How to open a create-react-app from another computer connected to the same network?

Question

I am using create-react-app and hosting in its default port localhost:3000 and want to access this from another device on the same net

Answer 1

Simply run HOST=0.0.0.0 npm run start.
Afterwards open the url from another device on the network.

In your case, 192.168.0.5:3000 would work.
