=============
Using the API
=============

Besides the usage via the TYPO3 backend and the console commands,
there is also a public PHP API. It can be used to execute the cache
warmup directly in PHP code.

..  php:namespace:: EliasHaeussler\Typo3Warming\Service

..  php:class:: CacheWarmupService

    Service to run cache warmup for sites and pages.

    ..  php:method:: warmup($sites, $pages, $limit, $strategy)

        Run cache warmup for given sites and pages.

        :param array $sites: List of site warmup requests.
        :param array $pages: List of page warmup requests.
        :param int|null $limit: Optional cache warmup limit.
        :param \EliasHaeussler\CacheWarmup\Crawler\Strategy\CrawlingStrategy|null $strategy: Optional crawling strategy.
        :returntype: :php:`\EliasHaeussler\Typo3Warming\Result\CacheWarmupResult`
