Message formatting

winston-slack-webhook-transport supports the ability to format messages using Slack's message layout features. To do this, supply a custom formatter that supplies the requisite object structure to create the desired layout.

const winston = require("winston");
const SlackHook = require("winston-slack-transport-proxyfied");
 
const logger = winston.createLogger({
    level: "info",
    transports: [
        new SlackHook({
			webhookUrl: "https://hooks.slack.com/services/xxx/xxx/xxx",
			formatter: info => {
				return {
					text: `${info.level}: ${info.message}`,
					attachments: [
						{
							text: "Or don't pass anything. That's fine too"
						}
					],
					blocks: [
						{
							type: "section",
							text: {
								type: "plain_text",
								text: "You can pass more info to the formatter by supplying additional parameters in the logger call"
							}
						}
					]
				}
			}
        })
    ]
});

logger.info("Definitely try playing around with this.")
