Slack Logging Plugin

A plugin for logger-nodejs that allows you to send logs to slack

Usage:

const Logger = require('logger-nodejs');
const SlackPlugin = require('logger-nodejs-slack-plugin');

const slackPlugin = new SlackPlugin({
    webhook: 'https://hooks.slack.com/services/your/webhook',
    channel: '#api-errors',
    username: 'API',
    logLevel: 'error'
});

const log = new Logger({ plugins: [slackPlugin] });

• Now, every message of at least level error will be sent to the configured slack channel.

Configuration Options:

• The following properties can be provided during instantiation:
  • webhook (required): The url provided by slack
  • channel (required): The channel you want messages sent to
  • username (required): The username you want to use for these slack messages
  • logLevel: The minimum log level. See here for all available log levels
  • levelChannels: An object containing keys as log levels and channel names for those log levels. This allows you to send logs of different levels to different channels.

  {
      "fatal": "#general",
      "error": "#errors"
  }

Alternative Usage:

• You can also choose what messages to send to slack on a per-message basis like so:

const Logger = require('logger-nodejs');
const SlackPlugin = require('logger-nodejs-slack-plugin');

const slackPlugin = new SlackPlugin({
    webhook: 'https://hooks.slack.com/services/your/webhook',
    channel: '#api-errors',
    username: 'API',
});

const log = new Logger({ plugins: [slackPlugin] });

log.info('Application Started!', { notifySlack: true });

• You can prevent certain messages from getting sent to slack by setting notifySlack to false
