What are the challenges you faced to host you Laravel application on shared hosting ?

Depending with the host - for some you may not have ssh access - so you have to be creative if you need to run terminal commands. For this I host with namecheap and have access to terminal

Had to move arround the public folder so public_html contains the contents in the public folder of laravel - very many blog posts exists on this

I think those two are the ones I have faced personally.

Here is a good walk through of how to use laravel on a shared host. There are certain things that must be done in order for laravel to work as expected on a shared host. https://www.5balloons.info/hosting-laravel-5-5-project-on-shared-hosting-hostgator/

A lot so I switched to using digital ocean instead

i dont see why people r still using shared hosting? DO the cheapest is only $5 which is same as the monthly cost of a shared host..
