Create next specific code

See #201 for working starting points

Just copied this code into a third project:

import React from 'react';
import PropTypes from 'prop-types';
import { curry } from 'ramda';
import Error from 'next/error';
import {
  getCurrentActiveFeatureNames,
  isActiveFeatureName,
} from '@paralleldrive/feature-toggles';

const configureNextPageFeature = (
  initialFeatures,
  featureName,
  ComposedComponent
) => {
  const getComposedComponentsInitialProps = ctx =>
    ComposedComponent.getInitialProps
      ? ComposedComponent.getInitialProps(ctx)
      : {};

  const NextPageFeature = ({ statusCode, ...rest }) =>
    statusCode === 200 ? (
      <ComposedComponent {...rest} />
    ) : (
      <Error statusCode={statusCode} />
    );

  NextPageFeature.getInitialProps = async ctx => {
    const { res, req, err } = ctx;

    const activeFeaturesNames = getCurrentActiveFeatureNames({
      initialFeatures,
      req,
    });

    if (res && !isActiveFeatureName(featureName, activeFeaturesNames))
      res.statusCode = 404;

    const statusCode = res ? res.statusCode : err ? err.statusCode : null;

    return {
      ...(await getComposedComponentsInitialProps(ctx)),
      statusCode,
    };
  };

  NextPageFeature.propTypes = {
    statusCode: PropTypes.number.isRequired,
  };

  return NextPageFeature;
};

export default curry(configureNextPageFeature);

Do we have something like this in the library yet?
