使用webpack provideplugin全局导入javascript文件

我有一个函数来进行网络调用,我希望该函数在全球范围内可用,而不必每次需要使用该函数时都导入它

请求程序

import 'whatwg-fetch';

/**
 * Parses the JSON returned by a network request
 *
 * @param  {object} response A response from a network request
 *
 * @return {object}          The parsed JSON from the request
 */
function parseJSON(response) {
  if (response.status === 204 || response.status === 205) {
    return null;
  }
  return response.json();
}

/**
 * Checks if a network request came back fine, and throws an error if not
 *
 * @param  {object} response   A response from a network request
 *
 * @return {object|undefined} Returns either the response, or throws an error
 */
function checkStatus(response) {
  if (response.status >= 200 && response.status < 300) {
    return response;
  }
  const error = new Error(response.statusText);
  error.response = response;
  throw error;

}

/**
 * Requests a URL, returning a promise
 *
 * @param  {string} url       The URL we want to request
 * @param  {object} [options] The options we want to pass to "fetch"
 *
 * @return {object}           The response data
 */
export default function request(url, options) {
  return fetch(url, options)
    .then(checkStatus)
    .then(parseJSON);
}

webpack.config.js文件

    plugins: [
      new webpack.ProvidePlugin({
        fetch: 'exports-loader?self.fetch!whatwg-fetch',
        request : require.resolve(path.join(process.cwd(),'app/utils/request.js'))
      })]

因此,当我尝试在任何其他文件中使用request函数时,它会抛出一个错误,说“module not found”。我也试着增加一条规则( Shimming )也没能成功。

提前谢谢:)
