For 2nd year in a row, we'll have Sébastien Morel, CTO at Crystallize, as our MC (master of ceremony). Expect lousy jokes and fun times.

09:30 AM CETHow AI Accelerate Front-end Development?
See details

In this talk, Teressa Wu will give a brief overview of a few keywords in AI and Machine learning, such as types of AI/ML, GPT, and prompts, which then lead into the conversation of how AI enables engineers to work better, giving a demo of making a front-end application using Bard. You will experience how AI can assist developers in creating code more efficiently. Then, it continues on to questions of whether there are any concerns or drawbacks and how front-end engineers should evolve to accelerate.

10:00 AM CETMonorepos & Spaceships
See details

Building a monorepo is like flying a spaceship: many people work together to ensure things don't go up in flames. In this talk, Max Kless will review tools, techniques, and best practices to help us put out fires and stay on course throughout our intergalactic journey.

Disclaimer: attending this talk probably doesn't qualify you to fly spaceships!

10:30 AM CETBreak & Networking
See details

The heart and soul of any conference is the networking part.

11:00 AM CETSimplify State Management and Testing with React Query
See details

Dive into React Query with David Ovrelid and uncover its power in simplifying data management. Explore its effortless data fetching, mutation handling, and seamless unit testing capabilities. Discover how React Query's built-in caching mechanism enhances performance and scalability, making it a game-changer for React developers.

11:30 AM CETFormidable Forms: Architecting Composable, Reusable, Testable & Modern Forms in React
See details

There are 1000 ways to get good form architecture wrong, and this talk is here to walk you through some sane decisions that guys at CERN are using in order to make the visitors of the new exhibition center & the back-office people happy. Cristian Schuszter will show you how to put together several different popular libraries to build the ultimate modular, testable, and composable forms (in a type-safe manner using Typescript). Forms are as old as the web, and the web was developed at CERN! So, who else other than us to give a talk about composable and modular forms?

12:00 PM CETLunch Break
See details

Grab something to eat (please try local Norwegian delicacies such as Brunost ("brown cheese") that was an absolute hit in the previous years) and network some more.

In this talk, Elian Van Cutsem will take a look at some of the newly released features in Astro 4 and how 2023 was such a crazy and amazing year for Astro. He'll dive deeper into some Astro concepts, like Islands architecture, view transitions, and how they changed the future of website development and can empower React users to deliver faster websites.

Of course, he'll do some live coding and have some fun. After that, let's take a look at what’s coming next for Astro.

14:00 PM CETSwiss Army Knife in Your Browser, i.e. Less Known Chrome DevTools Features
See details

Almost every web developer sooner or later encounters Chrome DevTools - a set of tools built into the browser that allow you to view the DOM structure, styling or requests sent by our application. However, do you know all the possibilities hidden in DevTools? In Dominika Zając's presentation, you'll see a few of these less known options - the most useful, amazing or simply interesting.

14:30 PM CETINP loves LoAF: Better Performance
See details

We’re going to look into Google’s new metric, which became part of Core Web Vitals in March 2024, and break down the INP. Additionally, Erwin Hofman will be diving into ways of tracking INP offenders: LoAF (Long Animation Frame), a Google Chrome API that allows site owners to track this in DevTools or RUM, allowing them to improve main thread work, responsiveness, and ultimately,, UX.

15:00 PM CETBreak & Networking

2019 Conference: The Beginning

React Day Norway was first arranged in 2019 at the beautiful seaside hotel Farris Bad. The conference was presented and organized by Crystallize as a community event. The day was packed with great talks from The New York Times, Slack, and Dropbox - to name a few. We wanted to keep the event small so everyone had the opportunity to talk and connect; speakers, sponsors, and attendees. The day ended with a BBQ at the terrace overlooking the sea and everyone enjoying the lovely Norwegian summer. The event was a huge success!

2021 Conference: Online

Sadly we had to cancel the 2020 event due to the pandemic and almost canceled 2021. The change of format came to the rescue. Again, a great lineup with speakers from Mailchimp, Tinder, Auth0, etc, and over 600 online attendees watching the live streams. BTW, you can still watch all the talks on our YouTube channel (or here on the website).

2022 Conference: In-person, Again.

Great talks, ReactShorts, amazing bike show, BBQ and after-party, and most engaging networking at the spectacular venue of Farris Bad Hotel in Larvik, Norway… that pretty much sums up 2022 React Norway.

2023 Conference: Setting a Standard

In 2022, you had come for React and stayed for Brunost. In 2023 we all savored the creamy delight of Brunost (thanks to our official Brunost sponsor TINE) as we sliced into new React realms! A standard has been set.

Spectacular Venue

Farris Bad enjoys an unbeatable location by the beach in Larvik, just 1.5 hours from Oslo Gardermoen Airport and 15 minutes from Oslo Torp Airport.
