jhipster-kafka

jhipster-kafka is a skill for Claude Code, Codex from bdiasti/maestro-bundle-cli. It costs 41 tokens per session (1,628 once invoked), scanned A, original, MIT.

A setup guide for Apache Kafka, a system that lets services send messages to one another asynchronously, in JHipster microservices.

In plain words
What is it for?
Use it to run Kafka with Docker Compose, define event messages, create message producers and consumers, make consumers safe to retry, and configure dead letter queues.
Why use it?
It helps separate services communicate through events without waiting for one another, while providing a way to handle failed messages.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

jhipster-kafka scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Kafka in JHipster Microservices

Configure Apache Kafka for asynchronous event-driven communication between JHipster microservices using domain events, producers, consumers, and dead letter queues.

When to Use

  • When setting up asynchronous messaging between services
  • When implementing domain events (DemandCreated, TaskCompleted, etc.)
  • When creating Kafka producers and consumers
  • When configuring dead letter queues for failed messages
  • When designing event schemas

Available Operations

  1. Set up Kafka with Docker Compose
  2. Define domain events as Java records
  3. Create Kafka producers
  4. Create idempotent consumers
  5. Configure dead letter queues

Multi-Step Workflow

Step 1: Start Kafka with Docker Compose

# docker-compose/kafka.yml
services:
  zookeeper:
    image: confluentinc/cp-zookeeper:7.5.0
    environment:
      ZOOKEEPER_CLIENT_PORT: 2181

  kafka:
    image: confluentinc/cp-kafka:7.5.0
    depends_on:
      - zookeeper
    ports:
      - "9092:9092"
    environment:
      KAFKA_BROKER_ID: 1
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
      KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://kafka:29092,PLAINTEXT_HOST://localhost:9092
      KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: PLAINTEXT:PLAINTEXT,PLAINTEXT_HOST:PLAINTEXT
      KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1
# Start Kafka
docker-compose -f docker-compose/kafka.yml up -d

# Verify Kafka is running
docker-compose logs kafka | tail -5

# List topics
docker exec -it kafka kafka-topics --list --bootstrap-server localhost:29092

Step 2: Design Topics by Bounded Context

Topic Producer Consumer Events
demand-events demand-service agent-service, tracking-service DemandCreated, DemandDecomposed
agent-events agent-service demand-service, tracking-service AgentAllocated, TaskCompleted
bundle-events bundle-service agent-service BundleUpdated, SkillAdded
tracking-events tracking-service gateway (WebSocket) MetricsUpdated

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
