v2.0.0

Date: 2025-10-30

Version: v2.0.0

We’re introducing server‑side HMR for translation files in development. When a JSON translation changes, the server cache invalidates only the affected keys, and subsequent requests immediately receive fresh data—no restarts required.

What’s New?

• Server‑side HMR for translation files
• Instant cache invalidation per page/locale
• Seamless DX while editing content

How it works

• Watcher in src/runtime/server/plugins/watcher.dev.ts observes <rootDir>/<translationDir>/**/*.json
• Page files (e.g., pages/<page>/<locale>.json) invalidate _locales:merged:<page>:<locale>
• Root-level files (e.g., <locale>.json) invalidate all merged keys for that locale
• Auto‑registered from src/module.ts in dev when experimental.hmr !== false

Configuration

export default defineNuxtConfig({
  i18n: {
    experimental: { hmr: true }, // default in dev
  },
})
