I migrated to next.js and started to use next-i18next. I would like to know, how to make next-i18next load locales from the public folder? It works only when I place the locales folder in the root directory not in public.
i18n.json ;
{
"locales": ["en", "fr", "ar"],
"defaultLocale": "en",
"pages": {
"*": ["common"]
}
}
next.config.js ;
// next.config.js
const nextTranslate = require("next-translate");
module.exports = {
...nextTranslate(),
};
Create i18n.js file root add this code inside:
const path = require('path');
module.exports = {
i18n: {
locales: ['en', 'ru', 'tm'],
defaultLocale: 'en',
localeDetection: false,
localePath: path.resolve('./public/locales'),
},
};
and add config next.config.js file this:
const { i18n } = require('./i18n');
const nextConfig = {
reactStrictMode: true,
i18n,
};
module.exports = nextConfig;
after every page add transalition code. example: index.file
import React, { useContext, useEffect } from 'react';
import { serverSideTranslations } from 'next-i18next/serverSideTranslations';
import { useTranslation } from 'next-i18next';
import Router from 'next/router';
import { Title } from '../components';
import i18n from '../i18n';
const Home = () => {
const { t } = useTranslation('');
useEffect(() => {
if (!user) {
Router.push('/login');
}
});
return (
<>
<Title title={`${t('page.home')} | Trillo`} />
<div className="min-h-screen">Home</div>
</>
);
};
export const getServerSideProps = async ({ locale }) => (
{ props: {
...(await serverSideTranslations(
locale,
['common'],
i18n,
)),
} }
);
export default Home;
After you create these files inside public folder like this. see this and see this 2

i created i18n.json
i18n.json
{
"locales": ["en-US", "tr-TR"],
"defaultLocale": "tr-TR",
"defaultNS": "common",
"pages": {
"*": ["common"]
}
}
i want to get locales ["en-US", "tr-TR"] values in _middleware.tsx
i created _middleware.tsx and
I have read the directions in this document
https://nextjs.org/docs/api-reference/next/server#nextrequest
nextUrl includes i18n
so i want to reach locales in i18n object but I get undefined value.
import { NextResponse, NextRequest } from "next/server";
export async function middleware(req: NextRequest) {
const { i18n } = req.nextUrl;
const { locales } = i18n;
console.log(locales);
return NextResponse.next();
}
How can I get the available locales values?
I'm not quite sure why you need middleware for this case, you can get all locales from the SSR props, but you need to configure
First, you need to define your locales in next-18next.config.js
module.exports = {
i18n: {
defaultLocale: "de",
locales: ["de", "en"],
},
};
Then in next page get all locales with SSR Props
export const getServerSideProps: GetServerSideProps = async ({ locales }) => {
console.log(locales) // You should get an array of all locales
}
For now, best way to do this is importing next-i18next.config.js manually.
next-i18next.config.js
module.exports = {
i18n: {
defaultLocale: "en",
locales: ["en", "tr"],
localeDetection: false,
},
};
middleware.js
import { i18n } from "./next-i18next.config.js";
export function middleware(req) {
const availableLocales = i18n.locales;
}
You can import your i18n.json to achieve same.
I have a website in NextJS with next-i18next, and every page must be translated except for the legal pages.
These legal pages are in markdown, and I have dynamic routing enabled thanks to a [legal].js page and the getStaticPaths and getStaticProps in it.
The problem is that by building my website, my legal pages are prefixed with the language (here en). I would like to remove it as I don't want these pages to be translated.
What am I doing wrong here?
Thanks a lot 🙏
Folder structure:
pages
|- index.js
|- [legal].js
|- privacy-policy.mdx
next-i18next.config.js
module.exports = {
i18n: {
defaultLocale: 'en',
locales: ['en'],
fallbackLng: 'en',
defaultNS: ['homepage', 'header', 'footer'],
localeDetection: false,
},
}
[legal].js
import matter from 'gray-matter'
import ReactMarkdown from 'react-markdown'
import { serverSideTranslations } from 'next-i18next/serverSideTranslations'
import glob from 'glob'
const LegalPage = ({ markdownBody }) => (
<ReactMarkdown>{markdownBody}</ReactMarkdown>
)
export async function getStaticProps({ locale, params }) {
const { legal } = params
const content = await import(`./${legal}.mdx`)
const data = matter(content.default)
return {
props: {
...(await serverSideTranslations(locale, ['header', 'footer'])),
markdownBody: data.content,
},
}
}
export async function getStaticPaths() {
const blogs = glob.sync('src/pages/**/*.mdx')
const blogSlugs = blogs.map(file => {
const parts = file.split('/')
return parts[parts.length - 1].replace('.mdx', '')
})
const paths = blogSlugs.map(slug => ({
params: { legal: slug },
}))
return {
paths,
fallback: false,
}
}
export default LegalPage
build output:
All static HTML files should be created in separate folders for each locale.
Your default locale can be omitted in the URL, and the following URLs are equivalent:
example.com/my-first-blog
example.com/en/my-first-blog
🎈 As a solution, you can setup app i18n base on domain:
module.exports = {
i18n: {
locales: ['en'],
defaultLocale: 'en',
domains: [
{
domain: 'example.com',
defaultLocale: 'en',
},
]
}
}
I'm using next-i18next module for multilingual support.
I have some static pages and dynamic pages as well. both working fine on local.
I deployed all static pages on vercel, all worked fine on vercel. But dynamic page is not working on vercel. it shows 404 page for that dynamic page.
Below is the code of the dynamic page. (pages/test-page/[questionId].js)
import { useState, useEffect } from "react";
import {Layout} from "#components/common";
import { useRouter } from 'next/router';
import { useTranslation } from 'next-i18next'
import { serverSideTranslations } from 'next-i18next/serverSideTranslations'
import { TestComponent } from '#components/TestComponent'
const TestPage = () =>
{
const { t } = useTranslation('common')
const router = useRouter()
const {questionId} = router.query;
const [isApiLoaded,setIsApiLoaded] = useState(false)
return (
<TestComponent
t={t}
isApiLoaded={isApiLoaded}
setIsApiLoaded={setIsApiLoaded}
/>
)
}
TestPage.Layout = Layout
export const getServerSideProps = async ({ locale }) => ({
props: {
...(await serverSideTranslations(locale, ['home', 'common']))
}
});
export default TestPage;
How to fix this issue?
Adding localePath in next-i18next.config.js did help in my case.
const path = require('path')
module.exports = {
i18n: {
defaultLocale: 'en',
locales: ['en', 'de'],
localePath: path.resolve('./public/locales')
}
};
I was facing the same issue and for a temporary fix I used the i18n object from next-i18next that has a function called getResource that gets the current locale with its translations
// import { i18n } from 'next-i18next';
// import { useRouter } from 'next/router';
const [translation, setTranslation] = useState({});
useEffect(() => {
const bundle = i18n.getResource(locale, 'common');
setTranslation(bundle);
}, []);
And to avoid rewrite the code with the t function, you could use
// LINK https://stackoverflow.com/a/43849204/14263138
const t = (word) => word
.split('.')
.reduce((p, c) => (p && p[c]) || null, translation);
With this applied, you don't need to use the getServerSideProps
Although the post is now old, I share the solution that solved the problem in my project (focus on the addition of localePath):
const path = require('path');
module.exports = {
i18n: {
defaultLocale: 'en',
locales: ['en', 'it', 'de', 'es', 'fr', 'ja']
},
defaultNs: 'shared',
fallbackLng: { default: ['en', 'it', 'de', 'es', 'fr', 'ja'] },
localePath: path.resolve('./public/locales'),
};
I specify that localePath should not be included among the properties of i18n as indicated in another answer as doing so produces a type error.
Also make sure to use getServerSideProps and not getStaticProps on pages, for example:
export async function getServerSideProps({ locale }) {
return {
props: {
...(await ssrTranslations(locale, ['login', 'shared'])),
},
};
}
Import the serverSideTranslations
import { serverSideTranslations } from "next-i18next/serverSideTranslations";
Now from the getServerSideProps, pass the ..(await serverSideTranslations(locale, ["common"])), with the props.
export const getServerSideProps: GetStaticProps = async ({
locale,
locales,
query
}: any) => {
return {
props: {
...(await serverSideTranslations(locale, ["common"])),
}
}
};
Now add your language strings inside
/public/locales/en/common.json
For example
{
"home": {
"Test": "Test"
}
}
You can add more language strings inside the locales directory.
Restart your Next.js app. It will work.
Next translation is displaying key instead of lang
common:menu.1.title common:read_more
i18n.js
module.exports = {
locales: ['en', 'de', 'cs'],
defaultLocale: 'en',
redirectToDefaultLang: true,
pages: {
'*': ['common'],
'/404': ['home'],
'/': ['home'],
'/about': ['about'],
},
interpolation: {
prefix: '${',
suffix: '}',
},
logger: true,
logBuild: true,
loadLocaleFrom: (locale, namespace) =>
import(`./public/locales/${locale}/${namespace}`).then((m) => m.default),
}
this is my next.config.js
const nextTranslate = require('next-translate')
module.exports = nextTranslate()
_app.js
import I18nProvider from 'next-translate/I18nProvider';
class MyApp extends App {
render () {
const { Component, pageProps, store } = this.props
return (
<I18nProvider lang={'en'} >
<Component {...pageProps} />
<GoTop scrollStepInPx="50" delayInMs="16.66" />
</I18nProvider>
);
}
}
export default MyApp
and following HOC
import React, {Component} from "react";
import withTranslation from 'next-translate/withTranslation'
class NavBarLink extends Component {
render() {
const { t, lang } = this.props.i18n
const description = t('menu.1.title')
const description2 = t('read_more')
return <p>{description + ' '+ description2}</p>
}
}
export default withTranslation(NavBarLink, 'common')
The return value is common:menu.1.title common:read_more
Please can someone tell me what is missing in my code?
In new version of next-translate wouldn't need to provide I18nProvider as said here.
But when you provider that you should provide all namespaces you wanna use.
You'd better to look at this migration guide.
I tried to find a way to change the language by changing the site's sub-path in the next-i18next package, I searched the Internet (https://github.com/isaachinman/next-i18next/issues/32 , https://github.com/i18next/i18next-browser-languageDetector#detector-options) for an answer to this question, but it did not work. After changing the subpath in the url it is duplicated and redirects me to a page that does not exist.
my code:
// path-to-my-project/i18n.js
const NextI18Next = require('next-i18next').default;
const i18nextBrowserLanguageDetector = require('i18next-browser-languagedetector').default;
const { localeSubpaths } = require('next/config').default().publicRuntimeConfig;
const path = require('path');
module.exports = new NextI18Next({
otherLanguages: ['ru'],
defaultNS: 'common',
localeSubpaths,
localePath: path.resolve('./public/static/locales'),
use: [i18nextBrowserLanguageDetector],
});
// path-to-my-project/pages/_app.js
import '../styles/main.scss';
import NProgress from 'nprogress';
import 'nprogress/nprogress.css';
import Router from 'next/router';
import App from 'next/app';
import { appWithTranslation } from '../i18n';
Router.events.on('routeChangeStart', () => NProgress.start());
Router.events.on('routeChangeComplete', () => NProgress.done());
Router.events.on('routeChangeError', () => NProgress.done());
const MyApp = ({ Component, pageProps }) => (
<Component {...pageProps} />
);
MyApp.getInitialProps = async (appContext) => ({ ...await App.getInitialProps(appContext) });
export default appWithTranslation(MyApp);
maybe I just missed something, because it's my first project on next.js, so I'm asking for help in the community and would be grateful for any help or hint.
By default next-i18next will try to detect the language to show from users browser.
Try to disable it.
const NextI18Next = require('next-i18next').default
const { localeSubpaths } = require('next/config').default().publicRuntimeConfig
const path = require('path')
module.exports = new NextI18Next({
browserLanguageDetection: false, // <---
serverLanguageDetection: false, // <---
otherLanguages: ['de'],
localeSubpaths,
localePath: path.resolve('./public/static/locales')
})
in file next.config.js i have this settings:
// path/to/project/next.config.js
const { nextI18NextRewrites } = require('next-i18next/rewrites');
const localeSubpaths = {
ru: 'ru',
};
module.exports = {
rewrites: async () => nextI18NextRewrites(localeSubpaths),
publicRuntimeConfig: {
localeSubpaths,
},
devIndicators: {
autoPrerender: false,
},
};
but there was not enough configuration for English localization, so you just need to add it:
// path/to/project/next.config.js
const { nextI18NextRewrites } = require('next-i18next/rewrites');
const localeSubpaths = {
en: 'en', // <------
ru: 'ru',
};
module.exports = {
rewrites: async () => nextI18NextRewrites(localeSubpaths),
publicRuntimeConfig: {
localeSubpaths,
},
devIndicators: {
autoPrerender: false,
},
};
