pdfmerger

pdfmerger

pdfmerger combines multiple PDF-files into a single PDF-file. It is a node module that utilizes the Apache PDFBox Library, which the required functionality are distributed along with this module. The only requirement for this module to run, is having Java 6 or higher in the path.

This package is inspired from karuppiah's easy-pdf-merge, but instead of using a callback approach, this module returns a stream interface.

Usage:

The module can merge a provided list of PDFs, or merge all PDFs present in a directory of your choice, in alphanumeric order. You can set a file path, which will write the file to that location, or just handle the stream yourselves.

var pdfmerger = require('pdfmerger');

// Combining pdfs by using file paths

var pdfs = [
  '/path/to/pdf1.pdf',
  '/path/to/pdf2.pdf'
];

var pdfStream = pdfmerger(pdfs);

var writeStream = fs.createWriteStream('path/to/combined.pdf');
pdfStream.pipe(writeStream);

// write the output to a file

pdfmerger(pdfs, '/path/to/combined.pdf');

// combine all pdfs in a directory

pdfmerger('/path/to/directory', '/path/to/combined.pdf');

// Stream events

pdfStream.on('data', function(data) {

});

pdfStream.on('error', function(error) {

});

pdfStream.on('close', function(code) {

});
