Action Summary

Fallow is a static analysis tool for TypeScript and JavaScript codebases that identifies and helps eliminate unused code, duplication, complexity, and architectural issues, with optional runtime insights for production behavior. It automates the process of analyzing code health, enabling developers to clean up their codebases, enforce best practices, and review changes more efficiently. With its zero-configuration setup and sub-second performance, Fallow provides a comprehensive, project-wide view of code quality without requiring a Node.js runtime.

What’s Changed

Highlights

  • includeEntryExports is now a config option, and --include-entry-exports is a global CLI flag. Persistently opt in to entry-file export validation via "includeEntryExports": true in your fallow config, or pass the flag once on combined mode (fallow --include-entry-exports). Previously the bare combined invocation rejected the flag because it was only defined on the dead-code subcommand.
  • SCSS / Sass @use 'X' no longer resolves to a sibling X.tsx. Stylesheet importers now reject standard-resolver hits on JS/TS-family extensions and route through SCSS-aware fallbacks instead, eliminating phantom circular dependencies in standard CSS-modules / Angular styleUrls patterns.

Added

  • includeEntryExports config option. Set "includeEntryExports": true (JSON / JSONC) or includeEntryExports = true (TOML) in your fallow config. The CLI flag ORs with the config value when set.
  • --include-entry-exports is now a global flag. Accepted on combined mode (fallow --include-entry-exports), fallow dead-code, fallow audit, and fallow watch (with the override applied at every config reload).
  • include_entry_exports MCP param on the audit tool. Sibling-tool parity with analyze and check_changed. Forwards --include-entry-exports to the dead-code sub-pass.
  • Stable-API listings updated. --include-entry-exports and includeEntryExports are now part of docs/backwards-compatibility.md and follow the project’s semver guarantees.

Thanks @filipw01 for the report. (Closes #249)

Fixed

  • SCSS / Sass @use 'X' no longer resolves to a sibling X.tsx. When both Widget.scss and Widget.tsx exist next to each other and a .scss importer does @use 'Widget', fallow now resolves the import to Widget.scss per Sass’s actual resolution algorithm. Stylesheet importers now reject any standard-resolver hit whose extension is a JS/TS-family extension (.tsx, .ts, .mts, .cts, .js, .jsx, .mjs, .cjs) and re-route through the SCSS-aware fallback chain (CSS-extension probe, _filename partial convention, framework include paths, node_modules walk-up). When those also fail, the import is reported as unresolved instead of falling through to JS/TS extensions. This eliminates phantom 3-file circular dependencies in standard CSS-modules / Angular styleUrls patterns where the .tsx component imports its own .scss and a sibling .scss shares variables/mixins via @use. Thanks @OmerGronich for the precise reproduction and the suggested fix. (Closes #245)
