Bunyan stream for Slack chat integration

First install bunyan...

npm install bunyan

Then install bunyan-slack

npm install bunyan-slack

Basic Setup

const bunyan = require('bunyan');
const BunyanSlack = require('bunyan-slack');

const log = bunyan.createLogger({
  name: 'myApp',
  streams: [
    {
      type: 'raw',
      stream: new BunyanSlack({
        webhookUrl: 'your_webhook_url',
        channel: '#your_channel',
        username: 'your_username',
      }),
    },
  ],
  level: 'error',
});

log.error('hello bunyan slack');

You can also pass an optional error handler.

Specify a Slack channel by name with "channel": "#other-channel", or send a Slackbot message to a specific user with "channel": "@username".

const stream = new BunyanSlack({
  webhookUrl: 'your_webhook_url',
  channel: '#your_channel',
  username: 'your_username',
  onError: function(error) {
    console.log(error);
  },
});

Custom Formatters

By default the logs are formatted like so: [LOG_LEVEL] message, unless you specify a customFormatter function.

const log = bunyan.createLogger({
  name: 'myApp',
  stream: new BunyanSlack({
    webhookUrl: 'your_webhook_url',
    channel: '#your_channel',
    username: 'your_username',
    customFormatter: function(record, levelName) {
      return { text: '[' + levelName + '] ' + record.msg };
    },
  }),
  level: 'error',
});

Custom Formatter Options

Check the slack docs for custom formatter options.

Putting it all together

const bunyan = require('bunyan');
const BunyanSlack = require('bunyan-slack');

const log = bunyan.createLogger({
  name: 'myapp',
  stream: new BunyanSlack({
    webhookUrl: 'your_webhook_url',
    iconUrl: 'your_icon_url',
    channel: '#your_channel',
    username: 'your_username',
    iconEmoji: ':scream_cat:',
    customFormatter: function(record, levelName) {
      return {
        attachments: [
          {
            fallback: 'Required plain-text summary of the attachment.',
            color: '#36a64f',
            pretext: 'Optional text that appears above the attachment block',
            author_name: 'Seth Pollack',
            author_link: 'http://sethpollack.net',
            author_icon: 'http://www.gravatar.com/avatar/3f5ce68fb8b38a5e08e7abe9ac0a34f1?s=200',
            title: 'Slack API Documentation',
            title_link: 'https://api.slack.com/',
            text: 'Optional text that appears within the attachment',
            fields: [
              {
                title: 'We have a new ' + levelName + ' log',
                value: ':scream_cat: ' + record.msg,
                short: true,
              },
            ],
          },
        ],
      };
    },
  }),
  level: 'error',
});
