Validating messages

To ensure quality and completeness of your messages, you can use i18n-check.

This CLI helps you validate against issues like:

Missing translations in target locales
Inconsistent usage of ICU arguments across translations

Usage:

npx @lingual/i18n-check@latest --source en --locales messages

Output:

Found missing keys! ┌────────────────────┬───────────────────────────────┐ │ file │ key │ ├────────────────────┼───────────────────────────────┤ │ messages/de.json │ NewsArticle.title │ └────────────────────┴───────────────────────────────┘

💡

You can also use the --unused flag to detect keys that are defined in your messages, but are not referenced anywhere in your codebase (currently experimental).
