“Participating in open source has been one of the most rewarding experiences of my career. The feeling of sharing something I’ve created, and hearing that others are using it in their applications is incredible. But writing and managing an open source project is challenging. I want to help you get started with open source or improve your current projects with some of the things I’ve learned by publishing and maintaining over 60 npm packages.”
~Kent C. Dodds

By coding along with us for this workshop you’ll:

  • Learn how to set up a new project locally and on GitHub for development
  • Learn how to configure npm for publishing the project to the npm registry
  • Learn how to transpile the source with babel
  • Learn how to add unit tests and code coverage
  • Learn how to add CI (with Travis CI) to run tests automatically and report coverage stats to
  • Learn how to automate releases with semantic-release
  • Learn how to distribute a browser build with webpack
Your ticket includes the full workshop (online or in-person), immediately available replay videos, plus a complimentary 6 month membership to watch all our video courses (a $234 value)

How We'll Spend the Day

We've already held over 50 workshops holding thousands attendees in-person and online. In this time we've discovered ways to schedule the day so it goes smoothly and efficiently.

Regardless if you're in-person or participating with us online you'll have the full ability to replay things you missed, get your questions answered LIVE and interact with the teacher throughout the day.

We’ll get started by giving an overview of what we’re going to build, then we’ll get our blank slate going with a package.json. We’ll talk about the significance of this file and the various properties we’ll use to help us with the distribution and management of our module and its dependencies.

Then we’ll add the tooling needed for testing our library and adding code coverage. This is something that’s really important to get working early on in the project, so we’ll get it done early.

Then we’ll jump into setting up the tooling for transpiling our source code from ESNext to ES5 so we distribute code that can be consumed by people delivering to older environments (like old Node or browsers).

Then we’ll add the tooling we need to distribute a browser version of our library so people can consume our library in the context of a browser (without having to bundle it themselves).

As contributions to our library grows, it’ll be important to be able to check that the contribution passes our unit tests automatically without having to pull down every pull request to test it locally. So we’re going to add continuous integration with TravisCI to automatically run our tests and report the code coverage reports to

With this infrastructure set up, we’ll then add semantic-release to automate releases of our library. This will help us reduce a great amount of human error associated with the release process.

We’ll wrap up by providing useful links and resources about how to maintain the project in the long term.

The Price

The price for attending this full day workshop is simply the cost of becoming a monthly ($39) member. If you have already attended one, you know this is a tremendous value. If you haven’t, you may be wondering if it’s truly worth becoming a member.

Browse through just a few of the testimonials and you’ll see that people RAVE over these workshops. They’re unique and provide an experience and education you simple cannot find anywhere else.

You’re getting access to some of the brightest, most highly sought after experts in the world, covering topics very few people discuss in detail. Many attendees report learning more in this full day workshop than they did about a particular topics in the past 1-2 years combined.

Combine that with access to thousands of unique, high quality videos in our membership area with 500 hours of in-depth training from world renowned experts and you’ll see why this is a bargain.

  1. These workshops are different from any others you’ve attended. They cover everything, from the basics to advanced material. All of which are available for replay so you can go back and review as your skill grows.

  2. We get a lot of people saying they are scared to join… until it was over. Then they brag about how much of an amazing value they got for the price.

  3. You’re also getting videos of the workshop, plus ALL other workshops we’ve recorded, instantly!

Is This Workshop For Me?

This is for anyone who writes code they want to use again for themselves in another project or share with others. If you’ve never published a library before, this will be great for you. If you’ve published libraries, but want to see how you can improve your tooling and automate processes, this will be really valuable.


You should be familiar with JavaScript, but a deep knowledge of it is not necessary as most of the time will be spent on tooling around the library, rather than developing the library itself. You should have a basic understanding of what npm is and its role in JavaScript development. You’ll need to have the following installed/setup on your laptop before the class:

You'll Either LOVE This Workshop Or You Don't Pay. Period.

Our attendees are ecstatic by the high-quality, relevant content they receive at these workshops.

We cover everything in explicit detail (and the things we miss are covered by answers to YOUR questions) from basic to advanced tactics you can start working with the very same day. We don't want you to miss out on this opportunity because you've been to less-than-stellar workshops in the past. We promise you, ours are very unique.

That's why if you attend the workshop and aren't absolutely thrilled with the content… if you don't think it's worth the admission price… We refuse to accept your money. We will more than gladly issue you a full refund, so you risk nothing.

We're very specific about what you're getting here and have ran lots of workshops… so we've almost never have requests for refunds (99.8% satisfaction rate).

What Past Attendees Are Saying

"Superb presentation from a genuine domain expert. I learned a ton today."

Steve Jakubowski

"Keep up the good work. I've attended a lot of online workshops, and they are very shallow and unpractical. Most of the time, online people are treated as second class, but still paying citizens. Here we get all the content and get to participate as well (if only there was a way to get those cookies...)."

Adrian Murillo

"The class was great. It was really cool to get a bunch of links to example code to look at during the presentation and after the class."

Nate Yourchuck

"Good location and facility. Great technology for capture, presentation layout and video streaming. Really excellent being able to view the videos afterwards. It takes away the sense of having to absorb everything immediately or else lose it into the ether. It was fun. What more can you ask for?"

Laurence Bates

"Really well run...loved the communication pre-event. Very impressed with everything...this was my first online conference purchase, but I would definitely consider doing it again."

Jeff Sims

"I really enjoyed the online workshop experience. It is much better than just watching videos. I was able to participate in the conversations and benefit from other folks' questions."

Dana Greenberg

"You guys did a really great job! I cannot say enough good things about the experience."

Richard Ranke

"Everything was first class: excellent instructor, material, video, moderator, audio. Thank you!"
