Stackdriver Logging stream for Bunyan

This module provides an easy to use, higher-level layer for working with Stackdriver Logging, compatible with Bunyan. Simply use this as a raw stream with your existing Bunyan loggers.

For lower-level access to the Stackdriver Logging API, see @google-cloud/logging.

This module is experimental and should be used by early adopters. This module uses APIs that may be undocumented and subject to change without notice.

$ npm install --save @google-cloud/logging-bunyan

var bunyan = require('bunyan');
var loggingBunyan = require('@google-cloud/logging-bunyan')();

var logger = bunyan.createLogger({
  name: 'my-service',
  streams: [
    loggingBunyan.stream('info')
  ]
});

logger.error('warp nacelles offline');
logger.info('shields at 99%');

Authentication

It's incredibly easy to get authenticated and start using Google's APIs. You can set your credentials on a global basis as well as on a per-API basis. See each individual API section below to see how you can auth on a per-API-basis. This is useful if you want to use different accounts for different Google Cloud services.

On Google Cloud Platform

If you are running this client on Google Cloud Platform, we handle authentication for you with no configuration. You just need to make sure that when you set up the GCE instance, you add the correct scopes for the APIs you want to access.

var loggingBunyan = require('@google-cloud/logging-bunyan')();
// ...you're good to go!

Elsewhere

If you are not running this client on Google Cloud Platform, you need a Google Developers service account. To create a service account:

1. Visit the Google Developers Console.
2. Create a new project or click on an existing project.
3. Navigate to APIs & auth > APIs section and turn on the following APIs (you may need to enable billing in order to use these services):

• Stackdriver Logging API

1. Navigate to APIs & auth > Credentials and then:

• If you want to use a new service account key, click on Create credentials and select Service account key. After the account key is created, you will be prompted to download the JSON key file that the library uses to authenticate your requests.
• If you want to generate a new service account key for an existing service account, click on Generate new JSON key and download the JSON key file.

var projectId = process.env.GCLOUD_PROJECT; // E.g. 'grape-spaceship-123'

var loggingBunyan = require('@google-cloud/logging-bunyan')({
  projectId: projectId,

  // The path to your key file:
  keyFilename: '/path/to/keyfile.json'

  // Or the contents of the key file:
  credentials: require('./path/to/keyfile.json')
});

// ...you're good to go!
