Add or Load Translations

There are a few options to load translations to your application instrumented by i18next. The most common approach to this adding a so called backend plugin to i18next. The range of backends is large from loading translations in the browser using xhr request to loading translations from databases or filesystem in nodejs.

Add on init

You can add the translations on init

import i18next from 'i18next';
​
i18next
  .init({
    resources: {
      en: {
        namespace1: {
          key: 'hello from namespace 1'
        },
        namespace2: {
          key: 'hello from namespace 2'
        }
      },
      de: {
        namespace1: {
          key: 'hallo von namespace 1'
        },
        namespace2: {
          key: 'hallo von namespace 2'
        }  
      }
    }
  });

Add after init

You can add the translations after init

import i18next from 'i18next';
​
i18next.init();
i18next.addResourceBundle('en', 'namespace1', {
  key: 'hello from namespace 1'
});

There are more options to adding, removing translations...learn more about resource handling.

Load using a backend plugin

Each plugin comes with a set of on configuration settings like path to load resources from. Those settings are documented on the individual readme file of each repository.

Here is a sample using the i18next-xhr-backend to load resources from the server.

import i18next from 'i18next';
import Backend from 'i18next-xhr-backend';
​
i18next
  .use(Backend)
  .init({
    backend: {
      // for all available options read the backend's repository readme file
      loadPath: '/locales/{{lng}}/{{ns}}.json'
    }
  });
