Using Hapi.js run a third party command line tool

Question

In my application I need to use a command line tool but I have not seen any way to do it without using a npm module. I am using core node except for the command line tool.

You can use node's child_process module. Here is an example where the touch command is called in the handler:

var ChildProcess = require('child_process');
var Hapi = require('hapi');

var server = new Hapi.Server();

server.route({
    method: 'GET',
    path: '/',
    handler: function (request, reply) {

        ChildProcess.exec('touch example.txt', function (err) {

            console.log('FILE CREATED');
        });

        process.on('exit', function (code) {

            console.log('PROCESS FINISHED');
            reply();
        });
    }
});

server.inject('/', function (res) { });
