stream 流

源代码: lib/stream.js

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

Node.js 提供了许多流对象。 例如，对 HTTP 服务器的请求和 process.stdout 都是流的实例。

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。

要访问 stream 模块：

const stream = require('stream');

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

Source Code: lib/stream.js

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

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

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

To access the stream module:

const stream = require('stream');

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