Getting started

Set up access, then publish and consume state with the JavaScript client. This section takes you from a new account to a working publish/subscribe loop.

What you will do#

1. Create credentials — register an owner and save the API key and key pair from the Welcome page.
2. Publish state — define an object and write its first value with the JavaScript HTTP client.
3. Receive updates — configure WebSocket delivery (or read state over HTTP) so subscribers see changes as they happen.

Account → credentials → object + state → delivery / read

The HTTP API is the source of truth for configuration and state. Delivery channels notify consumers; they can always fetch the authoritative value again when needed.

What you need#

Before you start:

• A modern browser (for registration and browser examples)
• Node.js 22.12 or later (for the quickstart scripts)
• A place to store secrets (password manager or local env file — not source control)

You will leave onboarding with four values: owner, API key, public key, and private key. Tutorials and client examples use the owner in resource names (for example simple:counter@YOUR_OWNER) and the API key to authenticate requests.

Recommended path#

Follow these pages in order the first time:

Inside JavaScript, start with Quickstart to create an object and publish state, then Deliver and read state to wire WebSocket updates or HTTP reads.
