Hey notJust Developers,

Callstack and Software Mansion engineers are working on amazing AI tools for React Native apps. The most exciting one is React Native ExecuTorch, which we'll explore today. Let's dive into today's highlights.

1. React Native ExecuTorch - On device LLM 🚀
2. Radon IDE v1.0 released 🔥
3. React Native Sheet Transitions launched 💯

Now, let’s explore each news story in detail.

React Native ExecuTorch - On device LLM 🚀

Before diving into the news, let’s understand a bit about ExecuTorch.

What is ExecuTorch?

​ExecuTorch is a new AI framework created by Meta in 2023. It makes it easy to use PyTorch models (models developed with the PyTorch machine learning library) on different devices, like mobile phones and microcontrollers. This framework allows you to convert models into programs that can run independently without an internet connection. This keeps user data private, saves money on cloud costs, and allows real-time processing.

ExecuTorch is now in React Native 🚀

Software Mansion with Jakub brought ExecuTorch into the React Native world and released React Native ExecuTorch. With just a few lines of JavaScript, now you’ll be able to run AI models (even LLMs - Large Language Models which can generate and understand human languages) directly on your device. One practical use case is offline customer support in the app. To start, just install it in your React Native app using:

# yarn install
yarn add react-native-executorch

# npm install
npm install react-native-executorch

Radon IDE v1.0 released 🔥

In March 2024, Software Mansion launched Radon IDE v0.1 beta, which was previously known as React Native IDE. After 24 beta versions, they finally released the first ever stable version 1.0 last week. In the v1.0 update, they improved the stability of the simulator preview, made debugging better with breakpoints, and enhanced log management 💯.

Before moving on, let's understand what Radon IDE is all about.

What is Radon IDE & Its features?

​Radon IDE is a VSCode and Cursor (an AI code editor) extension that makes your editor a fully featured IDE for React Native and Expo apps. It offers a bunch of cool features:

1. You can run the iOS Simulator and Android emulator directly in Visual Studio Code.
2. It includes a built-in element (component) inspector.
3. You can use VSCode breakpoints for easy debugging in your React Native app.
4. ​Navigation history is easily accessible (supports both Expo Router and React Navigation).
5. It has strong device settings (like changing app font size or updating app localization) and more.
6. It allows you to record (screen recording) what's currently happening on the device preview.

Sounds amazing, right? Why not give Radon IDE a try today?

React Native Sheet Transitions launched 💯

Last week, Saúl Sharma released an awesome library called React Native Sheet Transitions, which quickly went viral in the community after the release post. This SDK enables you to build native-feeling custom transitions of screens & modals with gesture-based interactions. The most interesting part is that it has zero frame drops and even supports Expo Go 🔥.

Features of React Native Sheet Transitions

The most exciting features of this SDK are:

1. Multi-directional dragging support: You can specify in which directions you want to move (drag) the screen (up, left, down, or right).
2. Custom Animation support: You can change how the screen should look when you move it. (e.g., screen transparency and round corners).
3. Built-in Animations: Currently there are two ready-made animations available.
   1. incremental - background screen moves up &
   2. decremental - background screen moves down when you drag (move) the top screen.
4. Custom background with fade effects in Modals: You can set a custom background image or color that fades in when the modal opens and fades out when it closes.

So, why not try React Native Sheet Transitions today? Just install it by:

# yarn install
yarn add react-native-sheet-transitions

# npm install
npm install react-native-sheet-transitions
