Transient Control

DFM-Transients is a WordPress plugin that enhances the built-in Transients API by providing a registration framework, asynchronous updates, and advanced expiration management. It is designed for developers who need reliable, maintainable caching for complex data.

• Registration API: Register transients with a declarative pattern similar to custom post types. Define callback, expiration, cache type (transient, post_meta, term_meta, user_meta), and update hooks.
• Soft Expiration: Set soft_expiration to true to serve stale data while regenerating it in a background process, reducing page load times.
• Async Updates: Automatically refresh transient data when specific hooks fire, with optional condition callbacks to avoid unnecessary regeneration.
• Retry System: If a data fetch fails (e.g., external API), the plugin serves stale data and retries with exponentially increasing intervals, preventing cache stampedes.
• CLI Commands: Manage transients via WP-CLI. List, get, set, and delete transients and their modifiers from the command line for easy debugging and maintenance.
