expressjsHow do I delete a file using Express.js?

To delete a file using Express.js, you can use the fs.unlink() method. This method takes the path of the file to be deleted as its argument. The code below shows an example of how to use it:

// Import the filesystem module
const fs = require('fs');

// Path of the file to be deleted
const filePath = '/path/to/file.txt';

// Delete the file
fs.unlink(filePath, (err) => {
  if (err) throw err;
  console.log(`${filePath} was deleted`);
});

Output example

/path/to/file.txt was deleted

The code above consists of the following parts:

1. const fs = require('fs') imports the filesystem module.
2. const filePath = '/path/to/file.txt' specifies the path of the file to be deleted.
3. fs.unlink(filePath, (err) => {...}) calls the fs.unlink() method, which takes the path of the file to be deleted as its argument.
4. if (err) throw err checks if an error occurred and throws it if it did.
5. console.log(${filePath} was deleted) logs a message to the console indicating that the file was deleted.
