i have a web app in laravel 5.4 and node.js
i want to make this live on server
which web hosting is best for this
is there any free web hosting for this??
Sorry, but your question is maybe a little bit too broad to answer well.
I'm guessing that if you have the technical skill to make a laravel and node.js app then you should also be able to figure out what to do when you start hosting it, so I'll assume that you're just looking for advice for which service provider to use.
There is no reliable free hosting I am aware of, so you will probably need to look into a service like Heroku, Digital Ocean or Linode to run your server.
I can't vouch for the quality but if you want an easy solution perhaps you could start here: https://forge.laravel.com/
Hosting will depend on your app architecture and what it is doing. Especially when you have two server side technologies running you're probably going to want a virtual private server.
