The day I broke React Native

4th November 2022 - It was just a regular day for the “release crew” as we were approaching to prepare the first release candidate for React Native 0.71. Little did we know how an innocuous release could have triggered a domino effect resulting in failing builds for nearly every React Native developer out there. With the wisdom of hindsight, we’ll walk through what happened, what are our lessons learned and the lowlights of this incident. We’ll have the opportunity to look through the internals of React Native, discover our incident-response culture, and learn how we’re hardening our ecosystem to protect us against similar events in the future. Join me as we revive this incident, and don’t miss this opportunity to gain insights, be inspired, and embrace the lessons learned from the day I broke React Native.

Speaker BIO:

Nicola Corti is a Google Developer Expert for Kotlin. He has been working with the language since before version 1.0, and he is the maintainer of several open-source libraries and tools for mobile developers.He's currently working in the React Native Core team at Meta, building one of the most popular cross-platform mobile framework.Furthermore, he is an active member of the developer community.His involvement goes from speaking at international conferences to being a member of CFP committees and supporting developer communities across Europe.In his free time, he also loves baking, podcasting, and running.

Build Your Mental Model of React’s Rendering Behavior

Join me as we explore the intricacies of React's rendering system and develop a comprehensive mental model of how it works. We'll build data-driven schemas to examine how React tracks its elements and their data over time and determines which components need to be updated. But be prepared: we’ll need to talk about fibers. By delving deeper into React's inner work, we'll be better equipped to identify performance issues and troubleshoot tricky bugs in our daily life.

Static Hermes: the Next Generation of Hermes

Welcome to Static Hermes, an evolution of non-web JavaScript engines. The cornerstone feature is the optional compilation of type-annotated JavaScript into native code, offering predictable performance on par with C/C++. It supports an arbitrary mix of native and interpreted code, both typed and untyped. Optional 'unsafe' language extensions enable direct manipulation of native types and APIs, reducing the need to shift to C++ and allowing for a predominantly single-language codebase. These advancements merge native-like power with the flexibility and convenience of JavaScript. We will explore how Static Hermes may redefine our interaction with React Native and shift the paradigm of JavaScript engines

A Story(book) About Testing

During this talk I’m going to dive into what Storybook is and how you can use it for UI development, testing, and documentation. I’ll go through examples of how you can use storybooks capacity to isolate a component, to import stories into tools like Jest, Testing Library, Puppeteer and Cypress to save you time and maintenance work. I’ll also show you how you can easily use it for, the often forgotten, visual regression and accessibility testing.

Hermes Hacking: Demystifying JavaScript Engines

To many JavaScript developers, JavaScript engines seem like black magic. But they really aren't! They're just programs, like anything else, and you too can understand at a high level how they work, and even contribute. Let me demystify Hermes, and explain to you how its pieces — bytecode, interpreter, garbage collector, hidden classes, and more — all fit together to run your React Native app. We'll also take a look at Hermes's C++ codebase, and make a few changes, and compile it!

The Invisible Architect

As app developers, builders, software architects and designers, we’re used to shape things the way we like. Bend the code to our reality. Often believing we have full control over our creation. But reality is much more complex. Reality means talking to other people, communicating needs and ideas. I’m gonna show you how this communication shapes and designs your products and code, how React fits into this picture, and how to take Conway’s law to your advantage.

From Company to Community: How Expensify is Building Bridges with Open Source and React Native

Expensify's mission is to ""Live Rich, Have Fun, Save the World"", and at a high level that means building a community of people who come together to solve humanity’s urgent challenges. This guiding principle has informed the decision to rebuild Expensify's product as a next-gen collaboration tool, from the ground up with a fully open-source front-end. This approach gives us access to specialized talent, enables us to scale up our engineering capacity without expanding the internal team, and ultimately preserves Expensify's tight-knit culture, keeping us laser-focused on our long-term vision. In this speech, we'll take a tour of Expensify's open-source contribution program and demonstrate how the company engages a global network of contributors to build features, fix bugs, and ultimately build a better product. Our commitment to communal ownership of our dependencies, and the drive to build up the entire React Native community, ties into our long-term goal to build a community that empowers people to ""Get Shit Done."" We'll discuss in detail how the program works, including the various roles we’ve made available for external contributors, how they can get paid to contribute, and some of the lessons learned along the way. Join us as we explore how Expensify is building bridges with open-source and React Native, and how this approach aligns with our mission to make a positive impact on the world.

Speaker BIO:

I'm a Full Stack developer at Expensify, and I've helped build our open-source program since it's inception. I spend a huge portion of my time working with developers from all across the React Native community to help us build our product and, importantly, to improve our dependencies.

Feature driven design – microfrontends’ best friend (on the example of the Chase UK app)

Over the last few years the idea of creating front-end applications implementing the microfrontends design approach became increasingly popular. Not surprisingly - developing the application in a modular way empowers the teams to work with their own pace and take more ownership of the code they write. It can also significantly speed up the delivery of features across the project, as long as it is implemented well. In the very beginning a lot of React Native projects started off as monolithic apps. Even now, when looking for a starter template for a React Native application, it is likely to come across the examples that suggest dividing the code based on its type - screens, components, hooks, helpers, utils, etc. A division that is perfectly suitable for small projects, but in the long run will not be able to guarantee the scalability of fast-growing ones. One that might result in difficult to detect cyclic dependencies, can delay the release of the product due to a simple defect in one of the packages or forces all the teams to use the same tools and boilerplates. Following the principles of feature driven design can help to take the project one step further, offering the possibility to scale it based on - as the name suggests - the development of the features included in it. Not necessarily features commonly understood in the context of the agile methodology, but the product features - the ones that describe the characteristics of what a particular area in the product (and correspondingly in the codebase) is responsible for.
