fill-pdf

A node module to fill out PDF forms (utf8 compatible).

It uses pdftk to fill out PDF forms.

Installation

npm install fill-pdf

Dependencies

You need to have the pdftk binary in your PATH.

Install on Mac OSX

• To install PDFtk use the official installer or if you have homebrew-cask installed you can run brew cask install pdftk

Install on Ubuntu

sudo apt-get install pdftk

Usage example (with express)

const fillPdf = require("fill-pdf");
const formData = { FieldName: 'Text to put into form field' };
const pdfTemplatePath = "templates.pdf";

app.get('/filled_form.pdf', (req, res) => {
  fillPdf.generatePdf(formData, pdfTemplatePath, function(err, output) {
    if ( !err ) {
      res.type("application/pdf");
      res.send(output);
    }
  });
});

Passing Custom Arguments to pdftk

For more specific uses, you can also pass some extra arguments to pdftk. It is done by specifying them as an array, given as a third argument of the fillPdf function.

For instance, if you want to make the output PDF not editable anymore, you can append the flatten argument such as:

const fillPdf = require('fill-pdf');

const extraArgs = ['flatten'];
fillPdf.generatePdf(formData, pdfTemplatePath, extraArgs, (err, output) => {
  // ...
});

Take a look on man pdftk to get a list of all available arguments.
