Thank you so much, it worked for me, but I didn't understand anything :D

Kutsan Kaplan • Mar 22 '22

I implemented this to one of my own projects written in TypeScript, there is is some boilerplate you need to write but it works, even with dynamic routes, sitemap etc. Sure there is some code to adapt to your project but I think this is the way to go right now for next export. Only thing that I don't like this to have to create a second file per page, but I understand why this necessary and can't be avoided. Thanks again.

I think you should also add appWithTranslation github.com/adrai/next-language-det... section to initialize i18next, otherwise you're getting i18next is not initialized error.

Adriano Raiano • Mar 22 '22

That should already be covered with the default: github.com/isaachinman/next-i18nex...

@adrai Can you help me, why I'm getting a redirection in loop in production only?
I'm opening the site example.com. It redirects me with automatically detected language for example example.com/en. All ok, but if I reload the page, it redirects in loop and looks like something like this: example.com/en/en/en/en/en/en/en/en/...
But this problem in the production only. Locally it works without problems..
Help please..

Adriano Raiano • Jun 23 '23

if it is not reproducible locally, you may need to check on your prod system
if it is reproducible, please provide a minimal reproducible example repository

I have the same error! which is the solution?

gursidak_singh • Jul 25 '22

I need to create dynamic routes so created something like this in pages folder
pages/[locale]/gallery/[filter].tsx
In filter.tsx, I am catching the value of query.filter using useRouter hook. So after catching value of query i need to render some data from /en/common.json so i am trying to fetch it like
const data = t(gallery.metadata.${query.filter})
As in first render query.filter returns undefined so it gives error if i reload or directly loads on /gallery/rooms or /gallery/services page , but it works fine if i simply navigate to these routes using some next Link component.

II tried many solutions , but got some issue in all the solutions i tried to avoid it from accessing t('gallery.metadata.undefined')..

kindly help me in this, thanks in advance

gursidak_singh • Jul 25 '22

however it works fine if i am fetching data from some external url/source based upon value from query.filter

Adriano Raiano • Jul 26 '22

you may ask on stackoverflow with a more complete example

Raí B. Toffoletto • Feb 3 '22

Thanks a lot for this. You are a life saviour 🎉

Adriano Raiano • Feb 3 '22

You’re welcome…
If you want you can share this to the word 😉

I am writing project with typescript, and cannot use type "any".
I want to ask you about getStatic file.
Can you please tell the type of ctx?
And also ns by default is array of strings, but in makeStaticProps you assign to ns an empty object, should I change empty object to an empty array?

Adriano Raiano • May 27 '22

this is JavaScript, not TypeScript…
ns can be a string or an array of strings
ctx is coming from Next.js

Max Plotitsyn • May 27 '22

Made everything like in a tutorial, but now, when I try to run in development mode (also for build) I got this error:
error - ./node_modules/next-i18next/dist/commonjs/serverSideTranslations.js:78:0
Module not found: Can't resolve 'fs'
Can you help please how to resolve this issue

Adriano Raiano • May 27 '22

This seems to work: github.com/adrai/next-language-det...

provide a reproducible example and open a github issue

Filip Luśnia • Mar 2 '23 • Edited

I'm not sure about what causes the "fs" issue but it seems related to using getStaticProps in client components - move it to server component and pass the translation to the component which causes the error

Davi • Jun 1 '22

hey can you share some demo code of this setup, i also want to setup this in Ts
Thanks in advance

Max Plotitsyn • Jun 2 '22

I switched to next-translate, because it's easier, you just keep small json config file and locales folder and that's it, nothing more

Filip Luśnia • Mar 2 '23

is next-translate compatible with next export?

Romana Khatun • Apr 16 '22

Wow, this is great! Thanks a million!

Martin Krause • Dec 23 '21 • Edited

Interesting approach. I wrote about my experience with next export an i18n a few months back: next.js: i18n with static sites and created this easy to integrate npm-package: next-export-i18n.

As far as is see we took a different route for something similar. Great article!

Cheers!

Adriano Raiano • Dec 23 '21

interesting… did not know it…

I wanted to keep the i18next compatibility…

Nardos Tilahun • Jun 18

I followed the same step but for some reason.
const { t } = useTranslation("common");
is not loading the contents.
eg: {t("home1")} {t("home2")} would display home1 home2 in the page.

For context. I am using
"next": "12.3.0",
"next-i18next": "13.0.0",
"next-language-detector": "1.0.2",
How do I solve that?

Nardos Tilahun • Jun 19

Nvm I was missing.
export default appWithTranslation(MyApp)

Ivan Coene • Sep 18 '22

THANK YOU!!!!!
I've been searching for a solution for quite a while now!
Great idea!

Just added this snippet to my _app.js to make it even nicer instead of step 8

useEffect(() => {
     if (router.query.locale !== undefined ) {
       const qLng = typeof router.query.locale == 'string' ? router.query.locale : router.query.locale[0] 
       if (!i18nConfig.i18n.locales.includes(qLng)) {
          router.replace(`${language}/${qLng}`)
        }
      }
  }, [router.query.locale]);

Hi guys. I have just published a package for i18n next.js project SSG export, which called i18next-ssg.

With i18next-ssg, you could handle the i18n logic for next.js SSG easily.

Here is an example, if you have the pages defined like this:

After you run yarn build, the output files under the build folder will look like this:

/ will redirect to /[locale],/arya will redirect to /[locale]/arya, the locale value will be detected automaticaly.

This is the demo for this package: codesandbox.io/s/i18next-ssg-ozrpwx
This is the package github repo: github.com/Yrobot/i18next-ssg

Andry Orellana • Jan 20

Hi, thanks for taking the time to make this tutorial, I couldn't find a solution for this problem.
I am trying to implement it but I have problems with TS, I have not been able to create the Link component.
Any tutorial on this but using TS?

gursidak_singh • Jul 4 '22

How can i define dynamic routes, it gives error Id is not defined and also getStaticPaths is already occupied, please help on this urgently

Mohammed Irfan • Jul 18 '22

Hi, facing problem for [locale]/products/[productid].js
Here the productid will always be many, can be thousands, for that situation how can I handle it. Please share your knowledge on this, its urgent.

As with static path I had to pass a , but this situation I don't know which productid will be there.
Something like this:
params: { locale: lng, productid: product._id }

Adriano Raiano • Jul 18 '22

If you don’t know all information on build time, then SSG is probably not suitable for you.

Mohammed Irfan • Jul 18 '22

Is there no way on it.

TangoPJ • Jun 23 '23 • Edited

Hello, what did you mean in the 8th point of your code? If I understand you correctly - I should create an index.tsx file in the pages directory with the Redirect code? (in my case I have a single index.tsx page)
My structure looks like something like this:

Adriano Raiano • Jun 23 '23

i mean this: github.com/i18next/next-language-d...
or this: github.com/i18next/next-language-d...

zecka • Jun 5 '23

But with this approach is the language in url path is mandatory. You can not have empty path for default language, right ?

For example to have that:

example.com/my-page (default-language)
example.com/fr/my-page

or maybe the only way is to duplicate all your page like bellow:

pages/[locale]/[slug].js
pages/[slug].js

Any way to avoid duplicating pages ?

ted_dev • May 11 '22

Awesome! May I ask how can I use getStaticProps() to fetch data? Because it has been occupied in each pages. Thanks so much!

Adriano Raiano • May 11 '22

yes, just define your normal getStaticProps function and call github.com/adrai/next-language-det...

sarkis1997 • Dec 17 '22 • Edited

Do you have an example of this? Currently I have underneath code, but I can't figure out how to use getStaticProps() to fetch data in addition to the makeStatisProps function.

import { getStaticPaths, makeStaticProps } from "../../lib/get-static";
export { getStaticPaths };

export async function getStaticProps() {
const { data: headerFooterData } = await axios.get(HEADER_FOOTER_ENDPOINT);

makeStaticProps();
return {
props: {
headerFooter: headerFooterData?.data ?? {},
},
revalidate: 1,
};
}

Seems your server returns a 508 error 🤷‍♂️

ted_dev • May 12 '22

Hello,
The only issue with this solution is that next router doesn't take into account the locale, so I had to override it as follow to add the locale when calling "push":

import {useRouter as _useRouter} from "next/router";
import i18nConfig from '../../next-i18next.config';
import {UrlObject} from "url";
declare type Url = UrlObject | string;
interface TransitionOptions {
  shallow?: boolean;
  locale?: string | false;
  scroll?: boolean;
}

export const useRouter = () => {
  const router = _useRouter();
  const locale = router.query.locale as string || '';
  if (!router.locale && locale)
    router.locale = locale;
  if (!router.defaultLocale && i18nConfig.i18n.defaultLocale)
    router.defaultLocale = i18nConfig.i18n.defaultLocale;
  if (!router.locales && i18nConfig.i18n.locales)
    router.locales = i18nConfig.i18n.locales;
  const oldPush = router.push;
  //we override the push method to add the current locale
  router.push = (url: Url, as?: Url, options?: TransitionOptions): Promise<boolean> => {
      if (typeof url == "string" && !url.startsWith(`/${locale}`))
        url = `/${locale}${url}`;
      else if (typeof url === 'object' && url.pathname && !url.pathname.startsWith(`/${locale}`))
        url.pathname = `/${locale}${url.pathname}`;
    return oldPush.apply(this, [url, as, options]);
  }
  return router;
}

Anyone came with a better solution ? It seems a bit of a hack!

Arkady Magomedov • Jul 29 '22

I use strapi with nextjs. I simply run LOCALE=xxx yarn build && yarn export -o out/xxx for each locale that I need to support.

For i18n enabled routing an nginx proxy can be used together with custom cookies and/or browser language settings

Kutsan Kaplan • Mar 22 '22

Thanks a lot! But is there a way to keep current selected language something like in localStorage so that users don't have to select locale every time they visit my website?

Adriano Raiano • Mar 22 '22

yes, by calling languageDetector.cache(locale) like in point 12

Kutsan Kaplan • Mar 22 '22

I'm sorry, I must have missed that part. Thanks again!
