drupal-check is a static analysis tool that checks Drupal code for deprecated API usage and other issues. It helps prepare modules for Drupal version upgrades by identifying code that needs updating.
The tool uses PHPStan for static analysis with Drupal-specific rules. It detects usage of deprecated functions, classes, and services that will be removed in future Drupal versions.
drupal-check is essential for maintaining Drupal modules and ensuring compatibility with upcoming releases.
