Creating a VueI18n instance

In a file app.js, define your Vue application.

require("web.dom_ready");

if (!$("#my_app_node").length) {
  return $.Deferred().reject("DOM doesn't contain '#my_app_node'");
}

const i18nFactory = require("vue_i18n.i18nFactory");
i18nFactory.setLang("fr_FR")

const i18n = i18nFactory.makeI18n();
const app = new Vue({i18n}).$mount('#my_app_node');

Inside other javascript files, you may register your messages:

const i18nFactory = require("vue_i18n.i18nFactory");
i18nFactory.addMessages(
    {
        en: {
            foo: "bar",
        },
        fr_FR: {
            foo: "baz",
        },
    }
)
