  channel: '#your_channel',
  username: 'your_username',
  onError: function(error) {

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

  stream: new BunyanChat({
    type: 'slack',
    webhookUrl: 'your_webhook_url',
    channel: '#your_channel',
    username: 'your_username',
    customFormatter: function(record, levelName) {
      return { text: '[' + levelName + '] ' + record.msg };
    },
  }),
  level: 'error',
});

Using slack message attachments

import Bunyan from 'bunyan';
import { BunyanChat } from 'bunyan-chat';

const log = bunyan.createLogger({
  name: 'myapp',
  stream: new BunyanChat({
    type: 'slack',
    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: 'Bunyan chat',
            author_link: 'your_author_link',
            author_icon: 'your_author_icon',

            fields: [
              {
                title: 'We have a new ' + levelName + ' log',
                value: ':scream_cat: ' + record.msg,
                short: true,
              },
            ],
          },
        ],
      };
    },

Using discord embeds

  name: 'myapp',
  streams: [
    {
      type: 'raw',
      stream: new BunyanChat({
        type: 'discord' as const,
        webhookUrl: 'mywebhookurl',
        customFormatter: (record: any, levelName: string) => {
          return {
            embeds: [
              {
                color: 7019426,
                title: 'Discord API Documentation',
                url: 'https://discord.com/developers/docs/intro',
                description: 'Optional text that appears within the attachment',

                fields: [
                  {
                    name: `We have a new ${levelName} log`,
                    value: `${record.msg}`,
                  },
                ],
              },
