Nodejs使用fs-extra模块进行目录和文件操作用法示例

const fs = require('fs-extra');
const dir = '/Users/tal/Library/Application Support';

fs.ensureDir(dir, function (err) {
  if (err) {
    console.error(err);
  } else {
    console.log('Directory created successfully!');
  }
});

const fs = require('fs-extra');
const file = '/Users/tal/Library/Application Support/example.txt';

fs.ensureFile(file, function (err) {
  if (err) {
    console.error(err);
  } else {
    console.log('File created successfully!');
  }
});

const fs = require('fs-extra');
const dir = '/Users/tal/Library/Application Support';

fs.emptyDir(dir, function (err) {
  if (err) {
    console.error(err);
  } else {
    console.log('Directory emptied successfully!');
  }
});

remove(dir, callback)

var fs = require('fs-extra')
 
fs.remove('/tmp/myfile', function(err) {
  if (err) return console.error(err)
 
  console.log("success!")
})
 
fs.removeSync('/home/jprichardson')
