React Beyond the DOM

In this workshop you’ll learn why we created FlashList at Shopify and how you can use it in your code today. We will show you how to take a list that is not performant in FlatList and make it performant using FlashList with minimum effort. We will use tools like Flipper, our own benchmarking code, and teach you how the FlashList API can cover more complex use cases and still keep a top-notch performance.You will know:- Quick presentation about what FlashList, why we built, etc.- Migrating from FlatList to FlashList- Teaching how to write a performant list- Utilizing the tools provided by FlashList library (mainly the useBenchmark hook)- Using the Flipper plugins (flame graph, our lists profiler, UI & JS FPS profiler, etc.)- Optimizing performance of FlashList by using more advanced props like `getType`- 5-6 sample tasks where we’ll uncover and fix issues together- Q&A with Shopify team

In this workshop, we discuss the merits of serverless architecture and how it can be applied to the AI space. We'll explore options around building serverless RAG applications for a more lambda-esque approach to AI. Next, we'll get hands on and build a sample CRUD app that allows you to store information and query it using an LLM with Workers AI, Vectorize, D1, and Cloudflare Workers.

Leveraging reactjs to create reusable microfrontends addressing challenges and common pitfalls.

Compared to unit testing, end-to-end testing aims to interact with your application just like a real user. And as we all know it can be pretty challenging. Especially when we talk about Mobile applications.
Tests rely on many conditions and are considered to be slow and flaky. On the other hand - end-to-end tests can give the greatest confidence that your app is working. And if done right - can become an amazing tool for boosting developer velocity.
Detox is a gray-box end-to-end testing framework for mobile apps. Developed by Wix to solve the problem of slowness and flakiness and used by React Native itself as its E2E testing tool.
Join me on this workshop to learn how to make your mobile end-to-end tests with Detox rock.
Prerequisites- iOS/Android: MacOS Catalina or newer- Android only: Linux- Install before the workshop

- Intro - Cleo & our mission- What we want to build, how it fits into our product & purpose, run through designs- Getting started with environment set up & “hello world”- Intro to React Native Animation- Step 1: Spinning the wheel on a button press- Step 2: Dragging the wheel to give it velocity- Step 3: Adding friction to the wheel to slow it down- Step 4 (stretch): Adding haptics for an immersive feel

Deploying React Native apps manually on a local machine can be complex. The differences between Android and iOS require developers to use specific tools and processes for each platform, including hardware requirements for iOS. Manual deployments also make it difficult to manage signing credentials, environment configurations, track releases, and to collaborate as a team.
Appflow is the cloud mobile DevOps platform built by Ionic. Using a service like Appflow to build React Native apps not only provides access to powerful computing resources, it can simplify the deployment process by providing a centralized environment for managing and distributing your app to multiple platforms. This can save time and resources, enable collaboration, as well as improve the overall reliability and scalability of an app.
In this workshop, you’ll deploy a React Native application for delivery to Android and iOS test devices using Appflow. You’ll also learn the steps for publishing to Google Play and Apple App Stores. No previous experience with deploying native applications is required, and you’ll come away with a deeper understanding of the mobile deployment process and best practices for how to use a cloud mobile DevOps platform to ship quickly at scale.
