/*

Hey All! Most devs (including me) uses Proxy and Decorators on a daily basis but doesn't know to implement or use one. I wanted to show two snippets me and @Nicolas Mendzylewski wrote that might be useful in the future:



const withOBAPIAuth = function withOBAPIAuthenticationToken(proto) {
  const handler = {
    get(target, propKey) {
      const method = target[propKey];
      const { token } = proto;
      if (typeof method === 'function' && method !== proto) {
        return async (...args) => {
          let result;
          try {
            result = await method.apply(proto, args);
          } catch (error) {
            console.error('failed fetching data from remote service', { error });
            if (error.statusCode === 401) {
              proto.token = await getToken();
              result = await method.apply(proto, args);
            }
          }
          return result;
        };
      }

      return method;
    },
  };
  return new Proxy(proto, handler);
}; */
