@openmini/runtime

The mini-app side of OpenMini: a typed, zero-dependency client for the bridge a host embeds you in.

npm install @openmini/runtime

import { mini } from "@openmini/runtime";

await mini.storage.set("greeting", "hi");
await mini.ui.showToast({ message: "saved" });
const info = await mini.system.getInfo();
const data = await mini.host.invoke("getCart", { userId: "u1" }); // host-defined

• Full surface: bridge API reference
• Wire protocol (source of truth): specs/bridge-protocol.md
• Errors are typed: every rejection is a BridgeError with a closed code enum.

Apps created with mini create (@openmini/cli) come wired already. For tests or custom bindings, createMiniRuntime({ transport }) builds an instance over any message channel.
