import { AxiosRequestConfig } from "axios";

import { ClientConfigDto, ClientHeadersConfigDto } from "../config";

export const toAxiosConfig = (config: ClientConfigDto): AxiosRequestConfig => {
  const headers = config.headers
    ? Object.fromEntries(
        Object.entries(config.headers as ClientHeadersConfigDto).filter(
          ([, value]) => value !== undefined,
        ),
      )
    : {};

  return {
    ...config,
    headers,
  };
};
