IDGlobal teaches you how to create folders in node.js

Generally, for the copy operation of small files, the pipeline transportation operation of stream is used,

First you need to load the imported files:

var fs = require('fs');

1. Create folders synchronously

fs.mkdirSync(yourfileDirPath);

Create folder asynchronously

fs.mkdir(yourfileDirPath);

2. Determine whether the folder exists—synchronization

fs.existsSync(dirpath);

Asynchronous

fs. exists(dirpath);

Using the above related operations, we can directly write a method to determine the creation of a folder,

 
function mkdir(dirpath,dirname) {
  //Determine that the second parameter can not be passed in
  //Judge whether the second parameter is normal, avoid passing in wrong parameters when calling
  if (dirname !== path.dirname(dirpath)) {
   mkdir(dirpath);
   return;
  }
  if (fs. existsSync(dirname)) {
   fs.mkdirSync(dirpath)
  } else {
   mkdir(dirname, path.dirname(dirname));
   fs.mkdirSync(dirpath);
  }
}
 

Pay attention to synchronous and asynchronous creation, reading and other issues, otherwise the folder does not exist when copying, it is recommended to use the synchronous creation Sync method, generally in the form of fs.xxxSync

The above is all the content about the method of creating folders in node.js. After understanding, I believe everyone can find out the problem. If you want to know more about technology, please pay attention to INTERNET DATA.
