研究 node lzma 的压缩解压缩

/* eslint-disable */

// // 压缩为 lzma
// var fs = require(‘fs‘);
// var lzma = require(‘lzma-native‘);
// var compressor = lzma.createCompressor();
// var input = fs.createReadStream(‘README.md‘);
// var output = fs.createWriteStream(‘README.md.lzma‘);
// input.pipe(compressor).pipe(output);

// // 解压 lzma
// var fs = require(‘fs‘);
// var lzma = require(‘lzma-native‘);
// var compressor = lzma.createDecompressor();
// var input = fs.createReadStream(‘README.md.lzma‘);
// var output = fs.createWriteStream(‘README2.md‘);
// input.pipe(compressor).pipe(output);


// // 压缩为 lzma
// // https://github.com/nickdesaulniers/lzma-stream
// var fs = require(‘fs‘);
// var lzma = require(‘lzma-stream‘); // 下载仓库作为 lzma-stream require

// var compressor = new lzma.LZMACompressionStream;
// var decompressor = new lzma.LZMADecompressionStream;
// var output = fs.createWriteStream(‘a.lzma‘);
// fs.createReadStream(‘./a.txt‘)
//   .pipe(compressor)
//   .pipe(output);
