存储运行时引用
Section titled “存储运行时引用”使用 createPluginRuntimeStore 存储运行时引用,以便在 register 回调之外使用:
import { createPluginRuntimeStore } from "openclaw/plugin-sdk/runtime-store";import type { PluginRuntime } from "openclaw/plugin-sdk/runtime-store";
const store = createPluginRuntimeStore<PluginRuntime>("my-plugin runtime not initialized");
// In your entry pointexport default defineChannelPluginEntry({ id: "my-plugin", name: "My Plugin", description: "Example", plugin: myPlugin, setRuntime: store.setRuntime,});
// In other filesexport function getRuntime() { return store.getRuntime(); // throws if not initialized}
export function tryGetRuntime() { return store.tryGetRuntime(); // returns null if not initialized}其他顶层 api 字段
Section titled “其他顶层 api 字段”除了 api.runtime,API 对象还提供:
| 字段 | 类型 | 描述 |
