node daemon won't start with process.stdin.setRawMode(true)

Question

I am running a node server daemon but I keep running into this error.

When I run my bash strip to test the application I get TypeError: process.stdin.setRawMode is not a function.

Can you help me find a way I can use keyboard input with this node application running in the background?

I have tried giving my bash script permissions chmod 777 x.sh & chmod 755 x.sh

setRawMode() is only available when the input is provided by a TTY and not like yours as direct stream from stdin.

Use this to check what stream you have:

if (process.stdin.isTTY) {
    process.stdin.setRawMode(true);
}
