Platform localization

React localization that stays connected to product delivery.

ReRune adds OTA translation delivery to React through @rerune/react while existing components keep using i18next, react-i18next, useTranslation(), namespaces, interpolation, plurals, and bundled fallbacks.

Common challenge

Files and hooks handle runtime translation, but growing React teams still need shared status, review, terminology, and release coordination.

Best fit

React teams using i18next that want the public @rerune/react@1.0.0 SDK, OTA delivery, immediate bundled fallback, read-only browser credentials, and crawler-visible server rendering.

How ReRune helps

ReRune.setup(...) connects directly to the existing i18next instance instead of introducing a custom translation function, fetch interceptor, API base URL, or response decoder.

Workflow

From app copy to release-ready localization.

ReRune connects translation management to the delivery path developers already use: dashboard work, AI assistance, CLI/API sync, and OTA updates where a supported SDK is installed.

1

Install the SDK

Connect the supported app runtime to a ReRune publish ID while keeping native or framework localization behavior in place.

2

Publish approved text

Approve translation changes in the workspace, then publish runtime updates without turning every text fix into a full store release.

3

Refresh visible copy

Let supported SDK hooks check for updates and refresh text when new approved localization payloads are available.

4

Keep fallbacks intact

When runtime updates are unavailable, the app keeps reading bundled resources so localization failures do not break the product.

Coverage

App-first does not mean mobile-only.

Start where localization creates release friction, then keep web, mobile, and cross-platform products in one shared workspace as your surface area grows.

Developer delivery

Sync through the CLI. Publish through OTA SDKs.

Use the ReRune CLI locally or in CI/CD to manage project translations, then deliver approved runtime updates through the SDK built for your app.

Companion CLI

Install the ReRune CLI

Use the ReRune CLI to sync, validate, and manage translations right from your terminal. Run syncs in CI/CD or locally whenever you need to push a new language.

Homebrew (macOS/Linux):

brew install BasalBit/tap/rerune
  • Downloadable builds for macOS, Linux, and Windows
  • Uses the API keys you generate in the dashboard
  • Fits scripted CI/CD workflows through CLI and API access
rerune

Connect the project

Create the project config and connect the repository to its ReRune workspace.

rerune --pull

Pull approved updates

Bring current dashboard translations into the app or its build workflow.

rerune --push

Push local changes

Send local translation updates back to ReRune for the team to manage and publish.

React Web

Browser-native caching through @rerune/react, with ReRune.preload(...) for server-rendered and SEO-visible translations.

React Webi18nextOTA

Quick Start

@rerune/react@1.0.0

View on npm
npm install @rerune/react@1.0.0 i18next react-i18next

import {
  createReRuneBrowserCacheStore,
  ReRune,
} from '@rerune/react'

const cacheStore = createReRuneBrowserCacheStore()

One integration flow

Choose the platform package and cache adapter once. The rest of your localization setup and component usage stays aligned across web and native.

  1. 1

    i18next

    Keep your existing resources, namespaces, language switching, and fallback rules.

  2. 2

    ReRune.setup(...)

    Bind ReRune once with a publishable, read-only OTA ID and the platform cache.

  3. 3

    useTranslation()

    Render with normal react-i18next calls; remote values override only the keys they provide.

Shared i18next and ReRune setup

import i18next from 'i18next'
import { initReactI18next, useTranslation } from 'react-i18next'

const resources = {
  en: { translation: { headline: 'Bundled headline' } },
  de: { translation: { headline: 'Gebündelte Überschrift' } },
}

await i18next.use(initReactI18next).init({
  lng: 'en',
  fallbackLng: 'en',
  defaultNS: 'translation',
  resources,
  interpolation: { escapeValue: false },
})

export const reRuneClient = ReRune.setup({
  i18n: i18next,
  otaPublishId: '<READ_ONLY_OTA_PUBLISH_ID>',
  defaultLocale: 'en',
  bundledResources: resources,
  cacheStore,
})

export function Headline() {
  const { t } = useTranslation()
  return t('headline')
}

Questions

Questions teams ask before choosing a localization platform.

Does ReRune replace i18next or react-i18next?

No. @rerune/react integrates with the existing i18next instance. Components continue using useTranslation(), t(), namespaces, interpolation, plurals, fallbacks, and i18next.changeLanguage().

How do React SSR pages preload OTA translations?

Use ReRune.preload(...) before server rendering or generated SEO metadata, then hydrate the browser with initialHydrationState so crawler-visible content matches the OTA state.

Is the ReRune React SDK publicly available?

Yes. @rerune/react@1.0.0 is published on npm for React apps that use i18next and react-i18next.

One workspace

Start with one product workflow and expand from there.

Create projects, manage keys, use AI assistance with context, sync through CLI/API, and publish approved runtime updates when your app uses a supported ReRune SDK.
