php artisan key:generate
is a command that sets the APP_KEY
value in your .env
file. By default, this command is run following a composer create-project laravel/laravel
command. If you use a version control system like git
to manage your project for development, calling git push ...
will push a copy of your Laravel project to wherever it is going, but will not include your .env
file. Therefore, if someone clones your project using git clone ...
they will have to manually enter php artisan key:generate
for their app to function correctly.
So, TL:DR the only time you need to call php artisan key:generate
is following a clone
of a pre-created Laravel project.
Side note: If you try to run a Laravel project with your APP_KEY
set to SomeRandomString
(which is the default in your .env.example
file, you will actually get an error:
No supported encrypter found. The cipher and / or key length are invalid.
