Null-Object (NPM Package)

 |  Deliverables

A runtime-safe, polymorphic noop object that absorbs all method calls, property accesses, and assignments—without side effects or the need for conditionals.

Replace Optional Dependencies with a Silent Stand-In 1

Motivation

Applications often rely on optional services—loggers, plugins, metrics—that may be disabled or unavailable in certain environments. Instead of littering the codebase with if checks, this utility provides:

  • Clean fallbacks: Replace real implementations with a zero-behavior object.
  • Type-safe defaults: Maintain proper interfaces while safely doing nothing.
  • Simpler runtime logic: Avoid conditional branching and reduce code noise.

Key Features

  • Universal trap – Safely handles any method, property, or nested access.
  • Chaining support – Always returns itself to enable method chaining.
  • Assignment-safe – Accepts any property assignment silently.
  • noop() bundled – A utility no-operation function included for convenience.
  • TypeScript-native – Fully typed interface with JSDoc support.
  • No dependencies – Lightweight, production-ready.
