Directly use Batch file output as nodejs variable without using txt

Question

what I'm doing now is make a txt file using batch file output

@echo off
set fname=Logan
set lname=Anderson
set gender=male
echo %fname%>>1.txt
echo %lname%>>1.txt
echo %gender%>>1.txt

Then read that txt using nodejs and use those as nodejs input, but what I want is if it is possible to use batch file output as nodejs input without using this txt file, directly call "nodejs compiled project using pkg" exe file with variables from batch

such as, In batch file

@echo off
set fname=Logan
set lname=Anderson
set gender=male
start "" "mycompiledproject.exe" "%fname%" "%lname%" "%gender%"

Answer 1

To use command line arguments in node, you need to use process.argv (here is the documentation for it: https://nodejs.org/docs/latest/api/process.html#process_process_argv)

So in your case, your node.js code should look something like this:

const process = require('process');

process.argv.forEach(function(value, index, array){
    //value will be the argument(s), index is there position,
    //and array is the entire array they are in. this function 
    //is called for each value.
});

once you turn this to exe, it should run in your batch just fine.
