A generic Redux Toolkit slice factory that generates actions, selectors, and reducers for CRUD operations on entities. It supports nested entities and provides a consistent pattern for state management across the application. This component is self-contained and can be extracted into any Redux project to reduce boilerplate for entity management.

An algorithm for computing the new order of a sortable list after a drag-and-drop operation. It handles insertion, removal, and reordering with minimal state changes. The implementation is framework-agnostic and can be reused in any project requiring drag-and-drop list reordering.

A utility that calculates the optimal position for a popup or tooltip relative to an anchor element, with nudge and flip logic to keep it within the viewport. It is a pure function with no dependencies on the rest of the codebase, making it easily reusable in any frontend project.

A type-safe event emitter implementation that enforces event names and payload types at compile time. It provides a simple API for subscribing and emitting events without external dependencies. This pattern is reusable in any TypeScript project needing typed event handling.
