Use when internationalizing a frontend project — sets up i18next + react-i18next (React) or vue-i18n (Vue) with typed message keys, lazy-loaded per-locale catalogs, Intl-based number/date/relative formatting, and a persisted locale choice detected from the browser.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Set Up i18n

## 1. Audit current state

```bash
cat .claude/stack-profile.md 2>/dev/null || cat ~/.claude/stack-profile.md 2>/dev/null   # frontend.framework, frontend.meta, package_manager
grep -E '"(i18next|react-i18next|vue-i18n)"' package.json 2>/dev/null
ls src/locales 2>/dev/null
grep -rn ">[A-Z][a-z]\+ [a-z]" src/components 2>/dev/null | head   # hardcoded UI strings (rough)
```

Read `frontend.framework` (react → i18next, vue → vue-i18n) and `frontend.meta`: `nuxt` → `@nuxtjs/i18n`, `next` → `next-intl` or the framework's routing i18n; this skill is the Vite-SPA path. Commands use pnpm; translate for `package_manager`. **Prerequisite:** `@/` alias. The locale switcher is UI state (per `set-up-state-management`).

## 2. Decide what to do
- No i18n → full setup.
- Library present, strings still hardcoded → extract to catalogs (step 5) + type the keys (step 7).
- Set up, no lazy loading → split catalogs per locale (step 6).

## 3. Detect framework
React → **i18next** + **react-i18next**. Vue → **vue-i18n** (Composition API). Both format with the **`Intl`** APIs. Why these libraries: `i18n-patterns.md`.

## 4. Install

### React
```bash
pnpm add i18next react-i18next
```

How to install

The exact contents, by fingerprint
mdr add velimirmueller/lab-claude-skills/set-up-i18n@sha256:aa88dc843479600f

The line at the top of this page pins the label git:20261009.0ae007b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
