typesafe-i18n is a fully type-safe, lightweight (~1kb) internationalization library for TypeScript and JavaScript projects. It generates boilerplate translation code, supports plural rules, switch-case statements, locale-dependent value formatting, async locale loading, and works in frontend, backend, and API projects.

Use cases

• add type-safe i18n to a TypeScript app
• translate UI strings with compile-time safety
• format dates and numbers per locale
• detect the user's locale in browser or server
• handle plural and gender-specific translations
• load translation locales asynchronously
• internationalize a Node.js backend or API

When to choose

• you want compile-time-checked translation keys and arguments
• bundle size matters and you need a tiny i18n runtime
• you use React, Vue, Svelte, Angular, Solid, or plain Node.js
• you need locale-aware formatting of dates, numbers, and plurals

When to avoid

• you need heavy ecosystem features like ICU message format tooling or translation management platform integrations
• your project is not JavaScript/TypeScript
• you rely on a framework's built-in i18n solution instead
