Static Module Dependency Graph

How to use Static Module Dependency Graph

Map supplied JavaScript modules, unresolved imports and dependency cycles locally. Provide a JSON filename-to-source map. The tool parses static import/export declarations, resolves exact relative virtual filenames, and reports cycles. Bare package names and unsupplied files remain unresolved; nothing is fetched.

1. Provide json object: relative filename → module source.
2. Choose the supported mode and run the tool. Review its assumptions and any reported errors.
3. Copy the result or download a separate output; reset to clear the current form.

Good to know

• 1–50 modules,200,000 aggregate input characters,50,000 per source and2,000 static edges. Explicit ECMAScript2022 only.
• Exact virtual paths only; no extension guessing, package resolution, dynamic-import resolution, filesystem reads or import fetching. Escaping the supplied virtual root is rejected.
• 10-second library startup and2-second isolated computation limit.
• Inputs are processed on this device and are not automatically saved or uploaded.
