Disposables let you safely compose resource disposal semantics

A collection of helpers that aim to simplify using reactive primitives outside of reactive roots, and managing disposal of reactive roots.

Async construction and disposal lifecycle primitives — the missing symbol for constructing asynchronous things.

The ioc runtime engine: DiBuilder, scopes, resolution, captive-dependency protection, factories, and native disposal.

Structured concurrency scopes for silvery apps — cancellation, disposal, lifecycle

Agent Skill: three.js scene setup, rendering, loaders, performance, and disposal.

A disposable base class and minimal set of interfaces to properly implement an object disposal pattern.

Proof-of-concept implementation of the Resource Disposal Syntax Sugar TC39 proposal (Stage 0)

Lightweight module for handling disposal of allocated resources via:

The ioc runtime engine: DiBuilder, scopes, resolution, captive-dependency protection, factories, and native disposal.

High-performance, decorator-free IoC container for Node.js — sync inject(), explicit lifetimes, TC39-native disposal.

Date and time utilities at your disposal

OpenCode plugin that disposes idle workspaces and reacts to session disposal events.

Download multipart files with open file descriptor limits and file disposal

Zero-GC FinalizationRegistry helper. Shared disposal registry with unregister semantics, tag-based collection reporting, and error routing.

Chemical safety intelligence for AI-assisted experiment design — 23 tools for compatibility, hazard, PPE, storage, waste disposal, mixing order, exposure limits, transport classification, regulatory compliance (23 lists, 10 regions), SDS version diff, PDF

The data driving the City's waste disposal helper app

ESLint plugin for TempoTS to catch common signal disposal issues

Deterministic imperative three.js scenes with an LLM-first procedural asset toolkit, fixed-step physics, and explicit disposal.

Foundational primitives shared across @youneed packages: shared types, the class-metadata registry (TC39 addInitializer + WeakMap, esbuild/tsx-safe), and disposal helpers.
