Use Case

Type-safe i18n for TypeScript

Auto-generated TypeScript definitions for every translation key. Full IDE autocomplete, compile-time validation, and zero missing keys in production.

i1n.d.ts

// Auto-generated by i1n pull
export const common = {
  greeting: "common.greeting",
  errors: {
    not_found: "common.errors.not_found",
    unauthorized: "common.errors.unauthorized",
  },
} as const

// Usage — full autocomplete, compile-time safety
import { t } from 'i1n'
t('common.greeting')       // ✓ valid
t('common.typo')           // ✗ TypeScript error

How i1n solves this

Auto-generated types

Every i1n pull generates i1n.d.ts from your translation files. No manual type maintenance required.

Full IDE autocomplete

Your IDE autocompletes every translation key. Nested keys, namespaces, and interpolation variables are all typed.

Compile-time validation

Reference a key that does not exist? TypeScript catches it before your code runs. No more missing translations in production.

Framework-agnostic

Works with React, Vue, Svelte, Next.js, and any TypeScript project. The generated types adapt to your translation structure.
