如何在服务器上全局安装 Node.js 命令行脚本？

Question

As a prototype, I've written a simple Node.js command-line script which loads a .txt file and outputs the contents. I've read many articles which suggest that Node.js scripts are usually executed via the command-line and should be installed globally , so that's the direction I've taken, even if there are other techniques.

For the sake of this query, my globally installed command is called my-prototype .

This all works fine on the desktop but I intend to host this prototype on a server, using Express.

How do I globally install my-prototype on the server and, if that's possible, will I be able to execute it in the same way as in my local tests, as a child process?:

const { execSync } = require('child_process')
const output = execSync(`${process.execPath} my-prototype`)
console.log(output.toString())

I'm not entirely sure that globally installing command-line scripts is for use on a server and wonder whether that's for desktop use only.

If you need just output the contents , then you do not need a console, or rather: you only need it once, to run nodejs

const fs = require('fs');

const express = require('express');
const app = express();

//

app.get('/', async(req, res)=>{
    let fileContains = fs.readFileSync('./package.json', 'utf8');
    try{
        fileContains = JSON.parse(fileContains);
    }catch(e){}
    res.json(fileContains);
});

//

app.listen(80);
