Are you a React developer trying to get the most benefits from TypeScript? Then this is the workshop for you.
In this interactive workshop, we will start at the basics and examine the pros and cons of different ways you can declare React components using TypeScript. After that we will move to more advanced concepts where we will go beyond the strict setting of TypeScript. You will learn when to use types like any, unknown and never. We will explore the use of type predicates, guards and exhaustive checking. You will learn about the built-in mapped types as well as how to create your own new type map utilities. And we will start programming in the TypeScript type system using conditional types and type inferring.

Does your React app need to efficiently display lots (and lots) of data in a grid? Do your users want to be able to search, sort, filter, and edit data? AG Grid is the best JavaScript grid in the world and is packed with features, highly performant, and extensible. In this workshop, you’ll learn how to get started with AG Grid, how we can enable sorting and filtering of data in the grid, cell rendering, and more. You will walk away from this free 3-hour workshop equipped with the knowledge for implementing AG Grid into your React application.
We all know that rolling our own grid solution is not easy, and let's be honest, is not something that we should be working on. We are focused on building a product and driving forward innovation. In this workshop, you'll see just how easy it is to get started with AG Grid.
Prerequisites: 
Basic React and JavaScript
Workshop level:

Ensuring your code is ready for production without enabling your features to your entire user base used to involve a lot of guesswork. By using feature flags, we can allow our development teams to preview work-in-progress features and unreleased functionality in production without redeploying our code.
In this workshop, we’ll run through the fundamentals of feature flagging on both the client and server sides. We’ll cover working with LaunchDarkly’s SDKs within the context of a React application with a node backend, flagging at different places in the stack and give an introduction to rule targeting in the platform.

Anybody can write code that “works.” But what makes the best engineers stand out is their ability to create solutions that are clear, concise, testable and easy to understand and maintain. Join us as we explore two of React’s most powerful tools for well-architected solutions by starting with a suboptimal game codebase and refactoring it using industry best practices such as custom hooks, higher-order components (HOCs) and contexts.
- Introduction of the initial implementation and description of its issues.
- Presentation of the tools available to improve the code base.
- The mindset behind architecting clean solutions and refactoring.
- Highlevel passthrough of the code and creation of the plan.
- Extraction of code into utility functions.
- Extraction of state and effects into custom hooks.
- Grouping behavior into HOC.

With the rise of frameworks, such as React, Vue or Angular, the way websites are built changed over the years. Modern applications can be very dynamic and perform multiple API requests to populate a website with fresh content or submit new data to a server. However, this paradigm shift introduced new problems developers need to deal with. When an API request is pending, succeeds, or fails, a user should be presented with meaningful feedback. Other problems can comprise API data caching or syncing the client state with the server. All of these problems require solutions that need to be coded, but these can quickly get out of hand and result in a codebase that is hard to extend and maintain. In this workshop, we will cover how to handle API requests, API states and request cancellation by implementing an API Layer and combining it with React-Query.
Prerequisites:
To make the most out of this workshop, you should be familiar with React and Hooks, such as useState, useEffect, etc. If you would like to code along, make sure you have Git, a code editor, Node, and npm installed on your machine.

We know that React is for the web and React Native is for Android and iOS. But have you heard of react-native-web—for writing an app for Android, iOS, and the web in one codebase? Just like React Native abstracts away the details of iOS and Android, React Native Web extracts away the details of the browser as well. This opens up the possibility of even 
more
code sharing across platforms.
In this workshop you’ll walk through setting up the skeleton for a React Native Web app that works great and looks awesome. You can use the resulting codebase as a foundation to build whatever app you like on top of it, using the React paradigms and many JavaScript libraries you’re used to. You might be surprised how many types of app don’t really require a separate mobile and web codebase!
You will know:
- Setting up drawer and stack navigators with React Navigation, including responsiveness
- Configuring React Navigation with URLs
- Setting up React Native Paper including styling the React Navigation drawer and headers
- Setting up a custom color theme that supports dark mode
- Configuring favicons/app icons and metadata
- What to do when you can’t or don’t want to provide the same functionality on web and mobile
Prerequisites: 
- Familiarity with building applications with either React or React Native. You do not need to know both.
- Machine setup: Node LTS, Yarn, be able to successfully create and run a new Expo app following the instructions on
https://docs.expo.dev/get-started/create-a-new-app/

Are you satisfied with your test suites? If you said no, you’re not alone—most developers aren’t. And testing in React Native is harder than on most platforms. How can you write JavaScript tests when the JS and native code are so intertwined? And what in the world are you supposed to do about that persistent act() warning? Faced with these challenges, some teams are never able to make any progress testing their React Native app, and others end up with tests that don’t seem to help and only take extra time to maintain.
But it doesn’t have to be this way. React Native Testing Library (RNTL) is a great library for component testing, and with the right mental model you can use it to implement tests that are low-cost and high-value. In this three-hour workshop you’ll learn the tools, techniques, and principles you need to implement tests that will help you ship your React Native app with confidence. You’ll walk away with a clear vision for the goal of your component tests and with techniques that will help you address any obstacle that gets in the way of that goal.
you will know:
- The different kinds React Native tests, and where component tests fit in
- A mental model for thinking about the inputs and outputs of the components you test
- Options for selecting text, image, and native code elements to verify and interact with them
- The value of mocks and why they shouldn’t be avoided
- The challenges with asynchrony in RNTL tests and how to handle them
- Options for handling native functions and components in your JavaScript tests
Prerequisites:
- Familiarity with building applications with React Native
- Basic experience writing automated tests with Jest or another unit testing framework
- You do not need any experience with React Native Testing Library
- Machine setup: Node 16.x or 18.x, Yarn, be able to successfully create and run a new Expo app following the instructions on
https://docs.expo.dev/get-started/create-a-new-app/

In this workshop we'll cover the basics of GraphQL, and then use that knowledge to build a backend using SDL. Once we've created our schema, we'll run it locally, deploy to production, and create deployment branches for any changes to our schema. We'll finish the workshop by fetching data from our backend from the frontend, as well as adding authentication to lock down data access!
Mac setup with Node, and NPM (if you wish to follow along locally). Otherwise an account with CodeSandbox would do.

In this workshop, we'll take a tour through the most effective approaches to building out scalable UI components that enhance developer productivity and happiness :-) This will involve a mix of hands-on exercises and presentations, covering the more advanced aspects of the popular styled-components library, including theming and implementing styled-system utilities via style props for rapid UI development, and culminating in how you can build up your own scalable custom component library.
We will focus on both the ideal scenario---where you work on a greenfield project---along with tactics to incrementally adopt a design system and modern approaches to styling in an existing legacy codebase with some tech debt (often the case!). By the end of the workshop, you should feel that you have an understanding of the tradeoffs between different approaches and feel confident to start implementing the options available to move towards using a design system based component library in the codebase you work on.
Prerequisites:
- Familiarity with and experience working on large react codebases
- A good understanding of common approaches to styling in React
