Running a command with gulp to start Node.js server

PourMeSomeCode提出了一个问题：Running a command with gulp to start Node.js server，或许与您遇到的问题类似。

回答者PourMeSomeCode给出了该问题的处理方式：

gulp.task('server', function (cb) {
  exec('node lib/app.js', function (err, stdout, stderr) {
    console.log(stdout);
    console.log(stderr);
    cb(err);
  });
  exec('mongod --dbpath ./data', function (err, stdout, stderr) {
    console.log(stdout);
    console.log(stderr);
    cb(err);
  });
})

For future reference and if anyone else comes across this problem.

The above code fixed my problem. So basically, I found out that the above is its own function and therefore, doesn't need to:

.pipe

I thought that this code:

exec('start server', function (err, stdout, stderr) {

was the name of the task I am running however, it is actually what command I will be running. Therefore, I changed this to point to app.js which runs my server and did the same to point to my MongoDB.

EDIT

As @N1mr0d mentioned below with having no server output a better method to run your server would be to use nodemon. You can simply run nodemon server.js like you would run node server.js.

The below code snippet is what I use in my gulp task to run my server now using nodemon :

// start our server and listen for changes
gulp.task('server', function() {
    // configure nodemon
    nodemon({
        // the script to run the app
        script: 'server.js',
        // this listens to changes in any of these files/routes and restarts the application
        watch: ["server.js", "app.js", "routes/", 'public/*', 'public/*/**'],
        ext: 'js'
        // Below i'm using es6 arrow functions but you can remove the arrow and have it a normal .on('restart', function() { // then place your stuff in here }
    }).on('restart', () => {
    gulp.src('server.js')
      // I've added notify, which displays a message on restart. Was more for me to test so you can remove this
      .pipe(notify('Running the start tasks and stuff'));
  });
});
