Dark mode for Slack on MacOS

dark.md

1. Close slack
2. Open this file /Applications/Slack.app/Contents/Resources/app.asar.unpacked/src/static/ssb-interop.js
3. Append this to it

document.addEventListener('DOMContentLoaded', function() {
 $.ajax({
   url: 'https://cdn.rawgit.com/laCour/slack-night-mode/master/css/raw/black.css',
   success: function(css) {
     $("<style></style>").appendTo('head').html(css);
   }
 });
});

4. Open slack and enjoy the darkness!

On linux I edited:
/usr/lib/slack/resources/app.asar.unpacked/src/static/ssb-interop.js

Thanks for this! works great

Yay! Thank you!

Works perfectly! Thanks!

To get white menu links:

document.addEventListener('DOMContentLoaded', function() {
  let tt__customCss = `.menu ul li a:not(.inline_menu_link) {color: #fff !important;}`
  $.ajax({
      url: 'https://cdn.rawgit.com/laCour/slack-night-mode/master/css/raw/black.css',
      success: function(css) {
          $("<style></style>").appendTo('head').html(css + tt__customCss);
      }
  });
});

Thanks! This is great including the fix for menu items! :)

Where to find this file if using Slack in Station app?

This worked great!

When replying to a thread, the typed out text is hard to see. Any suggestions on making this darker?

@indradhanush quick fix

comment thread

$("<style></style>").appendTo('head').html('#reply_container.upload_in_threads .inline_message_input_container {background: padding-box #545454}')

purple channel nav bar -> dark grey

$("<style></style>").appendTo('head').html('.p-channel_sidebar {background: #363636 !important}'); 

I made a quick shell script to automate the process, if you'd like. Here you go!

@samjhill your shell script worked great! Thanks for making it so easy 💯

Windows file location: %LOCALAPPDATA%\slack\app-[version]\resources\app.asar.unpacked\src\static

To get white menu links:

document.addEventListener('DOMContentLoaded', function() {
  let tt__customCss = `.menu ul li a:not(.inline_menu_link) {color: #fff !important;}`
  $.ajax({
      url: 'https://cdn.rawgit.com/laCour/slack-night-mode/master/css/raw/black.css',
      success: function(css) {
          $("<style></style>").appendTo('head').html(css + tt__customCss);
      }
  });
});

you need to add this line as well:

#client_body:not(.onboarding):not(.feature_global_nav_layout):before {
    background: inherit;
}

it will fix some more white areas in the sidebar

We still need some love in the search results - currently very hard to read.

BTW the script link from the snippet is always updates, you might not need some of the custom fixes if it was fixed

I appended the following:
and now when i open slack it just spins on the welcome message... suggestions?

document.addEventListener('DOMContentLoaded', function() { let tt__customCss = .menu ul li a:not(.inline_menu_link) {color: #fff !important;} $.ajax({ url: 'https://cdn.rawgit.com/laCour/slack-night-mode/master/css/raw/black.css', success: function(css) { $("<style></style>").appendTo('head').html(css + tt__customCss); } }); });

Oddly enough i had to reinstall slack for some reason, just overwrote previous install and applied changed. THANKS OP

Thanks all. Works great. Here is everything in the thread up to this point all nice and pretty:

On mac you can easy add the code as follows:

1. Copy paste the following into the terminal but DO NOT PRESS RETURN:
   pbpaste >> /Applications/Slack.app/Contents/Resources/app.asar.unpacked/src/static/ssb-interop.js

2. Then add the following snippet to your clipboard a la command+c

document.addEventListener('DOMContentLoaded', function() {
  let tt__customCss = `.menu ul li a:not(.inline_menu_link) {color: #fff !important;}`
  $.ajax({
      url: 'https://cdn.rawgit.com/laCour/slack-night-mode/master/css/raw/black.css',
      success: function(css) {
          $("<style></style>").appendTo('head').html(css + tt__customCss);
          $("<style></style>").appendTo('head').html('#reply_container.upload_in_threads .inline_message_input_container {background: padding-box #545454}');
          $("<style></style>").appendTo('head').html('.p-channel_sidebar {background: #363636 !important}'); 
          $("<style></style>").appendTo('head').html('#client_body:not(.onboarding):not(.feature_global_nav_layout):before {background: inherit;}'); 
      }
  });
});

3. Then go back to terminal and press enter. It will dump your clipboard into the file.

@codyolsen You have to use root to write into Applications folder.
So, the command will be pbpaste | sudo tee -a /Applications/Slack.app/Contents/Resources/app.asar.unpacked/src/static/ssb-interop.js

Thanks @codyolsen for the summary! Works great!!

Thanks for gisting this! After upgrading to Mojave, slack's white back ground was piercing my eyes.

If you want to be a bit cautious on the security front, you can download the css from https://cdn.rawgit.com/laCour/slack-night-mode/master/css/raw/black.css to a file (i.e. /Applications/Slack.app/Contents/Resources/slack-black.css) and load it from disk instead of over the internet.

This worked for me, thanks to the above posts from @codyolsen and @marchrius.

Add this to /Applications/Slack.app/Contents/Resources/app.asar.unpacked/src/static/ssb-interop.js:

document.addEventListener('DOMContentLoaded', function() {
  let fs = require('fs');
  let filePath = '/Applications/Slack.app/Contents/Resources/slack-black.css';
  let tt__customCss = `.menu ul li a:not(.inline_menu_link) {color: #fff !important;}`
  fs.readFile(filePath, {encoding: 'utf-8'}, function(err, css) {
    if (!err) {
      $("<style></style>").appendTo('head').html(css + tt__customCss);
      $("<style></style>").appendTo('head').html('#reply_container.upload_in_threads .inline_message_input_container {background: padding-box #545454}');
      $("<style></style>").appendTo('head').html('.p-channel_sidebar {background: #363636 !important}');
      $("<style></style>").appendTo('head').html('#client_body:not(.onboarding):not(.feature_global_nav_layout):before {background: inherit;}');
    }
  });
});

Thanks jlucier. I did get caught out by one small issue with your instructions - may be helpful for others to look out for this. The css file was named black.css, but when you copy it to the Slack app, you need to remember to change its name to slack-black.css

@jlucier Unfortunately local file loading did not work for me... so I have to use the 'Ajax' method

Thanks.

thanks @jlucier, if you want to make it easier to do the changes:

Any idea how to use this with Franz?

Any idea how to use this with Franz?

Would love to know this as well

If someone could take the time to do a darcula theme I will nut on video.

Sidebar was still not quite what I wanted it to be. I'm using these colors to customize the rest of the client.

#2A2A2A,#2A2A2A,#454647,#FFFFFF,#454647,#FFFFFF,#3DBA0F,#EF4933

@b3none why not do it yourself then ;)

For some reason this morning my reply in threads is now white again. Anyone else run into this? It has been working for months and even after I updated to 3.3.6.
