Execute a Command Line Binary With Node.Js

Run a binary from Node.JS and relay the behavior exactly on the console, including prompts

You can use 'inherit' for the stdio option of spawn:

const spawn = require( 'child_process' ).spawn;
spawn( '/path/to/binary', [], { stdio: 'inherit' } );

Execute and get the output of a shell command in node.js

This is the method I'm using in a project I am currently working on.

var exec = require('child_process').exec;
function execute(command, callback){
    exec(command, function(error, stdout, stderr){ callback(stdout); });
};

Example of retrieving a git user:

module.exports.getGitUser = function(callback){
    execute("git config --global user.name", function(name){
        execute("git config --global user.email", function(email){
            callback({ name: name.replace("\n", ""), email: email.replace("\n", "") });
        });
    });
};

How to execute node command in a node app?

run it sequentially with execSync

const execSync = require('child_process').execSync;

//...
switch (arg) {
    case "React App":
        console.log(`npx create-react-app ${projectName}`);
        execSync(`npx create-react-app ${projectName}`);
        console.log(`cd ${projectName}`);
        execSync(`cd ${projectName}`);
        console.log(`npm start`);
        execSync(`npm start`);
        break;
    case "Next App":
        console.log(`npx create-next-app@latest ${projectName}`);
        execSync(`npx create-next-app@latest ${projectName}`);
        console.log(`cd ${projectName}`);
        execSync(`cd ${projectName}`);
        console.log(`npm dev`);
        execSync(`npm dev`);
        break;
}

Execute bash script via Node.js and include command line parameters

The second parameter in spawn is an array of arguments to pass to the command. So I think you almost have it but instead of concating the params to the path pass them in as an array:

var spawn = require('child_process').spawn;
var params = ['pathToScript','run', '-silent'];
spawn('bash', params, {
    stdio: 'ignore',
    detached: true
}).unref();
