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.

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.

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

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.

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 afterparty for Nordic.js. Previous years we’ve had over 3000+ people joining the event with artist performing like Teenage Engineering, Lorentz, Beatrice Eli and Andreas Ferronato. This year we’ve decided to make Festen a little bit different and a little bit more intimate. Putting a stronger focus on enabling conference attendees to connect and meet with other conference attendees in a playful and fun atmosphere.

With that said; the sauna wagon is booked, so is the bathtub, the barber & Phils Burgers. There will be VR, board games, Silent Disco, Code in the dark, plenty of interactive experiences and like always, free tattoos. We hope you’ll stay for it - it should be fun!

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? 

If you're not an underrepresented group in tech you can purchase a Diversity Ticket on the site and when you do you get two tickets, one for yourself and one 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. Diversity Tickets are priced at 10400 SEK and can be bought at

Who gets a ticket? 

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