API

isPDF(path, cb)

This is asynchronous API for checking if file is PDF. This API takes two parameters:

1. File path which needs to be checked and
2. callback, which is invoked when it checks the file to be PDF or not or in case of errors

It throws

1. TypeError if path is not provided or if provided but not of type String or if callback is not provided or if provided but not of type Function
2. FileNotExists error which specified file does not exists.

Callback has two parameters:

1. First parameter is error which is null in case of success
2. Second parameter is boolean value which indicates if file is PDF or not

Example

var PDF_FILE = require('is-pdf-file');

// If a valid pdf file is provided and exists at path specified
PDF_FILE.isPDF('temp.pdf', function(err, is) {
    if(err) {
        console.log('Error while checking if file is PDF : ' + err);
    } else {
        console.log('Given file is PDF : ' + is);
    }
});
