Duck (<a href="https:&#x2F;&#x2F;duck-lang.dev" rel="nofollow">https:&#x2F;&#x2F;duck-lang.dev</a>) is a statically typed, compiled programming language that combines the best of Rust, TypeScript and Go, aiming to provide an alternative for full-stack-development while being as familiar as possibleImprovements over Rust:
- garbage collection simplifies developing network applications
- no lifetimes
- built-in concurrency runtime and apis for web developmentImprovements over bun&#x2F;node&#x2F;typescript:
- massive performance gains due to Go&#x27;s support for parallel execution and native code generation
- easier deployment since Duck compiles to a statically linked native executable that doesn&#x27;t need dependencies
- reduced complexity and costs since a single duck deployment massively outscales anything that runs javascript
- streamlined toolchain management using duckup (compiler version manager) and dargo (build tool)Improvements over Go:
- a more expresive type system supporting Union types, Duck typing and tighter control over mutability
- Server Side Rendering with a jsx-like syntax as well as preact components for frontend development
- better error handling based on union types
- a rust based reimplementation of tailwind that is directly integrated with the language (but optional to use)
- type-safe json apis

Hey HN,About 5 years ago, I built a weightlifting app for 5&#x2F;3&#x2F;1 that got me on the front page of HN [0]. After that, life happened. I had kids and so decided to get a job and put that project on ice. Eventually I grew too disappointed with my job, and decided to try building something again.The biggest feedback I kept getting from users was simple:
“Let me create my own programs.”That’s how Vis started.The initial idea was to create a B2B platform where gyms and trainers could build programs using formulas (e.g., percentages of 1RM) and reusable blocks instead of spreadsheets. I built what I still think is the best workout editor out there, but I quickly found out that B2B sales is hard (or maybe I just suck at it). It also just didn’t feel like a big enough sell for gyms.So I pivoted. I focused on the iOS app for a while [1], and now re-packaged the editor so individuals can use it directly.With Vis Pro, you can:- Define programs using formulas (e.g., 0.85 * SQUAT_1RM, or even better: RPE(8, SET_REPS) * SQUAT_1RM)- Build workouts by re-using pre-defined or even custom blocks- Share your programs and workouts with othersThe core idea is that programs are parametric instead of static. Change your 1RM and the entire program recalculates automatically.You can try it out without an account at <a href="https:&#x2F;&#x2F;vis.fitness&#x2F;pro&#x2F;try&#x2F;create-program" rel="nofollow">https:&#x2F;&#x2F;vis.fitness&#x2F;pro&#x2F;try&#x2F;create-program</a>The whole thing is built with NextJS, using Chevrotain (surprisingly solid) for the formula engine.It&#x27;s been super interesting using Codex since late Dec. It&#x27;s been a huge force multiplier, enabling me to ship really cool features like formula autocomplete and syntax highlighting in a couple of hours. I&#x27;m used to reviewing a lot of code from my time at Google, so that hasn&#x27;t been a problem, but it&#x27;s interesting to feel that the review speed is now the limiting factor. Though the codebase would become unmaintainable real quick without that.The next step is building an MCP server to allow users to create programs using LLMs and have them show up directly in the editor (and your phone).Would love feedback, whether you even lift or not![0] <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=31508009">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=31508009</a>[1] <a href="https:&#x2F;&#x2F;apps.apple.com&#x2F;us&#x2F;app&#x2F;vis-next-generation-workouts&#x2F;id6743175121">https:&#x2F;&#x2F;apps.apple.com&#x2F;us&#x2F;app&#x2F;vis-next-generation-workouts&#x2F;i...</a>

okay, so this is not so big to many of you , but today , i was just bored and tired of doing any marketing , cos nothing seemed to have been working. so i decided to do a search (i searched for quite a number of keywords) like error tracking for supabase , error tracking for next Js , but my saas didnt rank (if you dont know what im building , im working on a dead simple error tracker that notifies you when something breaks in prod, no bloated dashboards or config hell) , i built this cos sentry had too much noise and i just wanted something that lets me know when there&#x27;s an issue in prod.so i decided to do a search on &quot;error tracking for shipfast(by marc lou)&quot; and guess what ?? Bugmail was the first recommended result , now i dont know how this worked, i mean ive done some seo and stuff but i wasnt expecting it , and now i feel like im back , which is funny cos i didnt make a sale , i didnt onboard a new user yet i feel like o have conquered , life of a founder , i guessi just wanted to share this here, also if you have any advice on how to rank higher on GSC and how to nail this marketing thing , any advice or feedback will be valuablein the meantime , incase you want to check out what ive built;you can check it out here ; https:&#x2F;&#x2F;www.bugmail.site

I forked Chromium and went through the plumbing to embed a ReactJS&#x2F;NextJS web app in its Side Panel like OpenAI&#x27;s Atlas browser and Perplexity&#x27;s Comet browser.The Side Panel has access to the browser&#x27;s DOM which you can pass as context to LLMs in your web app. Supports hot reloading for faster development.Hopefully this is helpful for web devs who haven&#x27;t, or don&#x27;t want to, touch C++ and Chromium, but want to build a native AI experience into browsers.

Through taking the excellent CSE 507 class at UW (Solver Aided Programming) I learned about Rosette, a Racket-based programming system that interfaces with SAT&#x2F;SMT solvers.I applied Rosette to the problem of generating autogramic pangrams, aka self-enumerating pangrams: sentences that contain every letter of the alphabet AND describe themselves.The front end (NextJS&#x2F;Vercel) passes constraints to a Dockerized Rosette program hosted on Cloud Run.Feedback and comments welcome! And Happy New Year!

After rebuilding my setup way too many times, I&#x27;ve finally landed on a stack that I don&#x27;t want to change. Took 6 years to get here, so figured I&#x27;d share what works for me.Here&#x27;s where it&#x27;s landed:Framework: Next.js 16 (App Router) React 19. Server Components, App Router for routing.Auth: Clerk Magic links, passkeys, MFA, social logins (Google, GitHub, Apple, etc.), user impersonation. It works perfectly with Next.js.Database: DrizzleORM Type-safe ORM. Works with PostgreSQL, SQLite, MySQL - but personally I prefer PostgreSQL. Drizzle Studio for exploring data, Drizzle Kit for migrations.Local dev: PGlite This one&#x27;s underrated. Full Postgres running locally, no Docker needed.Styling: Tailwind CSS Utility-first, fast iteration.Forms: React Hook Form + Zod Zod schemas validate on client AND server. Type-safe end-to-end.Testing: Vitest + Playwright Vitest in browser mode replaced React Testing Library for me. Playwright handles integration, E2E and visual regression. GitHub Actions runs everything on PRs automatically.Logging: LogTape Universal and unified logging for Browser, server and edge.Monitoring: Sentry + PostHog Sentry for errors (with Spotlight for local dev - game changer). PostHog for analytics and session replays.i18n: next-intl Built-in internationalization from day one. i18n-check catches missing translations before they hit prod.DX tooling:ESLint
Lefthook for git hooks
Commitlint + Conventional commits for consistent commits
Knip for catching dead code
Semantic Release for changelogs
Dependabot for dependencies update
Security: Arcjet Rate limiting and bot protection without thinking about it.I put this all together into a setup I reuse - nothing hidden, everything customizable. If anyone&#x27;s curious, the whole thing is documented here: https:&#x2F;&#x2F;github.com&#x2F;ixartz&#x2F;Next-js-BoilerplateWhat does your stack look like? Curious if anyone&#x27;s using different setups.

Hi HN,I am the solo developer behind this.The Pitch:
It is a card-based resource management game (inspired by Reigns) where you work IT support for a corporation taken over by eldritch horrors. You have to balance ticket resolution, budget, and entropy while dealing with printers that violate causality.The Architecture:
The entire game is built in React&#x2F;JavaScript. Under the hood, it is basically a giant state machine. I chose this stack because it allowed me to iterate quickly on the UI and text-heavy elements, which are 90% of the gameplay. I&#x27;ve published other games that were more run of the mill and made in Godot, but I&#x27;m a full stack developer by day and most of my day-to-day is in nextJS. I just... I just missed easy state work, ok? Don&#x27;t shoot me. I was half afraid that building executables&#x2F;binaries for Steam would be a nightmare but it turned out (after a bit of futzing about with Tauri for linux) to be not too bad.The Build Pipeline (Tauri vs Electron):
Packaging a web app for Steam Deck was the biggest hurdle.Windows: I use Tauri. It is lighter and creates a much smaller binary since it uses the OS webview.Steam Deck &#x2F; Linux: I had to use Electron. SteamOS does not have a reliable pre-installed webview for Tauri to hook into out of the box.The Rig: I build everything using a Docker setup on a Windows machine to handle the Linux cross-compilation.The Data &amp; Feedback Loop:
The web build has seen 10,000+ plays on itch in the last 2 months with a 4.9&#x2F;5 rating.
An additional 3000 players have picked up the demo on Steam since February 1st.
To gather player feedback efficiently at the edge where the player is, I built a custom system directly into the demo:The game client has write-only access to a Supabase project.
An ingame (thematically fitting) feedback form allows the user to fill in purchase intent (0-10), pricing data, and friction points.This pipes directly into a Discord webhook via edge functions and it&#x27;s broadcasted live to the game&#x27;s discord server for everyone to see.
The idea is to let the community decide, by popular vote, what the actual price of the full game will be. Right now price seems to be converging around the 12-13$ price mark.The link above is to the free web build (Itch). I also just released a downloadable demo on Steam today if you prefer a standalone version: <a href="https:&#x2F;&#x2F;store.steampowered.com&#x2F;app&#x2F;4225400&#x2F;IT_Never_Ends&#x2F;" rel="nofollow">https:&#x2F;&#x2F;store.steampowered.com&#x2F;app&#x2F;4225400&#x2F;IT_Never_Ends&#x2F;</a>Happy to answer any questions about the React state management or the Steam Deck build issues.

Hi, I&#x27;m posting Daily Done, a web app for sharing project updates with clients - <a href="https:&#x2F;&#x2F;dailydone.work" rel="nofollow">https:&#x2F;&#x2F;dailydone.work</a>.Give it a try, it&#x27;s completely free right now.Concept - make it easy to share updates, and let clients see them without any friction (no signup required for clients). Clients can also react with emoji and comment.Goals - my day job is making web apps, but I&#x27;ve never shipped a product on my own. With this I wanted to create something that I could actually build, ship, and support end-to-end. So it is pretty simple (maybe too simple?).Tech stack
- NextJS... don&#x27;t hate me. Next has an annoying amount of magic, but I really like using it. Let&#x27;s me use React to generate plain HTML, and sprinkle in client-side JS for interactive bits.
- Sqlite &#x2F; Turso. Local dev without needing docker is really nice.
- WorkOS authkit, instead of rolling my own auth.
- Polar for billing, although billing isn&#x27;t currently active.Challenges
- The classic problem of getting people to try it out.
- Building something completely end-to-end was new for me. For example, setting up the webhooks and coordinating auth and billing isn&#x27;t hard, but took a bit of thought.
- I can&#x27;t design.Learnings
- Maybe don&#x27;t even build in billing, or possibly even auth, until people are trying it out.

I'm bored, what should I build?

Hi HN!I created an ESP32 driven weather display for pilots that looks like a cockpit instrument. The goal was to move METAR off the phone screen and onto the desk where it is always visible. It’s a dedicated, &quot;always-on&quot; desk accessory that fetches real-time aviation weather and renders it onto a high-contrast e-paper display. It also has a quiz mode to help student pilots learn and test METAR decoding.Jumpseaters: Adding Personality to the Data
Raw METARs can be dry, so I implemented a feature called Jumpseaters. These are selectable personality profiles that transform the device into an opinionated flight crew.Instead of just seeing &quot;OVC001,&quot; you might get a report from Downwind Donnie, who sarcastically judges your &quot;personal minimums,&quot; or Checkride Charlie, a virtual DPE who delivers weather updates with the uncomfortable silence. It was a fun to map these &quot;personalities&quot; to specific weather triggers in the firmware.----The Technical DetailsController: ESP32-S3. I chose this for the native USB support and the power efficiency needed for long-term deep sleep.Display: 4.2&quot; E-Paper. It uses an open-source library <a href="https:&#x2F;&#x2F;github.com&#x2F;martinberlin&#x2F;CalEPD" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;martinberlin&#x2F;CalEPD</a>Power: Deep sleep cycles keep the current draw low, allowing it to run for weeks on a small LiPo. I am continuing to optimize the power usage because I feel I can get it to last many months even after the daily screen refreshes.Tech Stack: ESP-IDF&#x2F;C++ for the microcontroller. Flutter&#x2F;Dart for the iOS&#x2F;Android mobile apps. Nextjs for the website and API.---I have learned a lot about hardware devices during this process. It has been fun programming for the E-paper display. It has it&#x27;s own unique challenges because of the nature of the technology (seconds for each refresh vs. refreshes&#x2F;second for traditional screens). I really enjoy when it refreshes.The Kickstarter is live and 38% funded with 15-days to go. One thing I wish I had done a lot more of is prelaunch marketing. Ads now have had good conversion driving to the Kickstarter page, but the volume takes time.On the same prelaunch theme, the other major lesson learned is that I wish I had asked for more feedback publicly (I do have early testers, but all local) and shared more before working on the Kickstarter. Once you say Kickstarter, all the mods put it in the commercial category and don&#x27;t allow posting ANYTHING related to it.Check it out at <a href="https:&#x2F;&#x2F;papermetar.com" rel="nofollow">https:&#x2F;&#x2F;papermetar.com</a> or <a href="https:&#x2F;&#x2F;www.kickstarter.com&#x2F;projects&#x2F;charlie29r&#x2F;papermetar" rel="nofollow">https:&#x2F;&#x2F;www.kickstarter.com&#x2F;projects&#x2F;charlie29r&#x2F;papermetar</a>

Had some friends in the Media Space (think super into cameras, video editing, vfx, etc...) &amp; 3 years ago they asked me to make a simple srt editor. Fast forward 3 years later (&amp; with much more programming skills under my belt) - spent the last 2 weeks rewriting HappySRT to allow media uploads, threads (like chatgpt), transcribe uploaded files w&#x2F; SRT Editing, Translate the transcribed file (also each translation is individually editable &amp; savable), as well as summarize what the video&#x2F;audio is about (it does it via the transcription).I used Appwrite, Deepgram, NextJS Pages Router, OpenAI API, UpliftAI Scribe, and my favorite npm packages to create this: npm i styled-components &amp; npm i styled-iconsLaunching on Play Store soon (I used next-pwa for that, which meant I couldn&#x27;t use turbopack but instead used webpack) &amp; submitted it already for approval, hope it goes well.

# This is a NextJS
NextJS is a **framework for ReactJS**.

Wait a second ... a "framework" for React? Isn't React itself already a framework for JavaScript?

Well ... first of all, React is a "library" for JavaScript. That seems to be important for some people.

Not for me, but still, there is a valid point: React already is a framework / library for JavaScript. So it's already an extra layer on top of JS.

## Getting Started

Create Next App:

```bash
npx create-next-app
# or
yarn create next-app
```

First, run the development server:

```bash
npm run dev
# or
yarn dev
```

Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.

You can start editing the page by modifying `pages/index.js`. The page auto-updates as you edit the file.

[API routes](https://nextjs.org/docs/api-routes/introduction) can be accessed on [http://localhost:3000/api/hello](http://localhost:3000/api/hello). This endpoint can be edited in `pages/api/hello.js`.

The `pages/api` directory is mapped to `/api/*`. Files in this directory are treated as [API routes](https://nextjs.org/docs/api-routes/introduction) instead of React pages.

## Why would we then need NextJS?

Because NextJS makes building React apps easier - especially React apps that should have server-side rendering (though it does way more than just take care of that).

In this article, we'll dive into the core concepts and features NextJS has to offer:

- File-based Routing
- Built-in Page Pre-rendering
- Rich Data Fetching Capabilities
- Image Optimization
- Much More

## File-based Routing

## Learn More

To learn more about Next.js, take a look at the following resources:

- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.

You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js/) - your feedback and contributions are welcome!

## Deploy on Vercel

The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
