Add or import languages in a JSS Next.js app

Version: 22.x

When working in a JSS Next.js project, you might need to deploy new languages or import previously deployed languages and items in that language.

Add a language to the Next.js project

The Next.js JSS application created when you create your development project has examples for multilingual Styleguide components that have language routes. For the language routes to work, you must add the language for those routes to Sitecore.

To add a new language to the CM instance in the Next.js project:

Add the language to /sitecore/system/Languages. The Next.js sample app uses Danish (da-DK).

Deploy the items in that language:

RequestResponse

jss deploy items --language=da-DK --includeContent --includeDictionary

Publish the language:
RequestResponse
```
dotnet sitecore publish
```

Import a deployed language to your serialized items

To import items for a previously deployed language into the serialized items of your containerized project:

In the file src/InitItems.module.json in your containerized project, add a serialization configuration for languages. For example:

RequestResponse

{
       "name": "languages",
       "path": "/sitecore/system/Languages",
       "scope": "descendantsOnly",
       "rules": [
           {
               "path": "/en",
               "scope": "ignored"
           }
       ]
   }

In a terminal, in the root directory of the project, run the following command:
RequestResponse
```
dotnet sitecore ser pull
```
