One-track conference, full-stack festival.

Get ready to shred your React and frontend limits at React Norway 2026. On June 5th, we’re turning Rockefeller — the legendary heart of Oslo's music scene — into an epicenter of React revelations. This isn’t your usual developer conference. It's loud, it's live, and it's unapologetically authentic.

Secure your spot in the pit; let’s React and rock🤘

React with Caution: How to Hack Your React App (And Fix It Too)

Ramona Schwering

React has your back, at least on paper. With almost no CVEs in recent years, React Core stands out as one of the most secure frontend frameworks available. But security isn’t automatic.

In this practical, hands-on session, Ramona will actively hack a React application to expose real-world threats like XSS, injection attacks, and subtle frontend vulnerabilities. You’ll learn where React protects you by default, where it doesn’t, and how to become the final line of defense for your users.

10:00 AM CET

Rockin' With TanStack Start and AI!

Jack Herrington

Let your application fly with an all-new TanStack Start, an all-new client-first full-stack framework in combination with TanStack AI, the cutting-edge AI integration platform that makes it simple to bring AI into your applications, not just with chat but with full multimedia capabilities, image and video generation, and more!

Coffee Break and Networking

Costa Alexoglou
11:00 AM CET

So, You Want to Build a Pair-programming App with JavaScript, Good luck

Costa Alexoglou

In this talk, together with Costa, you will explore lessons learned from maintaining one of the few open-source remote pair-programming apps designed for super-low latency.

Lessons like local caching in desktop apps and how it works, syncing state across different windows, measuring video latency hacks, and things he and his team wish they had known before they started, like how much they hate WebKit.

11:30 AM CET

No Researchers Were Harmed in the Making of This Test Suite

Dora Makszy

What if UX research could move as fast as your sprint cycles? In this talk, you’ll see how an automated, self-service testing framework built with Figma Make captured real user behavior at scale, delivering quantitative insights in days, not weeks. It’s a practical blueprint for embedding fast, “good enough” UX validation directly into modern product teams without slowing development down.

12:00 PM CET

Dead Code Shouldn’t Exist: How We Removed 28k Lines of Code, One Knip at a Time

Dominik Dorfmeister

How much of your codebase is just sitting there unused? In this session, you’ll see how Sentry used Knip to uncover and safely remove dead files, exports, and dependencies; and what they learned from the messy edge cases along the way. Expect practical tactics you can apply immediately to declutter your frontend and keep it lean.

12:30 PM CET

Lunch

13:30 PM CET

Architecting Observability in Modern React Apps

Neha Sharma

Frontend observability goes far beyond console logs and error boundaries. In this talk, you’ll learn how traces, metrics, logs, and correlation IDs fit into a modern enterprise observability strategy, and how to design React systems that are measurable and resilient from day one. Expect concrete patterns for integrating observability into CI/CD and building a culture of visibility across teams.

14:00 PM CET

Designing the In-Between States with Async React

Aurora Scharff

Some of the most important UX moments happen between click and render. In this session, you’ll explore how Async React and Next.js 16 help you architect loading states, errors, and transitions with intention; not as afterthoughts. Expect practical patterns for skeletons, error boundaries, and design-owned loading components that make your app feel faster, smoother, and more polished.

Nico Martin
14:30 PM CET

Look ma, No Hands! Multimodal AI-Agents in the Browser

Nico Martin

In this talk, together with Nico, we’ll explore how to build multimodal AI agents that understand voice, interpret images, hold short-term memory, and respond intelligently - all running entirely in the browser. No server, no cloud APIs, and no installation. Using modern tools like WebGPU and WebAssembly, we’ll see how far the open web has come in enabling real-time, privacy-preserving AI experiences.

15:00 PM CET

Coffee Break and Networking

iIsograph — a Compiler for Your UI

Robert Balicki

Tired of boilerplate and guessing whether your data fetching is actually correct? This talk introduces Isograph, a compiler-driven framework that scans your codebase and generates exactly the queries and runtime artifacts your UI needs; no more, no less. With simple annotations for dynamic loading, pagination, and component-level code splitting, you’ll see how a compiler can eliminate whole classes of mistakes while making data-driven React apps more stable and performant by default.

Rockefeller

Rockefeller will host our next React Norway — a legendary downtown Oslo concert hall inside the historic Torggata Bad, first opened in 1986. The venue fits about 1,300 people.

Known for its year-round shows featuring Norwegian and international headliners — and festivals like Inferno — Rockefeller brings professional-grade production and electric city-center energy to our new format.

Comfort Hotel Xpress Youngstorget is located just a few steps away from the Rockefeller and a 10 min. walk from the train station (Oslo S). We are happy to announce that attendees receive a 15% discount for bookings in the period 03.06.2026-06.06.2026. You will receive details for booking in the confirmation e-mail when you buy your Rock & React ticket. Please note that this offer is subject to availability.

2019 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 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 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 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.

2024 React the Viking Way!

With all the talks, brunost, bikes flying around, and fantastic food, it was challenging to top last year’s event. It was a challenge worth of Viking sagas. Thankfully, we like challenges, and we threw more brunost in the loop🤘

2025 Reboot your dev game!

Bigger venue, same core: React, Reload, Repeat. Old-school, pixel art style for a bigger venue of Scandic Holmenkollen Park Hotel in Oslo. 350 people enjoyed 13 well-known speakers and a few n00bs in engaging talks.
