What is jspdf?
The jsPDF npm package is a library that allows you to generate PDF documents using JavaScript. It can be used in a web browser or in a server-side environment using Node.js. It provides a wide range of features to create and manipulate PDF documents programmatically.
What are jspdf's main functionalities?
Text
This feature allows you to add text to a PDF document. The code sample demonstrates how to create a PDF with the text 'Hello world!' at coordinates (10, 10) on the page.
const { jsPDF } = require('jspdf');
const doc = new jsPDF();
doc.text('Hello world!', 10, 10);
doc.save('hello_world.pdf');
Graphics
This feature allows you to draw shapes and graphics, such as rectangles, circles, and lines. The code sample shows how to draw a filled red rectangle with a black border.
const { jsPDF } = require('jspdf');
const doc = new jsPDF();
doc.setDrawColor(0);
doc.setFillColor(255, 0, 0);
doc.rect(20, 20, 10, 10, 'FD');
doc.save('rectangle.pdf');
Images
This feature allows you to embed images into a PDF. The code sample demonstrates adding an image to the PDF, specifying the format, position, and size of the image.
const { jsPDF } = require('jspdf');
const doc = new jsPDF();
// Image must be in base64 format or a URL
const imgData = 'data:image/jpeg;base64,...';
doc.addImage(imgData, 'JPEG', 15, 40, 180, 160);
doc.save('image.pdf');
Fonts and Styles
This feature allows you to customize the font and style of the text in the PDF. The code sample sets the font to Helvetica, makes it bold, sets the font size, and then adds the text to the document.
const { jsPDF } = require('jspdf');
const doc = new jsPDF();
doc.setFont('helvetica', 'bold');
doc.setFontSize(16);
doc.text('Styled text', 10, 20);
doc.save('styled_text.pdf');
Vector Graphics
This feature allows you to create vector graphics such as lines and curves. The code sample draws a line with a certain width on the PDF.
const { jsPDF } = require('jspdf');
const doc = new jsPDF();
doc.setLineWidth(0.5);
doc.line(20, 20, 60, 20);
doc.save('line.pdf');
Other packages similar to jspdf
pdfkit
PDFKit is a PDF generation library for Node and the browser that makes creating complex, multi-page, printable documents easy. It has a similar feature set to jsPDF but works with a different syntax and has a focus on vector graphics and text layout.
pdfmake
pdfmake is a client/server side PDF printing in pure JavaScript. It is similar to jsPDF but offers a higher-level API for document definition, which can be more convenient for complex layouts.
html-pdf
html-pdf is a Node module that converts HTML content to PDFs using PhantomJS. It is different from jsPDF as it takes HTML/CSS as input and is useful for rendering web pages as PDFs.

Checking out the source
git clone --recursive git://github.com/MrRio/jsPDF.git
Building
To build, simply run the 'make' command. This will fetch all npm and bower deps, then compile minified JS files.
Running locally
Due to certain restrictions that local files have, you'll need to run a web server. Just run:
npm start
You can then access the site at localhost:8000
