Crystal - Slack Clean Up

You have a free Slack account, so your have limited storage and you're getting warnings already. You can now just clean up old uploaded files with this tool.

Installation

You can build the executable like this:

crystal build src/cr_slack_cleanup.cr --release

Usage

You can run this tool against your own Slack account like this:

./cr_slack_cleanup --domain=your_domain --token=aaaa-0000000000-0000000000-000000000-0000000000

Development

TODO: There are no tests in this project, unfortunatelly. Because it's basically an external HTTP consumer we'd need something like VCR to make better tests.

I originally did an Elixir version that has a very high concurrency and therefore it's also a good candidate for a Crystal implementation using the new Channel feature.

You can check out the original Elixir source code here

In a simple test to delete 9 images from my Slack account the Elixir version performed like this:

0,38s user 0,14s system 17% cpu 2,919 total

Then I uploaded the same set of images again and ran the Crystal version and it performed like this:

0,03s user 0,01s system 2% cpu 1,835 total

The Crystal version not only ran much faster (startup and execution time) but also used much less resources.
