Explicitly add config (possible too to create a file in ./lib/i18n`)

import React from "react";
import { appWithTranslation } from "next-i18next";
import { Layout } from "../components/layout";
import nextI18nConfig from '../next-i18next.config';

Import from our own getServerSideTranslation to load the config

react: {
useSuspense: false,
},
localePath: typeof window === "undefined" ?

The localePath for monorepos.

The typeof window:

A defensive way. Now that next-i18next config is imported in a client side page (_app.tsx), I'm not sure I would rely on webpack/nextjs to ensure it's dropped. I've been hit few times on older nextjs versions (next-i18next supports next > 10)

But what I'm not sure

  • Is localePath used/interpreted by i18next on the client side ? or only on server side ? (I mean by default)

both:

here on server side: https://github.com/i18next/next-i18next/blob/master/src/config/createConfig.ts#L128 (for i18next-fs-backend)
here on client side: https://github.com/i18next/next-i18next/blob/master/src/config/createConfig.ts#L194 (for backends used via use option, for example i18next-http-backend etc... here an example)

Great ! So actually it seems it makes sense to test typeof window...

Seems confirmed by i18next/next-i18next#1552 (comment)
