httpstate (typescript)

Quick Start

Install

npm install @httpstate/typescript

Import

import httpstate from '@httpstate/typescript';

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

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

Store some data with

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

and retrieve it with

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

You can also get realtime updates

const hs = httpstate('45fb36540e9244daaa21ca409c6bdab3');

hs.on('change', data => console.log(`This will change everytime data is set [${data}].`));

That's it! 🐙
