gulp-nodemon

gulp-nodemon

A gulp-friendly nodemon wrapper that restarts your app as you develop, and keeps your build system contained to one process.

Perfect for development.

Usage

nodemon([options])

You can pass an object to gulp-nodemon with options specified in nodemon config.

Example below will start server.js in development mode and watch for changes, as well as watch all .html and .js files in the directory.

{
  script: 'server.js'
, ext: 'js html'
, env: { 'NODE_ENV': 'development' }
}

gulp-nodemon returns a stream just like any other NodeJS stream, except for the on method, which conveniently takes gulp task names to execute.

.on([event], [tasks])

1. [event] is an event name as a string. See nodemon events. (gulp-nodemon also provides a new event, 'change', which fires before the server restarts so that you can run your compile tasks all within the same gulp process.)
2. [tasks] A gulp task name, array of gulp task names, or a function to execute.

--debug

You can also pass the debug flag to nodemon through the nodeArgs option

Example below will start server.js in development with --debug flag.

{ 
  script: 'app.js', 
  ext: 'js html', 
  env: { 'NODE_ENV': 'development' } , 
  ignore: ['./build/**'], 
  nodeArgs: ['--debug'] 
}

You can also specify a custom debug port:

nodeArgs: ['--debug=9999']

Example

The following example will run your code with nodemon, lint it when your it change, then log a message when it nodemon runs it again.

// Gulpfile.js
var gulp = require('gulp')
  , nodemon = require('gulp-nodemon')
  , jshint = require('gulp-jshint')

gulp.task('lint', function () {
  gulp.src('./**/*.js')
    .pipe(jshint())
})

gulp.task('develop', function () {
  nodemon({ script: 'server.js', ext: 'html js', ignore: ['ignored.js'] })
    .on('change', ['lint'])
    .on('restart', function () {
      console.log('restarted!')
    })
})
