How can I run multiple npm scripts in parallel?

Question

In my package.json I have these two scripts:

  \"scripts\": {
    \"start-watch\": \"nodemon run-babel index.js\",

My solution is similar to Piittis', though I had some problems using Windows. So I had to validate for win32.

const { spawn } = require("child_process");

function logData(data) {
    console.info(`stdout: ${data}`);
}

function runProcess(target) {
    let command = "npm";
    if (process.platform === "win32") {
        command = "npm.cmd"; // I shit you not
    }
    const myProcess = spawn(command, ["run", target]); // npm run server

    myProcess.stdout.on("data", logData);
    myProcess.stderr.on("data", logData);
}

(() => {
    runProcess("server"); // package json script
    runProcess("client");
})();
