Tier0 SDK for TypeScript/JavaScript. Use when building apps or scripts with @tier0/sdk (React, Vue3, Vite, Node): read/write/history/subscribe UNS (Unified Namespace) as a backend data source, manage Flow (Node-RED) resources, publish/subscribe Tier0 MQTT/MQ over WebSocket, or integrate external data through Tier0 OpenAPI. UNS is a data source, not a UI — do not build a UNS tree viewer, topic explorer, or namespace browser. Every topic path must have a Metric/Action/State type folder immediately before the leaf. Not for non-Tier0 brokers/APIs, another named SDK/client, or implementing an MQTT broker.
