Not really every single one, because straight.el installs dependencies automatically.

Here's the file I went through during this recording. Some things may have changed slightly since the time of recording. Save this file in ~/.emacs.d/init.el to reproduce my exact Emacs configuration that I use at home and at work.

;;; init.el ---  This is Tiago's init.el file
;;; Commentary:
;;; Thanks to everyone that curates Emacs packages.

;;; Code:
