NgxMatFacetToolkit

NgxMatFacetToolkit is a comprehensive Angular library for implementing facet filtering in web applications. It provides a set of reusable, Material-styled components to create dynamic filtering interfaces that allow users to drill down into datasets using multiple criteria.

Key Features

• Multiple Facet Types — Supports text, boolean, category (single/multi-select), typeahead, date, date range, and numeric filters.
• Material Design Integration — Seamlessly integrates with Angular Material for consistent theming, typography, and density controls.
• Flexible Configuration — Offers extensive configuration options for storage strategies, identity management, and UI behavior via both global providers and component inputs.
• State Persistence — Includes built-in support for session and local storage to maintain filter state across page reloads.
• Preset Management — Allows saving and loading of filter presets with customizable storage backends.
• Observable Data Sources — Supports asynchronous data loading for category options and typeahead suggestions using RxJS.
• Theme Customization — Provides SCSS mixins for full theming control, including dark mode and custom variable overrides.

Philosophy

The toolkit is designed to be a robust, standalone solution that embraces Angular's modern standalone architecture while maintaining deep integration with the Material Design system for a polished, accessible user experience.
