How to delete all files in nodejs

Node.js is a JavaScript runtime environment based on the Chrome V8 engine that uses an event-driven, non-blocking I/O model, making it ideal for building high-performance, scalable web applications. In Node.js, sometimes you need to delete all files in a certain directory. Let’s introduce the method of deleting all files in Node.js.

In Node.js, deleting all files in the directory can be completed through the following steps:

1. Introduce the fs module

Node.js provides the fs module, this The module provides an API for file reading and writing operations. We can use it to handle file-related operations. First, we need to introduce the fs module. The code is as follows:

const fs = require('fs');

2. Define the delete file function

Define a recursive function to delete all files under the specified path. The specific implementation is as follows:

function deleteAllFiles(path) {
  let files = [];
  if( fs.existsSync(path) ) {
    files = fs.readdirSync(path);
    files.forEach(function(file,index){
      let curPath = path + "/" + file;
      if(fs.statSync(curPath).isDirectory()) { // recurse
        deleteAllFiles(curPath);
      } else { // delete file
        fs.unlinkSync(curPath);
      }
    });
    fs.rmdirSync(path);
  }
}

3. Call the delete file function

Call the function just defined and pass in the directory path. Start deleting all files, the code is as follows:

deleteAllFiles('path/to/dir');

The complete code is as follows:

const fs = require('fs');

function deleteAllFiles(path) {
  let files = [];
  if( fs.existsSync(path) ) {
    files = fs.readdirSync(path);
    files.forEach(function(file,index){
      let curPath = path + "/" + file;
      if(fs.statSync(curPath).isDirectory()) { // recurse
        deleteAllFiles(curPath);
      } else { // delete file
        fs.unlinkSync(curPath);
      }
    });
    fs.rmdirSync(path);
  }
}

deleteAllFiles('path/to/dir');

As you can see, it is not complicated to use Node.js to delete all files in the specified directory. You only need to introduce the fs module , define a recursive function and then call it.
