  • Data Visualization for React Developers

    Data Visualization, aka "dataviz", is much more than drawing some pretty charts; it's a process of discovering & communicating insights derived from data. In this workshop, through hands-on projects using the visualization libraries Observable Plot and D3.js, we’ll explore the basic concepts & techniques dataviz professionals use to find meaning in the data that matters most to you & your users, and how to convey that meaning effectively using custom interactive visualizations in your React apps.

    Table of contents

    • Exploratory vs. Explanatory dataviz, and when to use each
    • Data features, encoding channels, and mapping between them
    • Aggregation & faceting techniques to expose meaningful patterns
    • How to use Observable Plot’s high-level grammar of graphics for rapid exploration & simple visualizations
    • How to get started with the powerful, low-level D3.js library to create highly customized visualizations
    • How to wire our Plot & D3 charts into our React apps


    Everyone is welcome, but this workshop is aimed at intermediate and advanced React developers who are beginners in the field of Data Visualization. We will assume basic familiarity with React Hooks (e.g. useState, useEffect), DOM and SVG fundamentals.

    Participants should bring a laptop with their browser & code editor of choice, Git and Node installed.

  • TypeScript, Deep Dive

    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

  • Advanced React

    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

    The workshop is split into several modules. Each of them starts with a 20 min presentation, 30-50 min coding session and is followed by a 10 min retrospective. The final topic about what's coming after React 18 is only covered as a presentation.

    By the end of the workshop you will be able to leverage the new features of React 18 and be able to use them in production ready applications.


    This workshop is targeted for intermediate and experienced React developers. You should be comfortable using Hooks (incl. useEffect, useRef) and basic understanding of Concurrent Mode is recommended but not required.

    October 19, 2022, in-person in London. Location - Avonmouth House, 6 Avonmouth St, London SE1 6NX, United Kingdom.
