Composer "Show" As A Sanity Check

I have found that when upgrading or installing Composer packages, it is always useful to do a quick sanity check by running:

$ composer show

This command will list out all the available packages you have installed for your project.

It has been particularly useful when running through a Laravel framework upgrade. If I just want to confirm that the correct pacakge for the upgrade was installed or if I am seeing some wonky behavior, I first check to ensure the installed packages are the correct version and what I am expecting to see.

When running the command (depending on your project) the list can get pretty long, but you can filter it by passing an argument to the command:

# Passing package provider and wildcard:
$ composer show laravel/*

# Command outputs:
laravel/breeze    v1.4.1  Minimal Laravel authentication scaffolding with Blade and Tailwind.
laravel/framework v8.60.0 The Laravel Framework.
laravel/tinker    v2.6.1  Powerful REPL for the Laravel framework.

# Passing provider name and package name:
$ composer show laravel/tinker

# Command outputs:
name     : laravel/tinker
descrip. : Powerful REPL for the Laravel framework.
