@localeguard/core

Core localization checks for LocaleGuard — the engine behind the localeguard CLI. Zero runtime dependencies.

Provides:

• A JSON parser that reports duplicate keys and syntax errors with line numbers
• Key flattening and source-vs-target key comparison
• Interpolation validation for {{double-brace}} (i18next) and {single-brace} (ICU / react-intl), with ICU plural/select handled conservatively
• Text and JSON reporters

Most users should install the localeguard CLI rather than this package directly.

import { runCheck, formatText } from "@localeguard/core";

const result = runCheck(
  { sourceLocale: "en", locales: ["fr"], localesPath: "public/locales" },
  { rootDir: process.cwd() },
);
console.log(formatText(result, { color: true }));
process.exitCode = result.stats.failed ? 1 : 0;
