Essential Laravel Deployment Checklist

You just deployed your Laravel app and got a blank white screen. Zero errors.

Just silence. Here's what actually happened. You forgot your environment file

exists. Laravel can't connect to your database because your dot env is still pointing

to localhost. Your app key is missing so sessions are breaking silently. Then there's cache.

Old routes cached from development are still running even though you changed everything.

Config cache is holding dead values. You clear cache once but route cache is still there laughing

at you. Now class not found errors. You added a new controller but composer

didn't autoload it yet. One command fixes it but you spent an hour googling.
