Running node-inspector and node-debug with npm run

Question

How to run two script at once with npm run ? First of all I know grunt or gulp but I want to make it without another js modules. To make this I have this script:

"scripts": {
  "start": "node ./node/www",
  "nodemon": "./node_modules/.bin/nodemon node/www.js -i './e2e-tests/**' -i './node_modules/**' -i '.idea/**' -i './node/log/**' -w './node/server/**/*' -V -L",
  "nodeInspector": "./node_modules/.bin/node-inspector --save-live-edit=true",
  "debug": "node-debug ./node/www.js",
  "ins": "npm run nodeInspector & npm run debug"
}

I want to run with npm run ins but it only fires node-inspector.

Answer 1

It is not possible to run both commands. They each need their own console

Answer 2

If node-debug comes from node-inspector package, then you don't need to start a new node-inspector instance, node-debug will start it automatically for you.

This is what node-debug performs under the hood ( source code ):

1. Run node-inspector.
2. Run the supplied script in debug mode
3. Open the user's browser, pointing it at the inspector.

In fact, running both node-inspector and node-debug will not work as intended, as the second node-inspector instance won't be able to attach to the same port where the first instance already listens.

I couldn't make it happen on one line that's why I changed to grunt with concurrent:

module.exports = function(grunt) {
    grunt.initConfig({
        concurrent: {
            options: {
                limit: 3,
                logConcurrentOutput: true
            },
            debug: {
                tasks: ['node-inspector', 'nodemon:debug'],
                options: {
                    logConcurrentOutput: true
                }
            }
        },
        nodemon: {
            dev: {
                script: "node/www.js",
                options: {
                    ignore: ['node/public/**'],
                    callback: function (nodemon) {
                        nodemon.on('log', function (event) {
                            console.log(JSON.stringify(event));
                        });

                        // opens browser on initial server start
                        nodemon.on('config:update', function () {
                            console.log("nodemon config:update oldu");
                            // Delay before server listens on port
                            setTimeout(function() {
                                require('open')('http://localhost:3000');
                            }, 1000);
                        });

                        // refreshes browser when server reboots
                        nodemon.on('restart', function () {
                            // Delay before server listens on port
                            setTimeout(function() {
                                //require('fs').writeFileSync('.rebooted', 'rebooted');
                            }, 1000);
                        });
                    }
                }
            },
            debug: {
                script: './node/www.js',
                options: {
                    ignore: ['node/log/*.log','node/public/**','node/views/**','doc/**','e2e-tests/**','.idea'],
                    callback: function (nodemon) {
                        nodemon.on('log', function (event) {
                            console.log("Nodemon debug callback fonksiyonu nodemon.onLog olayı");
                        });

                        // opens browser on initial server start
                        nodemon.on('config:update', function () {
                            console.log("Nodemon debug callback fonksiyonu nodemon.onConfig:Update olayı");
                            // Delay before server listens on port
                            setTimeout(function() {
                                require('open')('http://localhost:3000');
                                require('open')('http://localhost:1337/debug?port=5858');
                            }, 1000);
                        });

                        // refreshes browser when server reboots
                        nodemon.on('restart', function () {
                            console.log("Nodemon debug callback fonksiyonu nodemon.onRestart olayı");
                            // Delay before server listens on port
                            setTimeout(function() {
                                //require('fs').writeFileSync('.rebooted', 'rebooted');
                            }, 1000);
                        });
                    },
                    nodeArgs: ['--debug'],
                    watch: ['Gruntfile.js', 'node/server', 'package.json']
                }
            }
        },
        'node-inspector': {
            custom: {
                options: {
                    'web-port': 1337,
                    'web-host': 'localhost',
                    'debug-port': 5857,
                    'save-live-edit': true,
                    'no-preload': true,
                    'stack-trace-limit': 4,
                    'hidden': ['node_modules']
                }
            }
        }
    });

    require('matchdep').filterDev('grunt-*').forEach(grunt.loadNpmTasks);

    // Çalışması test edildi ve iki pencerede hem test hem uygulama açıyor.
    grunt.registerTask('nodemon-debug', ['concurrent:debug']);

};

I managed to run node-inspector and nodemon from a script using concurently

https://www.npmjs.com/package/concurrently

"dev": "npm install && concurrently \\"node-inspector --web-port 9090\\" \\"nodemon --debug .\\""
