Internationalization plugin for Vue.js

Last verified Sep 9, 2026 against vue-i18n@11.4.10.

vue-i18n publishes both a CommonJS entry and a native ESM entry (ESM added in 9.2.0). require("vue-i18n") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 22. import "vue-i18n" works alongside it.

## What to do

1. Nothing to change. require("vue-i18n") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 22. import * as vueI18n from "vue-i18n" works alongside it; use named imports for what the ESM entry exports.
2. TypeScript: types are bundled; install nothing extra.
