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 🙏

grunt-concurrent Build Status

Run grunt tasks concurrently

Running slow tasks like Coffee and Sass concurrently can potentially improve your build time significantly. This task is also useful if you need to run multiple blocking tasks like nodemon and watch at once, as seen in the example config.

This task is similar to grunt-parallel, but more focused by leaving out support for shell scripts which results in a leaner config. It also has a smaller dependency size and pads the output of concurrent tasks, as seen above.

Getting Started

If you haven't used grunt before, be sure to check out the Getting Started guide, as it explains how to create a gruntfile as well as install and use grunt plugins. Once you're familiar with that process, install this plugin with this command:

npm install grunt-concurrent --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-concurrent');

Tip: the load-grunt-tasks module makes it easier to load multiple grunt tasks.

Documentation

See the Gruntfile in this repo for a full example.

Just specify the tasks you want to run concurrently as an array in a target of this task as shown below.

Example config

This will first run the Coffee and Sass tasks at the same time, then the JSHint and Mocha tasks at the same time.

grunt.initConfig({
	concurrent: {
		target1: ['coffee', 'sass'],
		target2: ['jshint', 'mocha']
	}
});

grunt.loadNpmTasks('grunt-concurrent');
grunt.registerTask('default', ['concurrent:target1', 'concurrent:target2']);

Options

limit

Type: Number
Default: Number of CPU cores (require('os').cpus().length) with a minimum of 2

Limit of how many tasks that are run concurrently.

logConcurrentOutput

Type: Boolean
Default: false

You can optionally log the output of your concurrent tasks by specifying the logConcurrentOutput option. Here is an example config which runs grunt-nodemon to launch and monitor a node server and grunt-contrib-watch to watch for asset changes all in one terminal tab:

grunt.initConfig({
	concurrent: {
		target: {
			tasks: ['nodemon', 'watch'],
			options: {
				logConcurrentOutput: true
			}
		}
	}
});

grunt.loadNpmTasks('grunt-concurrent');
grunt.registerTask('default', ['concurrent:target']);

Note the output will be messy when combining certain tasks. This option is best used with tasks that don't exit like watch and nodemon to monitor the output of long-running concurrent tasks.
