How we use Abstract Syntax Trees (ASTs) to turn Workflows code into visual diagrams

Cloudflare explained how it uses ASTs to statically analyze deployed Workflows code and generate visual diagrams in its dashboard.

The system fetches the code at deploy time, parses it, and traverses the AST to show step order, branching, and parallel execution.

This is useful because Workflows are code with dynamic control flow, so a diagram helps make execution structure easier to understand and debug.

Cloudflare says the approach should become even more valuable as AI-generated code and code reviews grow more common.
