PDF Filler 2 (Node.js) Forked from pdffillerjs/pdffiller Currently in development!

A node.js PDF form field data filler and FDF generator toolkit. This essentially is a wrapper around the PDF Toolkit library PDF ToolKit.

Quick start

First, run npm install pdffiller --save for your app.

Import the module using:

var pdfFiller = require('pdffiller');

// ...

Examples

1.Fill PDF with existing FDF Data

var pdfFiller = require('pdffiller');

var sourcePDF = 'test/test.pdf';
var destinationPDF = 'test/test_complete.pdf';
var data = {
  last_name: 'John',
  first_name: 'Doe',
  date: 'Jan 1, 2013',
  football: 'Off',
  baseball: 'Yes',
  basketball: 'Off',
  hockey: 'Yes',
  nascar: 'Off'
};

pdfFiller.fillForm(sourcePDF, destinationPDF, data, function(err) {
  if (err) throw err;
  console.log("In callback (we're done).");
});

This will take the test.pdf, fill the fields with the data values and create a complete filled in PDF (test_filled_in.pdf). Note that the resulting PDF will be read-only.

Alternatively,

var shouldFlatten = false;

pdfFiller.fillFormWithFlatten(
  sourcePDF,
  destinationPDF,
  data,
  shouldFlatten,
  function(err) {
    if (err) throw err;
    console.log("In callback (we're done).");
  }
);

Calling fillFormWithFlatten() with shouldFlatten = false will leave any unmapped fields still editable, as per the pdftk command specification.

2. Generate FDF Template from PDF

var pdfFiller = require('pdffiller');

var sourcePDF = 'test/test.pdf';

// Override the default field name regex. Default: /FieldName: ([^\n]*)/
var nameRegex = null;

var FDF_data = pdfFiller.generateFDFTemplate(sourcePDF, nameRegex, function(
  err,
  fdfData
) {
  if (err) throw err;
  console.log(fdfData);
});

This will print out this

{
    "last_name" : "",
    "first_name" : "",
    "date" : "",
    "football" : "",
    "baseball" : "",
    "basketball" : "",
    "hockey" : "",
    "nascar" : ""
};

3. Map form fields to PDF fields

var pdfFiller = require('pdffiller');

var convMap = {
  lastName: 'last_name',
  firstName: 'first_name',
  Date: 'date',
  footballField: 'football',
  baseballField: 'baseball',
  bballField: 'basketball',
  hockeyField: 'hockey',
  nascarField: 'nascar'
};

var fieldJson = [
  {
    title: 'lastName',
    fieldfieldType: 'Text',
    fieldValue: 'John'
  },
  {
    title: 'firstName',
    fieldfieldType: 'Text',
    fieldValue: 'Doe'
  },
  {
    title: 'Date',
    fieldType: 'Text',
    fieldValue: 'Jan 1, 2013'
  },
  {
    title: 'footballField',
    fieldType: 'Button',
    fieldValue: false
  },
  {
    title: 'baseballField',
    fieldType: 'Button',
    fieldValue: true
  },
  {
    title: 'bballField',
    fieldType: 'Button',
    fieldValue: false
  },
  {
    title: 'hockeyField',
    fieldType: 'Button',
    fieldValue: true
  },
  {
    title: 'nascarField',
    fieldType: 'Button',
    fieldValue: false
  }
];

var mappedFields = pdfFiller.mapForm2PDF(fieldJson, convMap);
console.log(mappedFields);

This will print out the object below.

{
    "last_name" : "John",
    "first_name" : "Doe",
    "date" : "Jan 1, 2013",
    "football" : "Off",
    "baseball" : "Yes",
    "basketball" : "Off",
    "hockey" : "Yes",
    "nascar" : "Off"
};

4. Convert fieldJson to FDF data

var pdfFiller   = require('pdffiller');

var fieldJson = [
    {
        "title" : "last_name",
        "fieldfieldType": "Text",
        "fieldValue": "Doe"
    },
    {
        "title" : "first_name",
        "fieldfieldType": "Text",
        "fieldValue": "John"
    },
    {
        "title" : "date",
        "fieldType": "Text",
        "fieldValue": "Jan 1, 2013"
    },
    {
        "title" : "football",
        "fieldType": "Button",
        "fieldValue": false
    },
    {
        "title" : "baseball",
        "fieldType": "Button",
        "fieldValue": true
    },
    {
        "title" : "basketball",
        "fieldType": "Button"
        "fieldValue": false
    },
    {
        "title" : "hockey",
        "fieldType": "Button"
        "fieldValue": true
    },
    {
        "title" : "nascar",
        "fieldType": "Button"
        "fieldValue": false
    }
];

var FDFData = pdfFiller.convFieldJson2FDF( fieldJson );
console.log(FDFData)

This will print out this

{
    "last_name" : "John",
    "first_name" : "Doe",
    "date" : "Jan 1, 2013",
    "football" : "Off",
    "baseball" : "Yes",
    "basketball" : "Off",
    "hockey" : "Yes",
    "nascar" : "Off"
};
