Your LangGraph agent runs perfectly on your laptop. Then you deploy it. The conversation memory vanishes on restart. Refunds approve themselves with no human in sight. And when it breaks in front of a customer, you have no way to see why.
Most LangGraph books either stop at the RAG demo or sprawl across the entire LangChain ecosystem. This one does neither. LangGraph @ Work is the production half that almost nobody teaches — and it gives you the code.
This is a hands-on, build-it guide that takes you from the agent mental model to a fully operational multi-agent system in Python. One real-world example, developed end-to-end, every line in your hands by the finish.
What you'll build. A complete customer service agent. A supervisor routes requests to specialized catalog and billing subagents. A refund flow pauses for human approval via interrupt(). PostgreSQL-backed memory persists across sessions. A FastAPI gateway handles concurrent async requests. You run it. You ship it.
What you'll learn:
- LangGraph state, nodes, and edges built from primitives — not from black-box helpers
- The supervisor pattern with @tool-wrapped subagents that keep context windows small as the system grows
- Where to place interrupt() for human-in-the-loop, and why node-versus-tool is a real architectural decision
- The InMemoryStore-to-PostgresStore swap, with the connection pooling and setup() idempotency production demands
- Full observability with LangSmith: trace every decision, run evaluations in CI, and build an LLM-as-judge with a working rubric
- Testing graphs with mocked LLM calls and in-memory SQLite fixtures
- Async FastAPI deployment with ainvoke(), lifespan management, and CORS allowlists
- Dependency security and the recent LangChain CVEs, with the exact versions to pin in requirements.txt
Free source code. Every line of the worked example is a free download — modules, database schema, setup scripts, sample data, and the complete security-pinned requirements.txt.
Written for the individual engineer who has to ship it, not the team still discussing it. Software engineers, ML engineers, AI engineers, solutions architects, and the rising class of Forward-Deployed Engineers building real AI products, not demos.
About the author. John Moore is a learning designer and technical author with two decades of experience building engineering curricula for major cloud platforms, including the most recent Architecting on AWS update. He writes for developers who want to move fast and build things that work.

Information regarding the right of withdrawal
Statutory right to withdraw
You have the right to withdraw from this contract within 14 days without giving any reason.
The withdrawal period will expire after 14 days from the day on which you acquire, or a third party other than the carrier and indicated by you acquires, physical possession of the last good or the last lot or piece.
To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.
To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
We may withhold reimbursement until we have received the goods back, or you have supplied evidence of having sent back the goods, whichever is the earliest.
You shall send back the goods or hand them over to California Books, Fort Wayne, Indiana, U.S.A., without undue delay and in any event not later than 14 days from the day on which you communicate your withdrawal from this contract to us. The deadline is met if you send back the goods before the period of 14 days has expired. You will have to bear the direct cost of returning the goods. You are only liable for any diminished value of the goods resulting from the handling other than what is necessary to establish the nature, characteristics and functioning of the goods.
Exceptions to the right of withdrawal
The right of withdrawal does not apply to:
- The delivery of newspapers, journals or magazines with the exception of subscription contracts; and
- The supply of digital content which is not supplied on a tangible medium (e.g. on a CD or DVD) if you accepted when you placed your order that we could start to deliver it, and that you could not withdraw once delivery had started.
