I just created a new react app using create-react-app. when I tried access the app from another pc on the same lan, it seems to be loading but doesn't shows up.
I am able to view the static files with no problem.
Thanks for your help.

Update: Tried on other lan network and it's working! what can be the reason it doesn't work on the first lan?

See the Create-React-App docs:

HOST:
By default, the development web server binds to localhost. You may use this variable to specify a different host.

Set the HOST environment variable (in .env or in your shell) to 0.0.0.0 to bind to every address and you should be off to the races.

You have to make sure that the port 3000 is open on your machine (or any other that you use).

In addition, you can try to serve application on 0.0.0.0 host instead of localhost.

To access your localhost react dev server on another puter on the same LAN you need to know the LAN IP of the host puter where the react dev server is running. On mac you can find the ip here: System Preferences > Network > Advanced > TCP/IP. It is either the IPv4 or IPv6 address.

Just replace localhost with the IP address when accessing the server with the other puter.

For example: localhost:3000 > 192.168.1.179:3000
