    The only thing I get as excited as I get for JavaScript is ramen. Each of my projects lately is built around Next.js in which I found my ultimate productivity hack. I am an aspiring tech-educator, although I spend more time tinkering with my blog than actually writing on it. As of late, I focus on helping Saleor Commerce customers to be at their most productive with the platform, and on gaining consistency with my YouTube channel. The time I have left goes to reading, cooking (did I mention ramen?) and sports.

  • Back in the game: Recent Revolutionary Changes in Angular

    Tomasz Ducin

    Tomasz Ducin avarat

    Angular has been perceived as a rather complex framework by some, yet it's used massively by enterprise-scale systems. Whether we agree with the criticism or not, the framework is undergoing a monumental transformation. In recent months, Angular is experiencing a period of frequent and significant updates and - at least considering previous years of stagnation - groundbreaking changes. These include not only the features, public API and architecture, but also to the mental models that developers come up with.

    Let's review the best concepts introduced to most recent versions of Angular and analyze the architectural and DX benefits they bring, as well as their downsides. We'll also compare the most recent solutions to competing frameworks.

  • Next.js is my main web server for all APIs. And I like it!

    Michał Michalczuk

    Michał Michalczuk avarat

    Why you won’t use anything more specialised like Fastify or Nest? Why you are using Next.js not in the way it was designed? You might ask.

    Because it is way good enough for my cases, and more flexible than I initially thought.

    In this presentation, I’ll give you arguments for betting on Next.js as a delivery layer for your REST & GraphQL APIs.

    With a sip of middleware, some libraries, and tweaking the next.config you can squeeze a lot from it. But .. is it performant? Well, we will see :)

  • Coffee Break 1

  • Astro: Built Fast by Default

    Ruby Jane Cabagnot

    Ruby Jane Cabagnot avarat

    Astro version 4.0 just launched, allowing developers to build server-rendered websites with any JavaScript framework. It uses the Islands architecture and partial hydration to deliver fast apps with frameworks like React, Vue, Svelte, and more. Could this be the ultimate web framework? Let's find out.

    Focus on Astro's commitment to performance. We'll examine how its architecture inherently leads to faster websites, impacting user engagement and conversions, and how it achieves this through less reliance on client-side JavaScript.

  • It Takes a Nation of Millions to Hold Us Back

    Theodore Vorillas

    Theodore Vorillas avarat

    Next.js is a popular tool for building rich web applications. In this presentation, I will show you how to scale your Next.js application from a small number of users to millions without breaking the bank or getting tied to a specific hosting platform.

    Using industry standards like Docker, CI/CD pipelines and git we'll walk together through the art of building scalable applications that can seamlessly adapt to your business's growth trajectory.

  • Background jobs 101: building reliable apps with Inngest

    Sylwia Vargas

    Sylwia Vargas avarat

    This talk offers a gentle introduction to a new paradigm of durable workflows by walking the audience through a common use case: user onboarding email campaign.

    I’ll show how the DIY approaches tend to be slow and unreliable — or require significant investment of resources. Instead, by embracing background jobs you can deliver a great User Experience and stress-free ops.

    Given how more and more companies favor short development cycles and lean approach to headcount, being able to own entire business workflows end-to-end turns (formerly) front-end teams into empowered product teams.

  • Rethinking frontend architectures with data layers

    Max Stoiber

    Max Stoiber avarat

    After speaking with thousands of engineers at hundreds of companies, we noticed a peculiar pattern in how the fastest-moving companies manage the interface between backend and frontend: they all have a data layer. Let's dive into what data layers are, why these companies can move faster by having them, and how you can build your own with Fuse.js, a framework tailor-made for frontend teams to build data layers.

  • URL: your state management solution for Next.js 14

    Adrian Pilarczyk

    Adrian Pilarczyk avarat

    Since Next.js 14 released, many people are wondering how the latest changes affect its state management landscape. Since there is quite a lot of ground to cover, I would like to focus on only one piece of it that gets mentioned more frequently than ever: the URL.

    In many recents comments, it seems like the Next.js team wanted to remind us of a state management solution that is global, reliable, and providing unique benefits. In my talk, I want to show how far you can go with managing state in the URL, when it makes sense to use it and when you really shouldn't.

    Expect to cover all the Next.js hooks that make up the URL state management toolkit, how we can create our own URL abstraction of React's `useState` hook, how to use nested routes to express the state of UI in the URL, and many more. All of that, on a practical example of an e-commerce shop.

  • WordPress Wars. Is React a New Winner?

    Lena Sędkiewicz

    Lena Sędkiewicz avarat

    Everybody knows WordPress. Some love it, some hate it. But in recent years it evolved in a direction where being a WordPress dev can mean different things. On one side we have people who base on plugins, configuration skills and some HTML and CSS added. On the other hand, more and more code that can be implemented is based on React. More and more developers hear excited cries from SEO specialists who demand introducing headless WordPress - which means use of Gatsby or Next JS - for CWV improvement purposes.

    In the times of WordPress Wars, when simplicity mixes with complexity, will React be the new winner?

  • Empowering OpenTelemetry: How we made Next.js app work with a self-hosted collector

    Przemysław Łada

    Przemysław Łada avarat

    Embark on our journey to unlock the full potential of OpenTelemetry. Collect traces, logs, and metrics and go beyond Vercel-supported integrations. I will share tips and tricks on achieving this by sending telemetry signals to self-hosted collectors, unlocking new possibilities for observability.

    Note: This approach is tailored for serverless functions and is not applicable to edge or client-side code.

  • Keep your friends close and your APIs closer

    Jakub Wąsik

    Jakub Wąsik avarat

    I’ll introduce you to the Backend For Frontend pattern. You will see how we are using it in the organisation for our microfrontends architecture and how Next.js grants you that capabilities out of the box for your projects. Finally we will discuss the benefits and drawbacks of befriending APIs with your clients via BFF.

  • Fullstack can be fun (again)

    Fran Zekan

    Fran Zekan avarat

    Around five years ago, full-stack complexity peaked. Ever since, it has been slowly coming down. And with the advent of RSC in Next13, it halved. In this talk, you'll see a example of how the new patterns make it way easier to fetch and mutate data compared to all previous paradigms. We’ll also quickly compare it to graphql-ear code and some PHP code we all wrote 10 years ago.

  • All Things Astro

    Elian Van Cutsem

    Elian Van Cutsem avarat

    Astro 4 has just been released and brought some amazing new features with it.

    In this talk, we’ll take a look at some of the newly released features in Astro 4, how 2023 was such a crazy and amazing year for Astro.

    We'll dive deeper in some Astro concepts, like Islands architecture, view transitions, and how they changed the future of website development.

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

    We'll be covering what Astro is, so everyone understands its concepts. We'll dive a bit deeper into the releases we did this past year (2023). Astro 2, Astro 3 and Astro 4's main features. Also showcasing some Starlight, and maybe even a bit of Astro Studio 👀

  • Interactive web apps at the Edge with Remix, Neon, and Prisma

    Alberto Schiabel

    Moreover, you will see how to query a Neon database using the familiar and type-safe Prisma ORM.

    Finally, you will gain practical insights about the nuances and caveats of Edge platforms, as Alberto shares firsthand experiences from making the Prisma internals compatible with this innovative computing stack. Are you ready for the future?
