How can I create a customized version of an existing pdf file with node.js?
I have an old system that was written in PHP a long time ago that I would like to update to node.js to allow me to share code with a more modern system. Unfortunately, one of the main features of the PHP system is a tool that allows it to load an existing PDF file (which happens to be a government form), fill out the user's information, and provide a PDF to the browser that has all of that information present.
I have considered making a PHP script that will just do the PDF customization and using node for everything else, but it seems like something like this should be able to be done without requiring PHP to be installed.
Any idea how I might solve my problem just using node?

After a lot of searching and nearly giving up, I did eventually find that the HummusJS library will do what I want to do!
Update April 2020: In the intervening years since I posted this other options have cropped up which look like they should work. Since this question still gets a lot of attention I thought I'd come back and update with some other options:
- https://www.npmjs.com/package/pdf-lib - This one is my current favorite; it works great.
- https://www.npmjs.com/package/nopodofo - This one should be one of the best options out there, but I couldn't get it working myself on a mac
- https://www.npmjs.com/package/node-pdfsign - Not exactly the same thing but can be used with other tools to do digital signatures on a PDF. Haven't used it yet, but I expect do
