translify check-duplicates

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

Detects two distinct problems in your translation files:

• Duplicate values — multiple keys sharing the same translated string.
• Duplicate keys — the same key declared more than once inside a single JSON file. JSON.parse silently keeps only the last occurrence, so this is invisible once the file is loaded — this check scans the raw file text instead.

Usage

translify check-duplicates
translify check-duplicates --output report.json

Example output

⚠ Found 1 duplicate key (silently overwritten by JSON.parse)

▸ Duplicate keys

  messages/en.json
    ✗ CommonMessage.pleaseLogin declared at:
      line 42, column 5
      line 118, column 5

⚠ Found 2 duplicate values

▸ Duplicate values

  [en] "Submit"
    · forms.submit
    · buttons.primary.submit
    · actions.send

  [en] "Cancel"
    · forms.cancel
    · dialog.cancel

When to act

Duplicate values aren't always a problem. Sometimes "Submit" and "Send" really should be the same string in your language. But duplicates can also indicate:

• Keys that were created twice by different team members
• Opportunities to consolidate into a shared key (e.g. common.submit)

Duplicate keys, on the other hand, are always worth fixing — one of the two values is silently lost.
