isjpeg

is that file really (probably) a jpeg‽

Check the first 2 bytes of the file header to see if it's a JPEG

For when you just don't trust file extensions anymore.

Usage

module

npm install isjpeg

var isJpeg = require('isjpeg')
 
isJpeg('/path/to/mysterious/file', function (err, jpeg) {
  if (err) throw err
  if (jpeg) {
    console.log('file is totes JPEG.')
  } else {
    console.log('ceci n\'est pas une JPEG.')  
  }
})

command line

npm install -g isjpeg

isjpeg ~/Pictures/
/Users/oli/Pictures/MagrittePipe.jpg is JPEG
