translify check-unused

Formerly translify unused — the old name still works but is deprecated.

Detect translation keys that are defined in your JSON files but never referenced in source code.

Usage

translify check-unused
translify check-unused --verbose
translify check-unused --output report.json

Example output

⚠ Found 5 unused keys

▸ Unused keys

  messages/en.json [en]
    ⚠ old.navbar.home          "Home"
    ⚠ deprecated.footer.link   "Privacy Policy"

  messages/fr.json [fr]
    ⚠ old.navbar.home          "Accueil"

Options

Option	Description
--output <file>	Write the report to a file (.json or plain text)

Exit code

• 0 — no unused keys found
• 1 — unused keys found

Notes

Unused keys do not always mean they should be deleted. Some keys may be:

• Used dynamically: t(\${key}`)` — Translify can't detect these statically
• Used in a part of your codebase not covered by source.include
• Intentionally kept for future use

Always review before removing.
