A dark theme for Slack

How to add the dark theme to slack

1. Locate Slack's ssb-interop.js file
   • For PC users, go to your version (your own username and current app version) of C:\Users\username\AppData\Local\slack\app-3.1.0\resources\app.asar.unpacked\src\static Note that if your slack client updates (it does this quietly without telling you), you'll need to do this process again for the updated version.
   • For Linux users, using the slack desktop (beta) navigate to /lib/slack/resources/app.asar.unpacked/src/static
   • Mac users, go to your version of /Applications/Slack.app/Contents/Resources/app.asar.unpacked/src/static
2. open ssb-interop.js with your editor of choice.
3. Add this code to the end of ssb-interop.js and save:

document.addEventListener('DOMContentLoaded', function () {
    $.ajax({
        url: 'https://raw.githubusercontent.com/earlduque/Slack-Dark-Theme/master/dark.css',
        success: function (css) {
            $("<style></style>").appendTo('head').html(css);
        }
    });
});

4. close and reopen slack

Further, I like this as the sidebar coloring:

1. on the channel list at the top, click on your name and go to preferences
2. click on sidebar
3. scroll down and click on advanced/custom theme
4. paste this into the custom theme input box: #363636,#444A47,#D39B46,#FEFEFE,#434745,#FEFEFE,#99D04A,#DB6668
5. Or just copy and paste the code block above into any chat message to yourself or another person. Then you will see a button appear saying "Switch sidebar theme"
