A simple Typescript Domain Driven Design Toolkit to help you create your aggregates, domain events, command handlers and other stuff.

Alert engine + orchestrator: pure rule evaluation (host-driven clock tick, no scheduler in core) wiring domain events to the @bimetal/alert-data lifecycle and pluggable @bimetal/channel delivery. Idempotent — replay never re-delivers.

NestJS dynamic module for producing domain events based on local Nest CQRS Events

Single source of truth for Demystify cross-cutting wire contracts: error taxonomy, domain events, canonical headers, key format/hashing, currency helpers, and key-introspection schemas. Leaf package, zod-only.

Layered storefront analytics (GTM dataLayer) with reusable domain events for reviews, forms, and more.

A Typescript library for managing domain events, providing integration with React,React Native , and supporting DDD use cases. Designed to work in Typescript projects.

Boring Postgres-backed notification engine. Turns domain events into delivered emails via provider adapters.

Effect-native web crawler for TypeScript — typed results, domain events, resumable crawls, configurable retry and user-agent strategy

ACP v1 agent/server adapter. Bridges the official `@agentclientprotocol/sdk` transport to the `@stackory/tiny-agent` Host/Session SDK: it maps ACP requests and notifications to SDK calls, and maps SDK domain events to ACP `session/update` notifications.

The node core libs for in browser usage.

Runtime core for tiny-agent: turn orchestration, hook composition, domain events and the storage/tool ports the SDK composes. It owns the single `@earendil-works/pi-agent-core` `Agent` seam and stays free of wire, SQLite and MCP concerns.

Agnostic cloud event bus for Stone.js: emit domain events to local and/or cloud targets, and route incoming bus events to @OnBusEvent handlers via the key-router on any simple cloud adapter. EventBridge driver.

Generic, I/O-free DDD tactical kernel: typed ids, entities, aggregate roots, domain events, repositories, gateways, the unit of work, and specifications.

the component library for events

Transactional outbox for NestJS: record domain events inside the caller's DB transaction, then relay them at-least-once to a broker. Zero runtime dependencies

TypeScript event library for typed event emitters, domain events, and pub/sub messaging with caching

This npm package provides a set of utilities for building domain-driven design (DDD) applications. It includes essential classes and interfaces for defining aggregates, entities, value objects, domain events, decorators, use cases, and error handling. The

EventEmitter3 focuses on performance while maintaining a Node.js AND browser compatible interface.

Boring Postgres-backed immutable audit log. Turns domain events into an append-only 'who did what, to what, when' trail.

Map (domain) events between your application and event store.
