@timetotrade/pdfform.js v0.0.1

@timetotrade/pdfform.js

This code only works on browsers NOT node servers

as the node implementation relied on libraries that broke broswer functionality

Fill out PDF forms in pure JavaScript, both in the browser or on the server.

pdfform.js can function with a slightly customized version of pdf.js. However, due to the size and scope of PDF.js (1600KB+), by default a built-in PDF library (called minipdf) is used.

The online demo demonstrates both (not recommended in actual production).

Installation

To use in a browser, download and serve either pdfform.minipdf.dist.js (minipdf, recommended) or pdfform.pdf_js.dist.js (pdf.js).

Alternatively, download/clone this repository and add minipdf.js and pdfform.js to your JavaScript files. You'll also need the pako library.

Usage

Simply call transform with the PDF file contents and the fields.

<!-- download from https://raw.githubusercontent.com/phihag/pdfform.js/dist/dist/pdfform.minipdf.dist.js -->
<script src="downloaded/pdfform.minipdf.dist.js"></script>
<script>
var pdf_buf = ...; // load PDF into an ArrayBuffer, for example via XHR (see demo)
var fields = {
    'fieldname': ['value for fieldname[0]', 'value for fieldname[1]'],
};
var out_buf = pdfform().transform(pdf_buf, fields);
// Do something with the resulting PDF file in out_buf
</script>

There is also a list_fields function which allows you to list all available fields and their types.

For more details, have a look at the demo and its JavaScript code.
