Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

gulp-nodemon

Published on NPM as gulp-nodemon-tempfix until https://github.com/JacksonGariety/gulp-nodemon/pull/91 is merged

it's gulp + nodemon + convenience

Install

$ npm install --save-dev gulp-nodemon

Usage

Gulp-nodemon looks almost exactly like regular nodemon, but it's made for use with gulp tasks.

nodemon([options])

You can pass an object to gulp-nodemon with options like you would 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.

gulp.task('start', function () {
  nodemon({
    script: 'server.js'
  , ext: 'js html'
  , env: { 'NODE_ENV': 'development' }
  })
})

Synchronous Build Tasks

NOTE: This feature requires Node v0.12 because of child_process.spawnSync.

Nodemon is powerful but lacks the ability to compile/cleanup code prior to restarting the application... until now! Most build systems can never be complete without compilation, and now it works harmoniously with your nodemon loop.

{ tasks: [Array || Function(changedFiles)] }

If you want to lint your code when you make changes that's easy to do with a simple event. But what if you need to wait while your project re-builds before you start it up again? This isn't possible with vanilla nodemon, and can be tedious to implement yourself, but it's easy with gulp-nodemon:

nodemon({
  script: 'index.js'
, tasks: ['browserify']
})

What if you want to decouple your build processes by language? Or even by file? Easy, just set the tasks option to a function. Gulp-nodemon will pass you the list of changed files and it'll let you return a list of tasks you want run.

nodemon({
  script: './index.js'
, ext: 'js css'
, tasks: function (changedFiles) {
    var tasks = []
    changedFiles.forEach(function (file) {
      if (path.extname(file) === '.js' && !~tasks.indexOf('lint')) tasks.push('lint')
      if (path.extname(file) === '.css' && !~tasks.indexOf('cssmin')) tasks.push('cssmin')
    })
    return tasks
  }
})

Events

gulp-nodemon returns a stream just like any other NodeJS stream, except for the on method, which conveniently accepts gulp task names in addition to the typical function.

.on([event], [Array || Function])

  1. [event] is an event name as a string. See nodemon events.
  2. [tasks] An array of gulp task names or a function to execute.

Example

The following example will run your code with nodemon, lint it when you make changes, and log a message when 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']
          , tasks: ['lint'] })
    .on('restart', function () {
      console.log('restarted!')
    })
})
