About System crawler
🕸 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.

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
