I just want to call an external exe from a nodejs-App. This external exe makes some calculations and returns an output the nodejs-App needs. But I have no idea how to make the connection between nodejs and an external exe. So my questions:
Nodejs shall wait for the output of the external exe. But how does nodejs know when the exe has finished its processing? And then how do I have to deliver the result of the exe? I don't want to create a temporary text-file where I write the output to and nodejs simply reads this text-file. Is there any way I can directly return the output of the exe to nodejs? I don't know how an external exe can directly deliver its output to nodejs. BTW: The exe is my own program. So I have full access to that app and can make any necessary changes. Any help is welcome...
child_process
module.Code will look like this
var exec = require('child_process').exec;
var result = '';
var child = exec('ping google.com');
child.stdout.on('data', function(data) {
result += data;
});
child.on('close', function() {
console.log('done');
console.log(result);
});
