# README

Is an easy to use integration for [Next.js](https://nextjs.org/) to enable [i18next](https://www.i18next.com/) translations on your application with support for SSR, SSG and Client translation loading.

![](/files/EeOrEHqP2aqCP7wNTPis)

It gives you freedom to use `i18next` with a lot of different customizations, while still being compatible with `next.js`.

`Ni18n` also does not directly depend on `i18next` nor `react-i18next`, allowing you to update these dependencies without having to wait for any action on our part.

## Installing

```bash
yarn add i18next react-i18next ni18n
```

```bash
npm install i18next react-i18next ni18n
```

```typescript
import {
  appWithI18Next,
  loadTranslations,
  clientNamespaces,
  useSyncLanguage,
} from 'ni18n'
```

## Getting Started

Read the docs at [Getting Started](/ni18n/usage/getting-started.md) or on the website <https://jcquintas.gitbook.io/ni18n/usage/getting-started>

## Known Issues

When running on Vercel we are unable to load the translation files automatically because the [vercel/nft](https://github.com/vercel/nft) package doesn't bundle files requested by a third party lib.

A work around is to create a wrapper around `loadTranslations` that calls `path.resolve('./', './public/locales')`, and then use this function instead of the exported by the `ni18n` package.

```typescript
import { loadTranslations as ni18nLoadTranslations } from 'ni18n'
import { ni18nConfig } from '../ni18n.config'

export const loadTranslations = async (
  initialLocale?: string | undefined,
  namespacesNeeded?: NamespacesNeeded | undefined,
) => {
  const locales = path.resolve('./', './public/locales')

  return await ni18nLoadTranslations(
    ni18nConfig,
    initialLocale,
    namespacesNeeded,
  )
}
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://jcquintas.gitbook.io/ni18n/readme.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
