Windows 11 Start Menu Revealed as Resource-Heavy React Native App

Hey Hacker News,I&#x27;m a long-time lurker and wanted to share a project I just finished building.Like many React Native developers, I needed to add marker clustering to a map in my app. The most popular library for this, react-native-maps-clustering, was fantastic in its day but has become outdated and no longer works with modern versions of Expo, React Native, and their dependencies.After hitting a wall of compatibility issues, I decided to take on the challenge of rewriting it from the ground up, focusing on a modern toolchain and a better developer experience.The journey was a lot more challenging than I anticipated. It turned into a deep dive into solving dependency hell with different versions of @types&#x2F;react, wrestling with build tool configurations for pnpm, bob, and ESLint, and ensuring everything was strictly typed with TypeScript. It felt like a classic case of yak shaving, but I was determined to create a solution that &quot;just works&quot; for developers today.The result is RN Super Cluster, a performant, fully-typed, and easy-to-use clustering library for react-native-maps.What it does:
It provides a &lt;ClusteredMapView &#x2F;&gt; component that you can use as a drop-in replacement for the standard &lt;MapView &#x2F;&gt;. Any &lt;Marker &#x2F;&gt; components you place inside will be automatically clustered.Key Features:<pre><code> Modern &amp; Maintained: Built with a modern toolchain and designed to be actively maintained.

 Fully-Typed: Written entirely in TypeScript to prevent common errors and improve autocompletion.

 High-Performance: Uses supercluster under the hood for extremely fast geospatial clustering.

 Spiderfier: At the maximum zoom level, overlapping markers automatically &quot;spiderfy&quot; (spread out on a spiral) so they can be individually tapped.

 Customizable: You can provide your own custom components for rendering clusters, and callbacks for handling press events.
</code></pre>
This was a passion project born out of necessity, and I hope it can save other React Native developers the headaches I went through.I would love to get your feedback, and contributions are more than welcome!GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;suwi-lanji&#x2F;rn-maps-clustering">https:&#x2F;&#x2F;github.com&#x2F;suwi-lanji&#x2F;rn-maps-clustering</a>

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

Hi HN,I&#x27;ve been working solo on a visual builder for React Native apps for the past year.It allows you to:
- Build UI visually with drag-and-drop
- Preview changes in real-time on multiple devices (via Expo Go)
- Export clean, simple Expo&#x2F;React Native code you can run with `npm install &amp;&amp; npm start`The idea is to help developers (or small teams) prototype faster, and bridge design&#x2F;dev handoffs more smoothly.It’s still in early stages, and I’m looking for feedback.1-minute demo video: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;jgI21qXehKA" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;jgI21qXehKA</a>Try it here: <a href="https:&#x2F;&#x2F;clickly.app" rel="nofollow">https:&#x2F;&#x2F;clickly.app</a>Would love to hear your thoughts!- Alexey

Hermes-dec: tool which can disassemble and decompile React Native

Hey HN, Henry and Roman here - we&#x27;ve been building a cross-platform framework for deploying LLMs, VLMs, Embedding Models and TTS models locally on smartphones.Ollama enables deploying LLMs models locally on laptops and edge severs, Cactus enables deploying on phones. Deploying directly on phones facilitates building AI apps and agents capable of phone use without breaking privacy, supports real-time inference with no latency, we have seen personalised RAG pipelines for users and more.Apple and Google actively went into local AI models recently with the launch of Apple Foundation Frameworks and Google AI Edge respectively. However, both are platform-specific and only support specific models from the company. To this end, Cactus:- Is available in Flutter, React-Native &amp; Kotlin Multi-platform for cross-platform developers, since most apps are built with these today.- Supports any GGUF model you can find on Huggingface; Qwen, Gemma, Llama, DeepSeek, Phi, Mistral, SmolLM, SmolVLM, InternVLM, Jan Nano etc.- Accommodates from FP32 to as low as 2-bit quantized models, for better efficiency and less device strain.- Have MCP tool-calls to make them performant, truly helpful (set reminder, gallery search, reply messages) and more.- Fallback to big cloud models for complex, constrained or large-context tasks, ensuring robustness and high availability.It&#x27;s completely open source. Would love to have more people try it out and tell us how to make it great!Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;cactus-compute&#x2F;cactus">https:&#x2F;&#x2F;github.com&#x2F;cactus-compute&#x2F;cactus</a>

It&#x27;s been a few months since Lynx JS (https:&#x2F;&#x2F;lynxjs.org&#x2F;) was open-sourced. It seems to offer a lot with regards to speed, but it doesn&#x27;t use real HTML elements, and seems to cater to the React crowd.Has anyone used it for anything serious, and what are your thoughts? How does it compare to e.g. Flutter, Ionic + Capacitor, React Native etc.?

I&#x27;ve mentioned CareerCupid [0] a few times, a website where people can find out about other potential co-workers and companies that share their values and can be used a some form of screening system without forcing people to apply to a specific position.To help overcome the chicken-and-egg issue, there is something a bit novel: the website integrates with ActivityPub, so you can follow @thecupid@cupid.careers (this is not a Mastodon bot, but a fully-fledged application built on my Django ActivityPub Toolkit [1]), I&#x27;ve made a quick demo [2] about on the last FediForum to show how we can build applications to leverage the existing social graph instead of trying to make the Fediverse grow by re-implementing federated versions of the traditional social networks.When I first launched this, I made a post where I offered a discount for the first companies joining, but it didn&#x27;t get a lot of visibility. Now that we got to the first of the month day and the &quot;Who is hiring?&quot; threads are upon us, I thought it would be a good time to say that the company pages and job listings are also integrated with ActivityPub and I&#x27;ll be offering 3 months completely free for the first 100 people that signup (code HN2025)If you want to try it out, you need to create an account and create a &quot;company page&quot; (<a href="https:&#x2F;&#x2F;cupid.careers&#x2F;company&#x2F;new" rel="nofollow">https:&#x2F;&#x2F;cupid.careers&#x2F;company&#x2F;new</a>), after creating the basic page, you will see the option to complete the subscription. Use the code and you&#x27;ll be good to go.----It works in a similar way as OkCupid used to work: people answer questions and they indicate (a) how they would like other people to respond and (b) how important their answer is to you. By comparing your answers against everyone else&#x27;s, we can create a &quot;compatibility score&quot; that can be a measure of how well you&#x27;d get along with a potential co-worker.Another thing that I&#x27;ve been working on is what I am calling a &quot;Skill Tree&quot;. My plan is to build make it easier for both hiring manager and employees to see what parts of the tech stack are really important vs what can be learned on the job or &quot;adapted&quot; by someone with experience in a related skill. When defining the skills, the same matching algorithm can be applied to score the technical fit.For a (contrived) example: the expectations around &quot;experienced with Python and PostgreSQL&quot; can be quite different if we are talking about a data analyst, or a web backend developer, or a DBA that will need to write PL&#x2F;Python routinely. So the idea here is to have this &quot;Skill Tree&quot; where there are many different root nodes (Software Development, Management, UI&#x2F;UX, System Administrations) and let these skills branch out from these root nodes to make the skill requirements as broad (Software Development -&gt; Javascript) or specific (Software Development -&gt; Javascript -&gt; React -&gt; React Native, or Operations -&gt; Continuous Delivery -&gt; Jenkins) as needed. ThisThere are some other ideas that I&#x27;m considering, like creating a database of issues in open source projects that could be used as part of the skill assessment, a more reliable &quot;vouching&quot; systems where professionals can look at listings and make a referral even when they are not working at the company. But to do any of that, first I&#x27;d like to grow the user base and get more feedback.[0]: <a href="https:&#x2F;&#x2F;cupid.careers" rel="nofollow">https:&#x2F;&#x2F;cupid.careers</a>[1]: <a href="https:&#x2F;&#x2F;activitypub.mushroomlabs.com" rel="nofollow">https:&#x2F;&#x2F;activitypub.mushroomlabs.com</a>[2]: <a href="https:&#x2F;&#x2F;spectra.video&#x2F;w&#x2F;nibHzQxR26zQX1eYkFgygL?start=2m44s" rel="nofollow">https:&#x2F;&#x2F;spectra.video&#x2F;w&#x2F;nibHzQxR26zQX1eYkFgygL?start=2m44s</a>

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;)
```

Hi HN,Went to the Luma ai hackathon.Met a guy who vibe coded a legit app with 0 coding experience - I taught him shortcuts which was quite fun to see him 10x his Cursor productivity.Anyway, this inspired me to vibe code something, so I made this short story generator for my nephew.It takes a profile image, gpt-image-1&#x27;s it into an avatar.Yes I know what you are thinking, privacy! The profile image part is completely optional - you can upload pretty much any image you&#x27;d like, already avatar-ed images work great.Then you can create stories with the avatar as the main character in all the story images.Stories teach a lesson and moral, and are age appropriate.Also threw in some great narration voices since I use Elevenlabs all the time.Nephew&#x27;s feedback is overwhelmingly positive, but he is 1.2 years old so...Hoping to get feedback from folks here as well.Stats for nerds:
Built with:
React Native Expo (first time using Expo - props to them for coming so far)
Supabase (first time as well - love it)
Elevenlabs
gpt-image-1 (i tried over 5 different api&#x27;s for i2i and this one is the best BY FAR)Made with 80% Cursor, 20% by handBare bones story generator MVP was done in an afternoon, more features added over 1.5 months like i2i, narration, auth, iap, etc.First 2 stories are free (24 images), and I put 250 bucks into openai, so it should last a few days. Openai image rate limits are kinda low for my tier, so some images might not generate - if this happens, please let me know so I can add mo money to upgrade my tier.If you encounter any issues or find a bug or have suggestions, please let me know.Free to download in the app stores, <a href="https:&#x2F;&#x2F;www.onceupona.ai" rel="nofollow">https:&#x2F;&#x2F;www.onceupona.ai</a>Give a upvote on Product Hunt if you enjoyed: <a href="https:&#x2F;&#x2F;www.producthunt.com&#x2F;products&#x2F;once-upon-a" rel="nofollow">https:&#x2F;&#x2F;www.producthunt.com&#x2F;products&#x2F;once-upon-a</a>Thanks!

Hi HN,I’m the founder of Newsplash, a lightweight AI-powered news platform that delivers personalized, fact-based daily digests—no clickbait, no paywalled fluff.⸻Why I built it:I found myself spending too much time sifting through sensationalist headlines and repetitive stories across major aggregators. Newsplash is my attempt to solve that: a tool that gives users a fast, trustworthy summary of the news that matters most to them—without the noise.⸻How it works:
 • ~500 articles pulled daily via NewsAPI
 • Deduplicated and cleaned with a readability parser
 • Summarized using GPT-4o (≈90–120 tokens per article)
 • Each user gets a unique daily digest based on topic preferences and feedback (likes&#x2F;dislikes)
 • A built-in GPT chat tool allows users to ask contextual questions like: “Why does this matter for Nvidia’s stock?”⸻Stack overview:
 • Edge Functions: Deno (Supabase) for fetch, deduplication, and summarization
 • Database: Supabase Postgres for articles, preferences, digests
 • Frontend: React + Next.js (web), React Native + Expo (iOS)
 • AI: GPT-4o mini for summarization + article Q&amp;A
 • Reranking: Simple cosine similarity on user feedback vectors⸻What’s live:
 • Web app with personalized digests
 • Feedback loop (like&#x2F;dislike) that re-trains per user
 • Article-level AI Q&amp;A
 • Free model⸻Next up:
 • Expanding digest customization (custom categories, source filters, articles per category)
 • Premium&#x2F; subscription product⸻I’d love your thoughts on:
 • Privacy&#x2F;security best practices around everything. I don’t have a coding background so I have no idea
 • Ideas for building trust and transparency into AI summarizationThanks for checking it out
