Description

Purpose: dump Slack messages, users and files using browser token and cookie.

Typical use scenarios:

• archive your private conversations from Slack when the administrator does not allow you to install applications OR you don't want to use potentially privacy-violating third-party tools,
• archive channels from Slack when you're on a free "no archive" subscription, so you don't lose valuable knowledge in those channels.
• create a Slack Export archive without admin access.

There a three modes of operation (more on this in User Guide) :

1. List users/channels
2. Dumping messages and threads
3. Creating a Slack Export.

Slackdump accepts two types of input (see Dumping Conversations section):

1. the URL/link of the channel or thread, OR
2. the ID of the channel.

Quick Start

Please see the User Guide.

Using as a library

Download:

go get github.com/rusq/slackdump/v2

Add the following line at the end of your project's go.mod file:

replace github.com/slack-go/slack => github.com/rusq/slack v0.11.100

This is required, as Slackdump relies on custom authentication scheme that uses cookies, and those functions are simply not in the original library.

Example

import (
  "github.com/rusq/slackdump/v2"
  "github.com/rusq/slackdump/v2/auth"
)

func main() {
  provider, err := auth.NewValueAuth("xoxc-...", "xoxd-...")
  if err != nil {
      log.Print(err)
      return
  }
  sd, err := New(context.Background(), provider)
  if err != nil {
      log.Print(err)
      return
  }
  _ = sd
}

Using Custom Logger

Slackdump uses a simple rusq/dlog as a default logger (it is a wrapper around the standard logger that adds Debug* functions). Of course, everyone has their own favourite logger that is better than other miserable loggers. Please read below for instructions on your favourite logger.

Logrus

Good news is logrus can be plugged in straight away, as it implements the logger.Interface out of the box.

lg := logrus.New()
sd, err := New(context.Background(), provider, WithLogger(lg))
  if err != nil {
      log.Print(err)
      return
  }
}

Glog and others

If you need to use some other logger, such as glog, it is a matter of wrapping the calls to satisfy the logger.Interface (defined in the logger package), and then setting the Logger variable in slackdump.Options (see options.go), or using WithLogger option.

FAQ

Q:	Do I need to create a Slack application?
A:	No, you don't. Just run the application and EZ-Login 3000 will take care of the authentication or, alternatively, grab that token and cookie from the browser Slack session. See User Guide.
Q:	I'm getting "invalid_auth" error
A:	Go get the new Cookie from the browser and Token as well.
