React-Native-Nim – Starter Template for React Native to connect a Nim back end

Something of a common problem in JS&#x2F;TS-land, I&#x27;ve found is that unit tests are expected to be run in a Node.js process. In the past in various projects this approach proved problematic because &quot;environment parity&quot; with the target runtime (browser) couldn&#x27;t be achieved (e.g. no WebRTC[1]). In those projects we resolved this problem by writing our own test runner that could be injected into a headless browser process.So now the same sort of problem has arisen with a mobile device project using react native: I assumed that unit tests would be runnable on a device or at least an emulator, but it seems not (see: https:&#x2F;&#x2F;docs.expo.dev&#x2F;develop&#x2F;unit-testing&#x2F;). Or at least so far I haven&#x27;t found the secret sauce or tool to allow that. Any pointers welcome.[1]Yes there is a WebRTC port for Node that uses an old version of Google&#x27;s C++ library, but it doesn&#x27;t actually work properly.

Ask HN: What should I use to run React Native tests on a device?

I need to use new AlarmKit at expo app, how can I do that? Is there library? https:&#x2F;&#x2F;developer.apple.com&#x2F;documentation&#x2F;AlarmKit

Ask HN: How can I use AlarmKit at expo/React Native?

Best React Native UI resources for creating beautiful apps

After trying to find a ui Library which works which works well with Expo and react native web. I decided to create my own.Cross platform: iOS, Andriod, and the web with Windows and macOS support on the way.Our components are accessible on Native and the web. To achieve web accesibility we use react-ariaThis is what differentiates us even beyond shadcn&#x2F;ui! Our components include extra variants so you can adjust error, loading, borderRadius, and style without writing any extra tailwind.Storybook: We have included a storybook to let you play with all the variants.Tested: We write unit tests for all the components to ensure they are working as expected.Customizable: You own the code and the implementation. You can customize anything you want.Get a live demo with storybook here <a href="https:&#x2F;&#x2F;main--68af7af75f72e5521a7e0f93.chromatic.com&#x2F;?path=&#x2F;docs&#x2F;welcome--docs" rel="nofollow">https:&#x2F;&#x2F;main--68af7af75f72e5521a7e0f93.chromatic.com&#x2F;?path=&#x2F;...</a>

React Native – About the New Architecture

Hi HN! I built Oh Yah! to help my sons (age 7 and 10) stick to daily routines without constant reminders. The core idea: minimal distractions during tasks by locking navigation when a timer is running, plus optional photo-based task completion for accountabilityBuilt with React Native&#x2F;Expo and Firebase. The trickiest part was designing the UX to be simple enough for kids with minimal distractions while giving parents enough control – ended up with a task-definition system that lets parents create weekly schedules with daily toggles instead of duplicating tasks across daysIt&#x27;s on the App Store now after a few months of dogfooding with my family. There&#x27;s a 1-month free trial, then it&#x27;s subscription-based. Would love feedback from other parents dealing with similar challenges

# This is a Expo Framework

Expo is a framework and a platform for universal React Applications. 
It is a set of tools and services built around React Native and native platforms that help you develop, build, deploy,
and quickly iterate on iOS, Android, and web Apps from the same JavaScript/TypeScript codebase.

# Requirements

- Node.js LTS release or greater
- Git
- Watchman for macOS users

# Recommended Tools

- VSCode Editor
- Yarn
- Windows users: PowerShell or Bash via WS

# Installing Expo CLI

```bash
 # install the command line tools
 npm install --global expo-cli
```

## Getting Started 

Create a new app:
At this point we should have Expo CLI installed on our development machine and the Expo Go App on an iOS or Android physical device or emulator.
If not, go back to the Installation guide before proceeding.

# Initializing the project

```bash
# Create a project named my-app.
# Select the "blank" templata when promped
expo init my-app

# Navigate to the project directory
cd my-app
```

First, run the development server:

```bash
expo start
# or
npm start
```
