From bridgeful, to bridgeless, to Expo Modules and Static Hermes, the landscape of native modules in React Native is ever-evolving. Cross-pollination, however, has always been limited – it is rare for React Native to use native modules from other ecosystems, and vice versa.

In this talk, we introduce Node-API, a popular standard for exposing native APIs to JavaScript in an ABI-stable manner, no matter the engine. Used in Node.js and most other major JavaScript runtimes, it is the ideal technology for sharing native modules cross- ecosystem.

We'll show how it's being used by Microsoft in React Native Windows already, and what it may mean for the future of React Native!

This talk has been presented at React Summit US 2024, check out the latest edition of this React Conference.

FAQ

Node.js native add-ons are native modules that allow Node.js to interact with other technologies, such as SQLite3, through packages written with NodeAPI, which is engine agnostic.

NodeAPI is important because it is a popular, community-driven, de facto industry standard for creating Node.js native add-ons. It supports various languages and offers interoperability between native and JavaScript contexts.

ABI stability is the commitment to backwards compatibility in an application binary interface, allowing you to swap out library versions without recompiling the rest of the app.

In React Native Windows, NodeAPI is used to create an ABI stable API for Hermes, allowing for the use of the latest Hermes version without recompiling React Native Windows.

NativeScript allows for calling native APIs from JavaScript, enabling cross-ecosystem library sharing by providing JavaScript access to platform-specific SDKs like iOS and Android.

ABI safety allows a binary to be used in an app without recompilation, regardless of build mode, compiler, or language, ensuring efficient integration and execution.

Node.js native add-ons provide the ability to perform native operations from the JavaScript side, enhancing flexibility and performance in application development.

Future developments include upstreaming NodeAPI into Hermes, supporting Node.js native add-ons, and completing the official ABI stable Hermes API to improve module distribution.

Cross-ecosystem collaboration benefits from NodeAPI by enabling the reuse of libraries and technologies across platforms, reducing redundancy and fostering innovation.

Callstack

React Server Components (RSC) offer a more accessible approach within the React model, addressing challenges like big initial bundle size and unnecessary data over the network. RSC can benefit React Native development by adding a new server layer and enabling faster requests. They also allow for faster publishing of changes in mobile apps and can be integrated into federated super apps. However, implementing RSC in mobile apps requires careful consideration of offline-first apps, caching, and Apple's review process.

This Talk is about the development of MDX, a combination of Markdown and JSX, by a freelance full stack JavaScript developer. MDX is a powerful technology that allows for the creation of interactive content within blog posts and supports React components. The speaker developed RnMDX, a proper and polished MDX library for React Native, which can be dropped into any React Native app. RnMDX provides solutions for common issues with Markdown content in React Native and allows for the rendering of MDX content into native views. Bringing MDX into native apps is now easier, and it can be used for various purposes, such as serving the app layout from a CMS or creating interactive online magazines or blogs.

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

Cecelia Martinez

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.

So you’ve gotten Detox set up to test your React Native application. Good work! But you aren’t done yet: there are still a lot of questions you need to answer. How many tests do you write? When and where do you run them? How do you ensure there is test data available? What do you do about parts of your app that use mobile APIs that are difficult to automate? You could sink a lot of effort into these things—is the payoff worth it?
In this three-hour workshop we’ll address these questions by discussing how to integrate Detox into your development workflow. You’ll walk away with the skills and information you need to make Detox testing a natural and productive part of day-to-day development.
Table of contents:
- Deciding what to test with Detox vs React Native Testing Library vs manual testing- Setting up a fake API layer for testing- Getting Detox running on CI on GitHub Actions for free- Deciding how much of your app to test with Detox: a sliding scale- Fitting Detox into you local development workflow

Building for Web & Mobile with Expo

Workshop

Josh Justice

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!
What's included1. Setting up drawer and stack navigators with React Navigation, including responsiveness2. Configuring React Navigation with URLs3. Setting up React Native Paper including styling the React Navigation drawer and headers4. Setting up a custom color theme that supports dark mode5. Configuring favicons/app icons and metadata6. 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/
