Advanced React Patterns (in-person)

Date & time: May 30, 9:00-18:00 CEST. In-person in Amsterdam, the venue – Aristo meeting center (Teleportboulevard 100, 1043 EJ Amsterdam).

Come to the workshop with some basic knowledge in React (with hooks) and we'll teach you some of the most reliable and resilient patterns for creating advanced React code that can be re-used in your applications. This workshop will be ideal for those creating "library code". In other words, highly composable and reusable code to be shared across an organization or a large project.

TypeScript, Deep Dive (in-person)

Date & time: May 30 (Group 1) & 31 (Group 2), 9:00-18:00 CEST. In-person in Amsterdam, the venue – Aristo meeting center (Teleportboulevard 100, 1043 EJ Amsterdam).

More and more projects are using TypeScript. This workshop will provide a deep dive into the language, and basic TypeScript knowledge is assumed. We will briefly discuss the design philosophy of TypeScript, and then cover all the lesser-known or harder features. That is: do all the cool and weird meta programming stuff (TS is turing complete!) and learn the tricks you won't find in the handbook.

So join if you feel like you're writing too much type annotations to make TypeScript happy! We'll dive deep into how type inference and control flows works, and how you can make the compiler work for you. We'll discuss all the fancier language constructs like:

  • ReturnType<>, Parameters<>
  • typeof, keyof
  • Mapped types
  • ConditionalTypes
  • Function overloading
  • Discrimination unions
  • Type guards and type assertions
  • String template types
  • (Variadic) tuple types

Everything New in React 18 and Beyond (in-person)

Date & time: May 31, 9:00-18:00 CEST. In-person in Amsterdam, the venue – Aristo meeting center (Teleportboulevard 100, 1043 EJ Amsterdam).

React 18 was a long-awaited release. New APIs were introduced and certain behaviour changed. Some of these changes have quite an impact on your daily development, while others rarely affect you. Nevertheless, only by knowing your tools can you best decide when to use which of them.

In order to get a deep understanding of these new APIs and behaviour changes we will explore the following topics:

  • new concurrent rendering APIs: useTransition, startTransition, useDeferredValue
  • new Hooks: useId, useSyncExternalStore, useInsertionEffect
  • strict effects in the new Strict Mode and revisiting useEffect
  • automatic batching and flushSync
  • sneak peek into what's coming after React 18 including a brief introduction into and for data fetching

Building WebApps That Light Up the Internet with QwikCity

Date & time: June 12, 16:00-19:00 CEST. Remote via Zoom.

Building instant-on web applications at scale have been elusive. Real-world sites need tracking, analytics, and complex user interfaces and interactions. We always start with the best intentions but end up with a less-than-ideal site.

QwikCity is a new meta-framework that allows you to build large-scale applications with constant startup-up performance. We will look at how to build a QwikCity application and what makes it unique. The workshop will show you how to set up a QwikCitp project. How routing works with layout. The demo application will fetch data and present it to the user in an editable form. And finally, how one can use authentication. All of the basic parts for any large-scale applications.

Along the way, we will also look at what makes Qwik unique, and how resumability enables constant startup performance no matter the application complexity.

Build a Universal Reactive Data Library with Starbeam

Date & time: June 14, 18:00-19:30 CEST. Remote via Zoom.

This session will focus on Starbeam's universal building blocks. We'll use Starbeam to build a data library that works in multiple frameworks.

We'll write a library that caches and updates data, and supports relationships, sorting and filtering.

Rather than fetching data directly, it will work with asynchronously fetched data, including data fetched after initial render. Data fetched and updated through web sockets will also work well.

All of these features will be reactive, of course.

Imagine you filter your data by its title, and then you update the title of a record to match the filter: any output relying on the filtered data will update to reflect the updated filter.

In 90 minutes, you'll build an awesome reactive data library and learn a powerful new tool for building reactive systems. The best part: the library works in any framework, even though you don't think about (or depend on) any framework when you built it.

Build and Deploy a Backend With Fastify & Platformatic

Date & time: June 7, 16:00-19:00 CEST. Remote via Zoom.

Platformatic allows you to rapidly develop GraphQL and REST APIs with minimal effort. The best part is that it also allows you to unleash the full potential of Node.js and Fastify whenever you need to. You can fully customise a Platformatic application by writing your own additional features and plugins. In the workshop, we’ll cover both our Open Source modules and our Cloud offering:

  • Platformatic OSS (open-source software) — Tools and libraries for rapidly building robust applications with Node.js (oss.platformatic.dev).
  • Platformatic Cloud (currently in beta) — Our hosting platform that includes features such as preview apps, built-in metrics and integration with your Git flow (platformatic.dev).

In this workshop you'll learn how to develop APIs with Fastify and deploy them to the Platformatic Cloud.

(We’ll be shipping lots more features at JSNation, stay tuned for updates!)

0 To Auth In An Hour For Your JavaScript App

Date & time: May 17, 16:00-17:00 CEST. Remote via Zoom.

Passwordless authentication may seem complex, but it is simple to add it to any app using the right tool.

We will enhance a full-stack JS application (Node.js backend + Vanilla JS frontend) to authenticate users with One Time Passwords (email) and OAuth, including:

  • User authentication - Managing user interactions, returning session / refresh JWTs
  • Session management and validation - Storing the session securely for subsequent client requests, validating / refreshing sessions

At the end of the workshop, we will also touch on another approach to code authentication using frontend Descope Flows (drag-and-drop workflows), while keeping only session validation in the backend. With this, we will also show how easy it is to enable biometrics and other passwordless authentication methods.

Solve 100% Of Your Errors: How to Root Cause Issues Faster With Session Replay

Date & time: May 30, 18:00-19:00 CEST. Remote via Zoom.

You know that annoying bug? The one that doesn’t show up locally? And no matter how many times you try to recreate the environment you can’t reproduce it? You’ve gone through the breadcrumbs, read through the stack trace, and are now playing detective to piece together support tickets to make sure it’s real.

Join Sentry developer Ryan Albrecht in this talk to learn how developers can use Session Replay - a tool that provides video-like reproductions of user interactions - to identify, reproduce, and resolve errors and performance issues faster (without rolling your head on your keyboard).

JS Open Source Awards

The main goal of this project is to shed some light on great open source projects that don’t receive enough attention on a regular basis.

We’re looking at OSS projects or initiatives following an open and transparent culture, especially those eager to collaborate and receive contributions from anyone interested.

GitHub stars are not our criteria, and we’re looking for hidden gems that may not have enough marketing power or huge companies behind them.
