Translations and Locales
Learn How to Use Translations and Locales in Your NextKit Application
NextKit's codebase uses translations using the package i18next
.
- this package allows you to create multi-language apps effortlessly
- it also helps easily renaming the NextKit's entities according to your preferences: for example, renaming "organizations" to another entity such as "team" or "workspace"
- in a way, it helps write cleaner HTML
To add or update the default strings, you must use the locale files at public/locales/{lang}.json
. For example, all the locale files for the English language are placed under public/locales/en
.
When adding new keys, you'll need to restart the NextKit server (npm run dev
) to see the changes. Also, you may need to clear the browser cache since the client is hydrated with the translation files fetched from the JSON files.
The locales are split by functionality, page, or entity: as your application grows, you may not want to load every JSON file to reduce your bundle size.
For example, the translations for the authentication are placed in auth.json
, while the ones used across every page are placed under common.json.
If you are unsure where to add some translations, simply add them to common.json
.
To simplify things, the NextKit's starter uses all the available JSON files, and we recommend doing so until you have too many files.
Using Translations in Server Components
To use translations in Server Components, you can use the withI18n
higher order server component function, which wraps the server component and initializes i18n before rendering the component.
Adding new languages
By default, NextKit uses English for translating the website's text. All the files are stored in the files at /public/locales/en
.
Adding a new language is very simple:
- Translation Files: First, we need to create a new folder, such as
/public/locales/es
, and then copy over the files from the English version and start translating files. - Next.js i18n config: We need to also add a new language to the i18n configuration at
src/i18n/i18n.settings.ts
. Now add your new language's code to thelanguages
array.
The configuration will look like the below:
Setting the default Locale
To set the default locale, simply update the environment variable DEFAULT_LOCALE
stored in .env
.
So, open the .env
file, and update the variable:
Using the Language Switcher
The NextKit kits come with a language switcher that allows users to switch between the available languages. This is not enabled by default, but you can easily add it anywhere in your application by importing the LanguageSwitcherDropdown
component from ~/components/LanguageSwitcherDropdown
.
It does not require any props, and it will automatically detect the available languages and display them in a dropdown.
