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
}

Custom Logger

Slackdump uses rusq/dlog as a default logger. If you need to plug in some other logger, such as logrus or glog, it is simply a matter of wrapping the calls of the logger of your choice, to satisfy the logger.Interface (defined in the logger package), and then setting the Logger option in slackdump.Options (see options.go).

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.
