Automatic Night Mode Component

Following up the discussion here:

I made a theme component that will automatically switch to night theme based on user preferences. It’s currently work on a per-browser basis.




Add this component to each theme installed.

Known Issues

  • I’ve received a report of the component making all navigation cause full reloads. Upon navigating between different pages every click caused a full refresh instead of an in-app navigation. I have not been able to reproduce this, so please post reproduction steps if you run into this.

Feedback is welcome and thanks to Discourse team for sponsoring this work :slight_smile:


Nice theme component. But I can’t choose a time range for activation. It seems the field is for US time zones only?

Is it possible to add macOS Light/Dark mode detection?

I’m sure it’s local (device) time.

There is another theme for that:


I can’t enter my local time manually. Nothing happens.

Thanks for this hint! I’ve had this in my bookmarks before :see_no_evil:

Unfortunately, it doesn’t work right now. I need to some troubleshooting first…


Can this theme component be combined with this one?

That way users could override the automatic dark mode, when desired

Yes, you can but it might lead to unexpected behavior.

It seems, this component is broken. Whenever I enable it in my profile settings and reload the page, the checkmark in the box disappears and it’s disabled

I believe @pmusaraj is working on something even more automatic than this.


Core has a similar feature now based on the device’s dark mode UI, please see Automatic Dark Mode color scheme switching.
