workflow-compiler

The workflow compiler and runtime integrate with LangGraph by mapping compiled WorkflowSpecs into state graphs, enabling structured execution flow and state management. This architecture supports synchronous, streaming, and background execution modes.

To add new node types to the workflow runtime, you implement custom node executors and validate them through the compiler's specification layers. This process extends the state graph while maintaining execution flow and error handling.

The best way to debug workflow compilation and runtime issues is by leveraging the architecture overview and testing strategies, which cover validation layers, checkpoints, and node executor behaviors to isolate state management errors.

State management and checkpoints function by capturing the execution state across synchronous, streaming, and background modes within the runtime. This mechanism ensures reliable recovery and error handling across the end-to-end workflow.

Yes, the workflow runtime supports streaming and background execution modes alongside synchronous processing. These modes operate through the core runtime nodes and worker components to handle different execution requirements.

Testing strategies for workflow compiler integration should focus on validation layers, node executor behaviors, and integration points across the API, compiler, and worker. This ensures reliable production-grade workflows and state management.
