httpstate

httpstate is the missing reactive layer for all your applications.

Store and retrieve state by binding it to any UUID.

Create interactive experiences with a couple lines of code.

Install from CDN (Script Tag)

<script src="https://cdn.jsdelivr.net/npm/@httpstate/typescript/dist/index.global.js" type="text/javascript"></script>

or import from CDN (ES Module)

import httpstate from 'https://cdn.jsdelivr.net/npm/@httpstate/typescript@0.0.42/dist/index.esm.js';

or install from npm

npm install @httpstate/typescript

and then import

import * as httpstate from '@httpstate/typescript';

Pick any valid UUID v4. You can generate one here.

We'll use 45fb3654-0e92-44da-aa21-ca409c6bdab3 or 45fb36540e9244daaa21ca409c6bdab3 (works without dashes).

Store some data with

httpstate.set('45fb36540e9244daaa21ca409c6bdab3', 'Hi! 👋🏻');

and retrieve it with

const data = await httpstate.get('45fb36540e9244daaa21ca409c6bdab3');

That's it! 🐙

All client libraries support realtime updates via WebSocket. Create a reactive instance bound to a UUID and subscribe to change events:

const hs = httpstate('45fb36540e9244daaa21ca409c6bdab3');

hs.on('change', data => console.log(data));

Any client that calls set() on the same UUID will trigger a change event across all connected instances — across devices, languages, and platforms. The TypeScript client uses a shared WebSocket connection with automatic reconnection and exponential backoff.

Browser and server (node.js, deno, bun) compatible clients.

Use it like useState():

const [state, setState] = useHttpState('45fb36540e9244daaa21ca409c6bdab3');

// state — reactive value, auto-updates on change
// setState(data) — writes data via httpstate.set()
