL), domQL makes DOM access easy and readable no matter how obscure the page's structure is. Props are the way to package domQL expressions as re-usable structures which can then be passed around to actions or to be used as models for data extraction.
  • High level builtin actions
    Ready made actions so you can focus on what matters. Easily handle infinite scrolling, single page navigation, events and more. Plus, you can always build your own actions, either from scratch or by composing other actions.
  • Preload code on pages
    Need to include a bunch of code, a library you made or a 3rd party module and make it available on a page? Preloaders have you covered.

Roach is a complete web scraping toolkit for PHP. It is heavily inspired by the popular Scrapy package for Python.

Roach allows us to define spiders that crawl and scrape web documents. Roach isn’t just a simple crawler, but includes an entire pipeline to clean, persist and otherwise process extracted data as well.

Just like scrapy, Roach supports: - Middlewares - Item Pipelines - Extendibility through Plugins

It’s your all-in-one resource for web scraping in PHP.

Example Use


const ayakashi = require("ayakashi");
const myAyakashi = ayakashi.init();

// navigate the browser
await myAyakashi.goTo("https://example.com/product");

// parsing HTML
// first by defnining a selector
myAyakashi
    .select("productList")
    .where({class: {eq: "product-item"}});

// then executing selector on current HTML:
const productList = await myAyakashi.extract("productList");
console.log(productList);
<?php

use RoachPHP\Http\Response;
use RoachPHP\Spider\BasicSpider;

class RoachDocsSpider extends BasicSpider
{
    /**
     * @var string[]
     */
    public array $startUrls = [
        'https://roach-php.dev/docs/spiders'
    ];

    public function parse(Response $response): \Generator
    {
        $title = $response->filter('h1')->text();

        $subtitle = $response
            ->filter('main > div:nth-child(2) p:first-of-type')
            ->text();

        yield $this->item([
            'title' => $title,
            'subtitle' => $subtitle,
        ]);
    }
}
