--- tags: brew-js-react --- # Integration with i18n It is common to have (usually) the first path segment to specifiy the language of content being rendered. The i18n module is readily working with the router: ```typescript import brew from "brew-js-react"; import i18n from "brew-js/extensions/i18n"; import router from "brew-js/extensions/router"; brew.with(router)(app => { app.useRouter({ routes: [ '/{language:[a-zA-z-]+}/{view}/*', '/*' ], baseUrl: '/' }); app.useI18n({ languages: ['en', 'de'], routeParam: 'language' }); }); ``` In the above example, the i18n module will monitor the `langauge` route parameter (the first segment, accessible through `app.route.language`), and either set current language (`app.language`) to the specified one, or redirects the SPA to a path starting with the allowed default language.
