Jankx Plugin Activation

A modern, PSR-4 compliant WordPress plugin activation library, refactored from TGM Plugin Activation.

Features

• PSR-4 Compliant: Clean namespace structure with Jankx\PluginActivation\
• SOLID Principles: Separated concerns into focused, single-responsibility classes
• DRY Code: Extracted repeated logic into reusable methods
• Backward Compatible: Works with existing TGMPA code via class aliases
• Lightweight: Custom autoloader, no Composer vendor folder required
