是否可以用 node 的 stream 来读并改写最后写入到同一个文件？

[dxcqcv]

我现在的做法是多创建一个临时文件，然后删除原文件，重命名临时文件，我想知道有没有更好的办法来实现用 node 流来改写同文件？

代码如下

const rm = require('rimraf')
const through2 = require('through2')
const fs = require('graceful-fs')
// source file path
const replacementPath = `./static/projects/${destPath}/index.html`
// temp file path
const tempfilePath = `./static/projects/${destPath}/tempfile.html`
// read source file then write into temp file
await promiseReplace(replacementPath, tempfilePath)    
// del the source file
rm.sync(replacementPath)
// rename the temp file name to source file name
fs.renameSync(tempfilePath, replacementPath)
// del the temp file
rm.sync(tempfilePath)

// promiseify readStream and writeStream
function promiseReplace (readfile, writefile) {
  return new Promise((res, rej) => {
    fs.createReadStream(readfile)
      .pipe(through2.obj(function (chunk, encoding, done) {
        const replaced = chunk.toString().replace(/id="wrap"/g, 'dududud')
        done(null, replaced)
      }))
      .pipe(fs.createWriteStream(writefile))
      .on('finish', () => {
        console.log('replace done')
        res()
      })
      .on('error', (err) => {
        console.log(err)
        rej(err)
      })
  })
}

应该是不行的 要么全读进内存 要么创建临时文件
