isjpeg
1.0.1 • Public • Published 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
