texample
Run the JavaScript code blocks in your README as live tests. Keeps documentation honest by failing CI when an example breaks.
BPMN engine ecosystem
The BPMN 2.0 engine and its building blocks. Used together to execute, extend, and serialize workflow processes in JavaScript and TypeScript.
bpmn-engine
BPMN 2.0 execution engine for Node.js and the browser. Runs business processes defined in standard BPMN XML, with TypeScript types, ESM/CJS support, and granular debug logging.
bpmn-middleware
Express middleware that runs the BPMN engine inside a Node.js HTTP application. Handles process state, call activities, and workflow orchestration over REST.
bpmn-elements
Executable workflow elements that implement the BPMN 2.0 specification. The building blocks behind bpmn-engine, usable on their own to assemble custom runtimes.
smqp
Synchronous in-process message broker with exchanges, queues, topics, and ack/nack semantics. Underpins bpmn-engine and bpmn-elements without pulling in a real broker dependency.
moddle-context-serializer
Serialize bpmn-moddle contexts to JSON for storage and process state recovery. Pairs with bpmn-engine to persist long-running workflows.
@onify/flow-extensions

Worth a look
Packages I've contributed to or recommend — same dependency-light spirit, different repos.
@aller/express-swagger
Adds a Swagger / OpenAPI v3 specification to an Express application, derived automatically from the types of the routes registered on the app.
@aller/pino-gcp-transport
Pino transport that emits Google Cloud structured logs to stdout. Drop-in for services running on GKE, Cloud Run, or anywhere GCP scrapes JSON logs.
@onify/fake-amqplib
In-memory fake of the amqplib RabbitMQ client for unit tests. Drop-in API-compatible replacement so tests don't need a live broker.
chronokinesis
Time-travel for testing time-dependent code. Freeze, travel, and reset the clock — works with Date, hrtime, performance, and timezones.
