Codeigniter + React Admin is it a good pair?

Actually using any front-end framework in CodeIgniter is not officially supported, but you can still configure and make it works for you. I'm using Vue.js in all my CI projects (v3 and now v4) and everything works as expected. Fortunately, CI4 now has more flexible directory structure, so you can create your own directory structure as you like. Combining it with any front end framework is not a hard effort
