流

¥Stream

源代码: lib/stream.js

流是用于在 Node.js 中处理流数据的抽象接口。node:stream 模块提供了用于实现流接口的 API。

¥A stream is an abstract interface for working with streaming data in Node.js. The node:stream module provides an API for implementing the stream interface.

Node.js 提供了许多流对象。例如，向 HTTP 服务器请求 和 process.stdout 都是流实例。

¥There are many stream objects provided by Node.js. For instance, a request to an HTTP server and process.stdout are both stream instances.

流可以是可读的、可写的、或两者兼而有之。所有的流都是 EventEmitter 的实例。

¥Streams can be readable, writable, or both. All streams are instances of EventEmitter.

要访问 node:stream 模块：

¥To access the node:stream module:

const stream = require('node:stream'); 拷贝

node:stream 模块对于创建新类型的流实例很有用。通常不需要使用 node:stream 模块来消费流。

¥The node:stream module is useful for creating new types of stream instances. It is usually not necessary to use the node:stream module to consume streams.
