node-honeybadger

node-honeybadger is a node.js module for sending errors and related metadata to honeybadger.io.

It is small, lightweight, and uses the stack-trace module to give honeybadger the stack trace format it expects, allowing node.js stack traces to show up properly in the honeybadger UI.

Usage is simple:

var Badger = require('node-honeybadger');

var hb = new Badger({
  apiKey: 'your api key goes here',
  server: { hostname: 'steve', otherMetadata: 'goes here' },
  // Any object with info, warn, and error methods can be used as the logger.
  // If nothing is provided, nothing will be logged.
  logger: console
});

var err = new Error('FLAGRANT ERROR!');

err.name = 'FlagrantError'

// The second argument is error tracking metadata, like user/session id
hb.send(err, {
  context: {
    user: 'jane',
    email: '[email protected]'
  },
  session: {},
  cookies: {},
  params: {},
  cgi_data: req.headers
});

The cgi_data metadata field is important - this is what populates the "Environment" section of the Honeybadger error UI. It usually contains HTTP headers and other server info, in the Ruby frameworks that Honeybadger mainly supports - since there is no sensible default in node for this, populating this field effectively is left as an exercise to the user.

Instances of node-honeybadger can also emit the following events:

• sent: This is emitted when honeybadger.io returns a 201 successfully. The response body, containing metadata about the submitted error, is emitted as data.
• error: Emitted in the case of local node errors while trying to connect to honeybadger.io. Will not be emitted unless a listener is present.
• remoteError: Emitted when a non-201 status code is returned by honeybadger.io. Emits the response body, if one is present.

Prior to version 0.4.0, node-honeybadger was a Writable Stream. This interface has been removed, since it was only wishful thinking in the first place, and did not make a lot of sense in practice.
