react-i18next/src/withSSR.js

Internationalization for react done right. Using the i18next i18n ecosystem.

import { createElement } from 'react';
import { useSSR } from './useSSR.js';
import { composeInitialProps } from './context.js';
import { getDisplayName } from './utils.js';

export const withSSR = () =>
  function Extend(WrappedComponent) {
    function I18nextWithSSR({ initialI18nStore, initialLanguage, ...rest }) {
      useSSR(initialI18nStore, initialLanguage);

      return createElement(WrappedComponent, {
        ...rest,
      });
    }

    I18nextWithSSR.getInitialProps = composeInitialProps(WrappedComponent);
    I18nextWithSSR.displayName = `withI18nextSSR(${getDisplayName(WrappedComponent)})`;
    I18nextWithSSR.WrappedComponent = WrappedComponent;

    return I18nextWithSSR;
  };
