Copy link 

fs.createReadStream('../src/1.html').pipe(fs.createWriteStream('../dest/1.html'));
fs.createReadStream('../src/1.css').pipe(fs.createWriteStream('../dest/1.css'));
fs.createReadStream('../src/a.js').pipe(fs.createWriteStream('../dest/a.js'));

Check this out:

This is my setup:

var fs = require('fs')
fs.mkdirSync('src')
fs.mkdirSync('dest')
fs.writeFileSync('./src/1.html','<html></html>')
fs.writeFileSync('./src/1.css','body {background-color:#f00}')
fs.writeFileSync('./src/a.js','"use strict"\n\nvar a = 0;')

Then I run this:

var fs = require('fs')
fs.createReadStream('./src/1.html').pipe(fs.createWriteStream('./dest/1.html'));
fs.createReadStream('./src/1.css').pipe(fs.createWriteStream('./dest/1.css'));
fs.createReadStream('./src/a.js').pipe(fs.createWriteStream('./dest/a.js'));

and all files are copied as expected, and regarding this: jprichardson/node-fs-extra#79 , the same code works the same with fs-extra, (with the code above or with require('fs-extra').copy('./src', './dest')).

...the best thing would be to push a repo with the exact files the code you're running so that we could reproduce it. Also, include node version and the fs/fs-extra versions you're using.

该文件（1.html）内容应该在缓存中，表面上还是有内容的，但实际内容已经为空了。当我关闭编辑器重新打开后，再次运行就得到正确的结果了。
你的建议已收到。

Google translate:

The file (1.html) content should be in the cache, on the surface or with the content, but the actual content is already empty. When I close the editor re-open and run it again to get the correct result.
Your suggestion has been received.

Sounds like it's a problem with your editor, like it's not watching the file changes.
