Redirects in React Router v6

An important part of "routing" is handling redirects. Redirects usually happen when you want to preserve an old link and send all the traffic bound for that destination to some new URL so you don't end up with broken links.

The way we recommend handling redirects has changed in React Router v6. This document explains why.

Background

In React Router v4/5 (they have the same API, you can read about why we had to bump the major version here) we had a <Redirect> component that you could use to tell the router when to automatically redirect to another URL. You might have used it like this:

What is Weenie Hut General Messaging Protocol (WHGMP)?

WHGMP is a message protocol which uses 2 Discord bots and 9 channels.

(pssst... click here to see a more detailed project, with the main bot in addition to the messaging protocol)

How does it work?

WHGMP uses the read/unread badge* in a channel to represent a bit (unread = 1, read = 0). By using 8 channels, one byte can be stored.

The sender waits for a message from the user, then begins to send messages to the data channels. After storing a single byte, a message is sent to the "clock" channel, letting the receiver know to check the read/unread status. Based off of that, a single byte is constructed. When a null-byte is received, the resulting string is printed.

I wanted to be able to detect when Dark mode was turned on or off in my Go program so I can swap icons in my tray app on Windows so I wrote this.
When Dark Mode is turned on or off, it writes to a pair of registry keys, both of which Windows allows you to set independently in Settings > Personalization > Colors.

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize  

SystemUsesLightTheme  DWORD 0 or 1 // Changes the taskbar and system tray color  
AppsUseLightTheme     DWORD 0 or 1 // Changes app colors  

Mine is a tray app, so I am monitoring the first one. I did not want to just periodically poll the registry key and I wanted to be able to react immediately when the registry key is changed, so I am using the win32 function RegNotifyChangeKeyValue in advapi32.dll to tell the OS to notify my app so I can swap out the icon for a color-appropriate one.
I start the monitor function in main, which loads the RegNotifyChangeKeyValue function from advapi32 and starts a gorouti

I wanted to be able to detect when Dark mode was turned on or off in my Go program so I can swap icons in my tray app, but the Apple-blessed methods all use Swift and ObjectiveC. To work around this I figured out the following:

• When dark mode is set, a property called "AppleInterfaceStyle" is set to "Dark" for the user.
• When dark mode is disabled, that property is removed.
• You can see this by running "defaults read -g AppleInterfaceStyle"

// Dark Mode On  
defaults read -g AppleInterfaceStyle
