React Performance (April 14)

React is fast, until it isn't

In this workshop, you'll learn everything you need to diagnose, profile, and fix performance problems in your React application using the Browser Performance Profiler, React DevTools Profiler, and proven React optimization techniques.

The tools we have for profiling React Applications are extremely powerful, but they can often be really difficult to grok. Sure, starting a profiling session is simple enough, but how do you go from all the information in the flamegraph to actionable steps to improve your application's performance? And once you know what parts of your app are causing performance issues, what then? How do you optimize your React components without making the whole application a complex mess?

Oh, and don't forget that you should profile your app in production mode to make sure you get accurate measurements. Do you know how to do that?

Hi, I'm Kent C. Dodds and in my latest workshop I'll teach you the ins and outs of optimizing React applications. I will take you on a deep dive browser profiling tools, and show you what you need to know to start using them to make your applications fast right away.

React Advanced (April 14)

Full-day, hands-on coding workshop to explore advanced patterns and new features in React. React may be just a simple UI library, but it involves a pretty big ecosystem around it. Explaining the basics and internals is not enough, so in this module we're going to explain the best practices, we're going to learn to "think in React", and apply solutions to real problems that you might encounter in the process of building an app.

We'll explore all the advanced techniques for making flexible and maintainable React components. We'll see how using popular patterns like Higher Order Components, Compound Components, Render Props etc. can help us in simplifying things, making our components more reusable and our apps more declarative.

React 16 comes with some major changes and an update to the core algorithm. In this module, we'll explore some practical use-cases for Hooks, Portals, Fragments, Error Boundaries etc. We'll see how the new Context API can simplify state-management and we'll play with a new feature called react-call-return.

Modern React (April 15)

One of the most popular workshops from React Amsterdam 2019.

After some years of silence, React team had recently landed a number of new additions to it's library enabling application developers to optimize their code both for better performance and maintainability. Max will guide your through emerging patterns and show you by example how you can start applying the new best practices in your production apps.

GraphQL Workshop (April 15)

This one-day workshop will teach you everything you need to know to incorporate GraphQL into your application. During the first half of the workshop, we'll explain the basics of a GraphQL and we’re gonna build a GraphQL server, covering best practices for architecting your schema, error handling, authentication, and permission layers. In the second half of the workshop, we’ll connect our GraphQL server to a React application with Apollo Client. We’ll break down the modular architecture of the client and teach you how to set everything up and use queries and mutations. We’ll show a few different approaches for working with Apollo: Higher Order Components, Render Props, and hooks. Throughout the course of the workshop, you’ll learn practical tips for using GraphQL in production.

Building WhatsApp in a Day with React Native (April 15)

In this full day workshop we will go through the process of creating Whatsapp app in React Native from scratch. We will talk about how to get started, structure our app and create proper navigation workflow, style our screens and create compelling animations. But we will not stop there. Not only React Native is changing mobile ecosystem nowadays, GraphQL is also an important part of how we connect to our backend.

We will go through GraphQL basics and use it in our Whatsapp app to connect to GraphQL endpoint which we will also define and create during workshop by using free and open source Hasura GraphQL engine. Workshop will give you the ultimate experience of creating React Native app from scratch with GraphQL API.

Testing React Applications (April 15)

Use jest, jest-dom, and React Testing Library to write unit and integration tests for React Components Writing React applications is pretty easy, but shipping those applications with confidence is an entirely different story. How do you know that your changes work? How do you know those changes aren’t going to break other parts of your application? Do you have to manually walk through your whole application to make certain everything’s still working? No thank you! The more your tests resemble the way your software is used, the more confidence they can give you. Let’s learn how to write tests that make us confident.

In this hands-on workshop we’ll work on adding tests to existing components as well as use our tests to speed up our workflow building new components. We’ll work with everything from simple components and JavaScript functions to complex components with asynchronous logic.

Building your first Design System: from scratch to production (April 15)

This is a hands-on workshop for React developers in which you will learn how to define a common language for collaboration and iterate on products faster.

Learn the best practices of component driven design and how to standardize your design patterns. Leverage React to build design tokens and a component library that can be used in products and can evolve as teams use it. At the end of the day, you will have a small but complete Design system implementation that will cover the full product lifecycle.

Advanced Next.js with Core Members (April 16)

Throughout this workshop, we will dive deep into Next.js and all of the features it offers to enhance your development experience and to create optimized production applications. We will also be discussing newly added features/APIs which can be leveraged to streamline development even further!

React Native Animations (April 16)

Everything in the world is animated and animating our apps is a key to make them look compelling, "telling a story" of your app as well as reducing cognitive load for your users. Animations can be as simple as bouncing buttons or complex like full screen transitions, gesture based animations and multi layered animations. Not only animations sometimes are not that straightforward to implement, they have to look "realistic" as well as to be performant.

In this workshop we will get from the very basics of creating compelling animations in React Native to complex gesture animations, custom transitions, purely native animations and so on. We will discuss performance bottlenecks and work around them to get 60FPS animations. This workshop is targeted towards developers already familiar with the basics of React Native and want to level up their knowledge understanding all the intricacies of animating in React Native.

CSS-in-JS - from “why” to “how” (April 16)

CSS-in-JS is a largely misunderstood approach to styling web applications due to the history of the web and a variety of use cases. After it’s early adoption in 2014, the community is widely using it for real-world high scale projects today and is still exploring the impact and improving the tech.

We are going to learn foundational ideas behind it by building our own CSS-in-JS library. We will explore the downsides and benefits of certain design decisions we will make on the way. Then we will dive into some advanced concepts and implementation details using popular libraries like Styled Components and JSS.

Advanced React Workshop (April 16)

React keeps innovating and bringing new and better features. Despite this constant change, the principles of React remain the same: composition, immutability, purity... in other words, functional programming principles. In this advanced workshop, you will learn how to implement advanced features in React applying functional programming in JavaScript without using any other libraries.

TypeScript for React Devs (April 16)

The JavaScript Eco System is moving to TypeScript. Fast. TypeScript has some unique, very powerful features that fit very well with the dynamic nature of the JavaScript language. This workshop will get you up and running with all the basics and the most important advanced patterns of TypeScript.

But beyond that, this is a workshop for React devs! So we will discuss extensively how to combine TypeScript with a React code base. To practice the theory, during the hands-on parts of this workshop we will be migrating an application from plain JavaScript to TypeScript.
