Find the type of the file/folder passed to the CLI in nodejs

I'm creating a CLI app and using commander to process the commands entered by the user.

program
.option('-i , --index', 'file ') // option for adding a file/folder
const options = program.opts();
if(option.index){ // do sth }

And the user can enter node index.js --index "Silver Blaze".txt or pass a folder node index.js --index "my folder"

How do I find out the type of the value passed (if it is a file or folder)?

node-commander node.js javascript

You can use the fs module for that.

Example

let fs = require('fs')
let stats = fs.statSync(/* Path to file/folder */)

let isFile = stats.isFile()
let isDir = stats.isDirectory()

if (isFile) {
  // File
} else if (isDir) {
  // Directory
}
