/*
 * Inspired by Dan Abramov's "Making setInterval Declarative with React Hooks",
 * this is a custom hook for debouncing a callback (e.g. for click handlers) such
 * that a callback will not be fired until some delay has passed since the last click.
 * The callback will automatically be updated with the latest props and state on every
 * render meaning that users don't need to worry about stale information being used.
 *
 * See https://overreacted.io/making-setinterval-declarative-with-react-hooks/ for the
 * original inspiration.

On macOS:

$ brew install golang
$ go get github.com/cloudflare/cloudflared/cmd/cloudflared
$ cd ~/go/src/github.com/cloudflare/cloudflared/
$ env GOOS=linux GOARCH=arm GOARM=5 make cloudflared
$ scp cloudflared pi@pi.hole:

Then you can follow the instructions from https://docs.pi-hole.net/guides/dns-over-https/#arm-architecture-raspberry-pi
