Use Case

Type-safe i18n that your compiler enforces.

i1n pull generates i1n.d.ts with const assertions for every key. Your IDE autocompletes, your compiler catches missing translations, your deploys never break.

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 i1n.d.ts

Every i1n pull generates a TypeScript definition file with const assertions. Keys are typed, namespaces are structured, autocomplete just works.

Compile-time validation

If a key doesn't exist in your translations, TypeScript errors at compile time. Missing translations never reach production.

Works with any framework

The generated types work in React, Next.js, Vue, Svelte, and any TypeScript project. No framework lock-in.

Namespace-aware

Types are generated per namespace. Import only the keys your component needs for optimal tree-shaking.
