As React Native is being used to build many large scale mobile apps. It is important to profile performance to ensure a smooth user experience. Previously, Ram had written and spoken about adding instrumentation to understand the performance characteristics of the app. As the next step, he will explore the various optimizations that can be done in this talk. He will focus on the Javascript section, something where there are many more low hanging fruits to optimizie. Starting from React Dev Tools, Ram will look at how developers can leverage their existing knowledge of web performance to attack mobile perf. Ram will talk about understanding SysTrace and Sampling Profilers. He will also debunk common myths like the problems with measuring app performance using Chrome JS profiler, debug versions of the app, etc. In this talk, Ram will plan to outline a holistic approach that can be used to dive deeper into React Native performance.
Ram is an Engineering Manager at Oculus. He was formerly on the React Native team, working on performance and re architecture of React Native.

React empowered us to render user interfaces anywhere – in memory, browsers, mobile devices to name a few. Rendering in memory is cheap and fast compared to runtime environment, so in-memory UI testing libraries emerged. One of the most popular one now is React Testing Library. Soon after it went public, React Native Testing Library was created trying to implement their style of testing for React Native components. And a few months later another one came to light out of the blue, quickly becoming an official one. The community ended up with two almost identical libraries. Sounds confusing, huh? It was! This story is about all this drama, how it eventually turned out, how community and empathy wins, how businesses help sustain OSS, sprinkled with examples of how you can test your React Native components with just JavaScript.

JSON patches can be used over JSON document for persistent storage that opens up the doors for realtime multi-user apps. They are serializable, small-sized, transferable between realms (threads and network); helps in multi-user implementation, easy to version with history (undo/redo), offline first (optimistic updates). Let's use JSON patches with React / React Native to build a framework for real-time multi-user apps.

If we had the ability to read React Native blog posts from the future, it would be as useful as yesterday's lotto numbers. The technology paradigms change often and when you've been developing React Native for years, it's easy to find yourself doing the same old thing. I think the best way to test your practices, is to occasionally push yourself outside your comfort zone. This is my story of writing an app with something new and what I learned.

React Native proves the success of running React other than browsers. The official supported frameworks from Facebook are only iOS and Android. There were some other platforms maintained by third-party developers, but these forks sometimes run with older React Native versions. The main reason is the difficulty to follow rapidly changed upstream code. From the upcoming React Native new architecture, there will be more platform-independent shared implementations and more abstraction layers. Let's see if we could extend React Native to some new platforms benefiting from the new architecture.

Visual Regression tests are essential for any type of UI development. Without it, you might ship an application after changing the looks of one page without knowing that you broke several other pages. If we can easily see the difference you made in UI for every single PR, it can make the life of reviewers and QAs much simpler. But how would we go about making visual regression test with react native projects? In this talk, I will be sharing what me and my team has been using to perform visual regression test on react native projects, including how components will look in light mode and dark mode.

Our understanding of navigation in mobile stems from years of web usage. Our navigation is a tree and a page transition is an action. But this pattern couldn't be further from what is required by modern app UX standards. In this talk we will go through the required changes in our navigation architecture in order for it to reach its full potential.

Ever wondered if your Product Manager is the only pushing for new features without any limits, while you are trying to keep app performance at it’s best? Well, don’t you worry, you’re not alone! Come and learn how to improve your React Native app performance with few simple tricks. In the past 5 years, the Wix mobile app has gone through quite a bit - a brand new look was launched, a large number of features were added in a short period of time, and the number of our users tripled. Unfortunately, one implication of product growth, is a slower performance, especially when it came to things like seamless transition, fluent animations and general slickness of the app. Over the past year, we made a tremendous effort to improve these regressions. Our ongoing efforts have so far resulted in almost 60% cumulative improvement in all performance metrics. In this talk, I’ll deep into all of our secret ingredients for better performance in React Native applications, together with practical examples of: -Improving startup time -Responsive gestures -Preload prioritization Furthermore, I’ll outline some general work we’ve done that led us to these improvements, like the right way to measure and analyse your app performance on production, and how you can implement these tips and tricks.

Feature flags allow development teams to separate code deployment from feature release. It has grown to be an essential tool for testing in production, A/B testing, and controlled rollout. Controlled rollout using feature flags is a way to deliver features to your users safely, but doing it on mobile comes with some challenges. How do you propagate feature flagging configuration to mobile devices that don’t always have a strong network? As a mobile developer, you want to be able to use the latest flag configuration, but you also don’t want to stop someone using the app just because you can’t load the feature flag config. In this talk, we'll start with why controlled rollout is important and how feature flags enable you to do it successfully, then we will talk about mobile specifics, and then a demo with React Native.
