How to delete a file in Node.js

In Node.js, you can use the fs.unlink() method provided by the built-in fs module to delete a file from the local file system.

Here is an example that demonstrates how you can use this method:

const fs = require('fs')

// delete a file
fs.unlink('file.txt', err => {
  if (err) {
    throw err
  }

  console.log('File is deleted.')
})

The fs.unlink() method works asynchronously and doesn't block the Node.js event loop while deleting a file.

The fs module also provides a synchronous method called fs.unlinkSync() to delete a file synchronously, like below:

const fs = require('fs')

// delete a file
try {
  fs.unlinkSync('file.txt')

  console.log('File is deleted.')
} catch (error) {
  console.log(error)
}

Be careful while using synchronous methods from the fs module. These methods block the Node.js event loop until the file operation is completed. It may affect performance when you are performing a lot of concurrent tasks.
