LangGraph.js Production Deployment Checklist: 23 Things to Verify Before Going Live

LangGraph.js Production Deployment Checklist

Shipping an AI agent to production is not the same as shipping a traditional web service. The failure modes are different, the observability requirements are different, and the consequences of certain failure scenarios — silent wrong decisions, state corruption, infinite retry loops — are more severe than most teams anticipate.

Techseria has done this 180+ times across diverse enterprise environments. This checklist is the distilled result of everything we've learned about what breaks in production.

Section 1: State Persistence and Recovery

1. Checkpoint persistence is configured for the production store. Verify that the production LangGraph.js graph is configured with the production checkpointer (PostgreSQL, Cosmos DB, or your chosen store) — not the development in-memory checkpointer.

2. Checkpoint storage is independently backed up. 3. Thread resume has been tested end-to-end. 4. Orphaned thread handling is implemented.

Section 2: Error Handling and Retry Logic

5. All tool nodes have retry logic with exponential backoff. Minimum implementation: 3 retries with exponential backoff (1s, 4s, 16s) and jitter.

6. LLM call failures have fallback behavior defined. 7. Tool output validation is implemented for every tool. 8. Maximum retry limits are enforced globally.

Section 3: Token Budget Management

9. Token budgets are set per node. 10. Long-running workflow state growth is bounded. 11. Token usage is monitored and alerted.

Section 4: Human Escalation Paths

12. Every automated decision has a human escalation path. 13. Human notification delivery is tested and confirmed. 14. Approval timeout handling is implemented. 15. Human override is logged to the audit trail.

Section 5: Monitoring and Observability

16. Structured logs are being generated for every node. 17. A production operations dashboard exists. 18. On-call alert routing is configured.

Section 6 & 7: Security and Rollback

19. All secrets are in Key Vault, not in environment variables or code. 20. The agent service principal has minimum required permissions. 21. Tool node inputs are validated against injection attacks. 22. A rollback plan exists and has been practiced. 23. The state schema migration strategy is defined.
