* [用法示例](https://nodejs.org/dist/latest-v14.x/docs/api/synopsis.html) * * * * [Assertion testing](https://nodejs.org/dist/latest-v14.x/docs/api/assert.html)：該`assert`模塊提供了一組用于驗證不變量的斷言函數。用來測試是否滿足條件的，如果不滿足就執行中斷。斷言是一個包含布爾表達式的語句，在執行這個語句時假定該表達式為 true。如果表達式計算為 false，那么系統會報告一個 Assertionerror * * [Async hooks](https://nodejs.org/dist/latest-v14.x/docs/api/async_hooks.html)：該`async_hooks`模塊提供了一個用于跟蹤異步資源的API。可以使用以下命令訪問它： ~~~js const async_hooks = require('async_hooks'); ~~~ * * [Buffer](https://nodejs.org/dist/latest-v14.x/docs/api/buffer.html)：`Buffer`對象用于表示固定長度的字節序列。許多Node.js API支持`Buffer`。該`Buffer`班是JavaScript的一個子[`Uint8Array`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array)類，并覆蓋更多的用例方法進行了擴展。[`Uint8Array`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array)只要`Buffer`支持，Node.js API都接受plain。 * * [C++ addons](https://nodejs.org/dist/latest-v14.x/docs/api/addons.html)：用C ++編寫的動態鏈接的共享對象。該[`require()`](https://nodejs.org/dist/latest-v14.x/docs/api/modules.html#modules_require_id)函數可以將加載項作為普通的Node.js模塊加載。插件提供JavaScript和C / C ++庫之間的接口 * * [C/C++ addons with N-API](https://nodejs.org/dist/latest-v14.x/docs/api/n-api.html)：是用于構建本機插件的API。它獨立于底層JavaScript運行時（例如V8），并作為Node.js本身的一部分進行維護 * * [C++ embedder API](https://nodejs.org/dist/latest-v14.x/docs/api/embedding.html)：Node.js提供了許多C ++ API，這些API可用于在Node.js環境中通過其他C ++軟件執行JavaScript * * [Child processes](https://nodejs.org/dist/latest-v14.x/docs/api/child_process.html) * [Cluster](https://nodejs.org/dist/latest-v14.x/docs/api/cluster.html) * [Command line options](https://nodejs.org/dist/latest-v14.x/docs/api/cli.html) * [Console](https://nodejs.org/dist/latest-v14.x/docs/api/console.html) * [Crypto](https://nodejs.org/dist/latest-v14.x/docs/api/crypto.html) * [Debugger](https://nodejs.org/dist/latest-v14.x/docs/api/debugger.html) * [Deprecated APIs](https://nodejs.org/dist/latest-v14.x/docs/api/deprecations.html) * [DNS](https://nodejs.org/dist/latest-v14.x/docs/api/dns.html) * [Domain](https://nodejs.org/dist/latest-v14.x/docs/api/domain.html) * [Errors](https://nodejs.org/dist/latest-v14.x/docs/api/errors.html) * [Events](https://nodejs.org/dist/latest-v14.x/docs/api/events.html) * [File system](https://nodejs.org/dist/latest-v14.x/docs/api/fs.html) * [Globals](https://nodejs.org/dist/latest-v14.x/docs/api/globals.html) * [HTTP](https://nodejs.org/dist/latest-v14.x/docs/api/http.html) * [HTTP/2](https://nodejs.org/dist/latest-v14.x/docs/api/http2.html) * [HTTPS](https://nodejs.org/dist/latest-v14.x/docs/api/https.html) * [Inspector](https://nodejs.org/dist/latest-v14.x/docs/api/inspector.html) * [Internationalization](https://nodejs.org/dist/latest-v14.x/docs/api/intl.html) * [Modules: CommonJS modules](https://nodejs.org/dist/latest-v14.x/docs/api/modules.html) * [Modules: ECMAScript modules](https://nodejs.org/dist/latest-v14.x/docs/api/esm.html) * [Modules:`module`API](https://nodejs.org/dist/latest-v14.x/docs/api/module.html) * [Net](https://nodejs.org/dist/latest-v14.x/docs/api/net.html) * [OS](https://nodejs.org/dist/latest-v14.x/docs/api/os.html) * [Path](https://nodejs.org/dist/latest-v14.x/docs/api/path.html) * [Performance hooks](https://nodejs.org/dist/latest-v14.x/docs/api/perf_hooks.html) * [Policies](https://nodejs.org/dist/latest-v14.x/docs/api/policy.html) * [Process](https://nodejs.org/dist/latest-v14.x/docs/api/process.html) * [Punycode](https://nodejs.org/dist/latest-v14.x/docs/api/punycode.html) * [Query strings](https://nodejs.org/dist/latest-v14.x/docs/api/querystring.html) * [Readline](https://nodejs.org/dist/latest-v14.x/docs/api/readline.html) * [REPL](https://nodejs.org/dist/latest-v14.x/docs/api/repl.html) * [Report](https://nodejs.org/dist/latest-v14.x/docs/api/report.html) * [Stream](https://nodejs.org/dist/latest-v14.x/docs/api/stream.html) * [String decoder](https://nodejs.org/dist/latest-v14.x/docs/api/string_decoder.html) * [Timers](https://nodejs.org/dist/latest-v14.x/docs/api/timers.html) * [TLS/SSL](https://nodejs.org/dist/latest-v14.x/docs/api/tls.html) * [Trace events](https://nodejs.org/dist/latest-v14.x/docs/api/tracing.html) * [TTY](https://nodejs.org/dist/latest-v14.x/docs/api/tty.html) * [UDP/datagram](https://nodejs.org/dist/latest-v14.x/docs/api/dgram.html) * [URL](https://nodejs.org/dist/latest-v14.x/docs/api/url.html) * [Utilities](https://nodejs.org/dist/latest-v14.x/docs/api/util.html) * [V8](https://nodejs.org/dist/latest-v14.x/docs/api/v8.html) * [VM](https://nodejs.org/dist/latest-v14.x/docs/api/vm.html) * [WASI](https://nodejs.org/dist/latest-v14.x/docs/api/wasi.html) * [Worker threads](https://nodejs.org/dist/latest-v14.x/docs/api/worker_threads.html) * [Zlib](https://nodejs.org/dist/latest-v14.x/docs/api/zlib.html)
