bunyan-rollbar

If you're using Bunyan for logging, this custom stream can be used to send your error logs to Rollbar.

Example

var bunyan = require('bunyan')
var bunyanRollbar = require('bunyan-rollbar')

// Tested with v2.1.0 of rollbar
// You can pass in your own version of rollbar
var Rollbar = require('rollbar')
var rollbar = new Rollbar('POST_SERVER_ITEM_ACCESS_TOKEN')

// We strongly recommend you patch Bunyan's standard serializers. See the notes below.
// This will *mutate* bunyan.stdSerializers.{err,req}.
bunyan.stdSerializers.req = bunyanRollbar.patchSerializer(bunyan.stdSerializers.req)
bunyan.stdSerializers.err = bunyanRollbar.patchSerializer(bunyan.stdSerializers.err)

var logger = bunyan.createLogger({
  name: 'mylogger',
  streams: [
    {
      level: 'error',
      type: 'raw', // Must be set to raw for use with BunyanRollbar
      stream: new bunyanRollbar.Stream(rollbar)
    }
  ],
  serializers: bunyan.stdSerializers
})

Serializers

If you plan to use Bunyan's standard serializers, it's recommended you use the standard serializers from this library instead. You should also overwrite bunyan.stdSerializers.err with the version from this library. The serializers provided by this library include all the same standard serializers as Bunyan, but are modified to retain the original error and request objects so Rollbar can apply its own custom processing to those specific types of objects.

// Override
bunyan.stdSerializers.err = bunyanRollbar.stdSerializers.err;
var logger = bunyan.createLogger({
  name: 'mylogger',
  serializers: bunyanRollbar.stdSerializers,
})
