void Singleton::readConfigFile() {
  std::string delimiter = "=";
  std::string line;
  std::ifstream configFileStream(this->configFile);

  if (configFileStream.is_open()) {
    while (getline(configFileStream, line)) {
      std::vector<std::string> v = split(line, delimiter);
      if (v.size() == 2) {
        configMap[v[0]] =
            v[1];  // Insert the key-value pair into the global configMap
      }
    }
    configFileStream.close();
  } else {
    // Handle file open error
  }
}
