Code sample

C++

Before trying this sample, follow the C++ setup instructions in the Workflows quickstart using client libraries.

To authenticate to Workflows, set up Application Default Credentials. For more information, see Set up authentication for a local development environment. 

#include "google/cloud/workflows/v1/workflows_client.h"
#include "google/cloud/location.h"
#include <iostream>

int main(int argc, char* argv[]) try {
  if (argc != 3) {
    std::cerr << "Usage: " << argv[0] << " project-id location-id\n";
    return 1;
  }

  auto const location = google::cloud::Location(argv[1], argv[2]);

  namespace workflows = ::google::cloud::workflows_v1;
  auto client =
      workflows::WorkflowsClient(workflows::MakeWorkflowsConnection());

  for (auto w : client.ListWorkflows(location.FullName())) {
    if (!w) throw std::move(w).status();
    std::cout << w->DebugString() << "\n";
  }

  return 0;
} catch (google::cloud::Status const& status) {
  std::cerr << "google::cloud::Status thrown: " << status << "\n";
  return 1;
}

Node.js

Before trying this sample, follow the Node.js setup instructions in the Workflows quickstart using client libraries. For more information, see the Workflows Node.js API reference documentation.

To authenticate to Workflows, set up Application Default Credentials. For more information, see Set up authentication for a local development environment. 

const {WorkflowsClient} = require('@google-cloud/workflows');
const client = new WorkflowsClient();

/**
 * TODO(developer): Uncomment these variables before running the sample.
 */
// const projectId = 'my-project';
// const location = 'us-central1';

async function listWorkflows(projectId, location) {
  const [workflows] = await client.listWorkflows({
    parent: client.locationPath(projectId, location),
  });
  for (const workflow of workflows) {
    console.info(`name: ${workflow.name}`);
  }
}

listWorkflows(projectId, location).catch(err => {
  console.error(err.message);
  process.exitCode = 1;
});
