Declarative Package Management With Homebrew

Homebrew provides declarative package management through the brew bundle command with the --cleanup flag.

If a Brewfile contains packages:

cask "firefox"
cask "ghostty"
cask "proton-mail"
cask "zed"
cargo "cargo-audit"
cargo "cargo-nextest"
cargo "cargo-watch"

When:

brew bundle install --cleanup --file=Brewfile

Then all packages declared in the file will be installed. The --cleanup flag ensures that packages removed from the Brewfile are also uninstalled from your system.
