Thinking & Coding Algorithms (In-Person)

If you don't already have a solid computer science background, most of the typical algorithms used in industry-wide job interviews can be intimidating. Moreover, even experienced engineers sometimes struggle to apply proper algorithmic thinking in their production code. This workshop starts at a basic problem/solution, and layers up to complex algorithms for a variety of challenging tasks. Whether attendees have computer science education or not, they will leave this workshop with practical algorithms knowledge, prepared to tackle problems by first thinking algorithmically and then translating that into efficient code.

Table of contents
  • - Learn how “Big O” classification impacts both computation time and memory usage (and the tradeoffs)
  • - Explore how data structures (classic and custom) shaped to the nature of the problem lay the groundwork for better algorithms
  • - Learn basic techniques for benchmarking computation time and memory usage

18+ months of experience in JS. Attendees code along with presenter, so must have a comfortable basic dev environment (editor, browser, git).

Workshop level
Mid-to-senior level software developers (JS).

TypeScript Deep Dive (In-Person)

In this workshop, we'll start with the basics of TypeScript for beginners, and then progress through advanced patterns such as discriminated unions, generics, and advanced inference.

To finish, we will port an existing JavaScript codebase (https://github.com/tupuio/tupuapp) to TypeScript and learn along the way.

Advanced React (In-Person)

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 (see table of content).

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.

Table of contents
  • - introduction to <Suspense> and <SuspenseList>
  • - new concurrent rendering APIs: startTransition, useDeferredValue
  • - new Hooks: useId, useSyncExternalStore, useInsertionEffect
  • - strict effects in the new Strict Mode
  • - automatic batching and flushSync
  • - sneak peek into what's coming after React 18

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.

Please have Node 16+ and Yarn installed on your machine.

Senior Mindset Workshop: Think like a *True* Senior Engineer (In-Person)

Getting that senior title is easy. Just stick around. Being a true senior takes a new way of thinking.

You're a great engineer. You can code anything you need, solve every problem, google any solution. Your code is flying.

But somehow you're ... stuck. Interviewing feels rough, you pass the coding and fail the real stuff. Culture and system. At work they keep giving you stupid little problems with no growth. You crave challenge and keep tweaking CSS instead. You want some responsibility, damn it! What's that coworker got that you don't? Most of all you crave autonomy. The freedom to tackle big challenges and help the company with your brilliance. They don't even see all the bad code you see! How can they live like this?? Instead of autonomy, you're getting babysat. Managers asking what you're up to, daily standups that feel like a drag, pushback and 'maybe someday' on every idea that you give. I was like that a few years ago. A totally senior engineer who keeps running into walls and getting stuck. Now even bigger companies trust me with designing systems and leading teams on projects that could make or break the company. In this workshop you'll learn what changed and how to apply the Senior Mindset to your work and career:

  • How to gain autonomy
  • Inspire trust
  • Own large projects
  • Get freedom to experiment
  • Have your ideas heard
  • Think like an expert
  • Become a decision-making peer, not a pair of hands

You'll work on case studies, analyze anecdotes, discuss insightful books, and look at your work and career in a new light.

Advanced Remix Workshop (Remote)

Now that you're on your feet with the basics of Remix, we can do some really exciting things. The cool thing about Remix is that you can start and ship the simple implementation and then incrementally add more complexity to it over time without completely rearchitecting your solution or changing your mental model. And that's what we'll be doing in this workshop. All while keep your app fast and bug-free–just the way your users like it.

At the end of this workshop, you'll know how to:

Eliminate busy indicators with Optimistic UI (while still handling errors)

Optimize Remix's automatic data revalidation after mutations

Fetch data outside of navigations for data driven components like Combobox/Autocomplete

Build global, animated navigation indicators, aware of submissions, revalidation, and redirects

Step up your app's accessibility with focus management

Make imperative data mutations (for things like mutations on keyboard shortcuts)

and more!

Workshop schedule & location

June 23-24, 17:00-21:00 CEST. Remote via Zoom.

Advanced React Patterns (Remote)

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.
