Documentation is often your community's first point of contact with your project and their daily companion at work. So why is documentation the last thing that gets done, and how can we do it better? This talk shares how important documentation is for React and React Native and how you can invest in or contribute to making your favourite project's docs to build a thriving community

We know if we have the fundamental of JavaScript and React knowledge, we can build cross-platform apps. But how many of you have tried out? Learning once and shipping for several operating systems sounds so cool. Don’t you want to experience how it’s easy to transfer your JS
&
React knowledge and powerful built-in APIs to extend your dev skills? In this talk, we’ll see some facts from a developer perspective and a few examples of how you can transfer your JS
&
React knowledge.

You've built a React Native app and now it's time to get it in the hands of your users. If you're used to web, dealing with mobile-specific deployment issues can be a struggle. There are native build hardware and config requirements, signing certificates, app store approvals, app versions, pushing updates, and more. You also have to consider all the tooling options -- do you manually deploy on your own, use a React Native-specific solution, or try to configure web CI/CD for mobile? This crash course will outline the build and ship process and review some common tools in the React Native ecosystem so you can feel confident deploying and get back to developing.

Quick, what is the quickest way to bring your product to the app stores? In today's landscape, trying to get into the app store can mean spending weeks deciding what tool to use and then rewriting your entire app. But the web, and mainly Capacitor, can simplify that. Take your existing web app, add Capacitor to the mix, and you have a native app that's ready for the stores! Let's see what's possible Capacitor and why it can help you ship faster.

It's easier than ever to use JavaScript to build native mobile applications. But for web developers building in the mobile ecosystem for the first time, deploying cross-platform apps built with tools like Capacitor or React Native can be complex. Learn about the mobile-specific deployment considerations through the lens of a web developer, including the key differences between mobile and web, how to develop a deployment strategy, and how to evaluate tooling options.

It’s important to have a frictionless, secure, and performant authentication system for any app, be it web or mobile. In this lightning talk, Itai Hanski covers the importance of authentication and how the Descope team used PKCE to communicate between their React web app and native mobile SDKs.

It's safe to say that a lot of websites and apps these days are heavily reliant on images: product images, avatars, social sharing. With continued technological advances, the variety of device sizes you need to support keeps growing. How exactly are we to make the same page look great and feel performant on both a 16'' MacBook Pro with a retina display as well as a small 5 year old Android phone? We will look at some of the modern approaches to tackle just this problem on web and native - as well as what happens if you don't.

Combining the best of two cross-platform frameworks to build the ultimate multiplatform development experience.

In a nutshell, mobile DevOps best practises for React Native apps, from code to release.

At the end of 2021, we successfully rolled out the New React Native Architecture in the Facebook app. Now, it’s time to empower every React Native developer on the globe to use the New React Native Architecture, both the new Fabric renderer and the new TurboModule system. But migrating an entire ecosystem to a New Architecture is no easy task. To support the whole community in this endeavor, we lined up a set of tools and materials that will help both app and library developers to join us in this journey. In the talk, we will present how the New React Native Architecture looks in the OSS space. We will discuss the impact this will have on developing React Native projects. Lastly, we will cover what we learned from the React Native New Architecture migration at Meta, and how you can tackle your migration in your organization.

In this talk we will see how we can bridge React Native app with commonly used game engine Unity3d for two way interaction between the game and React Native app

How do you start your app on your simulator in the morning? Do you always run react-native run-ios? If so, you might be wasting a lot of time. Let’s check out together what a React Native app looks like under the hood. It will help us to be more efficient on a daily basis. We’ll identify the shortest steps to execute daily actions, like starting our apps as fast as possible (no more unnecessary compilations of native modules!), or dealing with pesky red errors that metro throws at us.

Are you afraid of animations? Well, you shouldn't be, React Native Reanimated got you covered. Your mobile application can share a story through animations, can help users through micro-interactions and differentiate your app from the others.

Developing for each platform individually is so 2010s. These days, with React Native’s component system providing base-level UI constructs, we can efficiently develop for every platform while not sacrificing any particular platform’s uniqueness. Taz will review the approach they’ve taken while developing Guild, and the creation of their Mondrian cross-platform responsive design system as well as how they’ve accommodated the differences in navigational experiences across platforms to accomplish a codebase that can be 95+% shared across every platform.

The React Native new architecture has been "coming next year!" since 2019 - but, this time, it’s actually here! So… what now? What do we actually need to do, to benefit from this all new shiny tech? In this talk, I want to provide some insights and in-depth analysis of the current state of the migration path to the new architecture, to help you and your team evaluate and estimate when and how and how long it will take you to get to the next level!

From the perspective of shipping countless React Native apps over the last seven years, React Native has grown and continues to evolve. There are some major changes coming! Most people have heard of "the React Native bridge", but have you heard of TurboModules, Fabric, and codegen? This talk is a fast-pass to the front of the line in React Native’s upcoming new architecture and how it's going to recast cross-platform development. We will review what you need to know.

The web has several tools to measure performance, but what about us, React Native devs? Have you ever added some optimization in your code (like a memo here and there) and wondered if it had a real impact on performance?
Presenting a Flipper plugin to measure React Native performance, with a concrete case of how we used it to bring our app performance to the top quality.
Bonus: a deep dive into React DevTools flame charts!

You might have heard of React Native's Many Platforms vision, but what about TVs? Find out about the joys and challenges of developing for 7 platforms at once with a single codebase!

At Shopify, the Insights team creates visualization experiences that delight and inform. We've done a lot of great work prioritizing accessibility and motion design for web. Our mobile experiences though, were a bit of an afterthought, but not anymore! In this talk, we'll go through how we created our data viz components library; How we encapsulated core logic, animation, types and even UI components for web and mobile; and also why keeping things separate sometimes is better - to create awesome UX.

Usually creating web and mobile apps require different tech stacks, and it is pretty hard to share code. This talk will show how I added a React web app and a React Native mobile app in the same monorepo using Nx, and how I optimized codeshare between react web app and react native mobile app.

Skin cancer is a serious problem worldwide but luckily treatment in the early stage can lead to recovery. JavaScript together with a machine learning model can help Medical Doctors increase the accuracy in melanoma detection. During the presentation, we show how to use Tensorflow.js, Keras and React Native to build a solution that can recognize skin moles and detect if they are a melanoma or a benign mole. We also show issues that we have faced during development. As a summary, we present the pros and cons of JavaScript used for machine learning projects.

React Native can be much more than a toolkit for building mobile UIs in JavaScript. We’ll explore how to use features beyond the core library, and use the built-in native module system to integrate AR capabilities into your mobile app.

A group of volunteers all over the world is working on React and React Native apps for the ADHD America program (non-for profit organization). In our work we use Recoil - quite a new React state management tool that looks quite promising. I'll show how we use it in both apps - for web and for mobile and explain why we decided to try it.

How to use MDX in React-Native to great effect and the challenges you didn't know you signed up for.

App development is hard, React and Expo make it easy!
It's never been simpler to build and deploy powerful mobile apps with incredible features to both Android and iOS users all over the world.
We’ll discuss building and deploying mobile apps seamlessly from the cloud using EAS, creating powerful dev clients (like browsers but for mobile app development) for testing your app, pushing OTA updates instantly to users, and much more — no native experience required!

My unpopular opinion is that testing is ... important. How do you test your React Native apps? In this presentation I will show how to run full integrations tests using Cypress while the RN app is running in the browser. This method can cover most of the application's code and be effective at finding logical errors and mistakes when calling the server APIs.

In a world where perpetually confused developers can't quite get their React Native development environments working, new libraries emerge from the ashes of lost productivity: envinfo and Solidarity. Escape the complexity and be part of the wave of teams embracing change to save their projects from themselves. 

Haris is talking about the newly open-sourced library Restyle (
https://github.com/Shopify/restyle
); how it addresses many problems and pain points developers experience when managing evolving styles and theme support (gotta have dark mode!) in a React Native app.

Whenever there's a conversation about working on React Native, versioning and release cycle usually arise as one of the pain points. But why is that the case? How complicated is it to create a new release of React Native? Surely it looks similar to the release process you are using... or not! During this talk I'll walk you through the many steps and complexities involved in publishing a new version or React Native, and I'll challenge one fundamental idea – that 1.0 is the solution to all problems. I hope you're ready, it's going to be wild!

Are you a React Native developer? Have you always been longing for the rich ecosystem of developer tooling that exists for the web in e.g. Chrome and Firefox? Flipper is Facebooks internal, extensible mobile devtool platform, used the mobile devs that work on the Facebook, WhatsApp, Instagram and many more apps.
Recently the React Native and Flipper team have been working hard to add first class support for React Native as well. This means that monitoring network traffic and performance, using the React Devtools, inspecting device and application logs or even debugging JavaScript can now can now be conveniently done using one coherent tool.
And best of all: Flipper is extensible, so let's build our own plugin while at it!

It has never been easier for React developers to build native iOS and Android apps. In this talk, we'll see how quickly you can ship your app with Expo open source tools, Expo Application Services (EAS), and React Native. We'll also discuss some of the recent improvements we've made and what's coming up next.

You want to know if your RN app has the best performance? Check out the slow rendering UI stat on the play store, if your numbers are not so good, come to this talk! I will present Systrace, a tool that can be daunting to use at first glance, but a fantastic tool, once you learn how to master it. I will show how it helped us detect and solve performance issues in our app.

I'm going to showcase the React Native architecture we use in our new mobile app at Product Hunt. What we learned, among the way. How we moved what we know from web to mobile. Topics will be designing reusable React components, GraphQL, routing in the app, application lifecycle, keyboard controls, toast messages, and others.

When we started building the Cleo app, we noticed that a lot of functionality, design and types were shared between web (React)
&
mobile (React Native). We investigated whether these could be shared within the codebase too… join me to find out what we discovered.
