Why BigState?

Everything you need to build real-time applications without the complexity

⚡

Latency

ms latency

📈

Throughput

High-volume concurrent publishers and subscribers.

🛡️

Explicit Access Control

Use principals and policies to control which identities can perform actions on matching resources.

📦

Inline and Binary States

Store JSON, numbers, strings, and Base64 data inline, or binary inlined content.

How It Works

Three simple steps to real-time data synchronization

1

Publish

Your backend, device, or service writes the latest object state through the HTTP API.

await httpClient.stateSet(OBJECT_NAME, { value: data });
2

Route

BigState stores a versioned state row and matches the object against configured delivery channels.

// Automatic routing via Delivery
3

Deliver

Configured delivery channels send matching state updates to their consumers.

// Delivery routes matching updates

Simple & Powerful API

Get started with just a few lines of code

example.js
import { BigStateHttpClient, BigStateWsDeliveryClient } from 'bigstate.client.javascript';

const httpClient = new BigStateHttpClient({
	baseUrl: 'https://api.bigstate.dev',
	apiKey: 'YOUR_API_KEY',
});

const LOCATION_OBJECT = 'user:location@YOUR_OWNER';
example.js
await httpClient.objectCreate(LOCATION_OBJECT, {
	type: 2,
	ttl: 100000,
	validity: 60,
	info: { name: 'User Location' },
});
example.js
await httpClient.deliveryCreate('my-delivery', {
	name: 'Location updates',
	objects: [LOCATION_OBJECT],
	type: 1,
});
example.js
const wsClient = new BigStateWsDeliveryClient({
	baseUrl: 'https://ws.delivery.bigstate.dev',
	apiKey: 'YOUR_API_KEY',
});
example.js
wsClient.setDeliveries(['my-delivery']);
wsClient.setMessageHandlers([(message) => {
	console.log('New state:', message.data.state);
}]);
example.js
await httpClient.stateSet(LOCATION_OBJECT, {
	at: new Date().toISOString(),
	value: { lat: 40.7128, lng: -74.0060 },
});
