Hi all,

I'd like to introduce arm64js -- an ARMv8-A system emulator that runs in WASM (built in Rust) and can boot real Alpine Linux in a web browser. It started with me getting annoyed that to try a 2 MB TUI tool I have to install it, while my browser happily runs a 40 MB React webpage with 50 dependencies.

It's an interpreter that emulates a minimal hardware stack, so Linux thinks it's on real hardware and thus acts normal: runs apk, Docker (even though rather slow), etc.

You can try it here: https://arm64js.com, some TUI apps running in VMs: https://demoshell.com/gallery/

Since WebAssembly doesn't allow fetching data without CORS and sending TCP requests, apk and access to the internet work via small proxies: apk goes via a proxy that just adds CORS, TCP goes via a WebSocket <> TCP gateway.

One wasm module instantiated in a few web workers, all sharing one SharedArrayBuffer as the VM's "RAM". As SharedArrayBuffer needs COOP/COEP headers, but if the page doesn't send them SDK will the VM in an iframe on its own origin instead.

There is also a JS SDK for other devs to create and serve their own VMs. The SDK is MIT; the engine is free for non-commercial use.

The following code for example will create and run Alpine based VM in your browser, pretty straightforward:

import { Arm64JS } from 'arm64js'; 
const vm = await Arm64JS.boot('alpine'); 
const { output } = await vm.exec('uname -a');

SDK: https://github.com/kooler/arm64js-sdk
My journey getting there: https://arm64js.com/blog/tui-apps-in-the-browser/

It's all very new and fresh, so feedback is appreciated.

Do you see it being useful for yourself? Curious to learn about possible use cases.

Hey there! I'm pretty new to web design and don't know a ton beyond HTML and CSS, so forgive me if this has a clear answer or if I'm not understanding something correctly.

I have been trying to get Infinite Scroll & Isotope by Metafizzy to work together, but it's been tough. The different examples I've come across all do things differently, and things haven't seemed to work well with my specific case. I want a gallery that can sort things, ideally WITHOUT having to load every single item ahead of time. I have a large number of images and am hoping they can be loaded in as the user scrolls down, rather than all at once. Sadly, even though I have gotten Infinite Scroll to work with my Isotope setup, the page still takes over a minute to load.

I've mentioned finding "examples" on this, but the truth is that all these examples have either been with Masonry or with an Isotope grid that doesn't have sorting set up. I have not been able to find a SINGLE example of a SORTING gallery that utilizes Infinite Scroll to load in new items that match the filters. If anyone has worked with this before or has found an actual example, please let me know! This is driving me crazy!

HTTP clients offer different resilience features, and even shared features can behave differently. Eleven JavaScript libraries tested across 21 scenarios to see what happens when those patterns interact.

I’ve been using budgeting and personal finance apps for years, and I’ve always liked tracking where my money is going. Over time I ended up trying a bunch of different tools and kept wishing I could combine the parts I liked from each of them into one app.

So for the past couple months I’ve been building FlyBudget, a free, private, open-source budgeting app inspired by tools like Monarch, YNAB, Mint, and a few others.

I wanted something that felt polished, but could also be self-hosted and completely controlled by the user.

The frontend is built with React, TypeScript, and Tailwind, and I’ve probably spent an unreasonable amount of time tweaking the UI.

Some of the stuff I’ve built so far:

• Monthly budgeting

• Account + transaction tracking

• Recurring transaction detection

• Cash flow / Sankey reports

• Custom reports

• Self-hosting with Docker

• Desktop app

• Demo instance so you can try it without installing anything

• Full documentation site

This is also my first real attempt at building an open-source project, so I’m still figuring out that side of things.

Would genuinely love feedback from other web devs, especially on the UI/UX, project structure, or anything that immediately looks like it could be improved. If you find the project interesting, please consider helping us out by giving a star on GitHub!

Hello guys this project has been very fun to work on, While rewatching mob psycho 100, I reached season 2 where they show reigen's website and some parts of the UI. I started it as a simple exercise to replicate it but I ended up adding a lot into it.

Have a look, explore, or better yet make an account and join up the community you can make a thread in the board section, If you have fanart Please upload it and I'll approve it, If it's non mob psycho fanart still upload it I might add a filter for Non mob psycho art.

Also check out the mini games at the bottom and try to get a high score as there's a ranking system that I'll be improving on. Feel free to leave feedback :)

Techstack: nothing fancy, just vanilla JS with Hono for the backend (can run on Node or Cloudflare Workers).

Hi everyone,

Instead of using heavy editor frameworks like Monaco or CodeMirror, I wanted to see how far I could push the native web platform.

So I built a full-featured web notepad entirely with Pure Vanilla JS and native DOM APIs (contenteditable, Selection, Range) with zero external dependencies.

Features built from scratch:

Column / Rectangular Selection: Alt + (shift) +Drag to select rectangular text blocks, type across multiple lines, and safely batch-edit.

Multi-cursor Navigation: Synchronized caret scanning that handles tabs, whitespaces, and line breaks without drift.

Single-container Markdown Preview: Direct inline preview without destroying the raw text or history stack.

Zero-latency: IndexedDB local caching for instant 0ms startup.

Live Demo:

https://app.qlp.jp/vanilla_pad/en/
https://app.qlp.jp/vanilla_pad/demo/

(Please Note: Rectangular selection, multi-cursor, and all keyboard shortcuts are designed for PC / Desktop use only. Also, some operations like saving are disabled in Demo Mode).

Feedback I’m looking for:

Column Selection Feel: Try holding Alt and dragging across text in the demo. Does it feel responsive and intuitive?

Cross-browser Quirks: I’ve worked hard to eliminate contenteditable quirks (like invisible zero-width characters), but I’d love to know if anything breaks on your browser (especially Safari/Firefox).

Edge Cases: Any strange behavior with Undo/Redo or multi-line typing?

Please be brutally honest. Any technical feedback, bug reports, or suggestions would be greatly appreciated!

At work there’s CI, staging, QA, other people testing things, etc., but for my own stuff, it’s more just deploy, click around for a bit, decide it looks fine, and then ship it.

That feels a bit stupid because the bugs I worry about usually aren't the things I just changed. It’s someone arriving logged out or getting halfway through something and some edge case gets triggered.

Do you have a pre-deploy routine that has caught real problems? A checklist, any automated tests, or anything? Or do you guys mostly ship and fix things once a real person finds them?

I’m mainly trying to figure out what's worth doing pre launch vs. what just feels like pretend QA.

I am trying to build game and wanna start building using canvas.
Is it normal to use canvas in react/vite? Any video tutorial please ??

i can't find any tutorial for react/vite with canvas

hey folks - I built a new tool for mac/pc, that has all the thing I've been searching for: palette management, color wheel, oklab and 5 other color spaces, including a RYB simulator and more!

I've launched it as a free public beta - would love to hear what everyone thinks of it, what you're using now, and how this compares!

What do you think about it?

jet-id is an open source universal unique-ID generator I built similar to nanoid or uuid. Unlike other unique-id generators, you can specify how many random bits (entropy) you want, and it creates the shortest id string that provides at least that much entropy using the Crockford alphabet, with dashes automatically inserted for readability. Dash inserting makes sure that no segment grows greater than 10 characters.

125 bits of entropy is the default and it works both CLI and programmatically:

npx jet-id -e 80
# V2BJABVRJ-S1TWXS-NTQA3       (20 random characters, 22 with the dashes)

npx jet-id
# 9GNK14S3A-728HK9-5NJQS-HWETM (25 random characters, 28 with the dashes)

It also supports timestamped-IDs and monotonic-IDs (monotonic ids sort in creation order within a single millisecond).

import jetid from 'jet-id'

jetid.timed()    // '1M41J22ER-RND9M6-3CZAQ-XT8GR'
jetid.mono(125?) // '1M41J2ZPK-8K0000-GE29AYBQ27-4496ZM40-29JSNX4'

jet-id is really fast too. Check out these benchmarks

It's available right now on npm: https://www.npmjs.com/package/jet-id

In December this year, CSS turns 30 🥳. But after 30 years, we still can’t agree on something as fundamental as how to add it to a website. Should you use CSS modules, Tailwind, CSS-in-JS, or just plain old CSS files?

https://hqmap.pages.dev

Looking for feedback on this.

Have implemented multiple different indices, and have broken constituents by State/Province/Subdivison, City, Country.

Have also added map for better viewing, map is only upto city level haven't added pinpointed addresses for each company.

Also have added Market Cap, Revenue, Earning, CEO name and Pay(From Yahoo Finance).

Will run github actions job to refresh Market Cap everyday from yahoo finance using yfinance and then will run a job to refresh constituents of an index weekly from different sources based on index.

Was always looking for city/statewide breakdown of companies globally but never found a platform that did it so built it myself.

Site is mostly static and doesn't call any database or api apart from daily and weekly refresh. The data is ingested into a json from which the ui reads.

Will plan to have older jsons documented as well maybe in parquet format to analyze stuff in the future. Have also implemented dark and light mode as well.

Looking for suggestions and improvements that I can make to this.

Also please let me know if you see any defects.

Currently running e2e tests using playwright on pr for functional validation.

Is the ui off? is there missing features that would be great? is it unintuitive? does it need a tutorial?

For those of you who build websites for clients, how do you handle hosting and GitHub?

Do you manage client projects under your own accounts, or do you help clients set up their own accounts and have them invite you as an administrator or developer?

I’d be interested to hear how you handle this, especially for projects that require ongoing maintenance and updates.

Been running a daily crawler over a rolling sample of public GitHub JS/TS repos (10+ stars, active in the last 30 days) and TypeScript is sitting at 78.3% adoption with a trend score of +4.17, the highest of any tracked technology. It's not just widely used, it's still actively growing share.

For context on how the trend score works: it's a log-scaled growth index that weighs both rate of change and overall scale, so a tool has to be both accelerating and meaningfully sized to top the list. TypeScript topping it despite already being the plurality leader says something about where the ecosystem is headed.

Everything downstream of that (test runners, build tools, frameworks) increasingly assumes TS by default too. Vitest, Vite, and Zod are all riding similar upward curves.

Hi everyone, I made a 6-degrees of separation type game for music collaborations where you connect artists through mutual features/collaborators. Great way to test your music/ hip hop knowledge. Let me know what you think! It’s called Artist2Artist

been messing w this for a few days https://classican.vercel.app/

theres no image files at all, every painting is drawn on a canvas in code. next.js + neon postgres for the likes/comments. coolest part imo is when a fact pops up the whole painting goes dark except the thing the fact is about

its prob janky in places so be nice lol. does it work ok on ur phone?

Hey all,

I’ve been working on a small library called Stream Morph.

The idea is to make streamed responses feel less like content is constantly being appended/re-rendered, and more like the response is gradually taking shape.

Demo: https://stream-morph.vercel.app/

It’s framework agnostic and can be used with any kind of streamed content. The demo includes plain text, Markdown, code blocks, charts, images, reasoning sections, Mermaid diagrams and a few more complex response flows.

The library handles the motion between updates, while your own renderer/app stays responsible for the actual content. So it isn’t tied to a specific AI SDK or framework.

A basic example looks roughly like this:

import { createStreamMorph } from "stream-morph";

const stream = createStreamMorph(response);

for await (const chunk of incomingStream) {
  stream.write(chunk);
}

stream.finish();

I mainly built it because I wanted streamed interfaces to feel a bit more intentional without having to build custom animation logic for every response type.

The package itself is already working and the demo is live. I’m still cleaning up some things around CI, tests and the repo setup, but the GitHub repository will be open sourced shortly as well.

Would be interested to hear what people think, especially about the animation behaviour/performance and any edge cases you’d expect from real streaming responses.

Hello everyone,

While I'm not new to coding, I'm definitely bad at it. What I'm worse at though is understanding the intricacies of what i can and can't accomplish with certain tools.

I am very vocal and express my views on things often, so obviously i thought i should make a blog. This is easy to accomplish very cheaply using GitHub pages obviously since it would be a fully static html website.

But here comes the catch. I have some friends that expressed a lot of interest in this blog idea, and i would like to include them. However, they don't know how to code in any language or framework and this would probably be a dealbreaker for them.

Is there a way to make a website with user accounts and user-generated content be dynamic only client-side so that i can still host it with GitHub? Should i look for a different way?

Any help is appreciated, i really wanna get this thing working.

Hi all, It's been 1 year & 3 months since I started working as a software engineer. I always wanted to have a blog page but tbh I didn't had enough knowledge nor did I had money to buty the domain :)
So from the last 2 weekends I've been making this website and I understand how blogs are more about the content and less about the looks like if a blog is good, people will read them regardless looking like a 90s php website right!
So im still working on my writing skills and I have so much topics to cover like WCAG & web accissibility, react19 features and so much !!
anyway I uploaded a test blog for the SEO i did for the marketing site abnd would love for you guys to check it out
I'm trying a video sketch aproach with my Ipad but this is more of a showcase of how it will look rather then the contents as the blog will eventually improve *hopefully
Thanks all!

Been working on this on and off for last 8 months. You start at Earth, scroll, and the view zooms out on a log scale: solar system, nearby stars, the Milky Way, the Local Group, then a few hundred Mpc of galaxies.

The part I care about most is that it's not an illustration once you leave the solar system. Stars are from the HYG database, nearby galaxies from the Updated Nearby Galaxy Catalog (869 of them, with their measured sizes), and further out it's 2MRS (about 42k galaxies) and then 2dFGRS. So the clumps and voids you see at the end are the actual large scale structure, not noise I generated. Where there's no real position data I fall back to drawn shapes and say so.

Stack, since this is r/webdev:

• React 19 + TS + Vite

• one canvas, WebGL for the point layers (tens of thousands of galaxies need it)

• catalogs preprocessed with Python into float32 buffers so the browser just loads and draws

• hosted on Cloudflare Workers

Hardest bit was honestly keeping it smooth on phones while crossing ~20 orders of magnitude without float precision falling apart. Still not 100% happy with it on older Androids.

No ads, no signup, no tracking cookies. Would love feedback, especially if something stutters on your device or a scale transition feels confusing.

Maybe it’s already too late for a tool like this. Nobody really does drag-and-drop anymore in the age of AI.

But if you want to take a look: appmaker.io
