`dirname` 和 `filename` Jump to heading

__dirname 和 __filename 是 CommonJS 全局变量。它们在 npm 包作用域内的 CommonJS 模块中可用，但在 ES 模块中未定义。在您自己的 ES 模块中，请改用 import.meta.dirname 和 import.meta.filename，它们为当前模块提供相同的值。

模块说明 Jump to heading

node:worker_threads Jump to heading

Deno 2.7 显著提升了 node:worker_threads 的兼容性：

stdout 和 stderr 流会从 worker 正确转发到父进程。
worker.terminate() 现在会以正确的退出码解析。
支持 workerData、execArgv 和 threadName 选项。
已实现 worker.performance.eventLoopUtilization() 和 worker.cpuUsage()。
来自 worker 线程的 BroadcastChannel 能正确进行 ref/unref。

node:child_process Jump to heading

Deno 2.7 提升了 node:child_process 的兼容性：

stdio 流（stdin、stdout、stderr）会作为 Socket 实例暴露，与 Node.js 行为一致。
Shell 重定向（>、<、>>）可在 exec() 和 execSync() 中正常工作。
fork() 接受 URL 作为模块路径。
timeout 和 killSignal 选项在 exec() 和 spawn() 中受到支持。
NODE_OPTIONS 环境变量会被 fork() 的子进程遵循。

node:zlib Jump to heading

Deno 2.7 为 node:zlib 添加了 Zstd 压缩支持：

import zlib from "node:zlib";
import { promisify } from "node:util";

const compress = promisify(zlib.zstdCompress);
const decompress = promisify(zlib.zstdDecompress);

const compressed = await compress(Buffer.from("你好，Deno！"));
const result = await decompress(compressed);
console.log(result.toString()); // "你好，Deno！"

同步版本 zlib.zstdCompressSync() 和 zlib.zstdDecompressSync() 也可用。

node:sqlite Jump to heading

Deno 2.7 为 node:sqlite 添加了多个新 API：

DatabaseSync.setAuthorizer(callback) — 注册一个回调，该回调会在每次 SQL 操作时被调用，从而能够对允许哪些表和操作进行细粒度访问控制：

import { constants, DatabaseSync } from "node:sqlite";

const db = new DatabaseSync(":memory:");
db.exec("CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT)");

// 允许读取，拒绝其他所有操作
db.setAuthorizer((_action, _table) => {
  return constants.SQLITE_OK;
});

DatabaseSync.enableDefensive(enabled) — 启用或禁用防御模式，该模式可阻止某些潜在危险的数据库操作，例如在运行时修改 schema。
DatabaseSync.createTagStore() — 创建一个预处理语句缓存，将 SQL 字符串映射到已编译语句，以便高效重复执行。
