3-04zilib-文件打包并压缩

const zlib = require( 'zlib' )
const fs = require( 'fs' )
const inp = fs.createReadStream('./dist/1.txt')
const out = fs.createWriteStream('1.txt.gz')
const gzlib = zlib.createGzlip()
inp 
    .pipe( gzlib )
    .pipe( out )

• zlib是一个压缩包的内置模块

• fs是文件系统

• const inp = fs.createReadStream('路径') // 创建可读的流

• const out = fs.createWriteStream('路径') //创建可写的流

• const gzlib = zlib.createGzlip() // 创建一个空的压缩包
