Resource chanx-js: typed WebSocket hooks for React, generated from your chanx server's AsyncAPI

2 Upvotes

Hi all, I want to share a WebSocket library I built, chanx-js. It makes the messages on both ends of a socket typed, keeps the frontend in sync with what the server really sends, and comes with React hooks.

Every realtime feature I built in React ended up the same way. lastMessage was any, so I wrote the message types by hand and found out the backend had changed them only when something broke in production. On top of that I kept rewriting the same reconnect logic and the same switch over message types in every project.

How it works, in three steps: `

  1. The server declares its messages and handlers. Here with chanx-js on Node:

​

const Chat = defineMessage('chat', z.object({ text: z.string() }));
const Notice = defineMessage('notice', z.object({ text: z.string() }));

const chat = consumer('/ws/chat/{room}', {
  name: 'chat',
  groups: (conn) => [`room.${conn.params.room}`],
}).on(Chat, { output: Notice }, (m, ctx) =>
  ctx.broadcast(Notice.create({ text: m.payload.text })),
);
  1. The server publishes those as AsyncAPI, and the CLI turns them into a typed channel:

    npx @chanx-js/codegen http://localhost:8000/asyncapi.json # writes src/generated

    // src/generated/channels.ts export type ChatToServer = ChatMessage; // { action: 'chat'; payload: { text: string } } export type ChatToClient = NoticeMessage; // { action: 'notice'; payload: { text: string } } export type ChatReplies = { chat: NoticeMessage };

    export const chat = defineChannel<ChatToServer, ChatToClient, ChatReplies>()({ name: 'chat', address: '/ws/chat/{room}', });

  2. Your component uses that channel with useChannel:

    import { createClient } from '@chanx-js/client'; import { ChanxClientProvider, useChannel } from '@chanx-js/client/react'; import { chat } from './generated';

    const client = createClient({ baseUrl: 'ws://localhost:8000' });

    function ChatRoom({ room }: { room: string }) { const { status, messages, send } = useChannel(chat, { params: { room }, buffer: 'all', });

    return ( <> <p>{status}</p> {messages.map((m, i) => ( <p key={i}>{m.payload.text}</p> ))} <button onClick={() => send({ action: 'chat', payload: { text: 'hi' } })}> Send </button> </> ); }

    root.render( <ChanxClientProvider value={client}> <ChatRoom room="lobby" /> </ChanxClientProvider>, );

params must have room because the path does, m.payload.text is a string, and send({ action: 'chat', payload: { txt: 'hi' } }) fails to compile. When the backend changes a message, you regenerate and TypeScript shows every place to fix.

What else it gives you:

  • const reply = await request({ action: 'chat', payload: { text: 'hi' } }), with the reply typed from ChatReplies
  • Reconnects, and topic subscriptions (room:lobby, ...) restored after a reconnect
  • lastMessage for the latest message, or an on map with callbacks that don't re-render, and batch: 'raf' for busy streams
  • The server side too: one validated handler per message type, AsyncAPI docs generated from the code, broadcasts across instances through Redis

The backend needs to be a chanx server, since the client relies on its message format and the AsyncAPI it publishes. That can be chanx-js on Node (ws, Express, Fastify, Hono, NestJS), Bun or Deno, or chanx on Django and FastAPI, the Python version I started with.

It's still new on the JS side, so if you run into any problem or have ideas to improve it, please open an issue or a discussion. Stars and PRs are welcome too.

Show /r/reactjs Build a functioning component to edit and save real Excel files

1 Upvotes

I was building a web app and wanted Excel files to live within it and be fully modifiable / saveable, but couldn't find anything open source that fully fit the bill. I ended up building the repo below.

Basically full Excel functionality in our React app including:

  • Import .xlsx and csv file, export to .xlsx
  • Fully preserves existing Excel formatting
  • Real-time calc that's a heavily modified fork of ironcacl
  • Formulas and calculations
  • Multiple worksheets
  • All the formatting options you'd use on day-to-day basis
  • Fully open source

Show /r/reactjs Built a real-time 3D Cyber Command Center with React and CesiumJS — handling state syncing across dynamic WebGL layers

0 Upvotes

Hey everyone,

I built an interactive 3D tactical command center using React and CesiumJS to track real-time global telemetry feeds.

Key React implementation details:

• Canvas & WebGL Integration: Synced Cesium's render loop with React state without triggering unnecessary re-renders during high-frequency telemetry updates.

• Custom Hooks: Encapsulated live ADS-B flight feeds, orbital satellite calculations (SGP4), and threat feeds into dedicated streaming hooks.

• Performance: Avoided standard React DOM nodes for map markers; batched updates directly into Cesium primitive collections to maintain a smooth 60 FPS.

• Dynamic Telemetry: Global fiber optic lines, data centers, and live GNSS interference zones rendered dynamically.

Looking for feedback on React state management patterns when handling high-frequency WebGL data streams!

(Live demo link added in the comments below)

Arrivo: loading states for React that play where your content will land, then hand the real elements back

0 Upvotes

Skeleton screens always felt like a guess to me: grey bars in roughly the right shape, then the real content pops in somewhere slightly different.

So I built Arrivo. While loading is true, an effect plays exactly where your content will land. When it turns false, the real elements are revealed in place.

Demo : https://tuancuongpham.github.io/arrivo/ 

Code: https://github.com/tuancuongpham/arrivo

npm i u/brottin/arrivo

import { Reveal } from '@brottin/arrivo';

import { halftone } from '@brottin/arrivo/effects';

<Reveal effect={halftone} loading={isLoading}>

  <ArticleCard post={post} />

</Reveal>

How it works:

  • Your content stays in the DOM, hidden with visibility, so nothing shifts when it lands.
  • Each wrapper gets one canvas overlay. Text lines are measured with Range rects and images are read from the page, so the effect draws the real shape of your content instead of a guess.
  • An effect is two draw functions, idle() and reveal(p). One shared requestAnimationFrame loop drives every instance, off-screen ones pause, and reduced motion turns every reveal into a 150 ms fade.
  • Zero runtime dependencies, about 8.5 KB gzipped for the core and 0.7 to 3.4 KB per effect, tree-shaken.

The 13 effects: split-flap, redacted, quadtree mosaic, CMYK halftone, CRT tune-in, ink (with 8 threshold maps), particle swarm, darkroom, Tetris, fuse (with a Lunar New Year mode), equalizer, thermal and snowfall.

It's 0.1.0, so feedback is very welcome, especially on where you'd actually use something like this and where it would be too much.
