A code sample from the article https://joshwulf.com/blog/2020/03/camunda-cloud-connection-2/

GrpcConnectionFactory.ts

export class GrpcConnectionFactory {
  private static autodetect(config: GrpcClientCtor): GrpcConnectionProfile {
    const isCamundaCloud = config.host.includes('zeebe.camunda.io')
    return isCamundaCloud ? 'CAMUNDA_CLOUD' : 'VANILLA'
  }
  public static getGrpcClient(config: GrpcClientCtor) {
    const profile = GrpcConnectionFactory.autodetect(config)
    const grpcClient = new GrpcClient(config)
    new GrpcMiddleware({ profile, grpcClient })
    return new GrpcClient(config)
  }
}
