Five years of React Native at Shopify

Hi HN — we’re Seth and Ayo and we’re building a0.dev (<a href="https:&#x2F;&#x2F;a0.dev">https:&#x2F;&#x2F;a0.dev</a>). a0.dev is a platform built to cut down React Native development time from weeks to just a few hours.We’ve been building mobile apps together for seven years and have had several successes. One thing that’s always bothered us though is how much harder it is to build a mobile app than a website. If you’ve built an app with React Native before you’re familiar with the pains of working with both Xcode and Android Studio, writing tons of boilerplate before you can even start making the app, setting up state management, and of course going through the dreaded app review. We decided to build a platform that would make the app development process faster.We’ve seen the success of new code-gen platforms like v0 and wanted something for React Native that goes further. We built an AI app generator that takes a user&#x27;s prompt and creates a custom React Native app with an instant live preview.Here’s a 5min demo where we recreated the Hacker News UI: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;f3lzBRBUous" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;f3lzBRBUous</a>a0.dev is great for quickly prototyping components and screens in React Native and users are able to copy the code from our generator into their preferred development environment. Our landing page has a couple of example prompts, but we encourage you to get creative when trying it out. We’ve had success generating not only functional screens like an Instagram Feed but also 2d games like Minesweeper or Flappy Bird.Our chat has a “UI Expert” and “Advanced Logic” model users can switch between depending on the task at hand. Users can upgrade from working on a single screen to creating a full app by clicking on the “Need a Full App” button in the top right of the page. This changes the scope from a standalone chat with a single file to a full project that can include multiple chats and files. We launched an IOS app that users can download in order to preview the app on a physical device. We find that many apps look and feel better on a physical device so we recommend trying it out.Our goal is to continue to improve the app generator while adding more features to help developers get their apps to the app store and make money from those apps. The main features on our roadmap right now are a Supabase integration and a “one click submit” button to let developers publish their app to the App Store.There are a few limitations to note. We’re working on releasing our Android app, but Android users should be able to preview their app using the Expo Go App. The app is running React Native Web in the browser so any dependencies that don’t support web won’t work with the web preview but should work on the phone. There are also some dependencies that our system can’t handle because they require native modules that aren’t packaged into our app currently.We hope you guys will check it out and try making an app with a0.dev. We’re available on Discord around the clock to help developers with any problems they may face and want to guide people to actually releasing their app on the App Store. Let us know what features you’d like to see and any problems you’ve faced building apps, we’d love to hear about your experience.Here’s the link again to check it out: (<a href="https:&#x2F;&#x2F;a0.dev">https:&#x2F;&#x2F;a0.dev</a>)We dropped the need to sign up for the first message so you can just jump in and try it out.Looking forward to your thoughts!

For those who have used React Native specifically for iOS long term, how are you finding it?From managing multiple iOS versions and APIs to real-world code-reuse across platforms as well.Lastly, would you still recommend given the React Native team have just announced a new architecture?

Hello HN! I work a lot with React Native and needed an alternative to CodePush because Microsoft will stop supporting it in two months. If you use React Native, you can try RootPush to send updates without going through the App Store&#x2F;Play Store process.

I’m working on a React Native project, and I’ve encountered an error where the app crashes immediately upon launch. It doesn’t seem to give any clear error messages, and I’m unsure of what’s causing this issue.I’ve tried a few common troubleshooting steps, like clearing the cache and rebuilding the app, but the problem persists. I’d appreciate it if anyone could provide some insight into how to resolve this issue or point me in the right direction for debugging.Has anyone faced a similar problem with their React Native app? Any advice or solutions would be greatly appreciated!Looking forward to your suggestions!

Hello There, 
&lt;p&gt;I want to show you guys and get your feedback for my Hacker News client built using React Native.&lt;&#x2F;p&gt;
&lt;p&gt;This maybe a yet another Hacker News client, but there was an inspiration behind building HackerBuzz, and it was &lt;a href=&quot;<a href="https:&#x2F;&#x2F;github.com&#x2F;simonhalvdansson&#x2F;Harmonic-HN&quot;&gt;Harmonic-HN" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;simonhalvdansson&#x2F;Harmonic-HN&quot;&gt;Harmonic-HN</a> by Simon Halvdansson&lt;&#x2F;a&gt;, I saw this app and instantly fell in love with its workings and functionality, and wanted to build something like this by myself, hence started working on HackerBuzz&lt;&#x2F;p&gt;
&lt;p&gt;Both code and app might not be perfect and could have problems(that I would love feedback on), but I&#x27;m feeling good to show my work to you.&lt;&#x2F;p&gt;
&lt;p&gt;Here is the repo: &lt;a href=&quot;<a href="https:&#x2F;&#x2F;github.com&#x2F;ajshrmaofficial&#x2F;HackerBuzz&quot;&gt;https:&#x2F;&#x2F;github.com&#x2F;ajshrmaofficial&#x2F;HackerBuzz&lt;&#x2F;a&gt;" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;ajshrmaofficial&#x2F;HackerBuzz&quot;&gt;https:&#x2F;&#x2F;githu...</a>, and apk is also available at release section.&lt;&#x2F;p&gt;
&lt;p&gt;Start the repo if you like it, feel free to give suggestions.&lt;&#x2F;p&gt;
&lt;p&gt;Thank you all ;)&lt;&#x2F;p&gt;

# 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
```
