Building an App for Removing Multiple Slack's Files

You're a developer. What do you do in your spare time? One of my most excited task for sharpening my skills is starting build a pet project.


Slack is cool! It's free. It supports for team collaboration very well.

However, my team only has storage limits due to a free account. We got a warning message as below:
Your file was uploaded — it’s safe and sound in Slack. Unfortunately your team doesn’t have any storage space left. To get more space, you can upgrade to a paid account or delete some of your older files.
Since my team plan of upgrading to a paid account is still up in the air, I intended to go with "deleting some of our older files" first. (But we will, Slack. You are great!)

Play Around

I got started by googling keyword "remove slack files". Here it is:

Uh huh! But I only could delete one file at a time.
We're afraid it's not possible to bulk delete files. We know that your business data is important to you — that's why we offer API methods to help you manage them.
How about removing the multiple files? Yeah! Slack is very cool again. They provide an API that I am able to bulk delete files:

Accordingly, I'm able to firstly call method "files.list" to obtain all files then I just need to loop the list to remove each file with method "file.delete".

Taking a look to the Slack API, I saw what I need to prepare is a "token" for building a very simple application.

In order to obtain a token, I just need to follow the following article. ;)

Let's go! I have made a test method "files.list" with Postman. Woo hoo! It worked.

Get Down To It

Now, I easily could build a REST client app to achieve this goal. With Java, I used Jersey as REST client API. The following are my steps:

  1. Setup environment: Eclipse, Git, JDK, Maven, Tomcat.
  2. Build a JSF Maven-based app and run on Tomcat 8
  3. Write a service to call the methods needed "files.list" and "files.delete"
  4. Refactor and put to Github. ;)

This is just my first draft, I'm still on my way to improve it. Anybody who wants to join me, you're are very welcome. ;)
