Dark/Light Mode Toggle

I believe a light scheme and dark scheme will be auto assigned once an admin enables it. From there, a user can edit which dark and light color schemes are used as their personal preference.

You may have to also add a selection here /admin/site_settings/category/basic?filter=dark

I have updated the instructions to reflect this addition. Sorry for the confusion!

It seems doesn’t work correctly when the default color scheme is dark. How can we adapt this?

When the default color scheme is dark, toggle does not work unless a user has select light color scheme from the interface preferences.

Hmmm, I believe this is happening because I am checking for prefers-dark user scheme settings based on the browser and system settings.

Can you look at your inspector console and see if anything is coming up when trying to use the toggle?

I may have to look into this.

Same here. Dark light component throwing errors.

Hmmm… not sure where that is coming from as I have no code that should send that out. The only communication I have for an error is here:

https://github.dev/discourse/discourse-color-scheme-toggle/blob/3474a80d81d89f1264be5d55652dc65b5aea68e2/javascripts/discourse/initializers/dark-light-toggle-hamburger.js#L56-L59

Can you link to your site here if possible? Is your instance up to date?

Hello,

I have an issue. After adding the theme, the toggle icons are not added in the hamburger menu. They dont even exist in bare code. Also you demo here the buttons dont work. meaning they dont switch between light and dark themes.

Anyone else having the same issue?

Can you check the dev tools console and see if anything shows up related to this? I am seeing the icons work fine on the demo site.

Here is the video:

My main issue is that on my forum, I don’t even see these options in hamburger menu:

You do not have the console tab open in your screen cast, so it is hard to see if any errors are taking place.

Have you made sure to follow each step in the original post on this topic?

at least 2 color scheme choices need to be enabled in your /admin/customize/colors area
A dark theme needs to be enabled at: /admin/site_settings/category/basic?filter=dark

And do you, as a user, have two color schemes selected, one for light, and one for dark, in your user preferences?

Hello,

Yes this was correctly executed. Today everything is showing correctly. This was due to cookies. It was odd that on other browsers (where I never visited the forum) it was showing missing as well. Now everything is correct. Thank you and sorry for the confusion I’ve caused.

Only thing is, all users including guests can see the toggle on header. But as an admin when I am logged-in, I cannot see the toggles. Is this intentional? Could this be server cache or something?

Hmm that’s interesting. Do you have a dark and light color scheme selected in your user preferences?

And are you using the theme that has the component installed?

I had to go to my profile and enable this option (Enable automatic dark mode color scheme) so it can appear on header. probably I was fidgeting around and missed that checkbox.

I love this component! :heart_eyes: But, I am having a little issue.

It looks like the component only works when the “Enable automatic dark mode color scheme” option is enabled. My issue occurs when the option is enabled, and when the system preference is set to dark mode (i.e., preferred color scheme: dark).

In the scenario above, when I try to switch to a light theme vie Preferences > Interface > Theme, nothing happens, which is fine with me. Presumably, since my system preference is already set to dark mode, switching to light mode in Discourse does not override it.

When I do the same with the Dark / Light Mode Toggle component, and if my theme preference in Discourse is set to Light, the toggle actually lets me switch to light mode (which is even better in my view) but the site logo on the header remains in dark mode and hard to see in light mode. When I look in the inspector, I see the element looks like this:

<div class="title"><a href="/" data-auto-route="true"><picture><source srcset="<link to image>" media="(prefers-color-scheme: dark)"><img src="<link to image>" id="site-logo" class="logo-big"></picture></a></div>

I noticed the media="(prefers-color-scheme: dark)" part although we are now in light mode set by the toggle.

I should add that the site logo ordinarily switches fine between light and dark mode when the “Enable automatic dark mode color scheme” option in Discourse is unchecked. But, this prevents the Dark / Light Mode Toggle from being displayed :man_shrugging:t2:

Also, if my theme preference in Discourse is set to Dark from Preferences > Interface > Theme, and my system preference is also dark, the toggle does not switch between light and dark—it always remains on the dark theme.

Ideally, I would prefer the Dark / Light Mode Toggle component to work the way it does now, but to make the site logo in the header follow the currently-active light/dark setting, not the user’s system preferred color scheme.

Same here! Did you find a solution?

I’m no frontend developer but I did some debugging:
When in dark mode, like my computer is set to, the HTML for the logo looks like this:

And the logo looks fine, with dark mode fully working. When toggling to light mode, the theme goes light but the logo disappears (dark logo remains).

This is what the HTML looks like:

There is an additional line, <source srcset="https://radixtalk.com/uploads/default/original/1X/19838ecb731d3f87d9db76c927e793ab2e159f1e.png" media="(prefers-color-scheme: dark)"> which “blocks” the correct logo from loading. If I remove that line with Inspect Element, and only leave <img src="https://radixtalk.com/uploads/default/original/1X/237090c67d33a1a38f9f031336dab420c4c4a37d.png" alt="RadixTalk" id="site-logo" class="logo-small" width="36">, the correct logo shows up.

I hope this info was useful.

I’m afraid not. I ended up changing the header background color in a way that switching the logo between light and dark mode no longer mattered :man_shrugging:t2:

Bumped into the same problem, hoping for a fix soon. Switching dark/light with my local device setting works fine and shows the correct light-logo.

EDIT: I noticed this bug only happens, when the actual device setting is set to dark, if the current device setting is light everything works as expected. Hope this helps.

Has anyone been able to look into this issue? I tried but this is a little too complicated for me at this point… :stuck_out_tongue:

Due to a refactor & implementation of how dark mode & light mode now work in core, this issue has arisen. It will take a good refactor of the code to get it working properly.

Sorry about this!

@jordan-vidrine - Any updates?
For some reason my toggle has stopped working all together. Not sure if it’s update related or something I’ve done.
Will keep troubleshooting though!
