# Internationalization (https://s3.dimah.dev/docs/i18n) English needs no setup. To localize, put a map in a file and pass it to the provider. ```ts title="lib/translations-fa.ts" import type { Translations } from "@dimah-s3/react"; export const fa = { "Upload failed(toast)": "آپلود ناموفق بود", "Cancel(dialog button)": "لغو", } satisfies Partial; ``` ```ts title="lib/s3-client.ts" "use client"; import { createS3Client } from "@dimah-s3/react"; export const s3Client = createS3Client(); export const S3Provider = s3Client.Provider; ``` ```tsx title="app/layout.tsx" import { S3Provider } from "@/lib/s3-client"; import { fa } from "@/lib/translations-fa"; export default function RootLayout({ children, }: { children: React.ReactNode; }) { return ( {children} ); } ``` Vite / other all-client apps can pass `translations` on `` instead. Missing keys stay English. ## API errors [#api-errors] The server always responds in English. With `@dimah-s3/ui` or the React hooks you do not need anything else — the same `translations` map localizes those messages.
