Based on wja-no/winston-slack. Rewritten in TypeScript.

Winston Transport for Slack chat integration.

npm install --save @aaaahoang123/winston-slack

Basic transport that works just like all other winston transports. Sends logged messages to a specified Slack chat channel.

Configuration options:

• webhook_url: required The webhook URL, something like https://hooks.slack.com/services/XXXXXXXXX/YYYYYYYYY/ZZZZZZZZZZZZZZZZZZZZZZZZ
• level: If specified, this logger will only log messages at the specified level of importance and more important messages
• format: use require('logform').Format as original winston

const { createLogger, format, transports } = require('winston');
const { combine, timestamp, label, prettyPrint } = format;

{
    format: combine(
           label({ label: 'right meow!' }),
           timestamp(),
           prettyPrint()
   )
}

Additionally, you can specify any Slack message parameters (such as username and channel), and it will be applied as a fallback if the given argument is not specified per message.

var winston = require('winston');
var Slack = require('@aaaahoang123/winston-slack');

winston.add(Slack, {
    webhook_url: "https://hooks.slack.com/services/XXXXXXXXX/YYYYYYYYY/ZZZZZZZZZZZZZZZZZZZZZZZZ",
    channel: "#test-channel",
    username: "ErrorBot",
    level: 'error',
    handleExceptions: true
});
