i18n-sharpenAST-based Static Analysis for Localization

Keep your translation keys clean, synchronized, and type-safe — with the accuracy of a compiler, not a grep.

AST-Based Parsing

Scans codebases using real compilers (TS, Vue, Svelte, Astro) to understand dynamic structures, template literals, and directives.

Automatically detects raw hardcoded strings in HTML text nodes or attributes and checks them against configurable ignore lists.

Cleans up unused keys safely. Supports a command-line TUI picker to let you select which keys to keep or discard.

Generates beautiful coverage and quality reports (i18n-coverage.md) that integrate perfectly into your PR comments.

Protects against file corruption via atomic write-then-rename and prevents prototype pollution attacks.

Lazy-loads framework compilers dynamically. Extremely lightweight package with zero bundled bloat.
