推荐一个极其简单、及其好用的node.js的压缩和解压缩类库 compressing
支持格式： tar、gzip、tgz、zip
以zip为例，tar，tgz和gzip与zip相同。
压缩文件：
const compressing = require('compressing');
compressing.zip.compressFile('logs/info-2018-06-07.log', 'logs/test.zip').then(() => {}).catch(() => {});
//或者
await compressing.zip.compressFile('logs/info-2018-06-07.log', 'logs/test.zip')
压缩文件夹：
const compressing = require('compressing');
compressing.zip.compressDir('logs', 'test3.zip').then(()=>{}).catch(()=>{});
//或者
await compressing.zip.compressDir('logs', 'test3.zip')
使用Stream压缩多个文件（非常强大）
const fs=require('fs');
const compressing = require('compressing');
const zipStream = new compressing.zip.Stream();
zipStream.addEntry('./logs/error-2018-06-07.log')
zipStream.addEntry('./logs/info-2018-06-07.log')
const destStream = fs.createWriteStream('test4.zip');
const pipe = require('multipipe');
pipe(zipStream, destStream, (err) => {
console.log(err);
})
Stream可以是dir、file、buffer、stream
// dir zipStream.addEntry('dir/path/to/compress'); // file zipStream.addEntry('file/path/to/compress'); // buffer zipStream.addEntry(buffer); // stream zipStream.addEntry(stream);
解压缩：
const compressing = require('compressing');
compressing.zip.uncompress('test3.zip', 'test3').then(() => {}).catch(() => {});
//或者
await compressing.zip.uncompress('test3.zip', 'test3') //如果要解压到当前目录换成 './'
