Quickstart

Before you begin

1. Select or create a Cloud Platform project.

   Go to the projects page

2. Enable billing for your project.

   Enable billing

3. Enable the Stackdriver Logging API.

   Enable the API

4. Set up authentication with a service account so you can access the
   API from your local workstation.

Installing the client library

npm install --save @google-cloud/logging

Using the client library

// Imports the Google Cloud client library
const {Logging} = require('@google-cloud/logging');

// Your Google Cloud Platform project ID
const projectId = 'YOUR_PROJECT_ID';

// Creates a client
const logging = new Logging({
  projectId: projectId,
});

// The name of the log to write to
const logName = 'my-log';
// Selects the log to write to
const log = logging.log(logName);

// The data to write to the log
const text = 'Hello, world!';
// The metadata associated with the entry
const metadata = {resource: {type: 'global'}};
// Prepares a log entry
const entry = log.entry(metadata, text);

// Writes the log entry
log
  .write(entry)
  .then(() => {
    console.log(`Logged: ${text}`);
  })
  .catch(err => {
    console.error('ERROR:', err);
  });

Versioning

This library follows Semantic Versioning.

This library is considered to be General Availability (GA). This means it
is stable; the code surface will not change in backwards-incompatible ways
unless absolutely necessary (e.g. because of critical security issues) or with
an extensive deprecation period. Issues and requests against GA libraries
are addressed with the highest priority.
