Question 1

How to use get-port-cli to find an open port for a web server?

Accepted Answer

Run `get-port 3000` or specify a preferred port like 3000; it will return an available port, such as 9090 if 3000 is taken, which you can assign to your server. This integrates easily into startup scripts by capturing the output.

Question 2

get-port-cli vs netstat for checking port availability?

Accepted Answer

get-port-cli is faster and simpler for finding an unused port, while netstat provides detailed listing of all used ports but requires parsing. Use get-port-cli for automation and netstat for diagnostics or manual checks.

Question 3

Can get-port-cli check ports on a remote server?

Accepted Answer

No, get-port-cli only checks ports on the local host specified via the `--host` option, such as 127.0.0.1. For remote servers, you'd need to run it on that machine or use other tools like SSH.

Question 4

What happens if no preferred port is available in get-port-cli?

Accepted Answer

If all preferred ports are taken, get-port-cli automatically selects a random available port from the system, as shown in the example `$ get-port 80` returning `9090` when 80 is occupied.

Question 5

Is get-port-cli cross-platform?

Accepted Answer

Yes, it works on any platform with Node.js installed, including Windows, macOS, and Linux. However, port availability might vary based on the host system's network configuration.

Question 6

How to integrate get-port-cli into a bash script?

Accepted Answer

Assign the output to a variable, e.g., `PORT=$(get-port 3000)`, then use it in your script to start services. This leverages its simple output for seamless automation.
