Fork of istex popplonode for recent node version

Popplonode

Return metadata & text extraction of a PDF file

Why Popplonode

Popplonode is an addons node.js which means it use pure c++ code, it's clearly faster than PDFJS & it's faster than a spawn of Poppler pdfinfo too! because we only use specific c++ class of it.

Install

npm install popplonode

INFO If you want to use it with a particular version of node(eg: 8.5) you will need:

sudo apt-get install cmake g++
brew install cmake

Usage

const Popplonode = require('popplonode');

const poppl = new Popplonode();

// We load the PDF file into poppl
poppl.load('path/to/my/file.pdf'); 

// We can access the metadata of the PDF file
const metadata = poppl.getMetadata(); // 

poppl.getTextFromPage(0, (error, content) => {
  // do something with the content page
});
