Node.js/TypeScript SDK

@speedle/sdk 0.1.0 发布后用 npm 安装，再向本地 Speedle 或 Speedle Cloud 调用 isAllowed 与 check。

Node.js SDK 需要 Node.js 22 或更高版本，同时提供 ESM 和 CommonJS 构建及 TypeScript 类型，没有运行时依赖。软件包：npm 上的 @speedle/sdk 0.1.0，发布后可用。参考文档：speedle-sdk/node。

示例检查的策略见 SDK。

添加依赖

新建 ES 模块包并安装（发布后可用）：

mkdir speedle-example
cd speedle-example
npm init -y
npm pkg set type=module
npm install @speedle/sdk@0.1.0

调用本地 Speedle

按 SDK 一节启动 Speedle 并创建示例策略。将以下程序保存为 main.ts：

import { Auth, Reason, SpeedleClient, SpeedleError } from "@speedle/sdk";

try {
  const speedle = new SpeedleClient({
    backend: "speedle-plus",
    endpoint: "http://localhost:6734",
    auth: Auth.none(),
    serviceName: "docs",
  });
  try {
    const allowed = await speedle.isAllowed("alice", "get", "/docs/public");
    console.log(`alice get /docs/public: allowed=${allowed}`);

    const d = await speedle.check("alice", "delete", "/docs/public");
    console.log(`alice delete /docs/public: allowed=${d.allowed} reason=${Reason[d.reason] ?? d.reason}`);
  } finally {
    await speedle.close();
  }
} catch (e) {
  if (!(e instanceof SpeedleError)) throw e;
  console.error(`Speedle error: ${e.message}`);
  process.exitCode = 1;
}

运行。Node.js 22.18 或更高版本可以直接运行 TypeScript 文件：

node main.ts

输出：

alice get /docs/public: allowed=true
alice delete /docs/public: allowed=false reason=NoApplicablePolicies

调用 Speedle Cloud

Speedle Cloud 即将上线。

程序从 SPEEDLE_SERVICE 读取服务名，从 SPEEDLE_TOKEN 读取该服务的令牌。SPEEDLE_ENDPOINT 可覆盖默认端点 https://cloud.speedle.io。将 main.ts 替换为：

import { Auth, Reason, SpeedleClient, SpeedleError } from "@speedle/sdk";

try {
  const speedle = new SpeedleClient({
    backend: "speedle-cloud",
    endpoint: process.env.SPEEDLE_ENDPOINT ?? "https://cloud.speedle.io",
    auth: Auth.bearer(process.env.SPEEDLE_TOKEN ?? ""),
    serviceName: process.env.SPEEDLE_SERVICE ?? "",
  });
  try {
    const allowed = await speedle.isAllowed("alice", "get", "/docs/public");
    console.log(`alice get /docs/public: allowed=${allowed}`);

    const d = await speedle.check("alice", "delete", "/docs/public");
    console.log(`alice delete /docs/public: allowed=${d.allowed} reason=${Reason[d.reason] ?? d.reason}`);
  } finally {
    await speedle.close();
  }
} catch (e) {
  if (!(e instanceof SpeedleError)) throw e;
  console.error(`Speedle error: ${e.message}`);
  process.exitCode = 1;
}

设置环境变量后运行。read -rs 不会把令牌写入 shell 历史，也不会显示在屏幕上：

export SPEEDLE_SERVICE=docs
read -rs SPEEDLE_TOKEN && export SPEEDLE_TOKEN
node main.ts

服务中已有示例策略时，输出为：

alice get /docs/public: allowed=true
alice delete /docs/public: allowed=false reason=NoApplicablePolicies

令牌是服务端密钥，切勿放进浏览器、移动应用或桌面客户端。
