# sfn-diagram

> Generate SVG, Mermaid, HTML, and PNG diagrams from AWS Step Functions ASL (Amazon States Language) definitions, CloudFormation/SAM/CDK templates, or live AWS state machines. Runs in Node, the browser, and edge runtimes.

Core (`sfn-diagram`) is platform-agnostic. Only `sfn-diagram/png` and the CLI are Node-only.
Four entry points: `sfn-diagram` (SVG/Mermaid/HTML), `sfn-diagram/png`, `sfn-diagram/aws`, `sfn-diagram/cfn`.
