MessageBus implementation in JavaScript

CQRS CommandBus, QueryBus, EventBus and project scaffolding for MyCLI

TypeScript port of swift-kernelee — core dispatch (KernelSymbol / Verb / KernelBuilder / Kernel / CommandBus) + pipes (Pipe / PipeBuilder / compose / run) + fork (parallel fan-out) + Buffer (observable state) + defineCallable (typed port factory, the @cal

CommandBus, QueryBus, and EventBus

Simple CommandBus implementation

OpenTelemetry adapter for @eventfabric/mediator: a CommandBus middleware that emits tracing spans + counters + duration histograms per command, plus observable gauges for the command idempotency table.

This library is inspired by PHP library called SimpleBus (https://github.com/SimpleBus).

Mediator for EventFabric: typed Command envelope, CommandBus, middleware framework (idempotency + logging), IdempotencyStore. Backend-agnostic — pair with @eventfabric/mediator-postgres for PG-backed idempotency and @eventfabric/mediator-opentelemetry for

Distributed Command Bus library with Redis Streams transport, MessagePack serialization, and RPC via LPUSH/BRPOP for DragonflyDB

A modular, type-safe foundation for building expressive, maintainable applications. This package provides core abstractions for domain modeling, HTTP integration, authentication, state management, and more — designed to be framework-agnostic and highly ex

A small library to create, register and execute commands.

Frontend asset tooling for LombokClarion (PHP framework). CSS/JS are vendored under resources/ and content-hashed by `php bin/lombokclarion optimize` — npm is only used to refresh the vendored dist files.

Framework-agnostic event sourcing core primitives

CQRS, event sourcing, and the saga pattern (orchestrated + choreographed) for distributed consistency.
