Connect to localhost:3000 from another computer | expressjs, nodejs [duplicate]
Given that the port is bind to any IP address other than 127.0.0.1 (localhost), you can access it from any other system.
To view your IP addresses, use ipconfig (Windows) or ifconfig (Linux) command.Find out the IP which is in the same network as the "other system" from which you want access.Then access it like, for example: 172.16.0.12:3000.
PS: Remember to include the port 3000 even when accessing it through another system. Also, hostnames may be used in place of IP addresses, if configured.
