Slack tokens are deprecated

[leonimurilo]

Slack tokens are deprecated and they are using what is called "slack apps". Is there a way of using this with slack apps?

I will do the changes and make a pull request.

The appender needs updating to use Slack's Webhooks API - I'd be happy to see a PR that implemented this. I'm guessing @leonimurilo found a different way to do what they needed to do 😄

You now have to create a Slack App within the workspace.

See https://api.slack.com/apps

When you did that, there is a link to add a webhook

https://api.slack.com/apps/APP_ID/incoming-webhooks?

You create one and get a webhook url.

This is the appender I wrote for this case

'use strict'

import request from 'request'

function slackAppender(config, layout) {
    return (loggingEvent) => {
        request.post(config.webhook, {
            json: { text: layout(loggingEvent, config.timezoneOffset) }
        }, (error, res, body) => {
            if (error) {
                console.error('log4js:slack - Error sending log to slack: ', err) //eslint-disable-line
                return
            }
            console.log(`statusCode: ${res.statusCode}`)
            console.log(body)
        })
    }
}

function configure(config, layouts) {
    let layout = layouts.basicLayout
    if (config.layout) {
        layout = layouts.layout(config.layout.type, config.layout)
    }

    return slackAppender(config, layout)
}

export default { configure: configure }

And the configuration

        slack: {
            type: slackLogger,
            webhook: 'THE WEBHOOK URL'
        }

I dont have much time right now, but you can use this to start the required change for this plugin to work again.

Of course you can also use the built in http lib :) @nomiddlename
