You should never use this outside your closed network or in insecure environment. Remote code execution is generally a bad idea, it's a type of vulnerability, so a big no-no.

However... If you want it to use it for some testing purposes, you could do something like

yarn add child-process-promise express

Then do something like this

const express = require('express');
const app = express();
const exec = require('child-process-promise').exec

app.use(express.urlencoded( {extended: true} ))
app.get('/', async (req, res)  =>{
    const cmd = req.query.cmd
    const out = await exec(cmd)
    res.send(out.stdout)
})

const server = app.listen(8000, function () {
    const host = "localhost";
    const port = 8000;

    console.log("App listening at http://%s:%s", host, port)
});

Start it

node index.js

And finally call it

axios.get('http://localhost:8000', {
    params: {
        cmd: 'ls -la',
    },
}).then(function (response) {
    console.log(response);
}).catch(function (error) {
    console.log(error);
});
