压缩：

从index.html压缩成index.html.gz

const zlib = require('zlib');

const gzip = zlib.createGzip();
const fs = require('fs');
const inp = fs.createReadStream('index.html');
const out = fs.createWriteStream('index.html.gz');

inp.pipe(gzip)
  .on('error', () => {
    // 处理错误
  })
  .pipe(out)
  .on('error', () => {
    // 处理错误
  });

解压：

从index.html.gz解压为index.html

const zlib = require('zlib');

const gzip = zlib.createGzip();
const fs = require('fs');
const inp = fs.createReadStream('index.html.gz');
const out = fs.createWriteStream('index.html');

inp.pipe(gzip)
  .on('error', () => {
    // 处理错误
  })
  .pipe(out)
  .on('error', () => {
    // 处理错误
  });
