pump
1.1、pump简介
是什么 ?:a small node module that pipes streams together and destroys all of them if one of them closes.
开发语言:Node.js
源码仓库:https://github.com/mafintosh/pump
1.2、通过包管理器安装pump
包管理器安装命令
npmnpm install pump --save
yarnyarn add pump
1.3、pump API
Stream stream = pump(streams: Array, callback?: function(error));
Stream stream = pump(...streams: Array, callback?: function(error));

使用示例：

const pump = require('pump');
const fs   = require('fs');
const zlib = require('zlib');

pump(
    fs.createReadStream('archive.tar'),
    zlib.createGzip(),
    fs.createWriteStream('archive.tar.gz'),
    (err) => {
        if (err) {
            console.error('Pipeline failed.', err);
        } else {
            console.log('Pipeline succeeded.');
        }
    }
);

注意：Node.js Runtime 10增加了stream.pipeline方法，用来代替该模块。

const { pipeline } = require('stream');
const fs   = require('fs');
const zlib = require('zlib');

pipeline(
    fs.createReadStream('archive.tar'),
    zlib.createGzip(),
    fs.createWriteStream('archive.tar.gz'),
    (err) => {
        if (err) {
            console.error('Pipeline failed.', err);
        } else {
            console.log('Pipeline succeeded.');
        }
    }
);
