Liquid Glass View on React Native

Hey folks!I wanted to develop drag-and-drop functionality in my React Native app. After hitting a wall with all the existing options, I decided to dive deep and build a solution from scratch built with Reanimated 3 and RNGH.The result is react-native-reanimated-dnd, a library I poured a ton of effort into, hoping to create something genuinely useful for the community.My goals were simple:Performance: Smooth, 60fps interactions are a must.Flexibility: From basic draggables to complex, auto-scrolling sortable lists.Developer Experience: Clear API, TypeScript, and (I hope!) excellent documentation with plenty of examples. (There&#x27;s an example app with 15 demos you can try via Expo Go – link in the README!)It&#x27;s got all the features I wished for: collision detection, drag handles, boundary constraints, custom animations, and more.You can find everything – code, feature list, GIFs, and links to the live demo &amp; docs – on GitHub.@entropyconquers&#x2F;react-native-reanimated-dndIf you find it helpful or think it&#x27;s a cool project, I&#x27;d be super grateful for a star !I&#x27;d love to hear your thoughts, or even what your biggest pain points with DnD in RN have been. Let&#x27;s make DnD less of a chore!

I made a React Native Drag and Drop library that finally works!

When i finished a major part of my app and needed to build an apk for prod, i had to search online and through the docs for a couple hours and at the end it just gave me a bulky 98mb apk even though my app has less than 5mb of assets and only reacr-native-svg and expo-video as deps and even worse, there&#x27;s no way to configure eas to split the apk by architecture to cut size, i tried building the apk on device using eas build --platform android --profile preview --local and it fails due to some graphql bullshit everytime, i just feel they are pushing apk culture behind and lifting up their aab structure

Why doesn't expo(reactnative) promote APK builds

Hey HN,I&#x27;ve been working on Organize for a few years now, and I figured May Day&#x2F;International Workers&#x27; Day would be a good time to show it off. I&#x27;m here in the comments if you have any questions!Problem:According to recent polls, 70% of American workers support unions [1], and 50% say they&#x27;d join one if they could [2], but only 10% are actually in one [3]. That translates to 60 million US workers who want to join a union but haven&#x27;t yet [4].Solution:Organize is a self-service guide for workplaces that are too small to attract a full-time organizer. 85% of US firms have less than 20 employees [5], which is often just too small to justify the full attention of a professional organizer.Inspired by the winning strategies of veteran organizer Jane McAlevey [6], Organize helps you recruit the support of a supermajority of your coworkers, so that you can crush your certification election and win big when you negotiate your first contract.Tech:Organize is an MIT-licensed React Native client and Ruby on Rails backend that runs on a Raspberry Pi 5. It has a simple deploy system based on Docker Compose for now, but I&#x27;d love to switch to Kamal at some point. PRs welcome!With the exception of a single unencrypted email per workplace organization (Org), all user-generated text within the app is end-to-end encrypted (E2EE) to minimize the value of a data breach. Each Org has its own group key, created by the Org&#x27;s founder and shared through the QR membership codes discussed below.Joining an Org involves scanning the QR membership code of any existing Org member (see [7] for a video). This builds up a web of trust via face-to-face, in-person interaction. However, the QR code really just contains a short-lived JWT and the Org&#x27;s group key. As such, it&#x27;s ultimately possible to invite people remotely by crafting your own JWT or sharing a screenshot of your QR code. Still, the &quot;default mode&quot; of in-person scanning encourages a degree of phishing resistance.Members of every new union must determine what they think is worth fighting for. So Organize has an HN-style discussion tab with upvotes and downvotes to help surface shared grievances and come to a consensus on which demands are most important to each individual Org.Democratic decision making strengthens unions by building trust between rank-and-file members and their officers. So Organize makes it easy to vote on anything. In addition to yes&#x2F;no, multiple choice, and N-of-M voting, Organize also helps Org members elect their officers (e.g. president, VP, treasurer, etc). In addition to their real-world responsibilities, elected officers also act as Org admins within the app. For example certain officers can moderate discussions. This is handy since the E2EE makes it impossible for me to act as a moderator.Lastly, before any new union can become certified by the National Labor Relations Board, its members must affirm that they truly want to be represented by their union for the purpose of collective bargaining. Traditionally this involves dealing with physical index cards or paper petitions and manual data entry. Recently this involves using Google Forms or email (read Gmail) to collect signatures, despite the risk of handing over all this personally identifiable information (PII) to 3rd parties. So Organize makes it easy to sign and collect union cards without giving me any of your PII, thanks to the E2EE.Links:- iOS app: <a href="https:&#x2F;&#x2F;apps.apple.com&#x2F;app&#x2F;organize-modern-labor-unions&#x2F;id6723855445">https:&#x2F;&#x2F;apps.apple.com&#x2F;app&#x2F;organize-modern-labor-unions&#x2F;id67...</a>- Android app: <a href="https:&#x2F;&#x2F;play.google.com&#x2F;store&#x2F;apps&#x2F;details?id=app.getorganize.organize">https:&#x2F;&#x2F;play.google.com&#x2F;store&#x2F;apps&#x2F;details?id=app.getorganiz...</a>- &quot;How to Organize&quot; handbook&#x2F;blog: <a href="https:&#x2F;&#x2F;getorganize.app&#x2F;blog" rel="nofollow">https:&#x2F;&#x2F;getorganize.app&#x2F;blog</a>- Client repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;High5Apps&#x2F;organize-rn">https:&#x2F;&#x2F;github.com&#x2F;High5Apps&#x2F;organize-rn</a>- Backend repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;High5Apps&#x2F;organize-backend">https:&#x2F;&#x2F;github.com&#x2F;High5Apps&#x2F;organize-backend</a>

I am honestly so eager to build an app but I haven&#x27;t got any plan as to what I would build. I&#x27;m thinking that this app should be on mobile so that I can learn React Native. Any tips on anything are greatly appreciated!

What are some app ideas that you think would benefit people on a perosnal level?

Everyone hates production bugs. Users get frustrated. Engineers get paged. Development gets delayed. But what if many of those bugs could be fixed automatically?Enter Paladin, a tool I built that automatically sends you a pull request to fix bugs shortly after they occur.A little over a month ago, I posted my hacky but effective AI setup for fixing production bugs to Reddit (<a href="https:&#x2F;&#x2F;redd.it&#x2F;1jibmtc" rel="nofollow">https:&#x2F;&#x2F;redd.it&#x2F;1jibmtc</a>). 300+ devs messaged me or commented wanting to try it out, so I’ve been spending the past weeks refining it into Paladin, and excited to release it today!How it works:Paladin hooks into your application’s error handling with an SDK, triggering a “run” when an exception is thrown. During the run, Paladin pulls your code on Github and uses LLMs to fix the error, sending you the fix as a PR over Slack in ~90 seconds. Here’s a two minute demo: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;0bm8nq99Nrw" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;0bm8nq99Nrw</a>.In early testing, Paladin solves over 55% of real production errors on the first try and makes useful progress on many others. It’s able to do well by supplying deep context to the LLMs: the stack trace, execution state, repo code, and more. When it works well, it allows you to fix bugs more quickly, meaning less downtime for users and saved engineering time.Eliminating context switching has been an unexpected win for me, because I work best in long, focused stretches. When a bug hits affecting real users, I have to drop everything mid-feature to stash changes, debug, and mentally shift contexts, and then try to return. I’ve found PR reviews and tweaks to be much less disruptive.Getting started (Free, no card required)
1. Sign up at <a href="https:&#x2F;&#x2F;app.paladin.run&#x2F;signup" rel="nofollow">https:&#x2F;&#x2F;app.paladin.run&#x2F;signup</a>
2. Follow instructions to connect your Github and Slack (or just email)
3. Choose and install the correct SDK into your app
4. Configure to send errors to Paladin
5. Done!Paladin supports React, React Native, Laravel, Flutter, Django, Node, Next, Vanilla Javascript, Express, FastAPI, PHP, Vanilla Python, Nest, Vue, Android, iOS, Rails, Flask, and many more thanks to Sentry’s MIT licensed client SDKs (your errors do not go to Sentry, they are just used to capture errors). If you have a client and server, I’d start with your server.Notes on privacy, performance, and future plans below:Paladin will never abuse repo access for any type of training or sharing, and only pulls it for making fixes. An LLM provider (Google&#x2F;Anthropic&#x2F;OpenAI) processes part of your code, so if you can’t use tools like Cursor&#x2F;Windsurf, you probably can’t use Paladin.On performance, my personal set is admittedly very limited, but I think the performance makes sense to me given current bests on benchmarks like Aider Polyglot and SWE-bench Verified. I’d expect these numbers to get much better as models progress. I’d also expect Paladin to fall short where current frontier LLMs do: uncommon frameworks, libraries or languages.In the future, I am planning on having two usage options:
- Free: if you bring your own OpenRouter API key
- Paid: if Paladin pays for the model costsReally looking forward to hearing feedback and ideas!

In the recent months &#x2F; weeks I&#x27;ll ready so many headlines about &quot;AI will be able to create whole applications easily&quot;, &quot;No coders needed, everything will be AI&quot;, &quot;Vibe Coding is the future&quot; so I thought I&#x27;d try it out.
I&#x27;ve been building React Apps and TypeScript Backends for a few years so I am not a total newbie. I wanted to create a simple React Native App which has a Bottom Sheet and display a map.
Already at the first step - creating the map - ChatGPT o3 gave me completely invalid code. It used a pretty old version of the library which wasn&#x27;t compatible with the latest react release. It also got few things with expo vs. &quot;pure&quot; react native wrong. Sometimes the code it threw at me included unused styles or variables.Am I missing something? How are people seemingly building complex applications if the models struggle with basic things like keeping up to date with releases? What are your experiences?

I built WanderEye after getting frustrated while travelling and not knowing anything about what I was looking at. With WanderEye you can point your camera at any monument&#x2F;landmark and get instant historical context.Technical details:
- React Native for cross-platform development
- AI algorithm for landmark recognition 
- Capability to create personalized travel plansStarted with zero mobile dev experience 4 months ago. The biggest challenge was developing an algorithm that works globally while maintaining high accuracy.Currently live on iOS, working on Android version.Would love feedback on the technical approach and UX decisions.

Hey HN,I built [*WinUp*](<a href="https:&#x2F;&#x2F;github.com&#x2F;mebaadwaheed&#x2F;winup">https:&#x2F;&#x2F;github.com&#x2F;mebaadwaheed&#x2F;winup</a>) — a modern GUI framework for Python that works like React or Flutter, but with native Qt widgets under the hood.### Why I made this:
Python has great libraries for data, backend, scripting… but most GUI libraries are either:
- Verbose (Tkinter, PyQt)
- Old-school imperative
- Slow or bloated (Electron)WinUp gives you:
- Declarative UI with `@component` functions
- Hot reload for real-time editing
- CSS-like styling system
- State binding with `State()` like React
- Native rendering via PySide6### Example:
```python
import winup
from winup import uidef App():
 # 1. Create a state object with an initial value.
 counter = winup.state.create(&quot;counter&quot;, 0)<pre><code> # 2. Create the UI widgets.
 label = ui.Label() 

 # 3. Bind the state to the label&#x27;s &#x27;text&#x27; property.
 # The lambda function will re-run whenever the counter changes.
 counter.bind_to(label, &#x27;text&#x27;, lambda c: f&quot;Counter Value: {c}&quot;)

 def increment():
 # 4. Use the state object&#x27;s methods to update the value.
 counter.set(counter.get() + 1)

 return ui.Column(children=[
 label,
 ui.Button(&quot;Increment&quot;, on_click=increment)
 ])
</code></pre>
if __name__ == &quot;__main__&quot;:
 winup.run(main_component_path=&quot;file_name:App&quot;, title=&quot;New State Demo&quot;)
```

# 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
```
