I'm using node.js in my server side. Now I wanna run some binary file piled from a .c code, how to do that?

I've already tried var obj = new ActiveXObject("WwScript.Shell"); obj.run("myBinary");

But doesn't work... Thanks a lot!

• javascript
• node.js

• I think you're looking for child_process.exec. – Jared Farrish Commented Feb 12, 2012 at 5:13

var sys = require('sys')
var exec = require('child_process').exec;
exec("/path/to/your/Binary", function(error, stdout, stderr) { sys.puts(stdout) });

Update: It seems that sys module is is deprecated, use util instead as @loganfsmyth mentioned.

var exec  = require('child_process').exec,
    child;

child = exec('/path/to/your/Binary',
  function (error, stdout, stderr) {
    console.log('stdout:', stdout);
    console.log('stderr:', stderr);
    if (error !== null) {
      console.log('exec error:', error);
    }
});

The below code snippet from codegrepper. worked for me :)

const { exec } = require("child_process");    
    exec("ls -la", (error, stdout, stderr) => {
        if (error) {
            console.log(`error: ${error.message}`);
            return;
        }
        if (stderr) {
            console.log(`stderr: ${stderr}`);
            return;
        }
        console.log(`stdout: ${stdout}`);
    });
