Dead Exports

Exported functions that nothing imports

infoAI Qualitydead-exports

Why this matters

AI tools export everything by default. Over time, dead exports accumulate — increasing bundle size, confusing developers, and making it unclear what the public API actually is.

✗ Bad

// lib/utils.ts
export function formatDate(d: Date) { ... }
export function formatTime(d: Date) { ... }  // Nothing imports this
export function formatDateTime(d: Date) { ... }  // Nothing imports this
export function capitalize(s: string) { ... }  // Nothing imports this

✓ Good

// lib/utils.ts
export function formatDate(d: Date) { ... }

// Remove or keep as non-exported if unused:
function formatTime(d: Date) { ... }

How to fix

Search for each export's usage across the project. Remove the export keyword from functions that are only used locally. Delete functions that aren't used at all.
