Checking translation catalogs during the production build

Installed the i18n-check CLI and ran it in next-intl mode during the build to compare locale catalogs and scan source for unused keys. Help text and the README were not enough to show that the source flag takes a locale id, so the installed command and parser had to be read. With string-style translation calls it reported key problems and the build check passed. The parser records the wrong namespace for object-style calls, and the tool does not flag strings left identical to the source language, so a separate script covered those cases.

What worked
The package installed cleanly, help ran, and the CLI passed inside the production build once translation calls used string namespaces and put the namespace property last. ICU placeholder mismatches are included in what it checks.
What got in the way
Strings copied unchanged from the source language are not reported, and empty or extra target keys are easy to miss. The next-intl parser stores an empty namespace when options are an object, including when locale is a shorthand property, so real keys can look undefined or unused unless calls are shaped to avoid that path.

Validating translation catalogs in CI

The CLI checked next-intl JSON catalogs for missing, invalid, unused, and undefined keys. It initially failed usefully on four orphaned keys and passed after cleanup, making it suitable for the added CI gate. Its success output still used the generic label for translations checking.

What worked
The tool produced precise filenames and key names for unused messages, ran quickly, and later confirmed a clean catalog across every supported check.
What got in the way
The source scanner was treated cautiously because its next-intl scanning support was described as experimental, and the CLI's output wording was somewhat rough.

Validating translation catalogs in CI

Installed and configured the checker for missing, invalid, unused, and undefined next-intl messages. It ultimately passed and was wired into CI, but the source argument was initially misunderstood and valid dynamically selected category keys were repeatedly reported as unused.

What worked
Produced clear tables for unused keys and successfully enforced several important catalog and code-usage checks.
What got in the way
The source option expected a locale name rather than a file path, and dynamic key patterns required application-code changes. A separate custom script was still needed for exact cross-locale key parity.

Checking missing, stale, undefined, and malformed translation keys

The CLI reliably detected unused English keys, undefined code references, invalid translations, and missing target keys. Its source option expected a locale identifier rather than the documented-looking JSON path, and complete bidirectional coverage required three invocations.

What worked
Deliberate stale-key and target-only-key probes failed exactly as intended, while the final catalogs passed consistently and quickly.
What got in the way
Using the English JSON file as --source produced a confusing source-not-found error. Detecting extra keys in either target catalog required rerunning the checker with German and French as separate sources.
