🕸 Crawl the web using PHP 🕷This package provides a class to crawl links on a website. Under the hood Guzzle promises are used to crawl multiple urls concurrently.Because the crawler can execute JavaScript, it can crawl JavaScript rendered sites. Under the hood Chrome and Puppeteer are used to power this feature.Support usWe invest a lot of resources into creating best in class open source packages. You can support us by buying one of our paid products.We highly appreciate you sending us a postcard from your hometown, mentioning which of our package(s) you are using. You'll find our address on our contact page. We publish all received postcards on our virtual postcard wall.InstallationThis package can be installed via Composer:composer require spatie/crawlerUsageThe crawler can be instantiated like thissetCrawlObserver() ->startCrawling($url);">use Spatie\Crawler\Crawler;Crawler::create() ->setCrawlObserver(class that extends \Spatie\Crawler\CrawlObservers\CrawlObserver>) ->startCrawling($url);The argument passed to setCrawlObserver must be an object that extends the \Spatie\Crawler\CrawlObservers\CrawlObserver abstract class:namespace Spatie\Crawler\CrawlObservers;use GuzzleHttp\Exception\RequestException;use Psr\Http\Message\ResponseInterface;use Psr\Http\Message\UriInterface;abstract class CrawlObserver{ /* * Called when the crawler will crawl the url. */ public function willCrawl(UriInterface $url, ?string $linkText): void { } /* * Called when the crawler has crawled the given url successfully. */ abstract public function crawled( UriInterface $url, ResponseInterface $response, ?UriInterface $foundOnUrl = null, ?string $linkText, ): void; /* * Called when the crawler had a problem crawling the given url. */ abstract public function crawlFailed( UriInterface $url, RequestException $requestException, ?UriInterface $foundOnUrl = null, ?string $linkText = null, ): void; /** * Called when the crawl has ended. */ public function finishedCrawling(): void { }}Using multiple observersYou can set multiple observers with setCrawlObservers:setCrawlObservers([ , , ... ]) ->startCrawling($url);">Crawler::create() ->setCrawlObservers([ class that extends \Spatie\Crawler\CrawlObservers\CrawlObserver>, class that extends \Spatie\Crawler\CrawlObservers\CrawlObserver>, ... ]) ->startCrawling($url);Alternatively you can set multiple observers one by one with addCrawlObserver:addCrawlObserver() ->addCrawlObserver() ->addCrawlObserver() ->startCrawling($url);">Crawler::create() ->addCrawlObserver(class that extends \Spatie\Crawler\CrawlObservers\CrawlObserver>) ->addCrawlObserver(class that extends \Spatie\Crawler\CrawlObservers\CrawlObserver>) ->addCrawlObserver(class that extends \Spatie\Crawler\CrawlObservers\CrawlObserver>) ->startCrawling($url);Executing JavaScriptBy default, the crawler will not execute JavaScript. This is how you can enable the execution of JavaScript:executeJavaScript() ...">Crawler::create() ->executeJavaScript() ...In order to make it possible to get the body html after the javascript has been executed, this package depends onour Browsershot package.This package uses Puppeteer under the hood. Here are some pointers on how to install it on your system.Browsershot will make an educated guess as to where its dependencies are installed on your system.By default, the Crawler will instantiate a new Browsershot instance. You may find the need to set a custom created instance using the setBrowsershot(Browsershot $browsershot) method.setBrowsershot($browsershot) ->executeJavaScript() ...">Crawler::create() ->setBrowsershot($browsershot) ->executeJavaScript() ...Note that the crawler will still work even if you don't have the system dependencies required by Browsershot.These system dependencies are only required if you're calling executeJavaScript().Filtering certain urlsYou can tell the crawler not to visit certain urls by using the setCrawlProfile-function. That function expectsan object that extends Spatie\Crawler\CrawlProfiles\CrawlProfile:/* * Determine if the given url should be crawled. */public function shouldCrawl(UriInterface $url): bool;This package comes with three CrawlProfiles out of the box:CrawlAllUrls: this profile will crawl all urls on all pages including urls to an external site.CrawlInternalUrls: this profile will only crawl the internal $319.99In stock Description Additional information Brand DescriptionDiscover the Everest Ascent Rock Crawler, a culmination of extensive research, customer feedback, and cutting-edge engineering that delivers outstanding performance right out of the box.
