Argument of type 'string' is not assignable to parameter of type 'never'.ts(2345)

[nicitaacom]

I want to change language from 'en' to 'fr'

I use this guide

I expect that in this guide I can just ctrl+c ctrl+v and it will work with next.js 14

In fact I get this error Argument of type 'string' is not assignable to parameter of type 'never'.ts(2345)

Code I use to get error app/[locale]/client/page.tsx

'use client'

import { useI18n, useScopedI18n } from '../../locales/client'
import { useChangeLocale, useCurrentLocale } from '../../locales/client'

export function ClientPage () {

 const t = useI18n()
  const scopedT = useScopedI18n('hello')
   const changeLocale = useChangeLocale()
  const locale = useCurrentLocale()
  return (
    <div>
      <p>{t('hello')}</p>

      {/* Both are equivalent: */}
      <p>{t('hello.world')}</p>
      <p>{scopedT('world')}</p>

      <p>{t('welcome', { name: 'John' })}</p>
      <p>{t('welcome', { name: <strong>John</strong> })}</p>
       <>
      <p>Current locale: {locale}</p>
      <button onClick={() => changeLocale('en')}>English</button>
      <button onClick={() => changeLocale('fr')}>French</button>
    </>
    </div>
  )
}

app/locales/client.ts

// locales/client.ts
"use client"
import { createI18nClient } from 'next-international/client'

export const { useI18n, useScopedI18n, I18nProviderClient } = createI18nClient({
  en: () => import('./en'),
  fr: () => import('./fr')
})

export const {
  useChangeLocale,
  useCurrentLocale,

} = createI18nClient({

})

app/locales/server.ts

// locales/server.ts
import { createI18nServer } from 'next-international/server'

export const { getI18n, getScopedI18n, getStaticParams } = createI18nServer({
  en: () => import('./en'),
  fr: () => import('./fr')
})

export const {
  getCurrentLocale,

} = createI18nServer({

})

Also in guide I see

export const {
  getCurrentLocale,
  ...
} = createI18nServer({
  ...
})

But if I keep ... it will throw the error

I expect that you send me MVP where internatiolazation work like / - english /fr - french

for example Because I don't want to have /en route for english language I want to have / route for english language

I see that you have some snippets without any locale define inside createI18nClient / createI18nServer: you have to pass an least one locale, as shown in the example.

Also in guide I see

export const { getCurrentLocale, ... } = createI18nServer({ ... }) But if I keep ... it will throw the error

Indeed you shouldn't copy the "...", it's just to simplify the example and not re-write the locale object. The full example would be:

export const { getCurrentLocale, useI18n, useScopedI18n, I18nProviderClient } = createI18nClient({
  en: () => import('./en'),
  fr: () => import('./fr')
})

As you can see, the getCurrentLocale function is retrieved from the same createI18nClient call, not a new one. Here are the full files:

// locales/client.ts
"use client"
import { createI18nClient } from 'next-international/client'

export const { useChangeLocale, useCurrentLocale, useI18n, useScopedI18n, I18nProviderClient } = createI18nClient({
  en: () => import('./en'),
  fr: () => import('./fr')
})

// locales/server.ts
import { createI18nServer } from 'next-international/server'

export const { getCurrentLocale, getI18n, getScopedI18n, getStaticParams } = createI18nServer({
  en: () => import('./en'),
  fr: () => import('./fr')
})

I'm still have /en instead of / for english language

I'm waiting for some minimal example I can just copy paste

[QuiiBz]

This is a totally unrelated thing, see the documentation that covers this feature: https://next-international.vercel.app/docs/app-middleware-configuration#rewrite-the-url-to-hide-the-locale

Inside your middleware, you have to use the urlMappingStrategy option as rewrite or rewriteDefault depending on what you want:

const I18nMiddleware = createI18nMiddleware({
  locales: ['en', 'fr'],
  defaultLocale: 'en',
  urlMappingStrategy: 'rewriteDefault' // or 'rewrite'
})

I'm waiting for some minimal example I can just copy paste

We do have both an example application and a CodeSandbox that you can refer too, along with the documentation.

rewriteDefault

As you see translation work only if I delete property you message me to set

Plese fix this issue

CodeSandbox doesn't work correctly with middlewares (notably with cookies), do you have the same issue when running the code locally?

CodeSandbox doesn't work correctly with middlewares (notably with cookies), do you have the same issue when running the code locally?

To reproduce:

1. fork this https://github.com/QuiiBz/next-international
2. git clone forked repository
3. cd examples
4. cd next-app
5. pnpm i

I tried to fix it with pnpm i next-international/middleware but got this

 pnpm i next-international/middleware

This is a separate issue, you have to build the packages locally since you're forking the repo. See the contributing guide: https://github.com/QuiiBz/next-international/blob/main/CONTRIBUTING.md

If you don't want to do so, just update the package.json to use the version published on npm instead of workspace:*
