# `deslop/unused-export`

Flag a named or default value export (isTypeOnly=false) that no other module in the project imports.

- **Category:** Dead Code
- **Severity:** warn
- **Source:** deslop-js
- **Framework:** global
- **Enabled when:** react-doctor deadCode analysis enabled (default true); whole-project scan only — skipped in --diff/--staged modes
- **Documentation:** <https://github.com/millionco/deslop-js>

## Validation prompt

Use this to decide whether a fired diagnostic is real or a false positive.

Fires from deslop's detectDeadExports: a value export (UnusedExport with isTypeOnly=false) whose `path::name` key never appears in the cross-module usage map built from every import and re-export edge in the project, and whose name isn't referenced locally or linked as the default export — so no other tracked module imports it. The finding is bare (only path, name, line, column); there is no reason, trace, or confidence to lean on, so confirm only after you yourself grep the repo and find zero importers. False positive: a public package API surface (an export named in package.json exports/main/bin, or a library entry like src/index.ts re-exporting it) that deslop's entry detection missed and thus did not treat as an entry point; a symbol consumed by an external or untracked consumer (a plugin/registry loaded by string, a test-only or generated importer outside the scanned graph); or one reached only through an `export *` star re-export the linker could not resolve (note the "re-export propagation skipped" failure mode) — suppress these, the export is intentionally reachable.

## Fix prompt

Use this once validation confirms the diagnostic is real.

Confirm no importer exists across the repo, then drop the `export` keyword so the symbol becomes module-private: `export function helper()` becomes `function helper()`; if nothing in the file uses it either, delete the declaration outright. If it was only re-exported through a barrel, remove its line from the barrel too. When it is genuinely public API, leave it and instead make deslop see the entry — add the file to your package.json exports/main or an index entry so it counts as an entry point rather than dead code.
