pdffiller-aws-lambda

PDF Filler (Node.js)
======

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-aws-lambda --save for your app.

Import the module using:

``js
var pdfFiller = require('pdffiller');

// ...
`

Examples

#### 1.Fill PDF with existing FDF Data
``javascript
var pdfFiller = require('pdffiller-aws-lambda');

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,

``javascript

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
``javascript
var pdfFiller = require('pdffiller-aws-lambda');

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
``javascript
var pdfFiller = require('pdffiller-aws-lambda');

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
``javascript
var pdfFiller = require('pdffiller-aws-lambda');

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"
};
```
