A place for code & great experiences

Nordic.js will take place at Magasin 9, an international venue for music, art and food – located in a harbor, just 10 minutes from the city centre.

Nordic.js has been one of the warmest most welcoming conferences I have ever attended. Speakers and content were excellent, and the venue was awesome. Can't wait to be back.

Claudia Hernández, 2017

Make new friends

With over 1000 developers, designers and creatives descending to Stockholm for the event, and both structured and informal networking sessions provided, it’s a brilliant opportunity for you and your team to forge new professional contacts and make new friends.

World class speakers

Nordic.js is a single track conference with 8-10 talks per day by internationally renowned speakers as well as rising stars. Previous speakers include names like Douglas Crockford, Alice Bartlett, Tom Dale, Soledad Penadés, Bert Belder & Jake Archibald.

Are you interested in speaking at Nordic.js? Or do you know someone that would give a really interesting talk? In both cases, don’t hesitate to send us a proposal or suggest a speaker.

Build dumb sh*t

We tend to see our jobs and our work as developers as the pursuit to help the world and build useful things for other people because that's what we are thought.

When we learn something we make to-do lists, we make useful things. In this talk I am gonna try and show you the value of making dumb things, making useless things.

Happily Ever After: A CRDT Fairy Tale

CRDTs. You feel like you’ve heard the acronym before. It sounds important and interesting, but what are they? How do they work? And why should you care? We’ll dig in to some specifics and use Atom’s teletype package as an example to understand what they’re all about.

In this broken down, accessible-to-all-experience-levels talk, you’ll leave being able to show off to your friends and colleagues by answering “what are CRDTs (conflict-free replicated data types)?” With more than just a shrug.

No Return: Moving beyond transactions in software and in life

After 20 years building a successful software development career, my life fell apart. Deconstructing how it happened revealed surprising parallels between how I had approached building a career and family, and how I had designed software. At the root of all was an insidious misconception: one that had hobbled both the growth of my software systems, and my potential for personal fulfillment.

Join me for an honest, sometimes raw reflection on two decades of software development and life. We’ll examine how personal philosophy impacts software design---and vice-versa. We’ll encounter the “transactional fallacy”, and how it can poison our attempts to build resilient systems. And we’ll explore how a graceful, process-oriented mindset can lead to both better code and a more joyful life.

In his 20-year software development career, Avdi Grimm has worked on everything from aerospace embedded systems to enterprise web applications. He’s a consulting pair-programmer, the author of several popular Ruby programming books, and a recipient of the Ruby Hero award for service to the Ruby community. Since 2011 he has been teaching developers how to work more effectively (and have fun doing) it at

He spends his theoretical spare time hanging out with his kids, hiking the Smoky Mountains, and dancing to oontz-oontz music.

Mind-Reading with Adaptive and Intelligent User Interfaces

What if you could predict user behavior with smart UIs? In this talk, we will explore how we can make adaptive and intelligent user interfaces that learn from how individual users use your apps, and personalize the interface and features just for them, in real-time. With probability-driven statecharts, decision trees, reinforcement learning and more, UIs can be developed in such a way that it automatically adapts to the user's behavior.

Also a fervent open-source contributor, he is passionate about statecharts and software modeling, reactive animations, innovative user interfaces, and cutting-edge front-end technologies.

Memory: Don't Forget to Take Out the Garbage

Memory is fundamentally important to any computer program. It's a finite resource, and is limited on mobile devices more than it is on desktop. JavaScript does a remarkable job of hiding this complexity from us. What's going on behind the scenes, and how can you fix problems when memory runs out?

Reviving the Dream of the 90s with WebGL

If you’re like me, you’ve spent hours staring at Windows 98 screensavers when you were growing up. Sadly, screensavers are no more, but we’ve got the power to fix that. In this talk, I’ll walk you through how to harness modern technology to revive the dream of the 90s.

Using A-Frame, shaders, and other WebGL technologies, I’ll show you how to recreate some iconic imagery, including 3D Pipes, Mystify Your Mind, and The Maze.

Billy Roh

Billy Roh is a senior product designer at Opendoor. He helps organize a monthly meetup called WaffleJS in his spare time. Before Opendoor, he was a designer at Facebook, where he worked on profiles and advertiser tools.

It’s the best conference I’ve been to. It’s inspiring and you really understand the importance of JavaScript today.

Bring your learnings back to work

Online videos of all sessions, with integrated slides and audio will be made available to all attendees after the event. This ensures no one will miss a thing and your whole office can benefit. Watch all talks from previous years here.

Give a lightningtalk

We will have two lightning talk sessions scheduled, all conference attendees are welcome to contribute. Each talk should be around 5 minutes long - you can apply for a slot when you get to the conference, why not share some learnings from a project you’ve been working on or maybe take a firm stance on tabs vs spaces. Start preparing!

Share stories & learn from like minded

Nordic.js is created by developers for developers. Our ambition is to inspire and to get inspired, to meet and learn from others and to bring our community closer together.

Possibly the greatest JavaScript conference. The speakers, city, party and the small details in between.

Jakob Öhman, attendee 2015

Great food

We want you to have an all in all great experience and we believe that food is a big part of that. Therefore, we’re putting a big focus on food this year and will collaborate with a number of truly amazing restaurants.

The Party

The party or Festen as we like to call it (Swedish for party) is the official afterparty for Nordic.js. It’s also a celebration of our city and its amazing tech and startup community. Last year we had over 3000 people attending and we’ve had artists performing like Teenage Engineering, Lorentz, Beatrice Eli and Andreas Ferronato AKA Epic Sax Guy.

Dinner with strangers

As a way to make it easier for you to meet people you didn’t know from before we’re organizing something that we like to call Dinner with Strangers. It works like this: we reserve tables for six at our favorite restaurants around town and then we pair you up with five people you’ve never met before for a dinner. If you’re interested you can signup for one as the conference gets closer. It’s of course optional :)

Experience Stockholm

You’ll get to experience Sweden and Stockholm from it’s prettiest angle.

A good technical conference with a truly strong sense of community, sharing and learning.

Vitaly Friedman, smashing magazine

Let's partner up?

An event like this couldn’t happen without the support of sponsors and collaborators. Are you interested in being part of Nordic.js? Send us an email at We'd love to talk!

Diversity Tickets

What is it? 

Inspired by JSConf.EU, we’re excited to release a batch of Diversity Tickets. A Diversity Ticket is a fully sponsored (free) ticket given to someone from an underrepresented group in tech. This includes, but is not limited to: women, people of color, LGBTQ people, disabled people, and people facing economic or social hardships. 

How does it work? 

When purchasing a Diversity Ticket you’re making it possible for someone who for different reasons might not otherwise have been able to attend the conference and you’re thereby contributing to making tech and Nordic.js a more diverse place. Everyone who buys a Diversity Ticket will be publicly thanked and will be put up on the site as a Diversity Sponsor.

Who gets a ticket? 

You can apply for a Diversity Ticket here. Anyone from an underrepresented group in tech is invited to apply.
