CodeIgniter Expenses - pet project for beginners

1. The main.js and main.css files are always accessible from browser, unlike bootstrap (copied from /vendor/).
I did not complicate it - it is possible to move the frontend to a separate folder (for React, SCSS). Then it was possible to create a Publisher.
How did you plan to generate these files?

2. See https://github.com/neznaika0/codeigniter...toasts.php

PHP Code:

// key "validation" for flashes
return redirect()->back()->withInput()->with('validation', $this->validator->getErrors());

// or Bootstrap keys 'success', 'danger', 'warning', 'info'
return redirect()->back()->with('success', lang('Expense.created')); 


Validation is shown first, then the others messages.
