@uns-kit/api

@uns-kit/api exposes Express-based HTTP endpoints for UNS deployments. The plugin attaches a createApiProxy method to UnsProxyProcess, handles JWT/JWKS access control, and automatically publishes API metadata back into the Unified Namespace.

uns-kit in context

uns-kit is a batteries-included toolkit for Unified Namespace applications. It standardizes MQTT wiring, auth, config schemas, and scaffolding so you can focus on your API surface instead of boilerplate. The toolkit packages are:

| Package | Description | | --- | --- | | @uns-kit/core | Base runtime utilities (UnsProxyProcess, MQTT helpers, configuration tooling, gRPC gateway support). | | @uns-kit/api | Express plugin that exposes HTTP endpoints, handles JWT/JWKS auth, and republishes API metadata to UNS. | | @uns-kit/cron | Cron-driven scheduler that emits UNS events on a fixed cadence. | | @uns-kit/temporal | Temporal.io integration that wires workflows into UnsProxyProcess. | | @uns-kit/cli | Command line tool for scaffolding new UNS applications. |

Installation

pnpm add @uns-kit/api
# or
npm install @uns-kit/api

Make sure @uns-kit/core is also installed; the plugin augments its runtime types.

Example

import UnsProxyProcess from "@uns-kit/core/uns/uns-proxy-process";
import type { UnsProxyProcessWithApi } from "@uns-kit/api";
import "@uns-kit/api"; // registers the plugin side-effect

async function main() {
  const process = new UnsProxyProcess("mqtt-broker:1883", { processName: "api-gateway" }) as UnsProxyProcessWithApi;

  const api = await process.createApiProxy("gateway", { jwtSecret: "super-secret" });

  api.get("factory/", "status", {
    apiDescription: "Factory status endpoint",
    tags: ["status"],
  });

  api.event.on("apiGetEvent", (event) => {
    event.res.json({ status: "ok" });
  });
}

void main();

Scripts

pnpm run typecheck
pnpm run build

build emits both JavaScript and type declarations to dist/.
