Upgrading

Because there are many breaking changes an upgrade is not that easy. There are many edge cases this guide does not cover. We accept PRs to improve this guide.

From v3 to v4

  • The CrawlObserver and CrawlProfile are upgraded from interfaces to abstract classes, so you have to convert your old observers and profiles. crawled now receives every successfully crawled uri, crawlFailed every failed one.

From v2 to v3

  • PHP 7.1 is now required as a minimum version.
  • Instead of using our custom \Spatie\Crawler\Url object, we're now using the Psr\Http\Message\UriInterface. Custom Profiles and Observers will need to be changed to have the correct arguments and return types. We're using \GuzzleHttp\Psr7\Uri as the concrete URI implementation.
