What we learned rebuilding the largest Nordic electronic retail website in Next.js 14?

Web performance is very important for many websites, and it is crucial if you are the largest electronic retailer in the Nordics. As many of you already know, the performance of the Elkøp/Elgiganten/Gigantti site has not been good enough, and that is something Tomas set out to fix. Although the website was fairly new, it failed to meet expectations, leading to a decision to rewrite the frontend using Next.js and host it on Vercel.

By the time of NDC Oslo, we should be able to see the results of the rewrite, and Tomas will share some of the learnings made along the way. Why was Next.js picked? How does the new app router work in a larger project? What is it like to work with Vercel? How do you pitch ideas like this in larger organizations?

Learnings from One Year in Production with Next.js on Vercel

We've been live with our Next.js solution for over a year now, and it's time to share what we've learned. What are the key things you need to consider when building a high-performance site with Next.js and hosting it on Vercel?

In this session, we'll talk about the important decisions we made to create a fast and efficient website for the largest electronics retailer in the Nordics. We'll also cover topics like feature toggling, A/B testing, how to serve different versions of the site to various customers without sacrificing performance and more.

By the end of this session, you should have a better understanding of the key concepts for building a high-performance website using Next.js on Vercel, and how to set it up to move quickly with your implementation.

First time for this talk. It is follw-up on my talk from last year but where I will go into some more details on some specific concepts.
